The clinical presentations they encounter are, therefore, varied, ranging from discrete well-defined problems amenable to technical solutions to complex, multifactorial problems with uniqueness to the indi­ vidual that defy the technical rationality of simply applying a 'proven' set course of management. Schon (1987, p. 3) characterizes this continuum of profes­ sional practice as existing between the 'high, hard ground of technical rationality' and 'the swampy low­ land' where 'messy, confusing problems defy tedmical solution'. As will be evident in the case studies of this book, manual therapists must. therefore, be able to practise at both ends of the continuum. Manual ther­ apists must have a good biomedical and professional knowledge base as well as advanced technical skills to solve problems of a discrete, well-defined nature. However. to understand and manage successrully the 'swampy lowland' of complex patient problems requires a rich blend of biomedical, psychosocial, pro­ fessional craft and personal knowledge, together with diagnostic, teaching, negotiating, listening and coun­ seJJing skills. Contemporary manual therapists must have a high level of knowledge and skills across a comprehensive range of competencies, including assess­ ment, management, communication, documentation, and professional. legal and ethical comportment. Effective performance within and across these competencies requires a broad perspective of what

constitutes health and disability and equally broad skills in both diagnostic and non-diagnostic clinical reasoning. In this chapter we present a contemporary per­ spective on clinical reasoning in manual therapy. Clinical reasoning is portrayed as being multidimen­ sional. It is hypothesis oriented. collaborative and rel1ec­ tive. Skilled clinical reasoning contributes to therapiSts' learning and to the transformation of existing perspec­ tives. A framework that describes the organization of knowledge by manual therapists is proposed together with a model of health and rusabiUty/recovery. We consider these will be helpful in promoting a broader perspective on patients' problems and will serve as a reference for exploring the reasoning of individual therapists.

What is clinical reasoning? Clinical reasoning has been defined as a process in which the therapist, interacting with the patient and significant others (e.g. family and other health-care team members), structures meaning, goals and health management strategies based on clinical data, client choices and professional judgment and knowledge (Higgs and Jones, 2000). It is this thinking and decision malcing associated with clinical practice that enables therapists to take the best-judged action for individual patients. In this sense, clinical reasoning is the means to 'wise' action (Cervero, 1988; Harris, 1993). Figure 1.1 depicts the integrated, patient-centred model of collaborative reasoning we hope to promote.

In this model. clinical reasoning is seen as a process of renective enquiry comprising three core elements­ cognition. metacognition and knowledge--carried out in a collaborative framework with the relevant parties (e.g. the patient. carers, other health-care providers, the workplace and funding bodies) (Edwards and Jones,

In attempting to understand patients and their prob­ lems, manual therapists must be able to think along multiple lines and often think on different levels at the same time.

The clinical reasoning process is hypothesis oriented in that patient data prompt the therapist's consider­ ation of compeling interpretations. which are, in turn. claril'icd and lesled lhrough further data collec­ tion and reassessmenl of management interventions (Fig. 1.1). Although many therapists do not realise it, they are generating hypotheses from the opening moments of a patient encounter (Doody and McAteer, 2002; Rivett and Higgs, 1997). That is, initial cues, such as a referral, case notes, observations of the patient in the waiting room, and opening introductions and enquiries with the patient. will evoke a range of initial impressions. While typically not thought of as such, they can be considered hypotheses. These initial hypotheses may be physical. psychological or socially related, with or without a diagnostic implication. They are usually somewhat broad and serve to delin­ eate the boundaries in which the assessment will proceed . All therapists have an element of routine to their examination. Individual therapists will have identi­ fied, through experience, the categories of informa­ tion which they have found to be particularly useful for understanding and managing patients' problems. For example: •

• •

personal profile including work, family and social circumstances site, behaviour and history of symptoms psychological/cognitive/affective status, expect­ ations and goals general medical status: clinical yellow and red flag screening occupational blue flag screening socio-occupational black flag screening functional and structure-specific tests of the cardio­ vascular. respiratory and neuromusculoskeletal systems ergonomic and environmental analysis, etc.

While a degree of routine commonly exists. the spe­ cific enquiries and tests should be tailored to each patient's unique presentation.

Narrative reasoning

Through a process of enquiry. examination and rel1ect­ ive management. the therapist attempts to understand the patient's problem, while at the same time trying to understand the patient's personal story/narrative or the context of the problem beyond the mere chronological sequence of events. Understanding the context. also called 'narrative reasoning' (Christensen et aI., 2002; Edwards, 2001; Fleming and Mattingly. 2000; Jones et al., 2000, 2002). requires attempting to understand the patient as a person. including their perspective of the problem. their experiences (e.g. understanding, beliefs, desires. motivations, emotions), the basis of their perspectives and how the problem is affecting their life (i.e. their pain or illness experience). This dimension of reasoning and understanding requires more than a good biomedical knowledge base and technical skills. Successful narrative reasoning, aimed at understand­ ing the person. requires a good organization of bio­ psychosocial Imowledge and the communication skills in order to apply that knowledge successfully. Narrative reasoning also necessitates a level of openness on the part of the therapist. both v\lith respect to accepting the patient's story and with awareness of their own per­ sonal perspectives, and even biases. on matters such as chronic disability and pain. compensation cases and cultural issues. Therapists' personal perspectives on such issues will influence their approach (e.g. attitudes. expectations, communication/relationship) to their patients and their problems, with rel1ection required to recognize, and where necessary alter. inaccurate or unhelpful perspectives. Patients' understanding/beliefs, attitudes. emotions and expectations represent what Mezirow (1990, 1991) has called their 'meaning perspective' (syn­ onymous with 'frame of reference'). Understanding a patient's meaning perspective is the basis of narrative reasoning. An individual's meaning perspective is acquired and evolves from a combination of personal, societal and cultural experiences. where conscious and unconscious interpretations. attributions and emotions coalesce to make up their views and feel­ ings. Mezirow (1991. p. xiii) states, ' ... that it is not sO much what happens to people but how they interpret and explain what happens to them that determines their actions. their hopes. their contentment and emotional well-being, and their performance'. In this sense. patients' meaning perspectives create sets of habitual expectations that serve as a (usually

tacit) belief system for interpreting and evaluating experiences. In the context of manual therapy, patients' meaning perspectives become f1lters through which their perceptions and comprehension of any new experience must pass. Therefore, if a patient's mean­ ing perspective is distorted-judged by the therapist to be counterproductive to recovery-such as 'pain equals further damage' or 'the damage I have is per­ manent and I will not improve further', then their perception (or lack of ) and interpretation of new experiences (including the therapist's assessment and management) will also be distorted. In fact , distorted meaning perspectives or beliefs are typically more rigid and less amenable to change (Mezirow, 1991). Analogous to attempting to identify underlying physical contributing factors to patients' symptomatic structures, it is necessary for manual therapists to delve into the basis of patients' meaning perspectives (i.e. their understanding. emotions. beliefs and attri­ bu tions) in order to understand these perspectives. Patients' meaning perspectives are re!1ected in their 'story' or the context in which those views were shaped. While sometimes the information comes forward spon­ taneously. therapists must be able to listen for and enquire about (i.e. screen) patients' meaning perspec­ tives and their basis, so as to identify patterns of dis­ tortion that require attention. While some patients' perspectives will fit recognizable patterns, others will be unique and defy some universal truth of 'normal' or 'unhelpful'. In other words. narrative reasoning decisions cannot be reduced to a correct or incorrect empirical judgment. Rather. therapists' hypotheses regarding patients' meaning perspectives can only be validated through therapist-patient consensus, or what has been labelled communicative (as opposed to pro­ cedural) management. As it is beyond the scope of this chapter to cover the full range of psychosocial issues for which therapists should screen, readers are referred to the texts by Butler (2000), Main and Spanswick (2000a), Strong et al. (2002) and Gifford (2000) for more thorough discussions of psychosocial screening.

Diagnostic versus narrative reasoning A distinction can then be made between understanding and managing the problem to effect change (requiring biomedically driven cause and effect thinking and action: diagnostic reasoning and procedural management) versus understanding and interacting with the person to effect change (requiring biopsychosocially driven

narrative reasoning and communicative management). In reality, a comprehensive diagnosis should encompass what is learned from both the diagnostic reasoning regarding the physical problem and the narrative rea­ soning regarding the person. All forms of reasoning and management should be carried out collaboratively. These seemingly different foci of thinking and management (directed to the problem and directed to the person) are not mutually exclusive. as the under­ standing of one enhances the therapist's understanding of the other. For example, attempting to understand and then attempting to facilitate change in the person (e.g. beliefs. emotions and health behaviours) is aided through a greater insight into the problem. The extent and nature of patients' activity and participa­ tion restrictions (World Health Organization. 2001; i.e. physical disabilities and associated handicaps) and impairments forms part of the context in which their psychosocial status must be viewed. A degree of stress and feelings of frustration, anger and even depression may be quite 'normal' in the presence of marked restrictions in activity and participation. Maladaptive thoughts and feelings can also coexist with physical impairment without necessarily driving or being the underlying source of those restrictions. Similarly, however. understanding a problem and then attempting to facilitate change (e.g. activity restrictions and physical impairments) is aided through greater insight about the person. Patients' feelings. beliefs and health behaviours may be contributory to the recovery or detrimental (i.e. counterproductive to their recovery), and judgments regarding these aspects of the patient require effective interpersonal and enquiry skills. including biopsychosociaJ knowledge of what to look for, management strategies and referral pathways. Just as activity restrictions (e.g. dHficulty climbing stairs) must be considered with respect to any physical impairments that may be present (e.g. mobility and motor control), the patient's feelings. beliefs and health behaviours must also be considered \\Tith respect to their experiences and related consequences, which may have contributed to shaping their views and behaviours (Butier. 2000; Gifford, 1998a. 2001. 2002; Main and Booker, 2000; Main and Parker, 2000; Watson, 2000; Watson and Kendall. 2000). Success in promoting change in both the problem and the person necessitates fostering the patient's insight into their own feelings. beliefs and behaviours, including their basis and where change would be beneficial. Reaching this level of mutual understanding requires collaborative

Newell and Simon. 1972: Rumelhart and Ortony. 1977; Shon. 1983). These patterns form prototypes of frequently experienced situations that individuals use to recognize and interpret other situations. In manual therapy. patterns exist not only in classic diagnostic syndromes and associated management strategies but also in the pathobiological mechanisms associated with those syndromes and the multitude of environmental. physical. psychological (cognitive and affective). social. behavioural and cultural factors that contribute to the development and maintenance of patients' problems. For example. it is possible to recognize the typical clinical features of a shoulder subacromial impingement problem. as well as differ­ ent patterns of common anatomical. biomechanical. motor patterni.ng and technique/equipment factors that can contribute to this disorder. Importantly. patients can have the same pathology but quite differ­ ent contributing factors. necessitating different and very individualized management if success is to be realised and maintained. Manual therapists also must be able to recognize patterns of biomedical factors that contraindicate manual therapy. such as clinical red jlags (i.e. serious organic pathology) (Roberts. 2000) and biopsychosocial personal. family and work-related factors (yellow. blue and black nags. respectively) that may predispose to chronic pain. prolonged loss of work and serve as potential obstacles to recovery (Kendall et a1.. 1997: Main and Burton. 2000; Main et a1.. 2000). These are further discussed below under Prognosis. Pattern recognition is required to generate hypoth­ eses and hypothesis testing provides the means by which those patterns are reflOed. proved reliable and new patterns are learned (Barrows and Feltovich. 1987). While expert therapists are able to function largely on pattern recognition. novices who lack suffi­ cient knowledge and experience to recognize clinical patterns will rely on the slower hypothesis testing approach to work through a problem. However. when confronted with a complex. unfamiliar problem. the expert. like the novice. will rely more on the hypothesis­ oriented method of clinical reasoning (Barrows and Feltovich. 1987: Patel and Groen. 1991). Narrative reasoning and communicative management are still required to reveal and act on patients' meaning per­ spectives. regardless of whether pattern recognition or hypothesis testing dominates. Despite pattern recognition being a mode of thinking used by experts in all professions (Schon. 1983). it also represents perhaps the greatest source of errors in our thinking.

Related and other common errors of clinical reason­ ing are discussed in Chapter 26.

Reasoning as a collaborative process Successful management of patients' problems requires more than just good diagnostic and manual skills: manual therapists must also be good teachers. In fact. while a certain percentage of patients' problems can be forever resolved through the sole intervention of the therapist's manual techniques. often lasting changes are only effected by understanding the par­ ticular determinants of health and behaviour operat­ ing and by negotiating changes in the patients' understanding. beliefs/attitudes and behaviours. For example. patients' understanding of their problems has been shown to impact on their self-efficacy. levels of pain tolerance. disability. time off work and even­ tual outcome (Borkan et al.. 1991: Feuerstein and Beattie. 1995; Lackner et aI.. 1996: Main and Booker. 2000; Main et al. . 2000; Malt and Olafson. 1995: Strong. 1995: Watson. 20(0). Manual therapists have generally only learned through personal experience the ski Us of psychosocial assessment and management (e.g. listening. commu­ nicating. negotiating. counselling and motivating) needed to effect positive changes in their patients' health understandings. beliefs and behaviours. While such skills are increasingly being made more explicit in manual therapy curricula. in general these aspects have not historically been given the same attention in terms of theory and application as has clinical reasoning in physical diagnosis and management. Consequently. biopsychosocial knowledge and inter­ personal skills are often tacit and underdeveloped in some therapists. The collaborative nature of the reasoning process is highlighted by the arrows interconnecting the centre and the boxes on the right in Figure 1.1. Whereas the centre boxes feature the therapist's reasoning. the boxes on the right depict the patient's thoughts and understanding. Thus. patients begin their encounter with a manual therapist with their own ideas of and feelings about the nature of their problem(s) and the management they need. as shaped by personal experience and advice from medical practitioners. family and friends. Through a process of evaluating patients' understandings. beliefs and feelings (meaning perspectives). and through the use of explanation.

reassurance and shared decision making. the therap­ ist can involve the patient in developing an evolving understanding of the problem and its management. Beliefs and feelings that are counterproductive to a patient's management and recovery. such as exces­ sive fear of movement or pain. can contribute to phys­ ical deconditioning. poor compliance vvith self­ management. poor self-efficacy and ultimately a poor outcome (Hill. 1998: Main and Booker. 2000). Patients who have been given an opportunity to share in the decision making have been shown to take greater responsibility for their own management and have a greater likelihood of achieving better outcomes (Bucklew et aI., 1994: Burkhardt et al.. 1994; Lorig et al .. 1999: Niestadt, 1995: Shendell-Falil<. 1990), Patient learning is a primary outcome sought from collaborative reasoning (Jones et at.. 2000). Rather than being passive recipients of health care, patients construct a new understanding or meaning perspec­ tive. one in which they are actively involved in man­ agement decisions and share in the responsibility for their health care. While tbis discussion has focussed on the collabora­ tive reasoning between therapist and patient. a Similar collaborative process should exist between the therapist and carers. as well as with other members of the health-care team and funding bodies. This broader role of the manual therapist in the local and global health­ care community as an interactional professional is dis­ cussed more extensively in Higgs and Hunt (1999a.b).

manual therapists. neurological physiotherapists and domiciliary care physiotherapists skilfully employed such reasoning. It occurs on different levels from the provision of simple advice to motor retraining and explanation directed to changing patients' meaning perspectives. In all situations. the therapist must make judgments concerning the level and amount of teach­ ing that is appropriate for an individual patient and the mode of delivery that is most suitable and likely to be accepted by the patient. For example. expert therap­ ists will often strategically use 'stories' regarding other patients as a means of building rapport. educating and communicating prognostic outcomes (Edwards. 2001). Such real-life scenarios bring credibility to the advice or explanation that they are used to support and can be strategically employed by therapists to strengthen their message. Learning theory is discussed in Chapter 25. where transformative learning (described by Mezirow (1990) as perspective transformation) is defined as the con­ struction of meaning (Le. knowledge) from experi­ ence. The individual's revised understanding will then guide their future perspectives (understanding. appreciation and behaviour). Facilitating this level of learning necessitates the learner (patient or therapist) engaging in critical rel1ection. Presuppositions of current beliefs are re-examined. opening the way for new. revised perspectives. Both therapists and patients at times need to renect critically on the basis of their beliefs. so that distortions in meaning per­ spectives (beliefs) may be identified and corrected.

Reasoning as a reflective process

Learning from reflection

Learning should be seen as a central outcome of clin­ ical reasoning for both therapist and patient. While all therapists would hopefully see themselves as both teachers and learners. learning theory has traditionally not been a core area of study for manual therapists. apart perhaps from the formal attention to learning theory that accompanies concepts of motor learning. However. given the importance most therapists would acknowledge teaching has in their patient manage­ ment (Jensen et al.. 1999. 2000: Sluijs, 1991). this is an obvioLls deficiency.

Teaching Teaching is a ubiqUitous activity requiring its own focus of reasoning. Edwards (20CH) found that expert

To learn from your own cUnical experiences and grow as a therapist requires reasoning that is open minded and rel1ective, Reflection is an act of cognition that can be used in different ways, In a simplest form. these thoughtful activities represent reflective thought. for example. when the significance of a piece of informa­ tion is actively considered or when different and sometimes connicting findings are assessed. However. rel1ective thinking at a higher level. metacognition. involves thinking about your thinking and the factors that limit it. Metacognition is a well-recognized char­ acteristic of expertise (Alexander and Judy, 1988: Biggs. 1986). Metacognitive reflections may be directed at any of the following: •

the information available (e.g. awareness of the quality and relevance of information obtained)

the reasoning process (e.g. awareness of specific strategies required to understand the person and the problem and achieve the desired goals) • the hypotheses rormed and decisions reached (e.g. research and experience-based evidence for assess­ ment and management decisions) • the organization of knowledge (e.g. awareness of one's own knowledge base, personal perspectives. biases and any limitations).

Reflection can occur in what Schon (1983. 1987) has called rej1ection-in-action, where you literally pause during a patient encounter and consider any of these issues , or in hindsight as a rej1ection-about­ action. Too often a patient's status changes. for the better or the worse. without the therapist having or taking the time to reflect on the change. In a busy practice. improvement is a godsend as it means the treatment can be repeated with little deliberation. A lack of improvement typically leads to a change in treatment with some consideration of the options available. but often without any serious reflection on prior judgments made and the underlying reasoning that led to the current lack of improvement. The reflective thinker is sceptical. always question­ ing the reliability. validity and overall relevance of findings and interpretations. and ever prepared to accept that their own knowledge base may be inad­ equate. Brookfield (1987.2000) cites this trait as a key component of all critical thinking. not just clinical reasoning. He stresses the importance of being will­ ing and able to identiry and challenge the assump­ tions that underlie beliefs and actions. Reflecting on the basis of one's preconceptions may include con­ Sidering such things as what information is relevant: what constitutes a particular diagnostic, psychosocial or behavioural pattern: what evidence (research valid­ ated or experience based) exists to support judgments and inter ventions: and the appropriateness or the model or health and recovery followed.

Awareness of new perspectives Associated with becoming aware of the assumptions that underlie a belier is the recognition of the context from which those assumptions arose. That is. many of our beliefs are formed from cultural. historical or specific philosophical frames or reference: when these rrames of reference are appreciated. a deeper

understanding of the belier itself and a more informed position from which to evaluate the belief can be achieved. A healthy reflective scepticism, where a par­ ticular philosophy, position or justification is not taken for granted simply because it has been presented by a source or authority or been unchanged for a long time. is important for skilled clinical reasoning and continued profeSSional growth. This is not to suggest that the only legitimate decisions and actions are those that can be conclUSively substantiated by cur­ rent research. as we hold the view that experience­ based non-propositional and personal knowledge. as discussed below. are equally important (Higgs et al.. 200la: Jones and Higgs. 2000). However.it is import­ ant to recognize the basis and biases of one's own views and that alternatives exist. This requires look­ ing beyond your own perspectives and contemplating other possibilities.some or which may even be beyond what is empirically known at the present time. Such open reflection about oneself (by therapists and patients) is no easy task. as Brookfield ( 2000. p. 63) points out: No matter how much we may think we have an accurate sense of our practice. we are stymied by the fact that we are using our own interpret­ ive filters to become aware of our own interpret­ ive filters! ... To some extent we are all prisoners trapped within the perceptual rrameworks that determine how we view our experiences. A selt� confirming cycle often develops whereby our uncritically accepted assumptions shape clin­ ical actions which then serve only to conl1rm the truth of those assumptions. Because of this. it is usually difllcult to explore your own assumptions effectively. Clinical reasoning in gen­ eral. and self-reflection in particular, is enhanced when we enlist the help of others. On this basis, Brookfield (2000) describes clinical reasoning as an inherently social process. Peers. teachers and also our patients can be erfective critical mirrors. as we can be to our patients, to foster the critical self-reflection necessary to promote change. Brookfield labels the reluctance most of us have for this (i.e. to exposing our reasoning to the critique of others) as 'impostorship': the deep feeling many clinicians have that they do not really under­ stand a problem or how best to manage it and their rear of being 'found out' by the patient and their col­ leagues. Acknowledging this realil)' is critical ir thera­ pists are seriously trying to improve their own clinical

reasoning. Section 3 discusses ways in which this bar­ rier can be broken down and in which critical reflection, and hence transformalive learning, can be facilitated. A key attribute of experts, and a necessary pre­ requisite to skilled clinical reasoning, is the affective disposition to think in this reflective manner. Such an affective disposition includes inquisitiveness, self­ confidence, open mindedness, flexibility, honesty, diligence, reasonableness, empathy and humility (Brookfield, 1987; Ennis, 1987; Fonteyn and Ritter. 2000; Jensen et al.. 1999). Clearly critical thinking. as well as being rational. is emotive.

