A Lasting Legacy... A Pivotal Gift
About Michael G. DeGroote and his gift In 2003, businessman Michael G. DeGroote made history when he made the largest single donation ever to a Canadian university or institution. His donation of $105 million has had a wide impact on health sciences research, education and care, and accelerated the pace of discovery at McMaster.
“Mr. DeGroote was a tireless advocate for advancing the management of pain and promoting research of novel therapeutics, including medical cannabis.” - Dr. Jason Busse, Director of the Michael G. DeGroote National Pain Centre McMaster’s Faculty of Health Sciences followed a “people first” strategy in allocating the $105 million gift from Mr. DeGroote. Emphasis was placed on hiring international caliber experts in health education, research and care, particularly in the areas of pain, infectious diseases, stroke prevention and cancer. One of the key initiatives was the Michael G. DeGroote Institute for Pain Research & Care, which received a $15 million endowment. “With this gift,” Mr. DeGroote said, “I know McMaster will be able to make new breakthroughs and make a real difference in more people’s lives.” Michael G. DeGroote died in September 2022, at the age of 89. Though he is no longer with us, his generosity and philanthropic efforts ensure his legacy will live on and enable innovation in research for years to come. 4
“We have been fortunate in the past year to see support from the federal government for patient advocacy across the country, and the creation of one new interdisciplinary provincial society, called Pain Ontario. We continue to advocate for increases in pain specific research funding.” - Dr. Norm Buckley

Institute for Pain Research & Care - Digital Impact & Media Presence We live in a digital age where the Internet and social media have become a critical component when it comes to knowledge translation and engaging with target audiences. This past year, the Institute for Pain Research & Care and the National Pain Centre (NPC) set out to build their presence - both in traditional and digital media. The overarching goals were to continue to establish ourselves as national leaders in chronic pain research; increase overall media presence; foster partnerships with other health research institutes and organizations; increase knowledge translation initiatives of institute-funded research and foster and grow relationships with potential donors. Modest targets were set in all these areas to determine a realistic baseline to help inform future goals.
Website This year saw the Institute and NPC undergo a redevelopment of their websites. The new design incorporated additional features to meet the Accessibility for Ontarians with Disabilities Act, as well as switched to a new content management system that was implemented across the McMaster campus. One of our primary objectives has been to increase the number of visitors to our website. Since their launch in February, the websites have experienced significant traffic, with the Institute receiving more than 1,000 hits each month and the NPC receiving nearly 2,000 hits. This next year will focus on Search Engine Optimization to improve organic search rankings, as well as improving the bounce rate (number of visitors who leave after only seeing one page) for both sites.
Social Media Building a substantial Twitter following is vital for amplifying our research messages. Twitter has been our most prominent platform for disseminating research updates and engaging with audiences. This past year saw the NPC’s Twitter account gain nearly 500 new Twitter followers - an increase of more than 40%. Our engagement rate on Twitter posts has also shown steady improvement. The last year saw our engagement rate rise to an average of 4% per impression - an engagement rate between 1% and 5% is considered to be good. Our social media channels earned more than 19,000 impressions, which was an increase of more than 80% over last year’s reporting period. These metrics suggest that our social media efforts are seeing success and that our content is resonating with followers and generating meaningful interactions. The Institute also launched a LinkedIn page as a new way to assist with knowledge translation initiatives. One of our goals for this coming year will be to better utilize this platform as a means of reaching our target audiences.
Traditional Media A few notable highlights from the Institute and Pain Centre’s representation in traditional media this past year include Dr. Norm Buckley’s appearance on an episode of CBC’s The Current, discussing the impact of pain on the lives of those living with it and addressing the gaps in policy and pain research. The Institute also saw the publication of the first in a series of five articles with Open Access Government, addressing issues surrounding the use of opioids.

