FROM THE PRESIDENT

Professor Rod Bonello

BSC(SYD), DO, DC(SCC), MHA(UNSW), FRCC BABIES AND BATHWATER AND A BRIGHT FUTURE. Recent media controversy February saw a media furor explode surrounding the appearance of a video of a chiropractor examining and treating a two-week old baby. Although the baby was in no danger, a public outcry followed based on the emotional reaction caused by the footage. Following that, familiar calls came from the Victorian Health Minister and various other sectors to review the rights of chiropractors to treat children. So let’s unpack this complex situation.

What was the problem? The video was almost universally found to be confronting because it showed a baby made to cry during a treatment. Additionally, the inverted neurological test was depicted which involved the baby being hung upside-down by one leg. While in itself innocuous, the inversion of a baby looks to be cruel. The video contained a number of statements made by the chiropractor which could not be supported by evidence and which lacked biological plausibility and it is this feature which is objectively offensive under current societal standards. A clear distinction exists between what can be said by a registered professional privately and publicly. Experimental, unconventional and poorly evidenced treatments can be appropriate in individual circumstances under certain conditions - such as failure of more conventional treatments and having genuinely informed consent. Public statements, such as a posted video, cannot be individualised and are not given sufficient context so they must be far more

circumspect and precise in the messages they convey. Discussion and display of poorly evidenced procedures can give an inaccurate picture of their status and, effectively is akin to false advertising.

Generally speaking, should videos of this nature be posted? Of course not. No matter how skilled the chiropractor is for example, video of neck manipulation is virtually always confronting. Such video footage disrespects the sanctity of the doctor-patient relationship and is usually delivered without the specific context of the case, and this is enormously problematic.

What are the repercussions? In the long run there are three effects of unwise postings of paediatric videos. Firstly, the chiropractor who posts the video becomes open to scrutiny and risks having conditions placed on their practise if not loss of licence. Secondly, the profession is at real risk of having its right to treat children under a certain age removed. Thirdly, the profession suffers a loss in cultural authority. Cultural authority is like having an excellent reputation; it is difficult to acquire but so easy to lose.

We have also participated vigorously in various media interviews and they are still ongoing in March 2019. Our role is to clarify for the public and other stakeholders that, notwithstanding the fact that the posting of such videos is usually wrong, and not necessarily seeking to defend any individual procedures depicted in that video, care for infants and children is a valid component of chiropractic practice. Although it is an emerging area of validated practice there are key areas for which the evidence is in fact reasonable. Further, the calls for the wholesale ban of chiropractic care for babies, infants and children are unfounded and not in the best interest of the little ones and their families. We have also sent out a communiqué to all members about paediatric care by chiropractors, its place in practice and the state of evidence at this time. We are also commencing a service for members to give advice on their website content to help ensure full compliance with applicable standards (see below).

Member Website Review The Board agreed to review member’s websites to help ensure that high standards of compliance are maintained. Like it or not, chiropractors’ on-line presence is under great scrutiny and we have determined that it is our role to facilitate members in having clear messaging for the benefit of their patients and content that will not jeopardise their status with the Chiropractic Board of Australia.

What is CA doing about this? Several things. At the time of writing this report the chiropractor who posted the video is under investigation by the Chiropractic Board of Australia, having already accepted not to see children under the age of 12 years until the investigation is concluded. Because this investigation is ongoing I have not commented on the specifics of his case. However we have reached out to the chiropractor at the heart of the controversy. Our role is educative as much as anything else.