Reasoning requires well-organized knowledge Research investigating the nature and development of expertise across a range of activities (chess, engineer­ ing, mathematics, medicine, physics, statistics) has consistently shown that it is not the command of any generic problem-solving strategies or how much knowledge is possessed that is critical; rather. it is how that knowledge is organized (Allwood and Montgomery. 1982; Arocha et aI., 1993; Bloom and Broder. 1950; Bordage and Lemieux, 1991: Boshuizen and Schmidt, 2000: Chi et al.. 1981: De Groot. 1965; Patel and Groen. 1986; Patel and Kaufman. 2000; Schmidt and Boshuizen. 1993). As previously discussed, humans store knowledge in chunks or patterns. Therefore, one can think of therapists' organization of lmowledge as the breadth and depth of their understandings and beliefs, held together in patterns acquired through both formal academia and personal experience. remembering that diagnostic patterns represent only a fraction of one's knowledge base. In fact. knowledge focussing purely on biomedical. diagnostic pathology is insufficient for full understanding and manage­ ment of patients' problems. Rather this propositional textbook knowledge must be integrated into a broader organization of non-propositional craft and personal knowledge. Understanding of patients' personal con­ texts, strategies of reasoning and intervention. and awareness of your own perspective. are important aspects of professional craft and personal lmowledge. It is beyond the scope of this chapter to explore this importanl topic of knowledge types and knowledge acquisition fully, and readers are referred to the work of Boshuizen and Schmidt (2000).

For the purposes of this book, we will use the broad distinction (proposed by Higgs and Titchen (1995)) of propos­ i tional knowledge (or 'knowing that'-biomedical and biopsychosocial knowledge ratified by clinical trials and well-founded theories of professional practice) and non-propositional knowledge, including professional craft knowledge (procedural knowledge or 'knowing how', such as practical skills and strategies of enquiry, reasoning and intervention) and personal knowledge (knowledge derived from personal experiences, which shapes your own unique meaning perspectives and influences your interpersonal interactions, personal values and beliefs). Understanding and successfully managing patients' problems requires a rich organization of all three types of knowledge. Propositional LmowJedge provides us with theory and levels of substantiation by which the patient's clinical presentation can be considered against research-validated theory and practice. Non­ propositional professional craft knowledge allows us the means to use that theory in the clinic while providing additional, often cutting-edge (albeit with unproven generality) clinically derived evidence. Per­ sonal knowledge allows a deeper understanding of the clinical problem to be gained within the context of the patient's particular situation and enabling us to practise in a holistic and caring way. As important as knowledge obviously is to success­ ful clinical reasoning, improving one's organization of knowledge requires a clear understanding of how knowledge is acquired. Glaser (1984, p. 99) states that 'effective thinking is the result of conditionalized knowledge-the knowledge that becomes associated with the conditions and constraints of its use'. That is. knowledge is made particularly meaningful and accessible when it is created or acquired in the context for which it must be used (Cervero, 1988: Rumelhart and Ortony. 1977; Schon, 1983, 1987; Shepard and Jensen. 1990; Tulving and Thomson, 1973). In manual therapy. this means acquiring and constructing Jinks between propositional, professional craft and personal lmowledge in the context of real-life patient problems. This view is consistent with the stage theory of knowledge acquisition and development (Boshuizen and Schmidt, 2000). This proposes that medical students initially function predominantly on biomed­ ically dominated propositional knowledge structures. which gradually become encapsulated into clusters of higher-order concepts (e.g. clinical syndromes). In other

words, with clinical experience, textbook knowledge is eventually transposed into clinical patterns anchored within memory through real clinical experiences (Bosh uizen and Schmidt. 1 992, 2000: Schmidt et al.. 1 990, 1 992), The notion of an 'illness scri pt' is used to depict this higher-order knowledge structure (Feltovich and Barrows, 1 984). Illness scripts have three components: enabling conctitions: conditions or constraints under which a disease or problem occurs, such as personal, sociaL mectical, hereditary and environmental factors • fault: the pathobiological and psychosocial processes associated with any given disease or disability • consequences of the fault: signs and symptoms of the particular problem as well as its f unctional impact on the patient's life.

Even this probably oversimplifies the complexity of a clinician's knowledge organization. Virtually every characteristic of a patient ' s presentation (enabling conditions, rault and consequences) can be said to exist along a continu um. and judging the relevance of a particular feature often relates to its qualitative characteristics and perceived dominance within the presentation (Bordage and Lemieux , 1 986: Bordage and Zacks, 1984). Therefore. in addition to recogniz­ ing clinical presentations, therapists must also pos­ sess a broader understanding of the determinants of health and recovery. Patel and Kaufman ( 2000) challenge the model or knowledge encapsulation put forward by Boshuizen and Schmidt (2000), suggesting it represents an ideal­ ized perspective on the integration of basic science in clinical knowledge and argue that biomedical know­ ledge and clinical knowledge are two separate worlds. They suggest basic science has different Significance in different domains, and cite research which has demonstrated that even 'expert' medical clinicians have poorly developed biomedical knowledge. They propose that the key role played by basic science may not be in facilitating clinical reasoning per se but in facilitating explanation and coherent communica­ tion. The debate regarding the role of biomedical knowledge is equally important to manual therapy curricula, where some are grounded in promoting clinical decisions on the basis of the patient's presenling signs and symptoms (i.e. impairment based with con­ sideration of but not driven by biomedical factors) while others have pathology and biomedical con­ structs as the focus of assessment and management.

model ' We support a model of knowledge organization (and hence curriculum development) that draws on both traditions but is arguably broader in scope. An excit­ ing new model proposed by Gifford ( l 998b), the mature organism model (Fig. 1 . 2), provides a concep­ tual framework that we consider will assist therapists to take up this broader perspective. It depicts the interactions of the fundamental pathways (input. processing and output) into and out of the central nervous system (eNS) that are necessary lor survival and for the maintenance of health , as well as for the development and continuation of poor health (e.g. pain and disability). Input mechanisms (i.e. all sensory pathways) sam­ ple tissue health and conununicate this together with contexlual information about the environment. includ­ ing the immediate environment surrounding an injury and the ongoing environment that makes up a per­ son's pain or illness experience. The brain can then be said to scrutinize (both consciously and unconsciously) incoming information , along with existing engrams of past experiences, for processing to the output m(,c/I­ arzisms (i.e. somatic motor, autonomic, neuroendocrine, neuroimmune and descending feedback/conlrol sys­ tems). Importantly, how the person's health is then manifest via these output mechanisms (behaviourly, cognitively. emotionally and phYSiologically) depends, in part, on the contextual factors within the person's immediate circumstances, as well as past experiences that have contributed to the person's beliers , attitudes,

1 INTRODUCTION TO CLINICAL REASONING

emotions and behaviours. In other words. even given the same extent of tissue injury or illness. no tvvo people will have exactly the same presentation because how they manifest their pain or illness is shaped in part by who they are. Hence. it is inadequate to focus simply on physical diagnosis. Managing patients' problems also requires understanding their unique pain or ill­ ness experiences (thcir understanding. beliefs. feelings. and coping strategies). While all input. processing and output mechanisms will be in operation in any state of ill-health. they will not all necessarily be impaired (i.e. contributing to the problem and/or counterproductive to recovery). Hence. manual ther­ apists must have the necessary knowledge organization and reasoning skills to distinguish between adaptive/ helpful and maladaptive/unhelpful mechanisms and responses. Even those problems that are seen as primarily nociceptive or residing in the tissues can be occurring alongside maladaptive psychological or behavioural 'responses '. which provide powerful barriers to active rehabilitation and the restoration of physical confidence. For example. a patient may have a lack of insight into the factors inOuencing their problem. which can create obstacles to their improve­ ment until addressed through narrative reasoning and communicative management. At a more physical levcl. prolonged stress not only can lead to increased levels of tissue sensitivity (i.e. secondary hyperalgcsia) but can also predispose to diminished tissue health via associated impairment within the neuroendocrine system (Butler. 2000: Gifford. 1 998c: Main et al.. 2000: Martin. 1997; Sapolsky. 1998). Here assessment of stress as a con­ tributing factor (along with the associated cognitive. behavioural and emotional effects) is clearly essential to understanding and managing the problem. Based upon this knowledge and reasoning. the clinician is then able to make sound decisions (for and with the client) that relate to assessment of the complete problem. including aSSOCiated cognitive. behavioural and emotional effects. and appropriate management strategies. Understanding and managing patients' problems requires a broad perspective of the multiple determinants of health and recovery. together with effective reasoning skills to apply that knowled ge. The mature organism model was developed to encourage and allow therapists (and patients) to be able to con­ sider openly and without prejudice the multiple factors and multiple levels involved in all pain presentations. it provides a broad conceptual framework from which

any of its elements (e.g. tissue mechanisms. pain mech­ anisms. effector mechanisms and psychosocial factors) and their respective clinical features or inter-relation­ ships can be explored fur ther (Jones et al.. 20(2).

• Hypothesis categories From the mature organism model. clinical patterns can be idcnlilled within the three categories of pain mechanisms (input. proceSSing and output). Under­ standing patients' problems requires understanding their unique presentations. including any activity/ participation restrictions. their individual perspectives on their experiences and the physical impairments they may have. This information can then be interpreted with respect to which pain mechanisms are dominant. what structures or tissues sources may be associated with specific physical impairments found. possible contributing factors. precautions. management and prognosis. This can be considered as representing 'categories of hypotheses' (see Table 1 .1) that musl be appreciated to understcUld fully patients and I'heir problems and to identify Clppropriate management strategies. The concept of hypothesis calegories was first introduced by Jones ( 1 9 8 7). but since then the specific categories considered important to manual therapy practice and the terminology used to des­ cribe them has continued to evolve (Butler. 2000: Christensen et al.. 2002: Gifford. 19 9 7; Gif ford and Butler. 19 9 7 : Jones. 19 9 2. 1995: Jones et al .. 2000. 2002; World Health Organization. 2001). These hypotheses should be formulated within broader conceptual models of health and disability, such as the mature organism model (Gifford. 1 9 9 8a) discussed here. Hypothesis categories can assist ther­ apists to relate the various elements of G ifford's model to the particular types of clinical decision required in contemporary manual therapy.

Activity and participation capability/restriction Activity restriction refers to difnculties an individual may have in executing activities. where participation restriction refers to problems an individual may have with involvement in life situations. These terms replace the previous terms disability and handicap. respectively. and are also synonymous with the 'dysfunction' hypothesis category. which has been previously used

1 INTRODUCTI ON TO CLINICAL R EASONING

and specific physical impairments are an expression of their pathobiology and life circumstances. This hypoth­ esis category comprises data about tissue and pain mechanisms. It was designed to facilitate reasoning that would include consideration of the mechanisms by which the patient's symptoms and signs are being initiated and/or maintained by the nervous system.

Tissue mechanisms Tissue mechanisms relate to issues of tissue health and stages of tissue healing. In particular. how well the patient's presentation 'fits' with what would be expected during the corresponding stage of the normal tissue healing process (Gogia. 1992: Hardy. 1989: Vicenzino et aI., 2002) is integral in developing a hypothesis of the pain mechanisms at work. For exam­ ple, an inllammatory presentation in a disorder that has been present for months or years should elicit consideration of other factors (e.g. behavioural, bio­ mechanical, maladaptive central processing) that may be maintaining an inflammatory process or mimicking one through central sensitization.

Pain mechanisms Pain mechanisms refer to the different input. process­ ing and output mechanisms underlying the patients' activity/participation restrictions, unhelpful perspec­ tives and physical impairments. Input mechanisms include the sensory and cir­ culatory systems that inform the body about the envir­ onment. both internally and externally. Examples of two input pain mechanisms are nociceptive pain and peripheral neurogenic pain (Butler, 2000; Galea, 2002; Gifford. 1998d; Wright. 2002a). The basic mechanism operating when a high-intensity stimulus, such as a pinprick, activates high-threshold primary afferent nociceptors resulting in pain is well recognized. The same mechanism is in operation with acute injuries, where injury to target tissues, such as ligament, muscle or connective tissue surrounding nerves, will result in nociceptive pain. Peripherally neurogenic pain refers to symptoms that originate [rom neural tissue outside the dorsal horn or cervicotrigeminal nucleus, such as may occur with spinal nerve root compression or peripheral nerve entrapment. Both nociceptive pain and peripherally evoked neurogenic symptoms have a familiar pattern of presentation. with a predictable stimulus-response relationship, enabling consistent

aggravating and easing factors to be quickly identified by patient and therapist. Processing of input occurs in the CNS, and therap­ ists should be aware of the clinical features indicative of abnormal CNS processing. For example. abnormal processing can occur in patients displaying centrally evoked symptoms (Butler, 2000; Gifford. 1998e; Wright, 2002b), where the pathology lies within the CNS. Here the symptoms provoked from a past target tissue injury can be maintained even after the ori­ ginal injury has healed and the symptoms may no longer behave with stimulus-response predictability. Another example of the clinical relevance of the pro­ cessing mechanisms is evident when we consider that pain and disabUity have more than just physical and sensory dimensions (Merskey and Bogduk. 1994). Pain and activity/participation restrictions in all their forms also have affective (e.g. emotional impact such as fear, anxiety and anger) and cognitive (e.g. under­ standing , beliefs and attributions about the pain or disability) dimensions. Patients' feelings and thoughts about their pain and activity/participation restric­ tions can significantly contribute to the maintenance of their problems and influence the speed of the recovery (Butler, 2000; G ifford, 1998c; Main and Booker, 2000). While all pain can be exacerbated chemically by emotional and/or general physical stress, in a central pain state both physical and psychosocial stress are thought to be Significant contributing factors in maintaining the pain. Hence, a patient's perspectives, including their cognition (e.g. understanding of the problem and intervention required) and affect (e.g. feelings about the problem, management and effects on their life), are important dimensions of all pain states but are particularly significant in central pain. Ouput mechanisms operate through the motor, autonomic, neuroendocrine and immune systems (Butler. 2000; G ifford, 1998c). The somatic motor mechanism involves altered motor activity (increased or decreased) and movement patterns in response to pathology, but also learning. While painful pathology can inhibit muscle function and lead to altered move­ ment patterns (Hides and R ichardson, 2002) , many postural and movement abnormalities are associated with problems of motor learning as well as motor control (Shumway-Cook and Woollacott, 2001). These faulty movement patterns may be acquired through habitual postures and activities of life or may develop as a consequence of maintained pain.

The au tonomic mechanism is a controversial output system in that features of abnormal sympa­ thetic activity are common in some chronic pain states. although the underlYing pathology is still u nclear. While the sympathetic nervous system is normally active in all pain states. it can be pathologically active in some. This pathological activity can contribute to disability. impairment and maintained pain (B utler. 2000; Gifford, 1998c: Wright. 2002b).

Other conseque nces of a stressed system The neuroendocrine system is responsible lor the regu­ lation of metabolism, water and salt balance, blood pressure, response to stress and sexual reproduction. Of these functions, its response to s tress is pHrticul arly relevant given that many patients have elements of stress that are a predisposing factor to. or lhe result of. their problems. Like the sympathetic nervous system. the neuroendocri ne system is responsive to our thou ghts and feeli ngs. Stress, for example. triggers a chain of events from the hypothalamus to the adrenal cortex that enables the appropriate channelling of energy for an individual to escape a perceived threat. However. maintained stress, as is common in so many chronic pain states, can result in mal­ adaptive neuroendocrine activity that is detrimental to tissue health and impedes tissue recovery (Butler. 2000: Giflord, 1998c: Martin, 199 7 ; Sapolsky, 1998). The neuroimmune system is an output system with close links to the brain. the sympathetic nervous system and the endocrine system. ChroniC pain, deconditioning or overconditioning and psycho­ logical impairment can interfere with normal immune and heali ng processes via this system (Butler, 2000: G ifford, 1998c: Mackinnon. 1999: Mar tin, 1997). The pathobiological mechanisms hypothesis cat­ egory is invaluable in focussing thinking to the devel­ opment of hypotheses about where within the nervous system symptoms are being produced and main­ tained, and what other sy stems rrtight be affected. If a patient presents with a 'normal' adaptive pain mech­ anism, wherein symptoms are the result of pathology of the implicated local tissues, it is appropriate to determine the precise physical impairment/diagnosis and identify a specillc site to direct manual treatment. However. when pain symptoms are the result of 'abnormal' maladaptive pain states, resulting from, and maintained by, altered CNS processi ng. manual

therapists must steer away from the sole usc of a lissue­ based paradigm and instead employ more holistic. less tissue-specific managemen t strategies. While physical impairments may still req uire attention, these patient presentations criticaJly require promotion of cognitive­ behavioural. healthlfitness and motor control change through adultltransformative lear ning. These issues are presented only briefly here: while there are numer­ ous basic pain science papers that support these con­ cepts. readers are referred to the excellent texts by Butler (2000).

Physical i m pai rments and associated structures/tissue so urces

A manual therapy diagnosis should be one that cap­ tures the therapist's understanding of the patient and the patient's problem(s). This would include the ther­ apist's judgment regarding each of the hypothesis categories discussed here. In our v iew, it is not satis­ factory simply to identify structures involved, as this alone does not provide sufficient information to understand the problem and its effect 011 the patient. nor is it sufficient to justify the course of management chosen. The manual therapy diagnosis must include a hierarchy of considerations from the activity/partic­ ipation restrictions, and any associated unhelpful perspectives or psychosocial problems, to specific physical impairments identified and their associated structure/tissue sources. Specific physical impairments in a musculoskeletal context are regional neuromusculoskeletal abnormal­ ities detected through the physical examination, such as lirrtited hip active movement, poor transversus abdominis motor control. or excessive glenohumeral joint mobility. The associated structure/tissue sources of physical impairments refers to the actual structure or target tissue from which the symptoms or signs are hypothesized to be emanating, with particular atten­ tion (where possible) to the pathology present within that str ucture. Joints. muscles. ligaments and even nerves are examples of target tissues that can be injured and give rise to pain and physical impairment. Clues to specifiC physical impairment sources are available from the area. description. behaviour and history of the sy mptoms. These hypotheses are then tested fur ther in the physical examination, where

(e.g. mobilization for a stif r. painful movement or con­ trolled loading of a tendinopathy). In other cases, such as symptomatic hypermobile/unstable spinal or periph­ eral jOints , while some treatment in the form of pain­ relieving measures directed to the source of the symptoms may be indicated. the focus of treatment needs to address the contributing factors (e.g. retrain­ ing motor control or mobilization of adjacent areas of hypomobility to reduce the load on the symptomatic tissues). Ultimately, it is only through systematic reassessment of the management provided that the optimal balance of treatment directed to sources and contributing factors is determined. When maladaptive eNS processing is recognized as the dominant pain mechanism. management must be directed to the various patient perspectives. behaviours or physical impairments hypothesized to be contribut­ ing to the maintenance of their activity/participation restriction. However it is often difficult to be certain whether an apparent central sensitization is being driven by external contributing factors or whether sig­ nificant pain and physical impairment may. in fact. be contributing to the patient's stress and psychosocial problems. Again. reassessment is the manual therap­ ist's guide to malting this deCision. With a true noci­ ceptive problem , the signs and symptoms will improve , and continue to improve. in a predictable manner with time and/or skilled treatment. In contrast. when the patient's symptoms do not improve or maintain improvement from a trial of treatment directed toward a par ticular impairment or hypothesized nociceptive source. management must be redirected to the different contributing factors hypothesized to be maintaining the central sensitization (Kendall and Watson , 2000).

Precautions and contraindications to physical examination and treatment Hypotheses regarding precautions and contraindica­ tions to physical examination and treatment serve to determine the extent of physical examination that may safely be undertaken and whether physical treat­ ment is contraindicated or limited in any way by safety conSiderations. Such decisions are determined by consideration of many variables including: the dominant pain mechanism the patient's perspectives and expectations • the severity of the disorder • •

• • • • • •

the irritability of the disorder whether the disorder is progressive (and its rate of progression) the presence of specific pathology (e.g. rheumatoid arthritis. osteoporosis) the stage of healing general health the suspicion of more sinister pathology (e.g. unexplained weight loss).

If treatment is indicated. the therapist must decide whether any constraints to physical treatment exist (e.g. pain-provoking versus non-provocative treat­ ment techniques and the amount of force that can safely be used). A key examination strategy for identi­ fying potential risk factors is the use of screening questions directed to red flags , or clinical signs and symptoms suggestive of possible serious pathology. Redf/ags exist with respect to serious spinal pathology (Roberts , 2000). vertebrobasilar insuffiCiency (Barker et aI. , 2000; Di FabiO. 1 999; Rivett. 1997). certain paediatric disorders (e.g. slipped capital femoral epi­ physis). and the presence of non-musculoskeletal dis­ orders masquerading as musculoskeletal dysfunction (Boissenault. 1995; Goodman and Snyder. 2000).

Management relates to hypotheses regarding inter­ ventions for improving the overall health of the patient. as well as consideration of specific manual therapy measures and techniques. As with all hypothesis cat­ egories , management decisions should not be based on any single facet of the patient's presentation. Rather, information gleaned through the history and physicaJ examination. in addition to the patient's response to trial treatments, will collectively determine the pathobiological mechanisms. relevant iinpairments (and sometimes sources). contributing factors and the need for caution. Management decisions are then gUided via the weighting of evidence from each of these other hypothesis categories, with ongoing man­ agement informed through the reassessment process.

future scenarios based on consideration of the patient's presentation. responses to management interven­ tions and available evidence (clinically and research based). The likelihood of lhese scenarios eventuating depends on the nature of the patient's disorder and the patient's ability and wil lingness to make the neces­ sary changes to those factors contributing to the problem (e.g. physical. lifestyle. personal perspectives/ psychosocial). Prognosis should be considered with regard to the patient's broader prospects for recovery and return to function and/or the patient's potential for learning ' (e.g. changing beliefs and behaviours). which for some may include learning to live and cope with the problem. Like all clinical decision making. prognosis is an inexact science. with both positive and negative prognostic I"eatures typica lly being present in most patient's presentations. Factors that will assist in judging a patient's prognosis include: • •

• •

• • • •

the patient 's perspectives and expectations the patient's social, occupational and economic status the mechanisms of symptoms involved the balance of mechanical versus inflammatory components the irritability of the disorder the degree of damagelimpairment the length of history and progreSSion of the disorder the patient's general health and presence of pre­ existing disorders.

Psychosocial risk factors. or yellow flags (e.g. patients' beliefs/coping strategies. distresslillness behaviour. and willingness to change). should be screened for with all patients (Kendall et al. . 1 9 9 7 ; Main and Burton, 2000: Watson and Kendall. 2000). More recently, Main and colleagues (Main and Burton, 2 000: Main et al. . 2 000) have further delineated the occupational com­ ponent of the yellow flags into blue and b lack flags. BILle flags are derived out of the stress literature. They represent perceived features of work that are generally associated with higher rates of symptoms. ill-health and work loss and which may constitute a major obstacle to the patient's recovery. They are characterized by the follOWing features: • • • • •

high demand and low control unhelpful management style poor social support from colleagues perceived time pressure lack of job satisfaction.