Institute for Pain Research & Care Graduate Studentships Maram Khaled, BSc, DC, MSc PhD Candidate Project Title: Postsurgical Pain and Neurocognitive Outcomes After Non-Cardiac Surgery in Older Adults Supervisor: Dr. Maura Marcucci
Brief Overview and Progress to Date Chronic postsurgical pain (CPSP) may increase the risk of postoperative cognitive dysfunction (POCD) directly or through negatively impacting mobility. A comprehensive measure of satisfaction with surgery that accounts for ability to perform activities might be even more strongly associated with POCD. There might be complex mechanisms underlying the interplays between postoperative pain and cognition. In this prospective cohort study we aim to explore whether CPSP at 6 months is associated with POCD (≥2-point decline in the Montreal Cognitive Assessment (MoCA) compared to preoperative) at 12 months. We will also explore the association between satisfaction with surgery and POCD; the role of pain medications (opioids) in the association between CPSP and POCD; the role of patient preoccupation /optimism and coping in determining the effect of pain on cognition; and the hypothesis of neurogenesis-interference as an underlying mechanism. Patients ≥50 years old undergoing elective total knee/hip arthroplasty are included. Socio-demographics, comorbidities, pain, and pain

It will inform larger confirmatory and interventional studies to enhance perioperative care.” - Maram Khaled
medications are assessed preoperatively. Patients are followed upto 12 months postoperatively to measure coping (SPOC questionnaire), pain and satisfaction. MoCA and neuropsychological tests are administered at baseline, 4-6 weeks, 6 and 12 months. Blood is longitudinally collected for biomarker analysis. Recruitment has been completed with 80 participants enrolled in the study. So far, 22 participants have completed the study.

“This study has the potential to guide future research on the development of preventive interventions in managing pediatric postsurgical pain.” - Cheryl Chow
Project Title: Predictors andTrajectories of Pediatric Postsurgical Pain Supervisor: Dr. Norm Buckley & Dr. Louis Schmidt
Brief Overview and Progress to Date Postsurgical pain affects up to 1 in 5 children undergoing surgery in Canada each year. It is associated with myriad of adverse clinical, psychological and developmental sequelae including increased analgesic use, delirium, delayed recovery, and fear of future medical care. Although the impact of postsurgical pain in adults is wellestablished, the literature on postsurgical pain in children remains largely unclear and incomplete. The extrapolation from adult data is limiting because children experience, express and perceive pain differently than adults. To date, only a handful of studies have described the course of pediatric postsurgical pain and no studies have examined the predictors and trajectories of pediatric postsurgical pain using objective and valid neurophysiological measures. Given these shortcomings and needs, the proposed project will aim to establish biological, psychological, and social predictors of the development on pediatric postsurgical pain and its trajectory. Moreover, this will be the first study to examine the associations between biomarkers (i.e., EEG, cortisol and heart rate) and pain in pediatric surgery. The findings of this project may help to clarify the roles of anxiety, stress and parental factors on acute and persistent postsurgical pain.

Institute for Pain Research & Care Fellowships Shirin Modarresi, MSc, MPT, PhD Postdoctoral Fellow Project Title: Pain CareYoga for People with Knee Osteoarthritis: A Feasibility and Pilot Randomized Controlled Trial Supervisor: Dr. Lisa Carlesso
Brief Overview and Progress to Date Osteoarthritis (OA), of which the knee is the most affected joint, is the leading cause of pain and disability in older adults, affecting more than 500 million people worldwide and significantly contributing to healthcare costs. Despite its high prevalence and widespread impact, no disease-modifying drugs are currently available, and the efficacy of the current available treatment options in alleviating pain remains limited. This project aims to address this gap in knowledge by introducing a program which we refer to as Pain Informed Movement. This unique intervention combines mind-body techniques with neuromuscular exercise and pain neuroscience education (PNE) and aims to improve endogenous pain modulation in people with knee OA. In this project we investigate the impact of the Pain Informed Movement program on pain intensity and pain modulation, which includes physical testing, questionnaires, and blood analysis of Brain Derived Neurotrophic Factors and Nerve Growth Factors. We have successfully completed the feasibility phase of the study and the results are accepted for publication
“This project will lay the foundation to inform a larger multi-site RCT to assess the effectiveness of the Pain Informed Movement program and provide an understanding its underlying mechanisms. The larger RCT will contribute to the clinical recommendations for management of knee OA pain for clinicians across multiple sectors.” - Dr. Shirin Modarresi
at the Osteoarthritis and Cartilage Open journal. Furthermore, the protocol for the next phase of the study, a pilot randomized controlled trial (RCT) comparing Pain Informed Movement to standard treatment (strengthening exercises and OA education), is also accepted for publication at the same journal. The pilot RCT is currently underway, and we anticipate completing this phase by May 2024, after which the results will be ready for publication.