Interview with Dr Adrian Traeger By: Matthew Bulman BHSc, MChiro

Dr Adrian Traeger is a postdoctoral research fellow at the Institute for Musculoskeletal Health, a division of the School of Public Health, University of Sydney. He is a physiotherapist who has worked in primary care for over 10 years. He completed his doctorate at NeuRA, UNSW, which focused on how best to reassure patients with low back pain, and has been actively researching and publishing in the area of back pain. He was kind enough to find some time within his busy schedule to answer a few questions for our membership. Q1. You have been publishing some fascinating and influential research in the area of back pain, and most recently, “Effect of Intensive Patient Education vs Placebo Patient Education on Outcomes in Patients With Acute Low Back Pain A Randomized Clinical Trial.” in JAMA Neurology This trial investigated the question, “Is intensive patient education effective as part of first-line care for patients with acute low back pain?”. Guidelines suggest this to be an intervention strategy. What did you find in your trial? And what are the implications and recommendations for practice? It was certainly an interesting trial to be part of. Up to this point we really had no robust evidence that patient education could influence outcomes in people with acute low back pain. We felt patient education was the most likely treatment to work; we had evidence it was reassuring, and hypothesised that high quality reassurance was the key to recovering. Other physical and psychological treatments hadn’t shown much promise for these patients. Patient education was the one thing we felt could change the trajectory of acute low back pain, through two pathways: a direct pathway (reducing threat of pain, therefore reducing pain intensity) and an indirect pathway (encouraging gradual return to activity and work). In the trial we had 2 groups of 101 patients with acute low back pain. The intervention group received 2 x 1hour sessions of patient education based on the book Explain Pain. The control group received placebo patient information, which was everything the intervention group received – time with practitioner, empathy – minus the information and advice-giving component. What did we find? To our surprise, the intervention had no effect on our primary outcome, which was pain intensity 3-months after the onset of pain. This was really challenging to accept. Many believed, including me,

4

CA NEWS MARCH 2019

that what you say to a patient can have important impact on outcomes, whether that be indirectly through encouraging positive behaviors (e.g. taking an active approach to recovery) or directly, by changing the threat of pain. Our trial really turned those theories on their head. Q2. This trial has caused a lot of uproar on social media, as well as in different clinical and scientific corners of the world. What is your perspective of social media for clinicians, researchers and health consumers? I think social media is a great way to amplify the messages coming from research. Some of the detail and nuance of the science is inevitably lost in short-form, which can be problematic, but in general it seems like a useful way for clinicians and researchers to keep up with research. With regard to the uproar about our trial, it wasn’t wholly unexpected. We tested a popular treatment, one that is taught around the world. Nobody likes to think that the approach they advocate for, with the very best of intentions for their patient, is ineffective. The beauty of science is that the results of our trial are not a matter of opinion–they are a simple fact. The question now is what can we do with this new knowledge to improve patient care? Q3. Another area of research you are involved in is reducing unnecessary imaging for low back pain. Chiropractors are very split in this area, with the research community and evidence based chiropractors aligned with best practice, hoping to reduce

lower risk of harm. We know that routine imaging has no benefits for back pain without features of serious pathology, but substantial risk of harms (e.g. radiation exposure, distress caused by pathoanatomic labelling, further unnecessary tests and procedures). By following guidelines you avoid exposing your patient to these harms.

There are all these other factors at play in that intervention: expectations, emotions, the relationship with the practitioner. So if something believed to be inert (e.g. sugar pill) is having an effect on a person’s outcome, rather

and risks associated with unnecessary imaging. It is a very complex issue though. My feeling is that we need a big cultural shift in how we think about low back pain, if unnecessary imaging rates are to drop. As long as people (clinicians and patients) believe you can see pain on an imaging scan, they are probably going to want the test. There are also medicolegal concerns that drive a lot of imaging, not wanting to miss something. These cases are rare but catastrophic for the patient and the clinician involved. We need to think of new ways to protect both parties without resorting to routine ‘defensive’ imaging. Q5. You also recently published an article, Lumbar spine fusion: what is the evidence? What should clinicians and the public know about Lumbar spine fusion as an intervention? Don’t do it for back pain! The available evidence suggests no benefit of spinal fusion, but the costs are huge, and the surgery carries a substantial risk of harm. Q6. You and Steven Kamper published an article examining the concept of placebo, asking if it is time to abandon the concept. What are some of your thoughts on placebo, contextual effects and the clinical encounter?