Interestingly, a person's perception may be more sig­ nificant than any objective characteristics of the workplace. again highlighting the importance of psy­ chosocial screening in manual therapy assessment. Black flags include nationally established policy concerning conditions of employment and sickness policy, as well as the specific working conditions of a particular employer: •

national rates of pay - negotiated entitlements (benefit system . wage reimbursement) employer sickness policy restricted duties policy management style organization size and structure trade union support content-speci fic aspects of work ergono mic (e.g. job heaviness, lifting Irequency, postures) temporal characteristics (e.g. number of work­ ing hours. shift pattern).

Through the course of the patient examination and ongOing management. screening for red, yellow. blue and black flags. along with the physical examination and response to initial trial treatments. will assist the therapist in formulating a prognosis and determining the appropriate mode of management. Successfully obtaining this breadth and depth of information requires specific enquiries. For example, has the ther­ apist assumed or explicitly explored what the patient wants to do in the future? Further. with consideration of the patient's meaning perspective. is the patient's personal construction of their situation distorting their own view of what the future holds for them and thus distorting their decision making? Therapists must be adept with the various strategies of reasoning (e.g. diagnostic. narrative. collaborative) in order to achieve the necessary level of understanding required to make decisions effectively within each of the different hypothesis categories. The reflective therapist will not only weigh the full spectrum of prognostic variables in j udging a patient's prognOSis but also critical ly re-examine the j udgment when ongoing reassess­ ment reveals the projected prognosis is not being met. Often manual therapists' assessment and manage­ ment decisions require an element of ethical reason­ ing. The scope of ethical decisions faCing manual

therapists can range from decisions regarding use of potentially aggravating or even life-threatening pro­ cedures to decisions of patient autonomy, informed con­ sent, confidentiality, interprofessional relationships, practitioner-client relationship , resource distribution/ cost containment and a myriad of day-to-day decisions that underpin quality care. Clinical decisions that are based solely on the therapist's judgment of what is best for the patient are not consistent with ethical decision making. Rather, decisions made for the client must be made with the client. We take the view that, as in other areas of decision making, competent man­ ual therapists should be guided by a combination or community and professional standards (e.g. profes­ sional association ethical guidelines) applied in a context-sensitive manner as learned through previ­ ous experiences. We are, therefore , in accord with Benner (1991. p. 18) who states, 'Ethics in health care must start with a practice-based understanding of what it is to be a person, what constitutes the rela­ tionships among the health care worker, patient, family, and community, and what constitutes care and responsibility toward one another'.

Summary Manual therapists must work with a multitude of patient and problem presentations, many of which defy simple technical solutions. Contemporary man­ ual therapy requires that therapists not only have a rich organization of clinically relevant biomedical and psychosocial (Le. biopsychosocial) knowledge but also have skills in diagnostic, narrative, collaborative, prog­ nostic and ethical reasoning. Successful application of that knowledge then requires advanced procedural

(e.g. manual techniques and motor control retraining) and communicative (listening, clarifying, explaining, negotiating and counselling) skills. Underpinning all dimensions of clinical reasoning is the abilily of therap­ ists to recognize relevant cues (behavioural, psycho­ logical, physical. social. cultural. environmental, etc. ) and their relationship to other cues, and to test or verify these clinical patterns through further exam­ ination and management. In this sense, clinical reasoning in manual therapy is hypothesis oriented. For all the various strategies manual therapists util­ ize in their patient management, perhaps the most pervasive are our skills in teaching. Reasoning related to teaching is enhanced when therapists understand concepts and strategies of learning theory, particu­ larly transformative learning, which aims to change individuals' meaning perspectives. How well practi­ tioners learn from the results of their decisions depends on the thoroughness of their deliberations and the time and attention given to their conscious rel1ection. There are no short cuts to becoming an expert manual therapist. However, it is our view that critical, rel1ective and collaborative reasoning will improve the breadth and depth of clinical patterns (regarding the person and the problem, including management strategies) that can be recognized and applied. It has been estimated that master chess play­ ers have some 50 000 configurations of chess that they can recognize (Posner. 1988). While the breadth of clinical patterns that experts such as those repre­ sented in this book possess has not been calculated, it is reasonable to assume their organization of clin­ ically relevant knowledge would be equally stagger­ ing. It is our opinion that expertise is not acquired by experience alone. Rather. expertise is developed, in part, through skilled rel1ective reasoning.

Back and bilateral leg pain in a 63-year-old woman Mark Bookhout

SUBJECTIVE EXAMINATION

A 63-year-old retired female (Francis) presented to our clinic with a chief complaint of low back pain and bilateral lower extremity pain. She had led an active lifestyle and was happily married. with her husband in good health. She played tennis. travelled and was taking computer classes. Francis gave a history of low back pain, chronic in nature, resulting from a lifting injury 22 years previ­ ously. At the time of her original inj ury, she was d iag­ nosed by an orthopaedic surgeon as having a herniated lower lumbar disc, but she was unaware of the actual level of herniation. Francis reportedly had been able to self-manage fairly well with intermittent low back pain until her most recent episode, which commenced approximately 4 months before her first consultation with me. At that time. s he developed sharp shooting pains into both of her lower extremities without any apparent trauma or predisposing factors that she could recaU, otber than the fact her symptoms were exacer­ bated by playing tennis. Francis also noted an increase in her low back pain but reported that her leg pain was more severe and d isturbing to her because she had not had any leg symptoms previously. The pain was described as radiating down into the bu ttocks and the posterior legs as far as the calves and heels, but not into the reet. seemingly following an LS or Sl dermatomal distri.bution. Francis was seen by a physician, who ordered an enhanced computed tomography (CT) scan of the lum­ bar spine with myelography. The scan revealed central spinal canal stenosis along with mUltiple level lumbar

degenerative disc disease and a grade I spondylolisthe­ sis at LS-S1. Francis then had an epidural steroid injec­ tion (4 months ago), which gave her some relief with a notable decrease in pain intenSity, but the distribution of the referred pain was unchanged. She reported the pain had been relieved approximately 40-50% by the epidural injection. Subsequently she was placed on an anti-inllammatory medication (nabumetone). which she was still taking when therapy was initiated . Francis reported that the medication helped her quite a lot. decreasing the intensity of her pain by another 20%. She had not received any previous physical therapy treatment ror her condition and she was self-referred. A physician had apparently told her that she might be a surgical candidate and her primary goal in seeking physical therapy treatment was to avoid having lumbar spine surgery if at all possible and to be able to continue to play tennis, her main passion in life. Francis reported that her back pain was aggravated by slow wa lking, prolonged standing greater than 1 hour. playing tennis and bending slightly forward as in doing her dishes or vacuuming. She reported that her leg pain was specifically accentuated during and after playing tennis, and she could only play 15-20 minutes before noting a significant onset of leg pain. Sleeping was reportedly not a problem and neither was sitting, but lifting heavy loads aggravated her back pain. Coughing and sneezing had no effect on her symptoms. Overall, she rated her level or pain at 4110 but it could l1uctuate from 0/10 on a good day to 5/10 on a bad day.

Clinical reasoning commentary

The clinician's answers to these questions reflect the breadth or his reasoning through the subjective examinatioll, Importantly, he does not simply accept what the patient spontaneously ofl'ers further by screening for other types of symptom, aggravating factors and general health considenl­ tions. j\llulliple structures are considered as possibly being responsible lix the patient's symptoms and these are .directly linked to associated structural

tEl

(e.g. spondylolisthesis) and dynamic (e.g. core trunk muscular stabilizers) contributing factors. Similarly, the clinician's consideration of potential contribut­ ing factors is broad in scope, ranging from the patient's age (and associated degenerative state of her spine) to the stability and mobility of her spine. Her lifestyle. in this case her activity level and pas­ sion for tennis, are also included, providing a num­ ber of options with respect to management Hnd an awareness of the patient's personal goals.

PHYSICAL EXAMINAT ION

Francis was evaluated from a biomechanical perspec­ tive because she was found to be neuro[ogically intact, demonstrating no subjective or objective numbness or sensory deficits and no motor weakness in the [ower extremities. Rellexes were not tested. She presented with a mesomorphic body build and was right handed. Standing

In standing, a hyperlordosis with a palpable step at the L4-L5 segmental level was evident. There was banding of the musculature across the lower lumbar spine and an apparent flattening of the lumbosacral junction. Forward flexion mobility was full range (fin­ gertips touching toes) and without pain provocation, but the standing forward bending test for the sacro­ iliac jOint was positive on the right side. The one-legged stork test, another sacroiliac joint screening test, was also posiLive on the right side. Both the forward bend­ ing test and the one-legged stork test are screening tests for possible involvement of the sacroiliac joint but are non-specific for any particular dysfunction. During the forward bending test. the right posterior superior iliac spine (PSIS) travelled further than the left; with the one-legged stork test on the right side, the right PSIS moved superiorly rather than inferiorly when the patient lifted the right knee up towards the chest. Both of these findings indicated resLTicted mobil­ ity of the right sacroiliac jOint (Bourdillion et al.. 1992; Greenman, 1996; Isaacs and Bookhout, 2001). Lumbar side bending range of motion appeared to be within normal limits, both symmetrical and painless, w:ith normal pelvic coupling noted dnring side bending to either side. The hip drop test, which is a test for side

bending of the lower lumbar spine. appeared, however. to be restricted on the right side. The test is performed by having the standing patient bend one knee and allow the pelvis to drop. Thus, if the right knee is bent the pelvis drops on the right side, invoking left side bending at L5-S1. The test can also be used to indicate whether or not the sacral base anteriorly nutates on the side of the hip drop. so the test is not speCific for any dysfunc­ tion but is again a general screening tool (Jsaacs and Bookhout. 2001). Lumbar extension was not pain provocative but was significantly restricted at the lum­ bosacral junction. with most of the extension move­ ment appearing to occur in the upper lumbar spine. Sitting

In sitting, the forward bending test appeared to be positive on the right side. With this test, the operator palpates each PSIS with their thumbs and the patient is asked to bend forward. The operator's thumbs follow the PSISs throughout the range of forward bending. In this case. the right PSIS moved superiorly and anteri­ orly further than the left, indicating resLTicted jOint play motion on the right side. This test is an additional screening test for sacroiliac joint dysfunction but is also non-specific (Bourdillion et aI., 1992; Greenman, 1996; Isaacs and Bookhout. 2001). Palpation of the inferior lateral angle (ILA) of the sacrum with the patient in a fully flexed lumbar position revealed asymmetry with the left ILA posterior and inferior. Positional testing of the lumbar spine in full l1exion revealed no asymmetry of the lTansverse processes from approxin1ate[y L2 to L5, but there was asymmetry at L1. which appeared to be rotated to the right.

Active trunk rotation in sitting appeared to be sym­ metrical bilaterally with no pain provocation. Supine In supine lying, the passive range of motion of the lower extremities revealed a restriction for combined movements of hip flexion, adduction and internal rotation on the right side compared with the left. The patient complained of 'pinching' in the anterior hip and groin on the right side du ring these combined hip movements. Passive straight leg raising was to 80 degrees bil aterally without pain provocation. Palpation of the pubic symphysis revealed an inferior pube on the right side, with significant tenderness to palpation of the right inguinal ligament. Palpation of the lower abdominal quadrant revealed a marked increase in tone and tenderness of the psoas and iliacus muscula ture on the right side. Anterior to posterior translation of the innominates revealed a restriction on the right side compared with the left. There was also a loss of anterior to posterior glide of the right hip joint relative to the left jOint. Ac tive heel slide in supine lying revealed a significant imbalance i n muscle control on the right side versus the left, with Francis unable to maintain a neutral spine on the right side while performing an active right heel slide through full range without the innominate rotating an teriorly. This test is thought to indicate an imbalance between the abdominal and hip flexor musculature, in this case on the right side (Bourdillion et ai., 1992; Greenman. 1996; Isaacs and Bookhout . 2 001). Prone In prone lying, the leg lengths appeared to be symmet­ rical. as did the ischial tuberosity heights. There was some increase in tension noted on palpation of the right sacrotuberous ligament and there was significant tight­ ness and tenderness noted on palpation of the right long dorsal sacroiliac ligament. The long dorsal sacroiliac lig­ ament is thought to become taut with posterior nuta­ tion of the sacral base (Vleerning et aI., 1996). Palpation of the ILAs of the sacrum revealed the left ILA to be pos­ terior and inferior. Passive mobility testing of the sacro­ iliac joints i n prone lying indicated a loss of anterior nutational movement of the right sacral base. Positional testing of the lumbar spine in a prone prop position, where the patient supports their head and chin on their hands while propped up on their elbows, revealed that

the transverse processes of L5 were asymmetrical. with the right transverse process of L5 being posterior when compared with the left transverse process and the sacral base below. This positional finding is indicative of a loss of the combined movements of extension, left-side bend­ ing and left rotation at L5-S1, secondary to the inabili ty to close the left facet jOint at L5-S1 (Fig. 2 . 1 ). There was also asymmetry of the transverse processes of 14 found with positional testing in prone on elbows. The left transverse process of L4 appeared to be posterior when compared wHh the right transverse process and L5 below. This positional fmding is indicative of an inabil . i t to close the right facet joint at L4-L5, with a loss of mobility for the combined movements of extension, right-side bending and right rotation. Passive accessory intervertebral mobility testing with unilateral posterior to anterior pressures on the right transverse processes from L1 to Sl produced sig­ nificant local pain at L4 and Sl. Positional testing and passive accessory intervertebral mobility testing of the thoracolumbar j unction revealed an FRS right (spinal segment that is held in a flexed, right rotated and right-side bent position) at approximately Tll-Tl2 , with a loss of the combined movements of extension, left-side bending and left rotation.

r explained my clinical findings to Francis and my rec­

ommendations for treatment. She initially understood her treating diagnosis to be mechanical low back pain with a n L 5-S 1 spondylolisthesis and lateral spinal stenosis a t L 5 -Sl. I did not feel there were any con­ traindications to physical therapy intervention and so she was scheduled to see me initially for eight treat­ ment sessions over a 30-day period. Francis and I jointly agreed her goals for treatment would be for her to be able to play tennis without provoking back or leg pain, and to be able to control her symptoms with a home exercise programme and with decreased usage of her pain medication (nabumetone). We also set another functional goal for her, which was to be able to tolerate standing on her feet for prolonged periods or time, up to 1 to 2 hours. without leg pain. such as when window shopping. washing the dishes and hoov­ ering. I anticipated that these functional goals would take approximately 1 month to ach ieve and that the prognosis for improvement and accomplishment of these goals was good to excellent. Following the evaluation, treatment was initiated and consisted of muscle energy tech niq ues to treat an FRS right at L 5 -S1 and an FRS left at L4-L 5 . so as to restore extension mobility from L4 to Sl.

Francis was treated ly ing on her side. specifically localizing forces first to L5-S1 and then to L4-L 5, with extension from above down and from below up combined with the appropriate side bending and rotation (Fig. 2 . 2).

The inferior pube on the light side was also treated with muscle energy techniques. by resisting active hip extension and then upon relaxation correcting the inferior pube by pressing the ischial tuberosity in a superior and medial direction. The reader is referred to Greenman ( 1 9 96) and Isaacs and Bookhout (200 1 ) for further detail of these techniques. Francis received deep soft tissue mobilization to the iliopsoas muscula­ tu re. especially on the right side, followed by instruc­ tion in kneeling hip nexor stretching and prone transversus abdominis retraining to practise at home. Specifically, I attempted to re-educate and balance the musculature on the right side of the pelvis, based upon her initial inability to perform a supine heel slide on the right side without anteriorly rotating the innominate.

• Clinician's answer I felt Francis had a good prognosis based upon the fact

that she had a specific goal in mind for treatment (Le. returning to playing tennis). She also had good gen­ eral health habits, appeared to have no psychosocial

factors. and she appeared to have speci11c mechanical jOint restrictions that I felt were d irectly related to her symptoms and clinical presentation .

2 BACK AND BILATERAL LEG PAIN IN A 63-YEAR-OLD WOMAN

• Clinician's answer I place considerable value on mutual goal setting to establish good communication between myself and the patient. I believe this is an essen tial component of the first initial visit. to make sure that the patient and I have the same expectations to measure the effective­ ness of treatment. If mutual goal setting is not done at the onset of treatment, the patient may have a different goal from that of the therapist. with the patient and therapist measuring the success or failure of treatment from two different perspectives (Le. the patient's goal is total pain relief while the therapist's goal is increased tolerance for sitting, walkin g, other activities in daily living). This can create a sense of disappointment over the course of treatment if the patient feels his or her needs are not being met despite 'objective' improvement noted by the treating therapist.

Clinical reasoning commentary

key dimension of clinical reasoning evident in the clinician's philosophy of management is his collabo­ rative approach with the patient. As discllssed in Chapter 1. patients begin their encounter with a man­ ual therapist with their own ideas of and feelings about the nature of their problems and the manage­ ment they want. as shaped by personal experiences and advice from medical practitioners. family and A

On a subsequent visit. latissimlls dorsi sel f-stretching was added as Francis appeared to be Significantly tight on the right side. The latissimus dorsi was found to be tight by assessing bilateral shoulder flexion in supine lying with the lumbar lordosis eliminated. The latissimus dorsi was s tTetched using the technique described by Evjenth (Evjenth and Hamberg. 1 984) to decrease stress at the lumbosacral j u nction. After the fifth visit, and approximately 2 weeks into treatment, Francis reported she was able to play tennis without leg pain and had noted a substantial diminution in her need for pain medication. decreasing her dosage

The hips were then treated, utilizing muscle energy techniques to lengthen the iliopsoas. tensor fascia latae and hip external rotator muscula­ ture, These muscle groups were stretched in prone lying with the opposite leg off the end of the table and supported on the floor (Fig. 2 . 3 ) . In addition. the hips were mobilized in a posterior to anterior direction to improve both active and passive hip extension mobil­ ity. Piriformis self-stretching in supine lying was added to her home exercise programme. along with gluteus maximus retraining while maintaining a neutral lumbar spine with transversus abdominis activation.

effect of any given treatment procedure.

Clinical reasoning commentary

• Clinician's answer At each visit. I reassessed the major clinical findings, which included mobility for extension at L4-L5 and L5-S l, as well as mobility of the right sacroiliac j oint. I also monitored recruitment of the right gluteus maximus and tranversus abdominis musculature and I reassessed the right hip for combined movements of flexion, adduction a nd internal rotation. My expect­ ation was to find improvements in jOint mobility at L4-L5 and L5-S l , as weI! as mobi lity of the right hip and right sacroili�c joint from one treatment session to the next. I attempted to correlate improvements in joint mobility with improvements in function a l performance by asking t h e patient to show active movement (Le. extend the h i p, recheck the forward bending and one-legged stork tests, and recheck the right hip drop test). I feel it is important to show the patient (as well as to remind the patient) of how their original findings have changed , since often a change in movement/mobility, both actively and passively, occurs before the patient's symptoms improve, espe­ Cially in patients with chronic pain.

You have described attempting to re-educate the balance of this patient's lumbopelvic musculature, highlighting examples of training in supine and prone lying. Was it necessary for the patient to progress this retraining to other positions!

• Clinician's answer Although not directly discussed in this case, I gener­ aJly progress patients from non-weight-bearing exercises to weight-bearing exercises and activities, incorporating the patient's exercise programme into functional activities and activities of daily living. I believe this is especially important in retraining muscular control , especially retraining for activities that previously were reported by the patient as pain

For skilled manual therapists, reassessment is sec­ ond nature. However, it is important to recognize reassessment as a form of hypothesis testing by which the therapist's understanding of the problem and the person is either supported or not supported. and management continued or altered accordingly. The breadth and specificity of reassessmcnt will vary according to the nature of the problem alld the pain mechanism j udged to be dominant. In any case. care is needed when hypotheses regarding t he 'source' or pathology are tested through reassessment. Clearly an improvement. in mobility. muscle control or pain response does not conlirm a source or pathology. For t hat. more sophisticated assessment/reasscssment through advunced imaging procedures. electromyo­ graphy or other medical investigations arc needcd, many of which themselves have poor predictive validity. We encourage therapists to hypothesize about specilk structu re/tissue sources and to con­ sider the nature of the pathology, as these deli­ berations will assist therapists' search for a better wlderstanding of the relationship between palllol­ ogy. pain and physicul impairment. However, to avoid misleading yourself that you have c1Tected a change in the pathology or structure of a specific tis­ sue, it is better to view your treatments. as the clini­ cian has here. as being directed t oward a specific impairment (physical or psychological) in order to establish the relevance of the identified impairment to the patient's presentat ion . Encouraging patient understanding. which may require modil1cation to their pre-existing per­ spectives, is an ongoing feature of manual t herapy management. Even subtle strategies, as the clini­ cian has alluded to here when pointing out to the patient changes in the impairment. contribute to improved patient understanding. As discussed in Chapter 1, improved understanding fosters greater self-efllcacy/responsibility and patient participa­ tion in management.

Outcome Francis received 11 treatments over the course of 2 months. When seen for her last appointment. she reported that she was doing extremely well. was no longer taking any pain medication. and no tably had no leg pain complaints even after playing tennis for 1. 5 hours. She had intermittent mild low back pain that she reported was not limiting her activities of daily l iving at all. Francis felt that her exercise pro­ gramme gave her significant control of her symp­ toms. and she now rated her low back pain as 2110 compared with 4/10 initially. Her mechanical find­ ings were reassessed and compared with the i nitial evaluation. She had regained full and pain-free range of motion of the right hip for f1exion. adduction and

internal rotation and showed significant improve­ ment in anterior nutational movement of the right sacroiliac joint. Positional and passive mobility test­ ing of the l umbar spine revealed improved mobili.ty at L4-LS. with only slight restriction on the right side at LS, which was treated on her last visit with unilateral posterior to anterior grade IV pressures (Maitlan d , 19 86) . She now was better able t o recruit t h e gluteus maximus on the right side d uring active right hip extension i n prone lying. and her hip extension range of motion had notably improved, with the ability to extend the hip 10-15 degrees from the prone lying position bilaterally. Francis was discharged from physical therapy 2 months after initiating treatment and instructed to call should she have any further questions or problems in the future.