Xiaoqin Wang, MD Postdoctoral Fellow Project Title: InterventionalTreatments for Chronic, Local or Radicular, Non-Cancer, Spinal Pain: A Systematic Review and Network Meta-Analysis of RandomizedTrials Supervisor: Dr. Jason Busse
Brief Overview and Progress to Date Chronic axial pain is common in Canada, and interventional pain medicine (IPM) procedures (e.g. trigger point injections) are commonly used. Given escalating use, and the associated costs, government payers are becoming increasingly concerned about the value of these services. Specifically, despite limited evidence of effectiveness, unpublished data from Health Quality Ontario (HQO) using Ontario Health Insurance Plan (OHIP) billing data indicate that the use of some IPM procedures have more than doubled from 2011 to 2015, primarily by an increase in the number of procedures without much increase in the number of patients. Several conventional systematic reviews have explored the effectiveness of interventional procedures for chronic noncancer spine pain; however, all have important methodological limitations. We conducted a systematic review and NMA of randomized trials to assess the comparative effectiveness of interventional procedures for chronic noncancer spine-related pain that addresses these limitations.

Brief Overview and Progress to Date Migraine is a common chronic neurological disorder characterized by episodes of pulsating headaches, often accompanied by symptoms like photophobia, phonophobia, nausea, and vomiting. Approximately 12% of people worldwide suffer from migraines, with women aged 15 to 49 being disproportionately affected. Selecting the right pharmacotherapy for migraines is challenging for physicians and patients. Medications can be divided into symptomatic (acute) treatments for active attacks and prophylactic treatments to reduce the frequency and severity of headaches

“Our study will help our understanding of perceived causes of chronic pain, which will help identify potential targets for prevention.” - Dr. Jason Busse
A Persistent Post-Surgical Pain Survey Primary Investigator: Jason Busse, DC, PhD Start Date: 2020
Brief Overview and Progress to Date An influential survey of 5,130 patients attending 10 outpatient chronic pain clinics found that 23% attributed their complaints to a surgical procedure. According to Google Scholar, this survey has been cited over 350 times; however, there are limitations with this report. The sample was restricted to patients in North Britain, there are no details reported regarding the response rate, and the data was acquired between 1989 and 1992. These issues suggest that generalizability to the current Canadian context is uncertain. We surveyed 756 Canadian adults living with chronic pain to establish to what cause they attributed the development of their pain, and what interventions they have pursued and perceived effectiveness. We are currently finalizing the analyses and drafting the manuscript for publication.

Institute for Pain Research & Care Seed Grants Feasibility of a Definitive Trial to Evaluate the Effect of Cannabinoid Oil, Versus Placebo, on Chronic Pain PostSurgical Pain and Functional Outcomes in Patients Undergoing TKA Primary Investigator: Jason Busse, DC, PhD Start Date: 2017
Brief Overview and Progress to Date Each year, approximately 67,000 Canadians undergo knee replacement surgery. Up to 20% develop persistent post-surgical pain - a complaint that is associated with depression, anxiety, unemployment and reduced quality of life. Moreover, chronic pain after surgery is often managed with opioid therapy, which typically provides only modest benefits and is associated with rare but serious adverse events, such as overdose and death. Several studies have found that greater pain just before and after knee replacement surgery is associated with the development of chronic pain, suggesting that reducing peri-operative pain may help prevent

chronic post-surgical pain. We have been pursuing a pilot randomized controlled trial to explore the feasibility of a definitive trial of peri-operative cannabidiol (CBD) to prevent persistent post-surgical pain after total knee replacement. We had to overcome several bureaucratic hurdles to receive Health Canada approval for our interventional product, but have now recruited 10 of our target 40 patients.