exploring? I am working on campaign to raise awareness of overdiagnosis. Overdiagnosis occurs when a person is given a diagnosis, for example from a health practitioner, that causes more harm than good. An example of this could be giving a person the diagnosis of a ‘disc bulge.’ There is no robust evidence that providing pathoanatomic diagnoses such as this can improve outcome. However, we do know that such labels can make recovery slower, increase healthcare use, and increase surgery. Overdiagnosis doesn’t just happen in musculoskeletal conditions; there are examples in many other medical fields such as cancer, cardiovascular disease and mental health. Q10. You seem to be interested in shifting health literacy for the public’s benefit. What ways can we better improve health literacy? How can evidence based chiropractors help? I am very interested in empowering the public to make informed choices about their healthcare. That is one thing we know patient education can do: reduce fear about illness and reduce healthcare utilisation. Not a great business model for a practitioner in private practice, I know, but I think chiropractors could really set themselves apart from the pack if they could

Interview with Professor Stephen Perle By: Amber Beynon B.Sc. (Hons), B.Chiro

Professor Stephen M. Perle, D.C., M.S., holds a tenured appointment as Professor of Clinical Sciences in the University of Bridgeport, College of Health Sciences, School of Chiropractic. He is the first chiropractor in the U.S. to be appointed to a university’s faculty to teach chiropractic and the first one to reach the rank of professor. Professor Perle will be a special guest speaker at the Chiropractic Australia National Conference in August and was kind enough to take some time to answer a few questions so we can get to know him before the conference. Q. What are the professional achievements of which you are most proud?

conducting research. I think there are more questions than answers. This is very pie in the sky but I think researchers have to do what interests them and they can fund. Because of a friendship with a mass communications professor at the University of Bridgeport I have now started to do research on how the media portrays our profession. That is something I would have never predicted 5 years ago and I think has value.

I’d say I have had two professional careers. Firstly, I have been involved in sports medicine since my time in high school. I joke that I practiced medicine without a license starting at age 14 as my high school’s first athletic trainer (I believe Australians call them sports trainers). I continued in sports medicine doing that as a chiropractor culminating with my being the medical director of the 1991 Mobil USA Outdoor Track

However, if I were to run a chiropractic research fund my focus would be on comparative and cost-effectiveness research as well as trying to find ways to improve our outcomes, for example, dosage research and preintervention predictors of outcome, both patient characteristics and clinical prediction rules to allow more effective treatment choices.

Applying for NHMRC funding is an intensive process, no matter what scheme you are applying for. The NHMRC funding schemes have been updated (https://nhmrc.gov.au/ funding/new-grant-program/overview) and this year marks the first year with new rules and structure for applications. One of the most notable changes is that the investigator grant scheme will now include some project grant funds in addition to salary and runs for five years (not four years). Additionally, the

proportion of funds allowed to investigator grants has increased to 40% of the entire NHMRC funding budget whereas previously fellowships and scholarship accounted for only 16% of the funding budget. This year investigator grant applications are due to NHMRC by 6th February for funding to commence in 2020. For anyone considering applying for any NHMRC funding, whether for an investigator grant or project related funding, my recommendation is to start early and allow for plenty of time. Don’t underestimate the number of edits and revisions needed in this highly competitive scheme. It is not something you can do overnight.

Underpinning the group’s productive culture are core values of integrity, openness, and inclusivity. The multidisciplinary group includes researchers and clinicians from diverse backgrounds such as public health (incl. clinical epidemiology, health economics, and biostatistics), medicine (incl. rheumatology, orthopaedics, emergency medicine, and general practice) and allied health (incl. physiotherapy, pharmacology, exercise physiology, and chiropractic). On behalf of Chiropractic Australia, President Prof. Rod Bonello sent Prof. Maher and his team congratulatory wishes on their stellar launch and important work in the field. Through a PhD scholarship administered by the Chiropractic Australia Research Foundation (CARF), Chiropractic Australia is supporting a chiropractic researcher (Dr. Laura Montgomery) to undertake a much-needed program of

study in adolescent musculoskeletal health at the IMH, commencing later this year. For more information on the Institute for Musculoskeletal Health visit their website imh.org.au and follow them on Twitter @ msk_health

Static palpation is widely used by chiropractors and manual therapists, but is it reliable? By: Amber Beynon B.Sc. (Hons), B.Chiro Static palpation is commonly used by chiropractors and manual therapists, however, it is not really known if it is reliable or not, particularly within the thoracic spine. The authors set out to determine the agreement of thoracic spine static palpation to test for a manipulable lesion using stiffness or tenderness as diagnostic markers, and determine the effect of standardised training for examiners. They also wanted to explore if there was an expert consensus on the level of segmental tenderness required to locate a “manipulable lesion”. The authors used two experienced chiropractors to palpate the thoracic vertebrae on two occasions (pragmatic and standardised approaches), asking the participant about tenderness and judging segmental stiffness (N=36). Additionally, an expert panel of 10 chiropractors took part in a Delphi process to identify the level of meaningful segmental tenderness required to locate a “manipulable lesion”.