Ongoing low back, leg and thorax trou bles, with tennis elbow and headache David Butler

SUBJECTIVE EXAMINATION

During my c l inical career, I can recall four particular patients who stand out as prod ucing significant changes i n my understanding of clinical presenta­ tions and my professional direction. The patient described here, with ongoing low back, leg and thorax troubles, plus tennis elbow and headache, is the most recent. Ru by. a 5 2 -year-old sligh tly overweight European woman with a sparkle in her eyes was referred via a physicia n to ascertain the value of continuing physio­ therapy treatment for o ngoing back pain. I noticed immediately that she had little trouble getting up the two llights of stairs in our practice. and when I intro­ duced myself I had the feeling that s he was not too sure about bei ng there. I asked her an opening question, ' What do you feel is your main problem ? ' , and then she began to talk. I did not h ave to ask many questions, she only stopped when she wanted to ask a question, and sometimes I j ust had to nod for her to continue telling her story. I have attempted to group Ruby's story i nto traditional categories. although the story unfolded as s he wanted to tell it. Ruby said she was 'inj ured' at work 14 months ago. She was a s hop assistant. 'Something definitely went in my low back ' . she said, ' when I was l ifting bundles of clothes onto shelves, nothing much differ­ ent from what I do normally, but perhaps the bund les were larger.' Prior to this there were just the ' usual aches and pains everyone gets, but I was fit and could

do anything'. Ruby admitted that work was 'a bit stressy' at the time because she worked in a large department store in which there had been some downsizing, a nd a few of her colleagues around her age had lost their j obs. She was working three half days a week and said that she was j ust managi ng, with not much time for anything else. Her goal was to return to her original three fu l l days of work per week. I asked Ruby to show me where she felt her prob­ lems were (Fig. 3 .1). She described a wide area of dis­ comfort in her lumbar spine and she ran her hand down her right leg in what looked like a combination of the L4 and L5 derma tomes (,I have done this so many time I think I have rubbed it 01T' , she stated ) . There. was a small area j ust rig ht of her lumbosacral segment that she said was particul arly tender and which she encouraged me to touc h. In addition her whole right foot 'didn't feel right', although there was no paraesthesia or a naesthesia. She had had some diffuse mid-thoracic pain for at least 6 months. 'My shoulder blades make cracking noises too', she added. In addition. Ruby complained of left lateral elbow pain present for 2 months, which she said had been 'dismissed as tennis elbow'. She commented, 'You are the first person to seem interested in my elbow. Most people don' t want to know, yet sometimes I think that the elbow can be as bad as the low back.' There were also some headaches and neck pain, but she felt that her lower back was the 'core problem'.

R EASONING DISCUSSION AND CLINICA L R ,E ASONING COMMENTARY

D

What were your thoughts at this early stage!

• Clinician's answer My first thought was that Ruby had a pain state from minimal trauma and that there had been plenty of time for the inj ury to heal. Immediately my thoughts were directed at the possible processes that could be contribu ting to ongoing sensitivity. My i nitial thoughts are summarized in the reason i ng categories below.

Pathobiological mechanisms

Pathobiological mechanisms are likely to involve mul­ tiple processes. Although tissues have had time to heal, they are likely to be unhealthy and there may be significan t physical impairment. To explain her pain state, there are hints of peripheraJ neurogenic (e.g. area of leg pain) and central mechanisms (e.g. spread and

persistence of symptoms) . There is surely nociceptive (tissue-based) pai n , perhaps from combinations of deconditioning, acidosis, neurogenic inflammation, and persistent physical dysfunction. Upregulated nervous systems are likely to involve perturbed out­ put and homeostatic systems, such as the endocrine, autonomic and immune systems. Sources

there is impairment with peripheral neurogenic mechanisms, then a reasoned source is the L4 or L5 nerve root. If there is nociceptive impairment. then any of the mobile tissues may potentially be unhealthy and could perhaps be iden tified on physical examina­ tion. The anatomical sources of the central seflsitivity are impossible to identify, but descending endogenous pain control pathways, the dorsal horn and multiple brain areas, including sensory, motor, attention, mem­ ory and limbic systems, are likely to be involved.

If

Prognosis

On the 'good' side is her disposition, as indicated by her comment 'its been there only 1 3 months' . Perhaps some obstacles to recovery are work difficulties and the widespread and worsening nature of her symp­ toms. r was encouraged at this stage.

Also. you state that she did not have any paraesthesia/anaesthesia. suggesting that you screened for this particular symptom. Could you highlight what sorts of screening questions you would use when the patient does not spontaneously volunteer the information?

Clinician's answer Management

Management strategies are likely to involve education regarding the nature of the inj ury, reasons for pain maintenance and unnecessary fears related to move­ ment. It may involve pacing activities in relation to sensitivity and devising activities that present learnt painfu l movements to the brain in non-painful ways. It will probably involve active and passive treatment of relevant physical impairments. S he will also need to get fitter.

Contributing factors

There are already hints of work-related stress. This lady has quite a diffuse array of symptoms. Can you comment on why you would want to know about all her complaints rather than just her main problem?

• Clinician's answer The biological processes behi nd all the complaints are l i kely to be the same, but all complaints are needed for a working diagnosis. For example, knowledge of the elbow pain could support a hypothesis of central sen­ sitization or a hypothesis of a generalized inl1amma­ tory disorder, or perhaps a local tissue-based pain state from inappropriate use of the part. The big picture is necessary for therapy. For example, it may be the elbow pain that prevents particular activities which may help the low back. Ruby's main problem(s) may weU vary during therapy. This appears to be a clinical feature of central sensitization. If explanation is hypothesized as a key manage­ ment tool, she will want all symptoms and features explained. It is important that Ruby knows that the elbow pain, the headaches and the cracking in the thorax are not new problems, but that they are likely to be an expression of one process.

There are many different questions that may need to be asked if the patient is reticent to volunteer infor­ mation. For example, with respect to other types of symptoms, it may be necessary to ask about pins and needles or whether there are a ny areas that are numb. Clinicians will need to ensure that the patient's comprehension of ' numb' is the same as theirs. This question is related to the sensory aspects of periphera l neurogenic/central contributions. Asking whether there are areas that 'don't feel the same as before the injury' or which 'don' t feel the same as the other side' can a lso be revealing. Other screening questions. seeking hints of autonomic and motor involvement, include changes in sweating, skin health and feelings of weakness.

• Clinical reasoning commentary The breadth and openness of the clinician's ' work­ ing diagnosis' is evident. As suggested in Chapter 1, a manual therapy diagnosis should be one that captures the clinician's understanding of the per­ son (Le. narrative reasoning) and the person's problem(s). This should include, as provided here, the clinician's j udgment regarding each of the hypothesis categories. It is not sufficient simply to identify structures involved, as this alone does not provide sufficient information to understand the problem and its effect on the patient. or to j ustify the course of management chosen. The manual therapy diagnosis must include a hierarchy of con­ siderations. including the activity and participa­ tion capabilities/restrictions, the pathobiological mechanisms, patient perceptions of their experi­ ence (i.e. psychosocial issues ) , specific impairments identified and their associated hypothesized sources, and contributing factors. The clinician's narrative and collaborative rea­ soning is also evident in this patient-centred inter­ view where he encourages the patient: to tell 'her story' in the way 'she wanted to tell it ' .

Ruby felt that there was always some low back pain. although it varied. The leg pain came o n when the back pain increased, or i f she did a lot of bending.

She mentioned that she 'could be watching television and the back and leg might hurt' . Further questioning revealed that sitting was perhaps an aggravating factor and 'staying sti ll could also bring it on' . If she was sitting or doing paperwork while standing at work, she would get uncomfortable and the leg pain would manifest. There were no par­ ticular movements that aggravated her symptoms and she said that her spine felt a ' bi t stiff ' . There were no autonomic or vascular type symptoms. ' [ j ust don't understand it and no-one else seems to either', she comp lained . The only things that would ease the pain were forgetting about it, time. or sometimes a few gin and tonics would 'take the edge off it or make me forget it'. Listening to music,

While a mechanical pattern has emerged it is not a clear pattern with a closely linked stimulus/response feature. It suggests combinations of primary hyper­ algesia (tissue based) and secondary hypera l gesia (central nervous system based ) .

• Clinician's answer These are frequent characteristics of central sensi­ tization. A small amount of alcohol may be a relaxant through central enhancement of the serotonergic system. The key thing i s that these features can be used as part of explaining about what appears to be central sensitivity. It may help to demonstrate to her that focussing on the pain may make it worse, how distractive techniques could be useful. and how she does have some control over the problem. To help to explain increased sensitivity, one could use the example of the more mellow Barry Manilow music being more acceptable than the heavy rock music. This observation could be related to get her to do an

Did you think the difficulties with her bowels and the increased sensitivity of her stomach warranted any concern and follow-up investigation?

No. My reasoning was that bowel-related pain was mechanical and perhaps rel ated to ongoing nerve root sensitivity as it increased leg pain . At this stage, increased stomach sensitivity could be seen as part of a central sensitivity.

She coul.d squat, and there were no great abnormal­ ities detected when r observed her waJl<ing. Balance on either leg was not good, especially the right leg. which she could only balance on for a couple of seconds. Ruby's active lumbar movements seemed reason­ able. Lumbar extension looked stiff, particularly in the low lu mbar region. and I noted that during exten­ sion she sh ifted to the left. away from the painful lower limb. The movement was restricted but no pain was produced. Lateral l1ex ion to the right seemed a bit more restricted than to the left. particu larly in the lower regions. On lumbar flexion, there was a pulling sensation and some diffuse pain across her lumbar spine and buttocks, although she could nearly touch the 11 0or. These symptoms increased when I carefully added cervical flexion. I looked at thoracic rotation only. There was some stiffness and a little mechanical hyperalgesia in the thorax on rotation to the left. In addition, there was also a cramping feeling in the thorax. Ruby could lift her arms above her head easily and without discom­ fort. 'That crackling noise should go when you are moving better' . I ex plained. During cerv ical spine retraction, the thoracic pains were provoked. I

Passive movements I performed a quick palpation examination. There was no excessive warmth in tl1e tissues and I palpated the thorax and lumbar spines both cen trally and u ni­ laterally. Ruby was byperalgesic all along her thorax, especially a t the mid-thorax where it felt particularly

stiff to posteroan terior passive accessory in terverte­ bral movements. The l umbar spine was also hyper­ algesic, particularly the lower lu mbar region and espec ially on the right side. although I could not detect any localized stiffness. There was also multiple area tenderness when I palpated over the sacrum. Neurodynamic testing revealed: Straight leg raise (SLR) of the left leg was 80 degrees with a pulling feeling behind the knee. • Right SLR was abou t 6 0 degrees with some pulling sensation behind the knee and a 'dragging feeling' in the l umbar spine. • Passive neck flexion in supine lying produced a very slight pulling feeling in the lu mbar spine and a mid-thoracic pain at end or range. • The slump test was performed actively with some guidance. On in itial slump 'nothing' was felt. The addition of neck l1ex ion 'pulled ' in the thorax. and left knee extension at minus 1 0 degrees 'pulled ' in the mid-hamstring area. Right knee extension was about minus 20 degrees and evoked symptoms in the back and thorax. There was also a 'vague numbish' feeling in the right foot. All of these symptoms were eased when the cervical spine was extended. even with j ust upper cervical extension . •

Neurological examination

While standing. heel walking revealed some right­ sided anld e dorsillexor weakness, and heel raising also showed some slight right-sided weakness. For both these quick tests, weakness was only evident after five or six repetitions. 'Is it safe to do this?' she asked. 'No problems. you are doing wel l ' , I replied . Her quadriceps rel1exes were equal. although somewhat hyper-rellexic. The ankle jerks appeared equal and normal. There was a slight decrease in strength in all right-Sided muscle groups below L2 . I thought that the L4 muscle test (ankle dorSiflexion)

stood out as the weakest. The tendon oC the contracted right tibialis anterior muscle was softer to palpation than on the left side. There was hypersensitivity in her posterior right leg to a cursory light touch exam­ ination, although this could not be localized to a dermatome. Mild, bilaterally equal ankle clonus was evident. I told her that her ' nerves were firing wel l ' . Pinprick was n o t performed . Ruby said that she was a little sore in the back after the examination. I reassured her that this was natural. Initial assessment

The above subjective and physical examination had taken me about 45 minutes. [ told Ruby that I would need to continue the examination and get some more details next time. As she left, I told her that I wanted to achieve four things for her within the next few visits: 1.

Explain what I thought was wrong as far as the most current scientilk understanding of spinal pain would allow ( th is would include why the problem was stUI persisting):

Clarify how long it would take to improve and what improvements were possible: 3 , Present all the options of what she could do for it. 4. Advise her what physiotherapy could do for the problem. I said that I was sure I could help her and s how her how to manage her problem. 2.

She looked at me somewhat quizzically, said ' thanks' and left. I wasn't sure whether she was going to come back. During the examination, I made notes on what I thought I should specifically attempt to explain to her. These i ncluded: • • • • • • • •

why the problem had not gone the spread of pain what the tennis elbow meant the cracking noise under the scapula why pain came on for no reason why there had been various explanations for the problem why moods affected the pains the radiograph findings.

• Clinician's answer

Yes they IItted. Ruby may have had better general movements than [ thought she would, but this i s understandable with a hypothesis of central sensitiv­ ity. I believe that because I spent a significant amount of time with the subjective evaluation and let her tell her whole story a clinical environment was created which allowed her to move reasonably well. There is clinical evidence of peripheral tissue involve­ ment (e.g. neurological findings, area of symptoms) and a pattern that. on the basis of modern neurobiology in particular, could be argued as central sensitivity.

[ believe that it is a myth that this kind of patient desires hands-on treatment at their first visit. Often many patients have had failed hands-on treatment. In this particular case, my reasoned j udgment was that her desire for information and support was much stronger than for an instant ' fIX it'. If a subjec­ tive enquiry reveals that a patient really wants mobilization, traction or ultrasound, then it may be worth giving it to them, so long as the therapist and patient do not fal l into the trap of bel ieving that this is the l ilcely sale and necessary treatment.

The danger is that the delivery of such techniques, with possible short-term beneficial results from treat­ ment, may reinforce the notion that. tissue damage is the only cause. The patient has to see the place of physical findings in the big picture. as much as clinicians must. Most patients want a good physical eval uation. There is plenty of usel'ul therapeutic touch in the physical exami nation. Perhaps we should rea l i se that the physical examination i s in fact t.reatment. and that the patient is consciously and subconsciously learning from your physical examination.

I had forgot­ ten to ask in the first examination or which need ed confirmation. S he h ad received previous treatments. The thorax and l umbar spine b a d been manipulated many times by various professionals. This would usually give rel ief. though not always. Hydrotherapy was tried but did not help. She had tried various exercises but found ' when I concentrate on the back, it. sometimes gets worse afterwards'. I rechecked the active movements ( no cha nge i n pattern observed at first appointmen t) , performed a Babinski examination (negative) and performed a closer palpation or her l u mbar spine. The left L4-L5 area was the most tender, although the same general­ ized tenderness was evident. Both SLRs were similar to Day 1. perhaps a little better. With the right ankle dorsil1exed and inverted, and then the leg raised, there was significantly more hamstring and back pain than on the other side. r checked the slump test in long-sitting. Pain was evoked in the m id-thora x in this position and could be eased by cervical extension a nd by both left and right knee flexion. I performed a left upper l imb neurodynamic test (Butler. 2000) for the radial nerve. There was a l ittle

more sensitivity over the lateral el bow than on the other side, but no apparent tightness or sliffness. I said that I thought that modern science could provide a reasonable explanation for her problem and that I should go over that IIrs t I a lso said t h a t there were a few things I could do and that there were many t hings she could do to help. The intercha nge below was my attempt to explain the problem: .

Clinicial1 I think after listening to your story and examining you. that there has to be some un heal thy. unfit tissues in your lower and middle back. Certainly there are many tender joi nts and sensitive nerves, and a lthough I haven' t tested muscles yet-I will la ter-they are sure to have lost some of the norma l heal th and vitality they had before your problem began. You probably did strain some joints and muscles in your back a few years ago, as wel l as probably having some nerve irrita tion . which caused the leg pain. and these tis­ sues are still a bit sensitive. However. one thing is for sure, over the last year the inj ured tissues h ave had every cha nce to heal and these present pains a ren't real ly serving the original purpose of the pain, which was a warn ing and a call to action. R uby OK, I would l ike to get things a bit health ier. but how? It j ust h urts so much. And why doesn ' t it get better? There has t o b e something wrong i n there. I am n o t p u tting it on .

3 ONGOING LOW BACK, LEG AND THORAX TROUBLES, WITH TENNIS EL BOW AND HEADACHE

good scientillcally based explanation of why your back is still so sensitive. Ruby I'm all ears. Clinician Your once-injured joints, muscles and nerves have had plenty of time to heal. As you know, even a broken bone will heal up nicely in a couple of months. A lso, by your decreased activity you have protected yourself. maybe overprotected , from re-injury. But for various reasons, which we' ll explore. the tissues are still unhealthy and sensi­ tive. However, they can be made a bit healthier and made to move better, given more blood , and the oil in the jOints can be made healthier and slipperier. They are sensitive but they are crying out for movement. Ruby OK. but why is it still hurting and shouldn't my attempts to move make me feel better? I always used to feel great after exercise. It's not for the want of trying you know. A couple of times 1 have said 'sturr it' and gone and exercised and wal ked lots, but I really pay for it afterwards, sometimes not even sleeping for a couple of nights. Clinician Well , it's partly those sensitive unhea lthy tissues and getting the right balance for the amount of exercise, but it's probably also because there has been a few sensitivity cbanges right throughout your nervous system. Ruby What on earth do you mean by that? Clinician Well , there has been a lot of resea rch into pain mechanisms over the last few years. We now know that when there has been a tissue injury, particularly a painful one such as a joint injury or particularly a nerve compression. and if there has been a bit of stress at the time, that the whole ner­ vous system not only becomes more sensitive, but it can also stay sensitive. Ruby Are you inferring that this is a ll in my head David? Clinician Well no, but yes in a way, in a very real way in your nervous system. I have no doubt about the reality of your pains. This is not easy to explain so bear with me. There are some problems in the tissues but we now know that repeated impu lses into the nervous system will make it more sensi­ tive. more ready for action. It's a natu ral thing. It happens in everyone, but for some reason, in some people, these nerves stay sensitive. If this hcippens, it means that inputs from other parts of the body like the elbow or the thorax can also report pain . Sometimes old pains that you thought

had gone cou ld come back. It is rather like there is an amplifier or a magnifier in your body which makes everything seem worse than it is. Perhaps you could have handled your son's rock music in the past. but now because of your sensitivity being a bit turned up, it is more difficult. Ruby Sounds possible. Maybe that music does bug me more these days. And I did have bad elbow pains about 5 years ago. I am not sure about some scientists though. I j ust want you to know that I am not making this up. Clinician r don't think you are making it up and if some colleagues of mine have suggested that. then that is unfortunate and all I can do is apologise. But a ll pains are real and I am j ust being a mouth­ piece for a lot of recent scientilk work. If you want to read about this, r can give you some short art­ icles which I have written. Ruby Maybe later, perhaps my hus band would be interested. I want to hear more from you . Clin ician Let m e try and express this on a cliagram (Fig. 3 .2 ) . From my examination, I believe that there are a number of tissues that are sensitive and a bit unhealthy. There are also changes related to sensitivity in the spinal cord. r know that sounds awful but, as r said. it happens to everyone. We are l ucky to have this wonderful nervous system that can keep changing its sensitivity depending on how much we need it. r am sure you have heard stories of people who really want to complete a game of sport and during the game they sustain some nasty injury but they can complete the game. We all have the ability to turn the pain system up and down as we need it, and of course some of the changes are automatic. However, sometimes the pain system stays turned up and there is a sort of a magnifier in your system. For example, when I touched your back gently, it hurt. Now there is nothing wrong with your skin otherwise we would see it, but the touch is going into the central ner­ vous system where it is turned i nto pain. Don ' t worry, this is very common. We all get it t o various degrees and we often see patients where minor inputs such as a collar rubbing on the neck or a little draft seems to cause pain. Ruby (After some time looking at the drawing.) So you are saying that the pains I am having are not really the pains I have got. Clin ician (1 was a bit stunned by this response.) Well. yes and no; perhaps more yes. r think that

/ there are some pains/coming from the j oints, muscles and nerves o(the b ack, but you are right and up to date sCientifically if you are thinking that the pains you are experiencing may not be a true rellection of the state of tissue health and healing in the spine. We have to get your whole system less sensitive as wel l as making those tissues more healthy. Are you OK with all this? R u by Yes I think so, but I wan t to discuss this with my h usband. Clinician OK, sure. You can bring him in next visit, if you want. I am going to give you some articles to read and you can give them to him as well. R u by It's comforting to know that I am not alone here. I am looking forward to starting something. What sort of things will I be doing? Clinician You have started already: Sometimes when you know a bit about what is going on it takes a bit of sensitivity out of your system already. R u by Yes that's right I am sure, but shouldn ' t I b e given some exercises? /'