Institute for Pain Research & Care Seed Grants An Investigation into the Effectiveness of a New Transitional Pain Service (TPS) on Opioid Cessation After Broad Range of Surgeries Done at Hamilton Health Sciences (HHS) and its Affiliated Hospitals Primary Investigator: James Paul, MD, MSc, FRCPC Start Date: 2019
Brief Overview and Progress to Date Hamilton Health Sciences (HHS) affiliated hospitals use the Transitional Pain Service (TPS) model. Collecting data from the Acute Pain Service (APS), TPS and chronic pain clinic, our retrospective study seeks to elucidate risk factors associated with the development of chronic postsurgical pain (CPSP) and long-term opioid use and evaluate the efficacy of TPS in reducing opioid use in the Hamilton-Niagara Region. Very few studies have taken a comprehensive large-scale approach in assessing whether a TPS is more effective at getting patients off opioid analgesia (in comparison to patients in a control group with usual pain care), instead choosing to examine the incidence of and risk factors for developing CPSP. Results from our study will provide additional evidence for TPS as a standard of care for managing CPSP, decreasing opioid use and giving insight into the role of the pain clinician’s increasing role in
“Transitional Pain Service physicians have more training and experience in managing patients with complex pain problems. Our research seeks to ensure that the care and followup provided by theTPS is effective at reducing the amount of opioids prescribed postoperatively and reducing the number of patients on long-term opioids.” - Dr. James Paul
the opioid crisis. Implementation of a new hospital information system at HHS has resulted in logistical problems, requiring this project to be put on hold for the time being. Along with COVID-19, it has been difficult to implement a transitional pain tracking system at the pain clinic. We are making progress in reaching a solution. Dr. Madi Ali, who has been working with the TPS for the last five years, has agreed to work on this project in order to help track patients and collect study outcomes.

Institute for Pain Research & Care Seed Grants Opioid Reduction in Orthopedic Surgery (OREOS): A Feasibility Randomized Controlled Trial in Total Knee Replacement Patients Primary Investigator: Harsha Shanthanna, MD, PhD, FRCPC Start Date: 2022
Brief Overview and Progress to Date
“The trial aims to establish feasibility of a larger multi centred trial.” - Dr. Harsha Shanthanna
The main objective of this pilot trial is to assess the feasibility of a multicomponent pathway on patients having elective total knee arthroplasty, while the clinical objectives are to determine the effects of the pathway on opioid-free pain control, persisting pain and opioid use, functional knee outcomes, quality of life, and return to function. Patients in the intervention group will undergo a multicomponent intervention pathway that will be facilitated by an intervention coordinator linking each patient and their surgical/ perioperative team. We have completed recruitment and surgery of all study patients and we are working on data collection to ensure minimal loss to follow up.

Who is Susceptible to Developing CPSP? A HighThroughput Clinical Proteomics-Based Approach for the Prediction of Susceptibility Primary Investigator: Fei Geng, PhD Start Date: 2021
Brief Overview and Progress to Date Most, if not all, cases of CPSP include neuropathic pain (Gerdle and Ghafouri, 2020). The remainder having nociceptive (somatic or visceral) pain. The long-term goals of this research are to 1) define pain signatures to predict who is at risk for and who is resilient to developing chronic postsurgical pain from OA patients; 2) develop precision medicine to prevent or treat lasting pain from OA patients who are susceptible to chronic pain, potentially reducing reliance on opioids. The short-term goals are to 1) discover the pain signatures using high-throughput proteomic analysis of CPSP negative and positive plasma samples from OA patients after TKA; 2) validate the pain signatures using a separate validation cohort of OA patients. 3) clinical application of pain signatures in predicting chronic postsurgical pain for OA patients. Through this process we will identify and validate molecular signatures predictive of conversion from acute to chronic pain (pain signatures), which would provide new avenues to predict, prevent or attenuate chronic pain conversion, with a wide range of biochemical species that could provide a novel multi-molecular signature to chronic pain conversion.
Institute for Pain Research & Care / McMaster Institute for Research on Aging Catalyst Grants Persistent Post-Surgical Pain, Postoperative Cognitive Dysfunction, and Resilience in Older People Undergoing Elective Knee Surgery: A Mixed Method Project to Explore Associations and Underlying Mechanisms Primary Investigator: Maura Marcucci, MD, MSc Start Date: 2021
Brief Overview and Progress to Date The ArthroCaP project is a mixed methods study exploring the association between chronic post-surgical pain and cognitive decline in ≥50 years old patients who are undergoing total knee arthroplasty (TKA). The quantitative part is a cohort study where patients are longitudinally followed after surgery and assessed remotely upon their pain and cognitive function; it includes also the evaluation of biomarkers associated with pain and of development of cognitive dysfunction. For the qualitative part, a sample of study participants will be interviewed either before or after surgery upon their expectations and lived experience with surgery. The study was initially a substudy of the SPOC cohort study. To deal with the impact of the pandemic on
“Given the catalyst nature of the funding, we designed the study as a proof-ofconcept study expected to provide preliminary data and inform future observational and possibly interventional research involving post-surgical pain and perioperative neurocognitive disorders.” - Dr. Maura Marcucci
the pace of recruitment we amended the initial protocol to continue the study as a stand-alone study and to include also patients undergoing total hip arthroplasty. We closed the recruitment in the study and we are now completing the 6- and 12-month follow-up. We estimate to have 80 patients with complete data for the final analyses, with 30 patients included in the biomarker evaluation. We obtained extension of the project timeline. We plan to complete the analyses including the 12-month follow-up in June 2024.