Overall, the reliability for stiffness when adjusted ranged from slight to substantial agreement, with moderate or substantial agreement demonstrated at the majority of spinal levels. Generally, there was fair to substantial agreement for segmental tenderness. Training did not significantly improve interrater agreement for stiffness or tenderness suggesting that the pragmatic approaches used by two experienced chiropractors were equivalent. The Delphi process indicated that a pain score of 2 out of 10 identified a potential “manipulable lesion” suggesting that tenderness should not just be a yes/no question. In a study of this nature, it seems preferable to use the NPRS and a potential manipulable lesion is scored as a pain score above 2 out of 10.

There was overall moderate reliability for static palpation for stiffness and tenderness, with tenderness showing a higher level of reliability. The findings lined up with many previous studies in that tenderness was more reliable than just testing for stiffness. The study did however actually find higher agreement for static palpation then many others as within the analysis they accounted for certain biases that can occur within reliability analysis. Nevertheless, segmental assessment for stiffness alone is not sufficiently reliable but improves when considering a region (multi-levels of vertebrae). Summing up clinically, the advice is to assess your patient for more than just stiffness and ask the patient about tenderness as well.

Interestingly there was a higher level of reliability of static palpation within the mid-thoracic spine when assessing for stiffness. The authors speculate that the anatomy of the thoracic spine in the mid-region may be easier to palpate given its flexibility to anterior forces in a prone position.

Manipulation-induced hypoalgesia in musculoskeletal pain populations: a systematic critical review and meta-analysis By: Sasha Aspinall B.Sc. (Chiro), B.Sc. (Hons), B.Chiro Reduced pain sensitivity after spinal manipulation has been observed in both symptomatic and asymptomatic populations. But we don’t yet have any convincing evidence about whether changes in pain sensitivity after spinal manipulation are specific to the treatment and clinically relevant. So we decided to perform a systematic critical review with meta-analysis with the purpose of investigating changes in quantitative sensory testing measures following high-velocity lowamplitude spinal manipulation in musculoskeletal pain populations. Our objectives were to compare changes in quantitative sensory testing outcomes after spinal manipulation vs. sham, control and active interventions, to estimate how much pain sensitivity changed over time, and to determine whether changes were systemic or not. We were able to include fifteen randomised controlled trials, of which thirteen measured pressure pain threshold (PPT). Four of the PPT studies were sham-controlled. Our first metaanalysis found that there was no difference in the change in PPT after spinal manipulation compared to sham manipulation. In contrast,

our second meta-analysis found that PPT increased significantly over time after spinal manipulation by a mean of 0.32 kg/cm2, which occurred systemically. Unfortunately, there were not enough studies comparing to other interventions, or for other types of quantitative sensory tests, to make robust conclusions about these. So to summarise, we found that while PPT decreased throughout the whole body after SMT in people with musculoskeletal pain, our meta-analysis provided low quality evidence that this is not significant when compared to sham manipulation. We have some concerns with the sham manipulations that were used, and the studies were generally a bit disappointing in their quality, so we can’t be really confident with this result. We noticed though that changes in PPT didn’t seem to occur at all after lumbar manipulation, so there could also be a difference in how different spinal regions respond to manipulation.

tests like PPT is not clear. We have evidence that people with chronic pain problems tend to have increase pain sensitivity compared to people without ongoing pain, but we don’t know whether changes in pain sensitivity after particular treatments relate to symptomatic improvement in patients. So when you put that together with our result suggesting there might not be a difference compared to sham, we really can’t make any clinical recommendations off the back of this research. We believe that future research in this area should really focus on high-quality sham-controlled trials, on the clinical relevance of changes in quantitative sensory tests, and on other types of quantitative sensory tests like temporal summation.