Clinician Let's call it activity rather than exercise. I had to leave the room for 5 minutes. (When I came back, Ruby looked a little concerned.) R u by I don ' t really understand it. I can follow your story about impul ses making the nervous system sensitive. It sounds sensible, but why me? Why hasn't everyone got chronic pain? Clinician Well. there are more people with chronic pain than we ever thought. Approximately one quarter of all Australians have some pain that doesn't go away. In your case, I don't really know for sure, but we can make some educated guesses. First of all, the type of inj ury is likely to be import­ ant. From the sound of it, we .c an guess that the initial injury may have involved irritation of a nerve. That test when I asked you to slump and lift your legs suggests that there is a bit of irritation or tightness around some nerves, plus there is some minimal wealmess and funny feel ings in the foot . That's from nerve irritation in the back. I f you remember, the test was more sensitive on the right side. There are parts of the nerve close to the spinal cord and near the disc (desk model shown) that keep buzzing for a time after injury. Also, when there is a bit of adrenaline around, which there always is when there is an inj ury and if you get a bit stressed or upset, it will also make damaged nerves more sensitive. A nerve can be sensitive for q uite a while but they nearly always get better, especially if you keep reasonably active and under­ stand what is going on. Second ly, the sensitivity within your nervous system can be increased for a number of reasons. You could th ink of them as things that are stressing you, some of which you may not be aware of. Novv I hardly know you, but j ust from our two meetings I can see a few reasons for increased sensitivity. For example, with failed treatments and lack of explanation or direction, it is no wonder that you remain sensitive. If you feel as though you have to prove there is something wrong, it naturally only uplifts your sensitivity and this is often the case where there are problems at work. It's a natural survival thing. Walk through the d ark and you become more sensitive to the surrounds. This must be related to the fear of not knowing. Your brain in a small way is fearing for your survival so it lifts the sensitivity and makes more stress chemicals like adrenaline and cortisol. We haven ' t discussed it but it is only natural that

you would have some concern for the future. I know you love gardening and perhaps even looking at a garden that needs care is stressful. Work issues are probably stressful. There may be other things in your lile that you can think of which may make you a bit sensitive. They may be worth thinking about. Ruby Maybe. At the time of the accident 1 remem­ ber being very angry. It was very painful but 1 don't think they believed me you know. There had been a few women off work and 1 thinl< they thought we were having a go at the system. It was the same when 1 had elbow problems 5 years ago. And by the way, have you had a look a t the X-rays 1 brought in? Clinician Oh yes. let's look together. There are some changes but they are rea l ly j ust the kisses of time. We all get them and there is nothing to worry about in the bones. Your bones look heal thy. An X-ray can't tell much about damaged tissues; sometimes the CT scans can but your CT scan was great. These are typica I for someone your age, with or without pain. Ruby Well. it's a worry with a l l that wear and tear, but I follow you . Clinician 1 said during the first visit that I would try and answer [our things: what is wrong, how long i t will take to get better. w h a t you c a n d o and what 1 or anyone else can do. Hopefu lly. 1 have begun to answer the first. How long it will take to get better is hard to answer, b u t I am sure that you will be able to function much better once you u nderstand the nature of the pain, that you can edge into it. explore it. even play with it and know i t won't harm you . It may never go completely and there will probably be a few l1are-ups, but this does not mean your management is failing. Thirdly, what can you do? From my examination, I believe that you have every reason to remain positive and being positive will help. S imply, posi­ tive people make happy healing hormones. We know your nerves are working; we know there is no serious pathology and you are moving quite well. There are a number of things you can do, but it's really all about movement. Edging into pain with less fear is one way. but 1 think you and 1 could also come up with a paced exercise prog ramme; that is, a series of activities that you know can hurt but which are performed short of pain. It is teaching your brain that activities that normally hurt don't

have to hurt. When we set a n exercise programme. we can make some goals, for example increasing time and activity i n the garden. There may always be some pain and you may need to be more active for a while before it settles. For the moment though. try and minimize activities that cause the shooting pain down the leg. I will also d iscuss other management such as using heat and cold and relaxation. Fourthly, what can 1 do? The big picture aims are to get you a bit fitter, a nd happier to move with greater u nderstand ing of your problem. There are some specinc exercises I will add. but they can wait until next visit. This will include some general slump exercises to improve l1exibility and I think it is worthwhile getting some of the local muscle groups around your low back and the front of you r neck more active. I think t h a t in this k i n d of long­ standing problem, there is unlikely to be a single magic click or d rug or surgery that can fix it. 1 will also expl ain what 1 am doing to the nurse a t your work a n d 1 w i l l ring you r doctor a n d send a shor t report. Appointment 3 Ruby arrived very early for the appointment. She seemed nervous. '1 don ' t thinl< 1 need to come any­ more', she said. 'I have been thinking about it all night. For years 1 h ave been going to doctors and spe­ cia lists and therapists and I am sick of it. I rea lly only ever wanted two things. 1 wanted a good examination and 1 wanted to know that I cou ld go back and do more garden ing and more activity without harming myself. I feel I can do that now. 1 a m j ust going to slowly work into it a bit more each day. Minor aches and pains, I won't worry about but I will stop at around half an hour and then I will try and i ncrease that the next week. maybe do some digging and plant­ ing. That will nt nicely as the days are getting longer now, but I am going to gradually work into more activity, maybe even have a few hits of tennis with my children. I will ring you if 1 need you and 1 would be very grateful if you could explain this to the industrial nurse and the doctor. I will increase my time at work. Thank you very much.' 1 was very surprised. 1 thought 1 had a lot more to offer her, but 1 felt happy with her responses. 1 h a d intended t o manage her for approximately 6 weeks,

with one visit per week. I had written down my plan for management and it included the following. • Reassess physical signs i ncluding her neurological

signs. • Reassess her hoperuUy changing beliefs and thoughts

about her back, her pain and activity. • I was going to talk more about movement and the

brain, how the brain is hungry for new inputs, how i t changes with loss of normal inputs and how physical exercise is as much for the brain as it is for the body. I wanted to keep adding some inIormation each visit. • Check the need for slump mobilization and spinal exercises. Perhaps treat with some passive as we l l a s active slump mobilization. I may have mobilized or manipulated j Oint segments eventually, if I felt sure she understood where such a treatment fitted in to the big picture. • Try and c hange the maladaptive movement habits. This could begin with the new habit that she had developed to pick thinks up 0[[ the 1100r. Somehow, movements that have been learned to be pain[u l need to b e presented t o her brain i n a non-pain[ul way.

I n addition, I a m not aware of any 'authority' who would disregard the management of relevant phys­ ical impairment in acute or chronic pai n . The key is the word ·relevant' . A simple way to answer the ques­ tion of relevance of speciftc physical impairment is to ask. ' is this a physical sign that needs to be altered to make the patient function better?' In addition, some knowledge of the neurobiology of pain can help. Modern neurobiological science makes it clear that many of the physical signs that well-meaning manual therapists in the past have collected are not jus t indications of processes i n the tissue that are presumed to be tested. They are a represe ntation of tissue factors and nervous system factors. Nervous system factors include the representation and mean­ ing of that particu lar examination technique at that time and in that space. This does mean that fa lse­ positive findings must occ ur. With Ru by, my j udg­ ment would be t h at the slump responses were a combination or tissue factors and an upregu lated central nervous system. Hence u relevance j udg­ ment requires an understand ing of neurobio logy and pathobiology. This knowledge is often lacking in manual t hera py. Specitlc physical impairment does not have to be treated by specific physical techniques. Our physical techniques are j us t one tool. which in the case 01' this patient I may have employed. Specific physical impair­ ment may also improve with better understa nding. reduction of fear. touch, better general physical health. and return to activity.

D

At the star t of this case , you note that this patient was one of four from your career that 'stand out as s ignify ing changes in my understanding of clinical prese ntations and my professional direction'. Could you comment what was i t about this patient that made such an impression on you?

• Clinician's answer It was the third day when Ruby said she did not need to come back. It was a powerfu l moment as we j us t looked a t each for a period of time not saying any­ thing. I think we were experiencing similar feelings: she some form of awakening and a realisation of the meaning of pain, wh ile I was sti l l awestruck by the power of taking the messages of pain science to patients.

• Clinical reasoning commentary On completion of the patient initial examination. whether achieved i n the first appointment or over several. the manual therapist should have identi­ fied speciflc hypotheses in each of the hypothesis categories (see eh. 1 ) . Collectively, these hypothe­ ses represent the t herapist's 'diagnosis'. which includes his/her understa nding of the problem. the person. the elrects the problem are having o n the person's life. and appropriate management strategies. Huwever. except for very s traigh tfor­ ward patient problems where the clinical pattern and course or management arc not in any doubt ( i.e. no problem solving req uired) . the hypotheses reached through the examination must then be tested through the managementlreassessment process. As tbe clinician discusses here, even with a hypothesis of a dominant pathobiological cen­ tral pain mech a nism, physical impairments ( speCific or general) may still be relevant. In fact. speaking at an u npublished pain sem inar in Australia. Patrick WalJ discussed this very issue and sh a red the story of a patient whose central sensitivity and psychiatric symptoms were main­ tained by a specific physical impairment or his kid­ ney. The point here is that it can be very difficult to be cer tain in the more complex patient presenta­ tions what is necessarily relevant and whether identified physical impairments are the result or. or the trigger to. a concomitant central sensitiza tion. Hence. as discussed in Chapter 1 . the reason ing process must continue through the ongoing man­ agement. Often it is not until physical impairments have been addressed in the management. and the pat.tern of response to such management is revealed. that the therapist can reach a more secure decision. As manual thernpists. teaching is a central com­ ponent of Ollr management with most patients. While some o f our teaching is i nstrumcntal or pro­ cedural in the form of specific exercise instruction. much of our teaching centres around aSSisting patients to renecl 0 1 1 their own perspectives (e.g. beliefs and health attitudes ) ; through this self­ rel1ection and our explanations, our patients learn: that is they acquire new perspectives or u nder­ standings of their problems and their manage­ ment.

When questioned further about this weakness, David added that the weakness was related to distance and that during this most recent episode he had found it necessary to rely on crutches for ambulation. At the time of his ori1ce visit, he was not using an assistive device to aid him in walking. He also indicated that there had been episodes of bladder urgency, when he

had to rush to the bathroom on his crutches and quickly void to prevent urinary incontinence. Upon subsequent inquiry, he revealed he had never lost control over his bladder and had not experienced any burning sensations during urination. David denied having any paraesthesia or nwnbness in his extrem­ ities or groin region.

What were your initial thoughts about the pattern of onset of the symptoms, particularly regarding their episodic nature?

Clinicians' answer

Instability is characterized by exacerbation from minimal perturbation . The fact that the patient had had numerous episodes of LBP over the years caused by insignificant or no precipitating events tended to suggest a diagnosis of instability. The onset

at an early age was a lso consistent with this syn­ drome's presentation, as was the temporary help he obtained from chiropractic care. The patient's use of a supportive device (crutches) with some relief provided further support for the instability hypothesis. Finally, the patient gestured with his hands what appeared to be a lateral shift compatible with lumbar instabili ty. Conversely, the patient did not indicate he was a 'self-manipulator' , which tended to negate the hypothesis of instability, as did his gender.

The clinical diagnosis of 'instability' hHs Jccn bypo­ thesized as the cause of (or factor contributing to) the patient's symptoms. based on the recognition of typical cues associated with this dinical pattern, and probably considering the fact that this is a disor­ der with a relatively high prevalence. A second precautionary hypothesis related to potential mechanical causes o f bladder dysfunction is given less weighting, based on an absence of typically associated cues and probably considering the fact that cauda equina syndrome is a disorder that is rarely clinically encountered. Nevertheless. i t is important to note that neither hypothesis has been accepted or rejected at Ihis early stage. which would have constituted an error in the clinicians' reason­ ing, with additional testing of these hypotheses to be undertaken through further questioning and stan­ dard physical examination procedures.

answer

Not really. as it was apparent these episodes were not persistent or worsening. Upon questioning the patient further. it was clear he was not describing a spastic bladder (no feelings of constant fu llness or episodes of voiding abnormal ly small volumes of urine) nor any episodes of urinary incontinence (no dribbling as would be expected with a flaccid bladder). In addition. these episodes were not constant and ongoing. certainly not the frequent urgency one would expect from a spastic bladder. He merely had a couple of instances when he had to rush to relieve a ful l bladder and thus no further investigation was warranted at this stage.

Analysis of the i mpact of pai n David filled out a Mod ified Oswestry Questionna ire (MOQ). a 1 0-category inventory of a patient's perception of the disability they have incurred as a result of their LBP (Fairbanks et ai., 1 9 8 0; Hudson­ Cook et al.. 1 9 8 9 ) . In each of' the 10 categories, the patient is asked to select the statement that best applies to them from six possible responses that vary sligh tly in their descriptions. For example, the state­ ments in the pain intensity category range from 'The pain comes and goes and is very mild' to 'The pain i s severe a n d does not vary much ' . In addition to ques­ tions relating to pain, the categories also include questions pertaining to functional tasks. such as sit­ ting. standing and walking. Each category is then graded from 0 to 5 depending on which statement the Table 4.1 Stage

patient selects. The category scores are totalled and multiplied by two to produce a score out of 1 00'X.. Thus, the higher the percentage the more disabled the patients perceive themselves to be as a result of their back pain. David 's score was calculated to be 46%, indicating that he viewed himself as being significantly disabled when performing daily tasks. An initial MOQ score of 40-60% is one of the criteria used to assign a patient a stage I classification (Table 4 . 1 ; Delitto et ai., 1 99 5 ) . I f the initial score is extremely high (greater than 60%) and the episode is more than a few weeks old. it raises the suspicion of an affective/cognitive component to the patient's complaint. An elevated score on this ques­ tionnaire may also indicate a serious non-mechanical disease process that is not amenable to physical therapy intervention (e.g. metastatic bone d isease).

the p'atient's symptoms? Could you please discuss the supporting and negating evidence for each hypothesis.

• Clinicians'

answer

At this stage, the primary diagnostic hypothesis was that of l umbar instability. Supporting evidence for this hypothesis included : the history of multiple episodes of LBP associated with only minor or even no precipitating events • worsening of symptoms with inactivity and relief with movement over 24 hours • pain reduction fol lowing chiropractic treatment in the past but with diminishing returns. •

The sole negating evidence was the bilateral presen­ tation of the lower extremity symptoms. The main competing hypothesis was a central disc herniation. This hypothesis seemed IU<ely consider­ ing the bilateral presentation of the patient's symp­ toms. The reported worsening of symptoms with f1exed postures (sitting) was consistent with this diag­ nosis. In addition, the use of crutches to assist with ambulation seemed to indicate the profound muscle wealmess one might associate with a massive central disc herniation. The patient's positive response to methylprednisolone also supported this hypothesis. Initia lly, the report of urinary problems possibly appeared to indicate a central disc herniation, but subsequent questioning determined that the patient did not have frank bladder dysfunction. Evidence that tended to negate this hypothesis included the mechan­ ism of injury. In a healthy individual, a disc herniation would require a large amount of force, such as com­ pression through a llexed spine or a lifting injury. In this patient's case, a round of golf seemed to be insuf­ ficient to produce an injury of this magnitude. Furthermore, the patient did not report any kind of sensory disLurbance, numbness or paraesthesia, which one might expect "\lith a herniated disc compromising neural tissue.

• Clinicians'

answer

At this point, the major pathobiological pain mechan­ ism considered was nociceptive. In keeping with an initial hypothesis of instability, mechanical noci­ ceptive pain seemed probable. The inability to exercise the proper neuromuscular control over the available range of motion can result in the deformation or tis­ sues, causing pain. In addition, this mechanical noci­ ceptive pain response may lead to chronic adaptive pain and an affective component to the condition as the patient avoids activities that are known to provoke pain. The affective component to the disorder m ay result in fear-avoidance of activities that the patient suspects will exacerbate his pain. Did you consider that psychosocial factors may have been contributing to the patient's current and/or previous episodes?

• Clinicians' answer No. The patient was referred to the clinic by a ther­ apist near his home. It was this therapist's opinion that the patient's problem was not related to psychosocial issues, but that he had been misdiagnosed. In add­ ition. the patient travelled a long distance and pro­ vided h is lodging at his own expense. The patient was also self-employed , working in his family's business. He was not l itigating and no avenue of secondary gain could be identitled. He was well-educated and seemed content with his employment and socio­ economic status. During the interview, his affect, mood and responses were all appropriate. His pain diagram was appropriate in that the source of pain was most likely anatomical and the diagram did not indicate an increased level of psychological distress. The area on a p ain diagram that a patient marks can be related to their level of psychological distress (Margolis et aI., 1 98 6 ) . In this patient's case, the area marked was

relatively small and specific. Finally, it is not uncommon that patients with psychosocial issues have an ele­ vated numerical pain rating. This patient's rating was only 2 on a 1 0 point sca le.k

Clinical reasoning commentar y Despite the 1 3-year history of lumbopelvic pain and numerous health practitioners consulted. the clin­ icians have not erred in their reasoning by automat­ ically assuming that psychosocial impairments would be significant factors in the maintenance of

PHYSI C A L EXAMINAT ION

The physical examination began with an assessment of the patient's pelvic landmark symmetry via palpa­ tion and with the pelviometer (Piva et a I . , 2003), a device for measuring iliac crest level in the standing and sitting positions ( fig. 4.2). This revealed a high right iliac crest and a high right anterior su perior iliac spine ( ASIS) in comparison with the left side. The left PSIS and right PSIS were determined to be even. A standing nexion test was then performed, with the examiner palpating both PSIS while the patient Oexed forward from an upright position. With this test, a posi­ tive result occurs when one PSIS has a greater overal l excursion than its cou nterpart i n relation t o its start­ ing position. The side that has the greater excursion is regarded as being hypomobile because the il ium and sacrum have moved as a unit (instead of moving sep­ arately as per normal). The standing Oexion test was found to be positive on the right, whereas a seated Oex­ ion test was found to be positive on the left. Active lumbar Oex ion, extension and both direc­ tions of side bending were non-provocative. There

this patient's symptoms and associated activityl participation restrictions. Although, on the one hand. such impairments were obviously consid­ ered and tested for during the subj ective examina­ tion, it is clear that l ittle or no supportive evidence for a psychosocial hypothesis was thought to be present. Biased thinking. on the other hand, could have led to such an assumption bein g accepted (despite the evidence to the contrary) and inappro­ priate psychological management being imple­ mented. possibly at the expense of appropriate physical management.

was a slight deviation of the trunk to the left of mid­ line with forward bending. David was able to heel and toe walk without evidence of weakness in either the dorsiOexors or the plantarOexors in both lower extremities. Muscle strength in the remaining major muscle groups of the lower limbs was tested and found to be 5 / 5 . The knee and ankle j erks were brisk and bilaterally symmetrical. Straight leg raise (SLR) was assessed and found to be less than 70 degrees bilaterally. The end-feel suggested that the limitation was secondary to insufficient hamstring length and there was no provocation of LBP or other symptoms, as might be expected with restricted neural mobility. The FABER test (passive Oexion, abduction and external rotation of the h ip j oint) was performed as a quick screening test for the hips and reproduced anterior groin pain bilaterally. In add ition, the lateral aspect of the knee ( both left and right) failed to approximate the table when the patient was put into the FABER test pOSition. Internal rotation of the h ip j oint in neutra l (0 degrees hip Oexion in prone lying) and also i n 90 degrees hip Oexion (in sitting) was then examined passively. There was significant limitation of internal rotation motion bilaterally i n both of these positions. Provocation and accessory mobility test­ ing was performed by mobilizing from the sacrum through to T I l in a posterior to anterior direction. The vertebral joints in the thoracolumbar region were found to be generally hypomobile. A t this point a measurement of David's chest expansion was made.

A tape measure was circumferentially wrapped around the patien t' s chest at the nipple line and meas­ urements were taken at maximal exhalation a nd i nhalation. The chest expansion was fou nd to be less than 1 cm. Assessment of the passive range of motion

(PROM) for shoulder nexion revealed significant limi­ tations bilaterally. No fu rther physical examination was carried out at this stage.

R EASONING DISCUSSI ON AND CL INICAL R EASONING COMMENTARY What was your interpretation of the pelvic joint exam ination findings? How much importance did you place on the observational tests, particularly considering their reliabil ity and validity! What is the mechanism by w h i c h the ASIS was high but the PSIS was even!

• Clinicians' answer The i nterpretation of these findings was that the patient was not actually describing a lateral list, but rather a torsion of the pelvis. Normally a com­ posite of tests is used to diagnose il iosacral or sacro­ iliac jOint dysfunction . The tests used in this case were the comparison of variolls pelvic landmarks with the patient standing, and also with both the standing ilexion and seated nexion tests. All of these observa­ tional pelvic tests h ave been shown to meet an accept­ able level of rel iabi.l i ty (NIOSH. 1 9 8 8 : Piva et aI., 200 3 ) . The more of these tests that are positive (abnormal lI nding), then the more evidence there is that the patient has a pelvic obliqu ity (sacroiliac jOint dysfu nction or leg length discrepancy). Furthermore. when three out of four tests agree that there is a pelvic component to the patient's problem, the weight of the findings indicates that one can effectively and accurately intervene. A leg length inequality will cause the appearance of a high i liac crest, ASIS and PSIS on the side ipsilateral to the long leg. A concomitant posterior rotation of the inominate (fixation at the iliosacral j oint) on the same side as the long leg will cause the ipsila teral iliac crest and ASIS to appear even higher. while both PSIS may appear to be even.

What weighting did you give the previous diag­ nosis of a her niated disc? What clinical features at this stage in the examination supported and refuted this explanation!

Clinicians' answer Not much weight was given to the herniated disc diagnosis provided by the orthopaedic surgeon. A central disc her niation would be the only possible log­ ical explanation for the bilateral symptoms. NotClbly, the behaviour of the symptoms was not consistent with this diagnosis. The patient complained of n ight pain while recumbent, a finding inconsistent with a d isc herniation. Recumbency w i l l usually provide some relief from symptoms, as the spine is unloaded. In addition . the patient's constant 2/10 pain rating suggested that the symptoms were not signitkantly affected by any position or movement. A patient suf­ fering from a disc herniation will likely report radi­ ation of symptoms with sagittal plane motion: however. this patient's symptoms were generally constant (although the symptoms were sli ghtly worsened in a flexed or Sitting posture). It is also not consistent with a disc hern iation that no position was reported that afforded a ny significant relief. Usually a patient whose symptoms are caused by a disc herniation can nnd some position of comfort, or some mechanical bias to the behaviour of the symptoms. The fi ndings of negative SLR testing and myotomal examination, in add ition to pain-free and full active range of motion of the lumbar spine, also tended to. refute this hypothesis.

Did the physical examination provide any further information to suppor t or refute your p r imar y diagnostic hypothesis of lumbar i nstability?

Clinicians' answer Some further supporting evidence for the lumbar instabi lity hypothesis was provided by the presence of trunk deviation during forward bending.

However, several other findings tended to negate this hypothesis:

answer

The physical examination was ceased at this time because of an increasingly high degree of suspicion of ankylosing spondylitis. In particular, the markedly restricted chest expansion was of concern as it is a sign commonly found in patients diagnosed as having this disorder. A radiological examination was needed to help to confirm or exclude this provisional diagnosis and also to determine the extent of articular involvement (especially of the hip joints) if changes were found.

• Clinical reasoning commentary

• Clinicians' answer A reasonable degree of SuspICIOn of ankylosil1g spondylitis led to the decision to measure the patient's chest expansion. It is a clinically useful test for anky­ losing spondylitis because a measurement of less than 2 . 5 cm is 94% specific for (or likely to rule in) ankylosiug spondylitis. If a patient tests positive to a test with a high specificity, it is probable he has the disease (Sackett et aI., 1 9 9 7) . Therefore, chest expan­ sion greater than 2 . 5 cm would be required for a normal test result (Rigby and Wood, 1 9 9 3 ) . The find­ ings that raised the suspicion of ankylosing spondyl­ itis were: reported morning stiffness, alleviated by movement constant 2 1 1 0 pain rating over a 2 4-hour period, relatively uninl1uenced by movement • some movement was helpful, but vigorous move­ ment (e.g. yoga) worsened the symptoms • bilateral h ip involvement (marked decrease in bilateral hip passive range of motion , positive FABER test for decreased motion and bilateral limi­ tation of SLR) • reduced vertebral mobility throughout the lumbar spine and thoracolumbar j u nction.

F u rther investigations David was then referred for radiological investigation. The specilk views requested were anteroposterior and lateral views of the lumbar spine, oblique sacro­ iliac jOint views, and an erect anteroposterior view of the pelvis including the hip joints. This series was

What led the clinicians to test specifically for anky­ losing spondylitis. particularly considering t hat this condition is relatively uncommon and the patient had been previously examined by many other health practitioners (including medical special­ ists)? It would appear that the inability to ' n l ' sa t is­ ractorily the various clinical Ilndings to t he more obvious mechanical diagnostic hypotheses (e.g. lumbar instability, disc herniation, pelvic jOint impairment) led the clinicians to consider or 'sus­ pect' other less frequent disorders in an attempt to explain the patient's perplexing presentation bet­ ter. Although ankylosing spondylitis was not men­ tioned earlier in the clinical examination process as a potential mechanism/source for the symptoms. it had not been excluded either. That is, the hypothe­ sis of ankylosing spondylitis probably rose through the ranks of hypotheses as the h igher-ranked pat­ terns/hypotheses initially generated failed to with­ stand testing. The clinicians have maintained an open mind and critical outlook during the exami­ nation. resisting the temptation and avoiding the reasoning error of accepting an hypothesis that may be more prevalent or favoured but which only partially explains all the clinical I1ndings. ordered based on a high index of suspicion of anky­ losing spondylitis.

in the low thoracic region and at the base of her neck, and she frequently gets headaches. Lara came 2 00 miles to see me. She was recom­ mended to me by two physiotherapists who had been working with her. She was p leasant on the phone and

said that she was desperate. I inter viewed, examined and began her management in two sessions spread over 2 days. The first session, which was entirely interview, took 2 hours, while the second lasted about 1.5 hours.

REASONING DIS CUSSION AND CLINICAL REASONING COMMENTARY

II

You decided to spend the full 2 hours of your first appointment entirely on interviewing this lady; this clearly indicates the importance you place on this initial session and on the information you will obtain. Could you briefly outline the broad aims of your initial interview and how you use this information to guide your subsequent physical examination and management.

• Clinician's

answer

There is no doubt that complex long-standing problems take time to understand fully. The broader more bio­ psychosocial approach that is taken here requires a full appreciation of patients' problems and the way in which their problems have affected them and those around them. Interview, and discussion during interview. is also a very powerful and important part of the management process. It provides the information base that clictat�s the best direction in which to proceed and it reassures the patient that I understand the problems that they are facing, as well as the nature of the presentation, There were several key aspects to the initial interview. • To find out about her situation now compared with

how il' had been before the problem started. In par­ ticular, to find ou t how much she does physically in comparison to the situation previously. This gives an understanding of her disability level and some idea of shorter and longer-term goals. • To find out what she feels is wrong, what the pain means to her, and what she feels about the future. • I also needed to find out about her expectations of me and what she was expecting from our sessions. Much insight is gained here with discussion of pre­ vious treatments and investigations, treatment effectiveness, and how messages and information given have been interpreted. • I needed to feel comfortable that no serious condi­ tion was present that would be more appropriately managed within or alongside some form of medical

intervention. Information here may lead to appro­ priate physical testing later. • I wanted to get enough information so that together we would be able to plan a way forward. • I needed enough information about her symptoms to be able to understand her problem in terms

of pain mechanisms and all the current physical and any 'emotional/cognitive/psychological' issues relating to the problem. • It is necessary to have a full appreciation of all psycho­ social factors that may impede management. With respect t o your aim to ensure that no serious con.dition was present, were you concerned/worried at this stage that her bilateral lower limb symptoms could reflect spinal cord involvement?

• Clinician's answer Not really, although it is always a possibility and should always be entertained in every patient. Important 'spe­ cial questions' and physical/neurological tests should never be left out. however confident one feels. The rea­ son for my confidence here is threefold. First. patients with chronic pain l ike Lara have usually been seen by many doctors and specialists and have often been thoroughly biomeclically screened already.' Secondly, if there was signillcant spinal cord involvement, clues should be picked up during history taking. Thirdly, bilateral lower limb pain is not uncommon in many chronic pain states and may be a reflection or central proceSSing/central mechanism factors rather than gross or franl< cord pathology.

slightly less, but 1 was getting worried and it was starting to really trouble me at night.' 4. Lara was advised to see a local chiropractor by a close friend. She was diagnosed as having four major contributory problems. These were described as facial distortion ( 'some sort of jaw distortion'), C2 fixed in a left rotated position, unequal leg and arm lengths and what the chiropractor described as the worst sacroiliac (SI) blocking he had ever seen. 1 asked Lara how she had felt about that? She said. 'I remember feeling pleased to start with, that he had found something, he seemed very confident that it would all be put right very easily. Later on 1 started to dread going. when 1 think about it now 1 felt that he started to make me feel that the lack of progress was my fault. 1 also started to worry that the things he said were wrong, were impossi­ ble to overcome. By the end I got worse and stopped going.' Treatment involved a series of regular but very quick adjustments to her head and neck and some 'pressing on the roof of her mouth ' . Lara was warned t o stop a l l swimming s o as not to upset her SI jOint: 'He told me to stop the physio­ therapy exercises and concentrate on my neck posture.' 5. A further 4 months later, Lara's doctor referred her to an orthopaedic consultant after radiographs revealed modest degenerative changes. 'He said that I had normal wear and tear on the X-rays but there was the possibility of spinal stenosis. 1 had a scan that revealed moderate disc bulging at L5-S1 and no signilicant stenosis.' What happened from there? Lara said, 'I remember feeling very empty, very tear­ [ul and almost embarrassed to start with. He made me feel as if I was making it up, I remember the com­ ment he made, "you've got the same back as every­ one else of your age on this earth", and then he said, "the best thing you can do is 100 sit ups a day and go swimming". About a week later, 1 started to feel very angry that! hadn't been believed, but even my hus­ band seemed to side with his view-when he came in from work his fIrst words were usually, "have you done your sit-ups?".' 6. Through the next few months, Lara's doctor treated her for mild depressive disorder with amitriptyUne (tricyclic antidepressant). She was also given 'pain­ kiUers' (ibuprofen: non-steroidal anti-inllammatory agent) and co-proxamol (dextropropoxyphene hydrochloride plus paracetamol: compound opiate analgesic).

from stiffness in the back o[ the thighs on bending. She also had low back pain. buttock pain and lumbar stiffness. In desperation, she returned to her physiotherapist, who concentrated on the disc bulge. She had eight tTaction treatments, which helped to start with, but pain soon returned. In addition, she was given a corset to wear all the time. Lara could not remember any exercises being given that were not stopped because of exacerba­ tion of the pain. She returned to the chiropractor. who 'cracked' her neck and adjusted her SI joint. After four treatments and progressively worsening pain, the chiropractor referred her back to her GP, who organized an appointment with the local rheumatologist. Lara saw the rheumatologist 2 months later. By now she was only waUdng around the house, rarely went out of doors and had stopped all social engagements. Her doctor son was keen for her to see a psychiatrist. 'I was starting to think that I had something that no one else in the world had ever experienced, and that because it was so new and nothing could be found to reasonably explain it, the only rational way for doctors to see me was in terms of some kind of madness! Even my son was seeing me as a mental case. The rheumatolo­ gist said that I was "atypical" and that I did not have any j Oint rheumatism. He actually took me seriously. listened and arranged for some blood tests. Once the results came through negative, he referred me to the local pain clinic. Here, I was given acupuncture and TENS (transcutaneous electrical nerve stimulation). After three treat­ ments, I had terrible pains in the balls of my feet, which the physiotherapist said was a good thing! But the pains got worse and worse and she then referred me to hydrotherapy. She said that I had tight nerves that need moving and stretching.' The hydrotherapy was the first step towards some improvement; Lara enjoyed the movement in the pool and the pain was masked by the warmth . She said she felt very safe moving in the pool and after 4-5 weeks found that she was able to do some simple back exercises lying down at home. She made further gains using the Alexander tech­ nique (Barlow. 1981). She continued through early the following year 'managing' reasonably well and even getting to

about 70% of normal for several months. Lara contlnued with physiotherapy and the Alexaoder technique. Physiotherapy she described as 'lying on my tummy for 20 minutes while she loosened me. then some stretches to my legs and ultrasound on my feet. I had four major exercises. Tightening my stomach for 5 seconds ten times three times a day. then the same but also tightening my buttocks at the same time. holding this tension and arching and flattening my back 1 cm while I was sitting. and then lying on the noor and stretchillg my leg up the door frame. The main message was that my back was unstable and that muscle tone had to be

increased to prevent it slipping out of place. I was also instructed to never bend without tightening my stomach.' 12. Five months later Lara suffered a severe setback in pain and also had treatment for depression again. 13. Lara was referred to a neurosurgeon 2 months later. who offered to do a sympathectomy. Her comment was: 'How can I go ahead with an oper­ ation when the man I saw didn't even examine me. peered at my notes. scans and X-rays. asked two questions about my cold feet and said that my only chance was to have an operation that cut nerves to improve my leg circulation?'

REASONING DISCUSSION AND CLINICAL REASONING COMMENTARY

o

What were your thoughts regarding the history of Lara's problems! Include your thoughts on the previous management.

• Clinician's answer If you really follow what happened over time. it is an unfolding story of disastrous management that sequentially reinforced the notion of structural weak­ ness and abnormality and fear of further damage; this resulted in progressive disability with psychological distress and depressive symptoms. All practitioners have been very structurally based in their thinking and have made no attempt to understand or take on board the patient's thoughts. beliefs. attributions and feelings regarding the nature of the problem. Little has been done to allay Lara's fears and rehabilitate her back to a fuller potential with increased physical confi­ dence. Therapists appeared satisfied that pam relief was an adequate outcome. Also, common to many similar patients. doctors dismissed the problem as triv­ ial and inferred mental wealmess on the patient's part. with the unhelpful end result being the conclusion that the patient has a psychiatric disorder. It is worth noting that the therapists/doctors who have lTeated Lara to date have created: • an obsession with upright posture: partially respon­

sible for creating unrealistic avoidance and struc­ tural fear. or behaviour patterns caused by the fear created by therapy • fear avoidance beliefs and behaviour. created dis­ ability/loss of confidence; this is the result of most

therapists using a 'wealc!vulnerable structure' focus and not helping the patient actively and gradually to restore confidence in spinal movement and back strength alongside their treatments • an unnatural overfocus on the body during move­ ments; instructions like 'never to bend without tightening the stomach' reinforces structural weak­ ness perception. movement avoidance, and tension with movement. Normal movement should even­ tually be trained to be thoughtless movement but pain-focused treatment reinforces a 'back off ' move­ ment strategy • confusion and conOicting information: doctors and other clinicians have been adopting a blinkered view of the problem specific to their area of interest. Specifically please comment on the key activity/participation restrictions and associated impairments you hypothesized would need to be addressed and the dominant pathobiological pain mechanism pattern you felt was emerging.

In the 'psychological/mental' impairments hypothesis category. it is clear that Lara is upset. unhappy. dis­ tressed. frustrated, and possibly even angry. There are also many very unhelpful beliefs aod attributions about structure and cause that will need to be add.ressed and overcome before a gradual functional improvement approach can be started (especially those relating to bending). A thorough examination and careful explanation of pain mechanisms would be a useful start in the process. Highlighting structural

integrity and soundness following examination would be important. It is likely that Lara will have altered movement patterns and significant apprehension pedorming many movements. A great deal of tissue testing is likely to find widespread abnormality. In particular. lumbar Ilexion and lumbar Ilexion activi­ ties may need careful addressing. It would be unwise to try and be specinc about the pain mechain sm(s) consequent neuroplastic changes in nervous system input, processing and output pathways/networks. the weak and deconditioned tissues. possible minor or moderate degeneration. lack of normal movement patterns and the psychological and social consequences of the whole episode. A single lesion approach to well­ established cbronic pain states like this one has to be. at best. extremely cautious. A broader biopsychosocial model that incorporates multidimensional and multi­ level thinking for assessment and management is prob­ ably the most desirable option (Gifford. 2000a. 2001. 2002a; Main and Spans wick. 2000; Waddell. 1998). Importantly. this does not preclude focussing on spe­ cinc physical impairments at some time in the manage­ ment process. Allocating a specific pain mechanism in this type of patient is probably detrimental in that it makes thoughts linger in a focussed way and misses a far big­ ger picture. A sbift in focus to disability (Le. activity and participation restriction) management is probably the Singularly most important issue. Clearly though, altered. or maladaptive, central processing of sensory and motor information, central generation of pain. maintained peripheral sensitivity, peripheral nerve hypersensitivity and all output mechanisms have a role in presentations of this type. The message is that there is no specific single source targetable by passive therapy interventions. By working on the patient's

thoughts and beliefs. alongside graded return of phys­ ical function and confidence, we will actually be work­ ing and manipulating neural pathways responsible for the pain and disability problem (Gifford, 2000b). A key thought is that inputs that improve things like self­ emcacy. patient sense of control and understanding. levels of distress, physical function and goal achieve­ ment will have positive neuroplastic effects that will have repercussions for the health of the whole organ­ ism (see Gifford. 2002b; Lawes. 2002; Roche. 2002).

Lara flfst saw me the following month. The follow­ ing summarizes the current situation and other perti­ nent information to her condition.

Family history

Father fine, mother diagnosed as having spinal stenosis in last 2 years (86 years old). Mother always grumbled about her back and never did any Ufting. She also never did any walking or kept fit. Lara has a brother 63 years old. very inactive with a long-standing bad back.

Cli n i cal reasoning commentary

A key aspect of experl reasoning we wish to draw readers' attenlion 10 here is the clear iIIuslration of the c1inician's thinking occurring on multiple levels. Recognizing apparent psychological compo­ nents. activil-y restriclions anc! physical impair­ ments within a broader picture of overlapping pain mecbanisms has provided a basis on which man­ agemenl strategies are already heing formulaled. Despite the emerging pattern. Ihe patient's prob­ lem has not been pigeon-holed into a scenario where the pain and phYSical impairmenl arc seen to be completely driven by the psychosocial issues. Rather. management of speciJic physical impair­ ments is hypothesizeo as possibly being required. and the facilitation of 'thoughtless' normal move­ ment. consistent with motor control retraining philosophies featured in other cases in this book. is Seen as importanl in the ovemll management. Also note here. and throughout the case. the clin­ iciun uses quot<Jtions from the patient extensively. This reflects how much he listens Lo the patient and the importance he places on the patient's thoughts and feelings ahout their problems.

Lara is constantly aware of symptoms (Fig. 5.1). These rate on the Numerical Rating Scale (NRS) as 8-9 on average; 6 at best and 10+ at worst. The main prob­ lem is with the feet and back. Symptoms are described as burning. stinging. Ilickers. tightness or compres­ sion feeling. and cold discomfort. Lara describes being able to hear her feet grating and has the feeling that something inside was stuck and would not move. She describes her feet as having burning pajn yet feeling

Any form of concentration has made the problem worse and makes her very frustrated and upset. When asked why she had stopped so much, Lara said that she had a fear of doing more damage, creating more pain, and of something giving or going, with days of resting afterwards. She said she felt weak; activities made her limbs feel heavy and she got very tired very easily.

REASONING DISCUSSION AND CLINICAL REASONING COMMENTARY

o

There is a certain degree of stimulus-response predictability that is apparent in the behaviour of her symptoms. In your previous answers, you noted that you felt there was strong evidence emerging supporting a dominant processing pain mechanism in her presentation; however, elsewhere (Gifford and Butler, 1997) you have described a common feature of the nociceptive pain mechanism pattern is its stimulus-response predictability. Can you comment on what features of this lady's presentation alter the

keeping with the extent of tissue pathology) are the length of time the problem has been around, the severity and reactivity of the symptoms, and the lack oj' medical evidence for significant enough pathology. One would expect less reactivity perhaps from a severe rheumatoid arthritis presentation. It might be best to reason that Lara has a great deal of maladaptive noci­ ception going on and maladaptive processing of noci­ ceptive traffic in the central nervous system as well. Clinically this equates to too much pain and sensitivity for the state of the tissues: hurt does not mean harm.

mechanisms or sources!

A degree of predictability in symptom response to mechanical stress is common to a great many pain states: it is just as easy to increase and decrease symp­ toms instantaneously using physical forces and move­ ments in an acute injury as it is in chronic pain states. 'Processing', along with cognitive, emotional and behavioural responses, are still a feature of all pain, even presentations that are acute and deemed largely nociceptive in nature. However, in the more chronic state, inputs that produce a pain response may be coming from quite normal tissues as well as from tis­ sues that are in various states of 'iLI-health'-many of which presumably contain maladaptively sensitized and hence over-reactive nociceptors. Further, and central to chronic pain states, is the fact that the pain 'reaction' to physical inputs is often way out of propor­ tion to what might be 'needed' by the tissues. In Lara's case, features that tend to discourage any thoughts with regard to major nociceptive mechanisms (for which the stimulus-response pattern is more in

Clin ician's answer

Not really. There are some features that might elicit thoughts relating to circulation or even aberrant sympathetic activity: like the cold feet/legs and skin colour changes. Hence, one line of thought could be: maladaptive central processing leads to altered and inappropriate outputs, which, in turn, lead to sensory inputs and more sensations. Another side of the issue is that symptoms lU<e alterations in temperature and blotchy skin may well represent reactions of a very unfit and deconditioned body and are hardly surpris­ ing. Also, there is the likelihood that Lara's attention system has become conditioned to focus on bodily sensations, thus changes in temperature may be going on normally but, as a result of the maladaptive bias in attention towards her soma, she has become greatly aware of them. These types of interpretation are 'bet­ ter for the patient' because the message that comes . across is that improved function and fitness, decreased

Dangers come when clinicians see an altered muscle control finding as key or central to this kind of problem. This is just a small hypothesis with regard to the 'bio'

Some features of her presentation, such as her coping best in the morning, frequent sharp jabs of pain and even her preference for walking fast, could be interpreted as support for a 'postural' or muscle control problem. Do you feel this impairment could be a component of her problem, either as a possible predisposing factor to the original onset and/or as a contributing factor to the maintenance of her symptoms? Could any 'motor control' impairment that may be present be a manifestation of her altered input-output mechanisms, that is a learned phenomenon with implications as to whether and how this should be addressed in her management?

part of the assessment and needs to be attached very strongly to the 'psychosocial' part. I would be very wary of overfocussing on specific 'muscle control' issues in the early stages of patients like Lara. You ask about thoughts regarding a learnt response. The answer is very much so. Pain alters movement pat­ terns, so does fear of injury and fear of pain and loss of physical confidence. For most patients with chronic pain, these are long-standing features that result in chronically altered movement patterns, which become 'set' as new habits and for many start to feel normal. The secondary consequences to all the musculoskeletal tissues and the circuitry of movement must be vast. Thoughts like this highlight the need for reduction of fear of movement and structural wealmess, and the adoption of adequate but graduated normal functional movement patterns Crom early on. Clearly for Lara, an

P hysical examination has signillcance for the manage­ ment process. fo r diagnosis and for the patient. For the pa tient. we need to seek to reassure via a thorough examination. The patient must feel that a thorough exami nation has been done and that any findings have been given a reasonable explanation. It is wise always to attempt to give reassw'ing messages. rather than cre­ ate fear. Examination is perhaps one of the most import­ ant parts or t he management process: an important issue fo r patients l ike Lara is finding features that are good and highl i ghting them as they emerge. rather than searching out the bad and adrung to the worry and confusion. For manage ment we need to explore the extent o f physi ca l impa irment and make sense of i t in relation to the type of intervention offered.

Lara has had plenty of medical screening tests and is. therefore. unlikely to have any serious disease process. Examining patients like Lara. who have chronic pain and marked activity restriction. does not normally warrant any in-depth or focussed appraisal of mi nor impairments if a broad educational/self-management/ functiona l recovery approach is to be adopted.

Clinical reasoning commentary As discussed above. it is casy to overattend to the sou rce of the symptoms i n a classic medical diagnos­ tic sense. While hypothesizing regarding symptom source is lIseful in many patient pre sentations. and here the clinician is i ncreasi ngly more certai n or a ""idely distr ibuted source to much of her symptoms. identifying the contributing factors relevant to the presenting disability often will be as i mportant. or even more important. to a successful o utcome. [n this case. psychosocial factors/impakments are con­ sidered the key contributing factors. although phys­ ical impairments. such a s the altered motor control discussed above. may also be seen as contributing factors to the maintena nce of her problems. While experience will enable therapists to recognize pat­ terns where physical i mpairment is secondary to the broader psychosocial and health/fitness concerns. as is t he case with this patient. prematurely di s­ counting or not e ven a ssessing for physical impair­ ment is a s much an error as only looking for specific phys ical impa irments \·vithout regard for the broader psyc hosocia l and health status of the patient.