Abstracts LONG-TERM RESULTS OF SURGERY COMPARED WITH NONOPERATIVE TREATMENT FOR LUMBAR DEGENERATIVE SPONDYLOLISTHESIS Experts compared the 8-year outcomes between surgery and nonoperative care and among different fusion techniques for symptomatic lumbar degenerative spondylolisthesis (DS). They enrolled the surgical candidates with DS from 13 centers with at least 12 weeks of symptoms and confirmatory imaging in a randomized controlled trial (RCT) or observational cohort study (OBS). Significantly greater improvements in pain and function for patients with symptomatic DS were seen in the patients who received surgery compared with nonoperative treatment through 8 years of follow-up. The outcomes were not affected by the fusion technique. Similar outcomes were noted among patients treated with uninstrumented posterolateral fusion, instrumented posterolateral fusion, and 360° fusion. Abdu WA, et al.

Spine, November 16, 2018 A LIFETIME OF PHYSICAL ACTIVITIES PAYS DIVIDENDS In this cross-sectional study, investigators assessed 1,826 community-dwelling men and women in southern California aged 60–99 years who attended a research visit in 1988–1992 to identify associations between physical activity throughout the lifespan and cognitive function in older age. They observed improved cognitive function in those who had partook in regular physical activity regardless of intensity.

populations. It is unknown, however, whether MIH following high-velocity low-amplitude spinal manipulative therapy is a specific and clinically relevant treatment effect. Methods: Our objectives were to compare changes in quantitative sensory testing outcomes after spinal manipulative therapy vs. sham, control and active interventions, to estimate the magnitude of change over time, and to determine whether changes are systemic or not. Results: Fifteen studies were included. Thirteen measured pressure pain threshold, and four of these were sham-controlled. Change in pressure pain threshold after spinal manipulative therapy compared to sham revealed no significant difference. Pressure pain threshold increased significantly over time after spinal manipulative therapy (0.32 kg/cm2, CI 0.22– 0.42), which occurred systemically. There were too few studies comparing to other interventions or for other types of quantitative sensory testing to make robust conclusions about these. Conclusions: We found that systemic MIH (for pressure pain threshold) does occur in musculoskeletal pain populations, though there was low quality evidence of no significant difference compared to sham manipulation. Future research should focus on the clinical relevance of MIH, and different types of quantitative sensory tests. Charlotte Leboeuf-Yde, Sarah J. Etherington and Bruce F. Walker.

Systematic Reviews EFFECTIVENESS OF KINESIO TAPING IN PATIENTS WITH CHRONIC NS LBP. A SYSTEMATIC REVIEW WITH METAANALYSIS This study sought to investigate the effects of Kinesio Taping (KT) in patients with nonspecific low back pain as KT is widely used in patients with low back pain. The authors included only randomized controlled trials (RCTs) in adults with chronic nonspecific low back pain that compared KT to no intervention or placebo as well as RCTs that compared KT combined with exercise against exercise alone. They considered pain intensity and disability as the

primary outcomes. Whenever possible, the data were pooled through meta-analysis. They identified 11 RCTs for this systematic review (pooled n = 743) and concluded that there was very low to moderate quality evidence shows that KT was no better than any other intervention for most the outcomes assessed in patients with chronic nonspecific low back pain. We found no evidence to support the use of KT in clinical practice for patients with chronic nonspecific low back pain.

Investigators analyzed cases diagnosed with adolescent idiopathic scoliosis (AIS) of age ≤ 18 years and treated with a thoracolumbo-sacral orthosis (TLSO) to assess the forbidden factors of brace treatment consequences ie, failure and/or success. They recorded a sum of 19 radiographic and 8 clinical predictive factors with multiple types of TLSO braces like Boston, Wilmington, Cheneau, Osaka Medical College, Dresdner Scoliosis Orthosis and SPoRT. They observed an association of lack of initial in-brace correction with treatment failure. They suggested a link of brace wear time with failure and success with the moderate evidence. van den Bogaart M, et al.