Before moving, on I did an additional two tests: axial loading and simulated rotation. Both these tests are used to indicate what Waddell terms 'behavioural signs'. These signs and the reasoning behind them are described in detail in his book The Back Pain Revolution (Waddell . 1 9 9 8). This book is strongly recommended to all manual therapists. Axial load­ ing involves slight pressure applied to the top of the patient's head with your hands. Simulated rotation aims to rotate the patient's body without prodUCing rotation in the lower spine. In order to do this, the examiner gently rotates the patient from the pelvis making sure the trunk does not twist. Trunk twist can be prevented by getting the patient to stand relaxed with their hands at their sides, holding the patient's wrists or hands against his or her pelvis, and passively directing rotation of the body. Both the tests were posi­ tive in that they provoked pain in the back. The other 'Waddell signs' are: • widespread tenderness spreading far beyond single

anatomical regions and often over many segments • distracted straight leg raise (SLR) • regional weakness indicated by weakness over many segments and a jerky or 'giving way' response: for example, weak and j erky quadriceps testing, yet the patient can walk • regional sensory change: losses of sensation where the boundaries are beyond the normal innervation field and dermatome distribution. The symptoms may include: • pain at the tip of the tailbone • whole leg pain

I now asked Lara to sit on a low stool. I sat i n front of her. again doing the movements with her. Movements performed were head into flexion and back up, and slumping the spine. As I did the latter movement I said, 'Can you let yourself go into what I call lazy sitting, like this?' She commented back, 'I haven't done that lor 2 years-I've been told to keep upright to stop the disc bulging'. Remember that her bending was 10 degrees in standing and that her husband had helped her undress-1 had not seen her bend beyond this. I then hugged one knee to my chest and gently dropped my chin part way to my knee: 'What about this movement, or a part of it?' Lara tried and demonstrated quite smooth movement with spontaneous lumbar flexion using either leg. Importantly, I did not say something like: 'See your back is bending ' . All I said was, 'That looks good, now lets try this'. I put my leg back down, placed my hands on my knees and slowly lowered my body forwards towards my knees, saying, 'See what you can do. You have your arms to stop the movement if you are not sure and you can come back up any time you m(e. If you don ' t want to do it. that's nne.' She flexed very slowly but quite well in the spine and hips, probably about half normal range. I then looked at Lara's feet, palpated them generally and did foot movements and muscle tests while she sat with her legs dependent on the treatment couch. Her feet were cold and 'blotchy'. They were hypersensitive to palpation, particularly over the balls of her feet, but active movements were good. AU muscle tests produced giving way (a notable 'Waddell sign'). Her feet looked anatomically normal. with no evidence of swelling or degenerative changes except some slight lipping of the medial joint line of the metatarsophalangeal joint of

the big toe. Lara mentioned being aware or some crack­ ing and clicking in the ankle joint. My response was. 'Is that concerning you?' She replied. · It makes me feel that arthritis is setting in'. I responded. ·OK. that is an issue that I will put on my list of things to go inLo'. The pOint is that until a patient understands the nature of chronic pain and tissue health issues it is difficult and often unhelpful to discuss individual concerns like this. The best strategy is to listen and acknowledge all the patient's worries and concerns so that they can all be dealt with later on. Calf and quadriceps rel1exes done in this sitting pOSition were quite normal. There was no clonus and the Babinski test was normal. Proprioceptive testing in all lour limbs was normal. There was no major sensory loss to light touch. although diffuse areas of slight nu mbness around the (oot and lower leg were revealed. The key words she Llsed were. 'I know its not as it should be'.

Lying examination

The examination continued in a similar vein in supine lying. crook lying and side lying. Most tests were actively perJormed by the patient and directed or demonstrated by myself. For example. Lara performed the following active movements in lying. • Hip flexion: patient grabs her knee and pulls it

towards her. Lara was very tentative but could do it. • Active SLR: good range to 90 degrees with the oppos­

ite leg in 'crook' position. With both legs straight she could not initiate the movement. Passive testing/ assistance revealed marked pulling in the whole leg at 70 degrees ( both legs). If active dorsiflexion was then added, the pulling spread into the foot quite markedly. Active lumbar rotation in crook lying "vaS half range and tense. Active hip abduction in crook lying position demon­ strated good range. Active pelvic rocking surprisingly showed a good range of llexion, well coordinated and with no wincing! Extension was of modest range and rea­ sonably relaxed until pain came in. Leg length looked quite normal with reet together in supine and crook lying (she agreed) .

not. patients are more likely to listen to and believe clinicians who in their minds have some kind of higb professional status. The second aim was to help Lara to understand that a passive treatment approach was inappropriate at this stage and that the best approach involved a great deal of input from her. Part of this involves a shift in emphasis from pain-focussed management to more function-focussed goal achievement. Education. therefore, involved a simple brief discus­ sion of the following. The nature of adaptive/acute pain and chronic/ maladaptive pain: the former is useful , helpful pain as opposed to useless. unhelpful pain. • A simple explanation was given for maladaptive and excessive sensitivity to movement, intolerance of prolonged posture, and tenderness/hypersensi­ tivity to touch and pressures. • The analogy was made of ongoing background pain to an annoying tune in the head all the time. i.e. the constant pain relating to abnormal nervous system 'circuitry activity ' rather than a disease or abnormality in the tissue where the hurt is felt. Explaining and discussing phantom limb pain often helps here (Gifford 1 998a. b). • The gate control theory of pain is explained (i.e. that pain normally comes and goes relative to an individual's attention and the value or meaning they may put on it). •

The effect of mood on pain, activity and life in gen­ eral is discussed. This helps the patient to come to terms with low mood being normal for anyone who suffers an ongoing and seemingly non-resolvable problem. It also underlines the positive message that mood state commonly improves as the patient starts to achieve progress and gradually recover better physical function. • The effect of 'pain fear' and 'damage fear' on move­ ments, activity and life leads on to introducing a treahnent approach with a locus more on functional recovery/physical confidence rather than on getting rid of the pain or the apparent source of the pain. Patients somehow have to come to terms with the fact that pain therapies and medical interventions for chronic ongoing maladaptive pain have a very poor record of success. In contrast, approaches that focus on better physical confidence and fitness have a much belter record. ft is sometimes helpful to give a brief history of another palient who bas been successful. Giving the patient a book like Neville Shone's Coping Successfully with Pain ( 1 995) is often very helpful. • The illustration from Nicholas ( 1 996; Fig. 5. 2) was used to show the patient the way in which modern pain research has begun to appreciate the com. pJexity and difficulties that a patient with ongoing pain can have. Patients are often relieved to find that medicine is beginning to understand the impact that their ongoing pain has on their lives. and that they are not alone.

Lil<.e many si milar patients. Lara fou nd the inlormation very enlightening and interesting. She had many ques­ tions. and we both explored many issues that related to the hopes and lears of past management as well as issues for the fu ture. She quickly grasped the concept of maladaptive pain and that physically getting back more relaxed and normal movements would be a good start­ ing point for recovery. She was insta ntly eager to start the physical 'chaJ lenge' and we spent q u i te some time dealing with fear of bendinglnexing the spine and the natural stTCngth of the spine. even when degenerate. As with so many patients in s imilar situations she said. 'Why hasn't anyone told me th i s before about pain and movements?' An answer that can helpfully be given is that. ' I l is o n ly in the last 1 0 to J 5 years or so that science and research has started to give us a better understa nding or pa in. and it is only very recen t ly that the fu ll implications for management of pain has started to have an impact on clinica l practices'. This attempts to avoid producing any unhelpful anger with previous practitioners and treatments or advice. Pre-prepared handouts were given relating to all the above.

Baselines, pacing and incrementing Most pain sufferers like Lara persist with activities until they are forced to stop by the pain. This often i nvolves many hours. sometimes days of resting and i nactivity. In order to breal( this overactivity-underactiv ity cycle, exercises and activities are paced so that this very u nproductive p rocess is overcome. A base l ine is the number/repetitions/amount of time for an exercise or activity that a patient can manage to do every day regardless of the intenSity of the pain. This is found by taldng the average of a series of trials done over several days and then reducing the average by 2 0%. Incrementing or pacing from this baseline is done by increasing the number or time of each activity / exercise after a set period. for example weekly or every fou r days (Harding, 1 9 9 7 , 1 9 9 H : Shorland. 1 Y 9 X ) . The overactivity-underactivily cycle was explained and pacing o f resti ng was d iscussed. Exercises were recorded for reference and handouts were given relating to exercise and functional pacing and the overac tivity­ underactivit')' cycle.

Clinician's answer Lara has successful ly coped with a new perspective on her problem for over a year. She has made quite sig­ nificant gains in function and independence and has reintroduced many of her former hobbies and inter­ ests. This was a l l he lped by her open-mindedness. her readiness to accept new perspectives on her problem, and her eagerness to take responsibility for her own management. Her home situation and fi nancial secu­ rity were very helpful in that they a ll owed her to h ave time to devote to the programme. She got involved, she did the programme and she worked hard at i t . Note h e r comment above that ' worki ng w i t h chronic pain can be very hard work ' .

Lara is as vulnerable to relapse as aoyone and this is a strong possibil ity. Her long-term prognosis looks good. Importantly, there are two aspects to consider for the future: her dis­ ability and fu nction and her pain and symptoms. The prognosis for fu nction is good.

She moved in a relaxed way and was not frightened to bend her back. She could easily bend to touch the floor with both hands nat: she could walk happily on tip-toes and go up stairs two steps at a time. She sti l l had low periods and occasional pain Ilare-ups. Her pain level overa l l was. in her words. 'more manageable and less intrusive ' . She slept much better and man aged slowly to stop a l l her medication. She commented: ' Worki ng with chronic pain can be very hard work. it is a daily cha llenge that most o ften is quite conquerable, b u t on some days it is a long and very tough and tiring struggle ' . At the time o f writing, there h a d been seven visits in total and s he was coming to see me about once every 3-4 months. There had been no passive treat­ ment, but there had been a great deal of s k i lled phys­ ical appraisal and the gradual i n troduction of more and more specil'ic exercises related to more minor physical impairments.

in this case.

In this case, the postural assessment revealed no significant difference between the left and right upper limb , which may indicate that the variance in posture was not directly related to the pain disorder. However, the abnormal posture and possible related muscle dysfunction may have been a contributing factor to the problem. Lee (1986) has postulated that the type of head and neck posture seen in this patient may be a

precipitating factor in the development of chronic

tennis elbow. and that correction of this posture is an important aspect of treatment. The history of neck problems, abnormal bone scan findings in the lower cervical and thoracic spine. and the abnormal cervi­ cal and thoracic posture indicate the need to examine the cervical spine thoroughly. If the cervical spine was found to be a significant contributing factor to the problem. then the abnormal posture may need to be addressed. In addition, the flexed and pronated forearm posture may have been caused by muscle imbalance or joint restriction in the elbow complex, necessitating assessment of both muscle and articu­ lar function.

At this stage, were there any potential contributing factors (e.g. environmental. biomechanical) identified in either the subjective or physical examination that you considered may be relevant to the development or maintenance of his problem?

• Clinicians' answer Tennis elbow is not restricted to those that play tennis and other racquet sports (Kivi. 1982). It is common in the general non-sporting popUlation, especially amongst those whose occupations involve repetitive or forceful forearm, wrist and hand activities (Plancher et al.. 1996). particularly involving overuse of gripping and wrist extension. Following an extensive survey of 15000 residents of Stockholm. Allander (1974) reported an annual incidence rate for lateral epi­ condylitis of 0.1- H{, and a prevalence rate of 1-10'1'0. A number of factors can be identified from the subjective examination that may have contributed

What were your initial thoughts at this stage? In particular, what hypotheses were you considering with respect to the source of the symptoms/ impairments and the pain mechanisms involved?

resulting in repetitive irritation of spinal structures. Regardless, it would be important to consider cha n ges in the central nervous system perception and inter­ pretation of pain.

D

Did you consider that there were any significant psychosocial factors in the patient'S

My initial impr ession of this patient was that the coc­ cyx was probably not the primary source of her symp­ toms. This was largely based on th e fact th at there was no provocative episode related to the onset of her symptoms and that most of the painful positions and

• Clinician's answer

movements would be unlikely to impact on the sacro­ coccygeal area. In particular. the failure of the coc­ cygectomy to alter the pain suggested that it was probably not the source. There were several other options that required consideration. The location of the pain was consistent with possible somatic referral from the lumbar spine or sacroiliac joints. In addition. it was anticipated that the function of the deep trunk muscles may be compromised as a result of the pres­ ence of pain. This was hypothesized because research evidence has indicated that such a change is a rela­ tively constant finding in people w ith low back pain (at least of insidious onset) (Hodges and Richardson , 1996) and these changes can be induced by experi­ mental pain (Hodges et aI., 200la). On the basis of the mechanisms that increased and decreased her symp­ toms (such as sustained nexion) and the insidious onset of her pain, it may be reasonable to suspect disc pathology, but this is difficult to conHrm. Because of the 6-month duration of her symp­ toms, Skye had moved into a chronic pain state and as such it was likely that peripheral sources of her symp­ toms may be reduced and central pain processes are now involved. Several factors further complicated this issue. such as her depression , catastrophizing beliefs and the reduction of her leisure activities as a result of pain. However, local processes could not be excluded. particularly if the maintenance of her pain was caused by movement dysfunction/impairment,

There were several potential psychological factors that may have inl1uenced Skye's presentation. The major factor was a feeling of loss of control and uncertainty. This was compounded by the failure of the initial sur­ gery, which had promised a simple solution. Skye was also fearful for her future and had belieL, regarding the probable course of her symptoms (e.g. 'end up in a wheelchair'). She was also depressed that her social interaction and opportunity to travel were limited by the presence of pain. There is considerable evidence in the literature to suggest that mood and emotion have a significant effect on pain perception (Weisenberg et aI., 1998; Zelman et aI., 1991). Therefore. it was con­ sidered important to attempt to deal with these changes both directly and indirectly. It was planned to use t hree main strategies to deal with the psychosocial issues. The IIrst was to provide adequate education about the nature of low back pain and changes that arise when pain becomes chronic. Related discussion would also be needed to deal with expectations and misconceptions. The second was to give her back control of her situation and make her responsible for her recovery. Tal<ing an active approach to management (predominantly involVing exercise of the trunk muscles and restoration of trunk control) was considered essential for this to occur. Finally, it was planned to assist with the resolution of these fac­ tors by listening, providing support and encourage­ ment, and answering her questions.

mid -range positions and lack of frank traum a , Skye is likely to fall i n to the latter group. This theoretical construct has derived some d irect su ppor t from bio­ mech anical models of the spine. Several authors have argued that an operational deep muscle system is esse n tial for main tenance of suppor t of the spine (Cholewicki et aI . , 1 9 9 7 : Gardner-Morse et al.. 1 9 9 5 ) . O n this basis, i t seems feasi ble that one factor con­ tributing to the perpetuation of (and perhaps even causing) Skye 's symptoms m ay be the poor contro l of spinal stability. Although we cannot (yet ) directly measure in the clin ical setting the fu nc tion of TA and multi fi d u s i n stabilizing the spine, we can ga i n some indirect indi cation of function/ dysfu nction via the hollowing test wi th the pressure cuff placed under th e abd ome n . T here is initial evidence that the abi lity to perform this test is related to the tim i ng of TA in a task that challenges postu ral con trol (Hodges et a t . . 1 9 9 6) .

• Clinician 's an swer The main features of Skye's pain that were suggestive of cen tral sensitization were that the pa i n had out­ lasted tissue healing time, it was sometimes unpre­ dictable, pain and relief from treatment were laten t , a n d the pain was associated with anxiety and depres­ sio n . The ev idence from S kye's presen tation tha t was inconsistent with this proposa l was the strong correl­ ation between physical signs and her pain. For instance, it was possible to reprod uce her symptoms by perform­ ance of a simple physica l test . Many other factors of her presentation (e.g. change in movemen t pa ttern , pain-reproducing manoeuvres) were also consis ten t with a peripheral source. In the case of Skye, it is crit­ ical to consider that peripheral and cen tra l chan ges are not exclusive and elemen ts of both can be present.

reduction in press ure occ urs without a ny motion of the rib c age o r pelv i s , i t is considered to be largely a res u l t of TA contraction ( R ic hard son et a I . , 1 9 9 9 ) . However, when motion o f the rib cage o r pelvis is produced , other muscles are then i nvolved ( e . g . OE) . F a i l u re to i nstruct the patient about these o ther pos­ sible mechanisms for decreasing pressure (or fai lure to iden tify them) may result in pra ctise o f a n i n appro­ priate contra c tio n . A l t h o ugh Skye was i n s t r ucted to keep the rib cage in contact w i th t he bed, s he had fo u n d this difficult to perceive.

I n Skye 's case, the red uction in length of the h a mstring muscles acted to l imit hip motion and res u l ted i n an i ncreased demand for motion at the lumbar spine. This wo uld occ u r partic u l ar ly at the level where there was a tra nsition between the regions of h i g h and low mob ility ( i . e .

Althou gh the deep muscles a re able to

to continue her training in prone ly i n g using visual feedback from the mirror. Eva luation of the postural correction exercise i ndicated that she still required a great deal of concentration to ach ieve the desired position and was finding this d i fficu lt to accompl ish at work. Passive j oint movement techn iques were reap­ plied with progression or duration or the sustai ned pos teroanterior pressure to L4 and performance of the L4-L S l ateral fl e xio n PPIVM at grade IV Transverse mobilization was repeated at the same g rade but in an increasing degree or lateral flexion of the trunk to the right to move rur ther into the range or motion. In view of the improvement in her symptoms, but considering the slow rate of change i n Skye' s abi lity to perrorm a contraction of TA , she was given 1 month to practise the exercises independen tly. She was i nstructed to increase the number and duration or the contractions according to what she was able to manage. She was also instructed to use palpation and observation of the activ ity of OE as a gUide to this progression.

Bii'i1'i§i." I&B9" i§.i_ Over the next 6 months, Skye was seen initially monthly ( ror 2 months) and then every second month. The main limitation to her progress was the slow rate of change in her trunk muscle fu nction. She required long periods between treatmen ts in order to be able to detect a change in her abil ity to perform the contrac­ tion errectively. Deep m u s c l e con tro l

After t h e fir s t month, Skye h a d mastered the ability to perform a contraction or TA independently from the superficial abdominal muscles. Additional exercises were included to improve activation of the lu mbar multiftdus. For the first exercise, Skye palpated her multifidus in Sitting and performed gentle isometric contractions in combination with TA . She required spe­ cific instruction as to the correct hand placement and feeling for the appropriate contraction. Correction of the preciSion or the exercise was required at several ses­ sions berore the exercise could be perrormed optimally. Skye was a lso taught to perform a co-contraction of these two muscle groups during more functional tasks such as wailctng. She was encouraged to palpate the muscles initially in order to determine whether they were active and then to superimpose stepping.

I n c orporation of deep and su perficial m u scles

During this 6-month period, Skye prog ressed to the stage where she could perform a contraction or TA and reduce the pressure in the cufr placed under the abdomen by 4 mmHg. At this point, exercises to retra in the coord ination between TA and the superficial muscles were also commenced. These exercises started with her positioned in crook lyi n g with the i n ll ated pressure cuff under her lumbar spine. She was instructed to let her knee gently move out to the side without changing the pressu re i n the cuff, in an attempt to i ncrease rurther the load required ror spinal stabilization wh ile promoting dissociation with limb movement. This was gradu ally progressed to sliding one leg out stra i g h t and then l i rting her leg. Al l exercises wer e performed without letting the pressure change d uring the exercise. Other exercises included si ngle limb movemen ts a nd then con tra lateral arm and leg movements i n fou r-point kneel ing. and arm movements while sitting on a ball. For each or these exercises . Skye was instructed to contract her deep muscles prior to the addition or the load or the arms and legs. She was also encouraged to adopt a con­ trolled neutral spine position (using the method she had been taught prev iously) and to maintain this during the movements. Exerc ises were progressed after she was ab le to per­ form them accurate ly. For most exercises . she required some form of feedback. either from a pressure culT or mirror. to help to ensure that she kept her spine con­ trolled. Throughout this time, Skye continued to train her TA in prone ly ing. gradua lly increasing the holding time and the number or repetitions. She also continued to train the multifidus in standing with self-palpation of the co ntraction. The use of passive techniques made no rurther change to her symptoms and were, therefore. ceased. This allowed Skye to rocus on performing the active exercise regimen.

for more than a few seconds . This appeared to occur mostly when she tried to move or position her toes or ankle. She often noted that her right toes and ankle were c ooler than on the opposite s id e . Her physician had advised her to begin a nti­ inflanunatory medication (naproxen 375 m g twice daily). which she took sporadica lly. T iffany used the medication for the first 2 weeks after the second injury and then d isconti nued it. but she was unsure whether the medication had been of any benefit. She also applied extra moisturizing lotion on her forefoot daily to overcome dryness (Fig. S.l) and maintain normal skin tex tur e . Tiffany said she had no previous history of ankle injuries or any history of spinal complaints. She hac! no present symptoms/problems elsewhere and her gen­ eral health was unremarkable . Her goal is to return to her cheerleading squad as soon as possible and to par­ tiCip ate in a cheerl ead ing competition Ln 2 weeks.

REASONING DIS CUSSION AND CLINI CAL REASONING COMMENTARY

What were your th oughts regarding the mechanism of the second injury and factors contributing to the injury?

• Clinician's answer Tiffany was not exactly sure. but she thought th at

the ankle tu r ned ove r lateral ly after a jump man­ oeuvre. By her description . I felt that she had prob ab ly sustained an i nversi on ankle sprain that involved all of th e lateral soft tissue structur e s . The i n it ial injury may have compromised her proprioceptive c apabi l ities and/or modi fied her motor pattern sec­ ondary to low-grade nocicep t ive pain mechanisms. Furthermore, the activity of tumbling can be unpre­ dictable concerning l a ndings. The second injury

could have occurred because the tissues were still inflamed with slight nocice p tive pain present from the init ia l injury. What were your working hypotheses at this stage about the possible sources for Tiffany's symptoms and disability? What findings so far supported an d negated these hypotheses?

• Clinician's answer My working hypothesis at this time was that T i ffa ny had co m plex regional pain sy ndro me type II (causalgic-type pain p atte r n ) with peroneal ner ve involvement (Harden et at.. 2001: Janig and Stanton­ Hicks, 1996). She displayed ne u ral imp air men t with vascular instab i l i ty. Primary hyperalgesia from injured tissue in the ankle region, and possibly sec­ ondary hyperalgesia from adjacent uninj ured tissue Uanig and Stanton-Hicks, 1996), char a cteriz ed her pain. The trauma seemed to involve the peron ea l n erv e p rod uci ng an abn orm al state of afferent impulses (sympathetic fibres) leading to abnormal regulation of blood now (changes in colour and tem­ perature ) and sweating (dr y ness) . Distorted infor­ mation processing in the spinal cord ap pe ar ed to be possible as indicated by the ab n or mal muscle resp onse in the toes (toes sh a k in g) . Neurogenic inflammation was also considered, as were capsular trauma a nd talar dome fracture. The plain radio­ graphs eliminated any epip hyseal injury. but more sophisticated imaging would be required to r ul e out osteochondral injury co mp l etely.

Headache in a mature athlete Gwendo/en Jull

!!! UBJE.f.TIVE EXA M INATION .

Shirley was referred by a sports physician who she had consulted regarding her asthma. She was also suffering from almost daily frontal headaches. She has been having regular phy siotherapy on and orr ror the past year in conjunction with massage but had achieved no permanent relief. She had a motor vehicle accident (MVA) .35 years ago at which time she frac­ tured her thoracic spine. Although Shirley had some cervical stiffness. radiographs had shown only mild exit canal narrowing with no deterioration in the past 5 years. The sports physician believed that the stifr­ ness was contributing to her headaches. Shirley is a 54-year-old female who owns and works in her own retail business. She is also an ath­ lete who trains and competes in canoeing and has been successful at International Masters Games level. She had been training and competing in canoeing ror 15 years but in the last 2 years she has suffered from asthma and has had to ease of[ her training. The asthma is now under control and sl1e is starting to train again more seriously. This is more for her recre­ ational pursuits and desire for fitness rather than to compete at international level as her work commit­ ments and other newly acquired responsibilities pre­ clude her from dedicating the required time for this level of competition. Shirley reported that she had been suffering from headaches [or a long time and they certainly may have started before her MVA .3 5 years earlier. How­ ever. since the accident . she has always had troubles with her neck in some rorm. including wry neck

episodes and neck stiffness. as well as headaches. She reported that orten she can limit her wry neck episodes by concentrating on relaxation. but if the episode does not ease quickly. she consults a physiotherapist and attains relief. She also injured her vocal chords in the car accident. resulting in a hoarseness in her speech. Her new responsibilities include quite a deal of public speaking and ror the past 6 months she has been consulting a speech pathologist to assist with these problems. Currently Shirley sufrers from almost daily headaches or variable intensity. Some are severe and she is unable to runction while they are in the intense phase. which can last for several hours. These severe headaches are not frequent and Shirley cou Id not give any particular pattern that related to their occur­ rence. The moderately intense headaches are the more frequent ones. They last ror variable times from a rew hours to the whole day depending on how well she can intervene with either medication or attempts at relaxation or neck exercise. Shirley felt that she surrered only one rorm of headache and that all headaches were the same. except ror the intensity. The headaches are right sided. unilateral and in the frontal. retro-orbital area. The neck pain is less specific and is more a feeling of general neck pain and stiffness. There was no pain or discomfort reported in the rest of the race. upper limbs. thoracic or low back area. The headaches. whether moderate or severe. are consistently on the right side and do not change sides within or between headache episodes.

The focus was on ge n tl y pOSitioning the sc ap ula back and down onto the chest wall and h o ld i n g the p O S itio n . The previ ous u n wan ted use of latissimus dorsi was corrected and the activity o f th e lower trapezi u s was inspected and palpated. Shirley was taug ht the exe rcise on the right and left sides sep arat el y.

Postural exercise

The use of these muscles was incorporated in a pos­ tural exercise in si tt i n g. First. the assumption of ne u ­ tra l u pri g ht posture was t a u g ht with cor re cti o n from the pelvis to ach i eve a neutral upright pelvic p osi tio n with a no r m al l umbar lordosis.

Sy m ptom b e h av i o u r

When first see n , Julie 's pain was persisting i n i t s ori­ ginal location (pains one . two and three). Most move­ ments and/or sustained postures, particularly left rotation combined with extension of the thorax, aggravated the mid-thoracic and left lateral costal pains. Cervical movements on their own were not a problem. Julie felt that she had never been able to take a deep breath since the time of the impact. She was able to type for 1 0 minutes and to sit unsupported for

� J D

3 0 minutes. She frequently changed positions for relief. She woke often during the nig ht and her most comfortable place/position to sleep was semireclined in a chair. Screening with respect to possible precautions and contraindications to physiotherapy examination and treatment (e.g. general health. present and past medications, spinal cord . unexplained weight loss. cardiac/v isceral dysfunction, special investigations. etc. ) were all negative.

What were yo u r tho ughts at th i s stage ?

• C l i n ician's answer Possibly a mechanical dysfunction (joint shift or flX­ ation) had occurred during the impact and had not been cor rected nor spontaneously recovered. When an articular block is present. exercise tends to increase the local pain. When the problem is mechan­ ical . anti-inflammatory medication has l ittle long­ term effect since inflammation is not the primary source of nociception. Analgesic modalities do not affect the biomechanics of a blocked j Oint: therefore, any pain relief would only be temporary.

enjoys, this did not appear to be creating any dysfunc­ tional health beliefs or behaviours and I did not feel t hese emotions were going to interfere with her com­ mitment to recover y. I always include psychosocial considerations in the management of my patients since we treat human beings not j ust thei r body parts . I try to create a positive envi ronment with realistic expectations ( for both myself and the patient) so that treatment can be optimized .

• C l i n i c i an 's an swe r Fu nctio n a l movements tests eval u ate the qual ity o f movement. segme n ta l ly a n d collec t ively. d uring active range o f motion. The movements tested i n c l ude cardinal plane motion (pure sagittal . coronal and tra nsverse planes) or combined movements. Positio n a l tests are passive tests that i nvolve observa­ tion (looking) and palpation (feeling) of bones . We look for ma rked differences in the resting position of one bone relative to a c a rdin a l body plane as well a s relative t o one another. T hese tests help t o detect joint fi xations. With fixations we are t a Uei ng about a j Oint that i s held beyond i t s physi ological motion barrier and ye t within its anatomical motion barrier (it is not dis­ located ) . What holds it there? The j Oint becomes exces­ sive ly compressed by muscle forces . which d u ring the inj ury contract to prevent dislocation . Sometimes, like in the knee, an in tra-articular structure ( meniscus) can m a i n ta i n the j Oint fixation. More often, the posi­ tion is held by compression [ro m the muscles that cross the j o i n t . When a j oi n t is fIXated , the resting position of the bones d oes n o t c hange when i t is examined i n n.ex­ ion. neutral or hyperextension. By comparison. posi­ tio n a l c h a n ges that are the res ult of muscle imbalance frequen tly change from the extended to n.exion posi­ tion . thus the need to test in a ll three positio n s .

• C l i n i c i an 's answe r In order to ex pla i n the abnormal biomechan ics that have occurred here and , therefore. the c l i n ical rea­ soning behind the tre atment chosen . i t is necessary to u nd erstand what occurs normally in rotation of the mid-thorax. During right rotation of the mid-thorax (T 3-T8). the fol lowing biomech a n ics are thought to occur (Lee. 1 9 9 3 : 1 9 9 4 a . b ) . The superior ver tebra rotates to the right and trans lates to the left (see

Fig. 10 . 1 ) . Right rotation of the superior vertebral body 'pulls' the s uperior aspect of the head of the left rib forward at the costover tebral joint. i nducing anter­ ior rotation of the neck of the left rib (su perior glide at the left costotransverse j oi n t ) . and ' pushes ' the su pe­ rior aspect of the head of the right rib backwa rd . i n d ucing posterior rotation of the neck of the right rib (inferior glid e at the right costotran sverse joint) . The left l ateral translation of the superior vertebral body 'pushes' the left ri b posterola tera lly along the l i n e of the neck of the rib a nd causes a postero la teral trans­ lation o f the rib at the left costotransverse jOint. Simultaneously. the left latera l translation 'pulls' the right ri b anteromedially a long the line of the neck of the rib and causes an anteromed ial translation o f the rib at the right costotra nsverse joint. An a n tero­ medial/ posterolateral slide of the r ibs relative to the transverse processes to which they attach is thought to occu r during axi a l rota tion . When the l i m i t o f this horizonta l translation is reached. b o th t he costoverte­ bral and the costotransverse l igaments are tensed . S tability of the ribs both a n teriorly and posteriorly is requ ired for the following motion to occur. Further right rotation of the s uperior ver tebra occ u rs as the superior ver tebral body tilts to the r i g h t ( gl ides su per­ iorly along the left s uperior costoverte bral joint and inferiorly along the right superior costoverte bral joint). This tilt ca uses right side nexion o f the superior ver tebra a t the l i mit of righ t rotation of the mid­ tho racic segmen t (see Fig. 10 . 2 ) . I n Julie ' s case, the s ixth thoracic r i n g (T 5 -T 6 . the left and right sixth ribs and all of their related j o i n ts) was not able to tra nslate latera lly to the right. This dysfu nction i nvolved all fo ur bo nes of tbe sixth thor­ acic r i n g and was not j u st the consequence of a restriction of o ne zygapophyseal joint nor o ne costo­ tra nsverse j o i n t . The passive accessory mobility tests revealed full motion at the zygapophysea l jOints as well as the costotra nsverse j oi n ts. although a greater passive force was req u i red to produce the motion . This resistance to movement (as opposed to l ack of move­ ment) produced a kink in the mid-thoracic spinal cu rve during all of the fu nction al movement tests as well as i n the passive phYSiological mobility tests of the sixth ring. The marked block ( h igh resistance) to rig h t lateral transla tion o f the sixth ring preve nted

the an teromed ia l translation of the l e ft six t h rib, re l a­ tive to the left tra nsverse process of T 6 , and the pos­ tero l a teral transl a tion o f the right sixth rib, rel ative to the right transverse process of T 6 , neces sary for left rotation o f T 5-T 6 and the s i x th ribs. During forced or sudden u ncontrol led rotation o f the mid-t horax. a segme ntal thoracic ring c a n become 'stuck' o r h e l d a t the limit of motio n . It is c u r­ rently th ough t that excessive compression of the articular surfaces occurs a t the moment of inj u ry, and th is compression m a i ntains the a l te red resting position. This compression i s the resu l t o f the central nervous system's response to t he sudden a fferent input i t is receiving from the defor m i n g a r ticu l a r structures. T h e central nervous system increases the segmental muscle ac tivity to preven t fur ther deform­ a tion o f the a r ticu l a r s tructures (Lee and Vleemi n g , 1 9 9 8 ) . This efferen t motor response is s u s t a i n e d by the distorted a ffere n t input from t he displ aced articu­ lar structu res . When the neura l tissue becomes sensi­ tized by the excessive central a fferent bombardment, fu rther lengthening of the system can provoke symp­ toms . This cou ld . in part. explain the positive slu mp test as wel l as the agg ravation of sympto ms with right rotati o n . A spontaneous efferent d ischa rge through the sympathetic system could be respo n s ible for the visceral symptom of nause a . Treatment, therefore, requires t h e normalization of the afferent input to the cen tra l nervous system such that the effere nt output to the segmental muscles ( a nd viscera) is red uced , the articu lar compression is relieved and the amplitu de of the j oint's neutral zone ( detec ted thro ugh passive accessory mobility testing of horizontal translation) is restored. In a biomechanical appro ach to treatment, this can be ach ieved through specific manu a l therapy followed by motor control re-ed ucation . With the p o o r re l i a b i l i ty of m a n u a l tech n i q ues to j u dge positional a l ign m e n t a n d m o b i l i ty, and the normal va riation a c ross the p o p u lati o n , h ow do you weight the s ignifi cance of yo u r m a n u a l exa m i nation fi n d i ngs i n reac h i ng a d i ag n o s i s a n d selecting a treatm e n t ?

• C l i n i cian's an swe r firmly believe ( b u t u n fortunately cannot prove) t h at when we test the i n ter-tester rel iability of a man­ ual techniq ue we often start by asking the wro n g

I

questio n . If t h e question is inappropriate, then the answer is not u sefu l . For exanlple, If we ask, 'How much is this jOint movin g? ' , we h ave to apply a stan ­ dard of what w e think is norma l . In other words. is this j oint mov ing more. less or the same as we think it should . As you mentioned , there is a wide variation of movement possibilities across the popu lation and, therefore, a n accu rate answer to this question is impos­ sib le because ' norma l ' is a moving sta ndard . What a re we reaUy comparing the motion with? Even if we ask the questio n . 'Do I feel the same amo unt of movemen t as the next tester? ' , I must apply a scale of motion ( L e. norma l, sti ff. hypermobile) to categorize wha t I am feel­ ing. Where does the standard come from? Someone who writes a book saying each segmen t should h ave so many degrees o f motion? Where d oes this information come from and, given the wide variation of ' n orma l ' , how can one number be adequate? When we i nterpret what we are feeling i n terms of amount of movement, there will be less consistency between testers. Instead . we need to evaluate motion within the same individual by comparing motion to levels above and below and on the left and right sides . Instead of emphaSiz i ng the quanti ty of motion (Le. stiff or l oose) , whic h we know is highly variable and unrel iable, we should be exa mining quality of motion . This resistance to motion, or lack thereof. is a n examin ation of the size a nd shape of the neutra l zone of motion ((rom zero to R1 or first resist­ ance ) , wh ich every j O int has. This is a dy namic feature of a j oint's intern al and external environment and is u nder ar ticu lar, myo fascial and neural infl uence. Researching qu ality o f motion . and n o t quantity. may provide us with better re liability between testers. When you watch a n experie nced clinician work and ask them what they are feeling, t hey often say, 'Th i s joint doesn ' t feel right. i t ' s gu mmy, o r i t gives way too e a s i ly ' . The i n experienced clinician will try to inter­ pret what they feel i nto a quantity of moti o n , 'f think this j o i n t is stiff or hyperm obile ' . They h ave yet to develop a n inventory of 'common feel ings ' . I s u ppose this is what you ca l l pattern recognition of sensory input. This, for me, is the development o f skilled manual technique. So to a nswer the second part of you r question, I weigh the significance of my m a n u a l examin ation t1 n d i ngs (of resistance not quantity of motion) h ig h ly when reaching a biomechanical d i agnosis. I do not reach a diagnosis based o n the fi nd i n gs of one test but rather on the res u l ts of the entire exami nation process. I look for resistance to motion or giving way

SUBJECTIVE EXAMINATION

Sally is a 16-year-old school girl u n dertaking her final year of schooling at an exclusive coed ucational pri­ vate school. She is from a family of t h ree children and one adopted daughter. Her father is a doctor and her mother a teacher at the same school attended by Sal ly

At 14 yea rs of age. she was a national level swimmer but had not been able to achieve this stand­ ard for the last 2 years because of difficulties with shoulder pain. She came to me on the recommenda­ tion from the physiotherapist mother of one of her II

swimming contemporaries.

History Sally's presenting problem was one of bilateral shoul­ der pain. as indicated on the body chart (Fig. 11.1). worse on the left. t hough the side dominance varied [rom time to time for no apparent reason. She had the

pain in both shoulders whenever she swam and developed an ache in the same areas after swimming. This ach e lasted for 2 to 3 hours after swimming and her shoulders generally felt 'sore' at all times when she was in peak swim training. Her worst pain was with butterOy, on both recovery and mid p ull -through aspects of the stroke. She also had similar pain with freestyle

Physiotherapist 3

T his physiotherapist had considerable experience in treatment of postoperative shoulders and worked in a sports-specific clinic. She was also experienced with national level sports teams. Treatment provided was shoulder and scapular stabilizing exercises (as far as could be ascertained from the description). Sally worked at the exercises but became disillusioned when the physiotherapist would not allow her to get back in the water to swim. It appeared that Sally probably did not give this programme a fair trial before looking elsewhere for assistance. Her mother's comment was 'It is hard to fit all that exercising in and swim and do homework'.

Physiotherapist 4

T his physiotherapist was a national level swim coach who had practised more as a swim coach than a physiotherapist. but who had specialist knowledge of swimming requirements and a depth of understanding of the psychological issues related to working with swimmers.

swimming was seen from that of earlier years. These features raised the question about whether Sally was using her shoulder pain as an excuse to back away from swimming without seeming to be giving up or failing to achieve in the same way as the older sister. However, a typical feature of high-level junior swimmers is hypermobility of the glenohumeraljoints coupled with altered muscle balance and control around the shoulder girdle in particular (Pink et aI., 1993; Scovazzo et al.. 1991). The history of a traction injury to the right shoulder as the original provoking incident seemed to fit a nociceptive presentation, with the likelihood that the other shoulder became painful as a result of Sally adapting her swim technique to try to avoid pain in the right shoulder. With the likely underlying hypermobility in both shoulders and the high load generated by swimming, particularly butter­ fly in which symmetry of stroke is essential. such a scenario seemed reasonable. With the advent of pain, muscle function around the shoulder girdle, and in particular in the rotator cuff. is likely to have been affected, such that an imbalance already present from the involvement in swimming would be accentuated. Therefore, while the potential for central sensitization and an affective component to be features of the pre­ sentation was definitely there, my favoured hypothesis

C o n tributin g factors As indicated above , I considered it highly likely that Sally had a strong contributing component of poor dynamic control of her shoulders. The particular fea­ tures of her story that support this hypothesis are the history of the pain associated speCifically with a sport that involves large repetition of the same action undertaken almost daily, with little chance. therefore. for recovery, added to little involvement in alternative physical activity and coupled with the stress of final year schooling. Knowledge of the loads required of the joints and muscles in swimming also led to support of this hypothesis and recognition of what is. in fact, a very common clinical pattern in high-level swimmers. Therefore, the reasoning supporting my hypotheses was based in part on Sally's particular presentation but also on my underlying recognition of the particu­ lar clinical pattern.

S al ly 's mother could be viewed in this light a nd , at the time. t h is was my m ain interpretation of her motives. However. so-called 'pushy' parents are commonly seen associated with i n divi d ua l sports such as swimming and this image did come to mind somewhat. particu­ larly listening to her description of the list of attempts to lInd an answer to Sally s problems. My hypo theses, ou t li n ed in the answer to Q ues t i on 1 about S a lly's mother's influence on prognosis in p ar ticul ar, contin­ ue d t h r oug h this part of the inter v i e w. The comment about difficulty fi tti ng in the exercise w it h s t u dyi n g and s w imm ing did make me question their commit­ ment to success of a managemen t programme. I d i d find it in teresting that this fa m i ly had aban­ doned traditional pathways in th e i r attempts to solve Sally's pr o blems . with their use of a ch i ro practor. a l t ho u gh this sounded like it was short lived. and the apparent success of glucose injections despite their inabilit y to explain the hy pothesized mechanisms by which glucose injections would help painful shoul­ ders in an adolescent swimmer. Clearly, the injections had been ben eficial. but what surpr is ed me was that neither mother nor dau ghter had any idea of the pro­ posed mechanism of their effect.

Sally appeared to h ave little i ntrinsic pa t hology in her

The questions raised earlier a b o u t a ' p u shy ' mother were not sup­ p or t e d d u ring the m a nagement pe r io d : her mother was shown to be compassionate and concerned but n o t overbear i n g .

1998).

At this stage. the dilTerential diagnosis of patellar ten­ donosis could be largely discounted for three reasons. 1. There had been no reported increase in eccentric loading of the quadriceps during training or match play. Tendonosis is usually provoked by an increase in eccentric loading of the quadriceps muscle. 2. The particular quadriceps exercises given should not have markedly worsened the symptoms as there is less tension in the tendon during knee extension and straight leg raise than during eccen­ tric activities. 3. The MRI did not demonstrate any degenerative change in the patell ar tendon,

Lack o f flexibility o f T FL can b e further conflfmed in side lying by Ober's test (Brukner and Khan, 1993: McConnell, 1996). The Thomas test needs to be per­ formed on both legs so a comparison between legs can be made. The other muscles acting around the knee were more than adequately flexible. In fact, the ham­ string muscles were almost too flexible, with a straight leg raise of 100 degrees bilaterally.

• Clinicians' answer

The concentration of chemicals in an inflammatory

It was noted that the patient's age placed him in an age group with a high incidence of low back pain and that in his job he must flex and lift frequently. The patient's description of increasing peripheralization (McKenzie . 1981) of pain and paraesthesia typically occurs in the presence of intervertebral disc pathology or prolapse. The peripheralizing of back and leg symptoms over time also suggested the problem was progressive and his condition was worsening. As this disorder has marked consequences if neglected. it would be unwise to ignore the signU1cance of progressively increasing radiating symptoms in the search for more obscure causes for his p robl em

.

It was likely that the back and leg symptoms were

related. but back and leg pain are not always con­ nected. Supportive evidence was needed. which could be obtained by increasing and decreasing the lumbar lordosis (flexing and extending the lumbar spine in sitting) to test the effect of spinal loading on the leg symptoms .

D

condition does not generally reduce with change of position or unloading or exercise. Therefore. if the symptoms are intermittent or influenced by position. they are unlikely to be inflammatory in origin. Similarly. repeated moveme nt or prolon ged loading will either have no effect or will increase rather than decrease the symptoms. However, if the symptoms result from internal derangement of a lumbar disc. repeated movements in one direction may increase displacement and cause an increase in pain. while movement in the opposite direction may decrease dis­ placement and cause a decrease in pain. In this case. the pain was constant and so it could have been chemical in origin or have arisen from con­ stant m echan ical deformation. such as might occur

with

an

internal disc derangement. The behaviour.

however, suggested the pain was not primarily chemical in nature. It is improbable that pain related to inllam­ mation would appear and ctisappear on change of pos­ ition. The behaviour did tend to support the hypothesis that the symptoms were likely to have arisen from increaSing and decreasing mechanical disc deform­

The constant back pain was, therefore. most probably caused by an' internal disc derangement. which could increase or decrease. thus provoking in termittent pain in the leg according to the patient's position or movement. The reduction in leg pain on waU<ing a short dis­ tance may have been a consequence of the lumbar spine extension effect of walking. However. walking