Corticomuscular Coherence Brain-Computer Interface to Treat Chronic Neck Pain Primary Investigator: Aimee Nelson, PhD Start Date: 2022
Brief Overview and Progress to Date The project investigates the use of augmented reality which is a form of sensorimotor training in individuals with chronic neck pain. The goal of the research is to determine whether the effects of augmented reality can be enhanced by the delivery of repetitive transcranial magnetic stimulation (rTMS).
Forty participants
diagnosed with chronic neck pain will be recruited to create equally sized groups receiving real or placebo rTMS. Real or placebo rTMS will be delivered immediately prior to engagement in augmented reality.
The augmented reality involves neck
movements to targets presented in a systematically increasing excursion from center point. Each participant experiences 2 to 4 weeks (3-5 times/week) of placebo/real rTMS + augmented training. Dependent measures include corticomuscular coherence assessed before and the intervention, functional assessments and clinical outcomes related to pain and quality of life.
Institute for Pain Research & Care / McMaster Institute for Research on Aging Catalyst Grants A Feasibility Study to Assess the Added Value of Integrated Musculoskeletal BiofFeedback Device (IMBED) Combined with Neuromuscular Exercise and Education (GLA-Dtm) to Decrease Chronic Pain in Older Adults with Osteoarthritis Primary Investigator: Pasqualina Santaguida, PhD, PT, Stuart Phillips, PhD, MSc, BSc and Qiyin Fang, BSc, MSc, PhD, LEL Start Year: 2020
Brief Overview and Progress to Date The purpose of this catalyst research project will evaluate the feasibility and added value of a new technology called Integrated Musculoskeletal BiofFeedback Device (IMBED). We hypothesize when IMBED output is used while administering a specialized neuromuscular exercise and education program called Good Living with Arthritis in Denmark (GLA:D™) training for lower extremity osteoarthritis (OA), participant outcomes may be optimized. In Phase I we developed a software to integrate three well established technologies (digital mapping of chronic pain, EMG biofeedback for muscle activity and body motion sensors (IMU). User testing in Phase 1 will evaluate how IMBED output will be used and accepted by clinicians to adapt and improve training.

Engagement Annual Research Day “A patient once told me, ‘It’s hard to maintain personal relationships when it hurts to be hugged,’” said Dr. Tara Packham, discussing the functional consequences of allodynia. Dr. Packham was just one presenter amongst many at the Michael G. DeGroote National Pain Centre’s 2022 Annual Research Day. In addition to her presentation on allodynia, Dr. Packham, along with her colleague Dr. Lisa Carlesso, also provided an overview of the IMPRinT Lab and the importance of understanding pain with movement to optimize rehabilitation for musculoskeletal disorders. The 2022 Annual Research Day saw a return to an in-person format and was held in the Royal Botanical Gardens’ Café Annex, in Burlington, Ontario. In addition to Dr. Packham, presenters included Dr. Parminder Raina, of the Canadian Longitudinal Study on Aging (CLSA), who discussed building a population-based platform for research on aging and the opportunities for pain research within CSLA; Dr. Fei Geng, who discussed who is susceptible to developing CPSP; Dr. Yong Fang Zhu and Peter Kan of McMaster’s Singh Lab, who looked at computational analysis and modeling for neuropathic pain; Dr. PJ Devereaux, who provided an overview of the PVC-RAM-1 Trial and potential to improve post-hospital discharge pain after surgery. The 2023 Annual Research Day took place in May 2023. Subjects included statin-based muscular pain research, corticomuscular coherence brain-computer interface to treat chronic neck pain, treatment of chronic temporomandibular pain disorders: a clinical guideline; Opioid Reduction in Orthopedic Surgery (OREOS): a feasibility randomized controlled trial in total knee replacements; and a systematic review on postoperative pain and neurocognitive outcomes after non-cardiac surgery. The Institute’s Research Days serve as a wonderful way to introduce exciting new projects, as well as showcase interdepartmental collaborations at McMaster University, addressing the way that pain presents across a multitude of illnesses and following many medical procedures. 28

Partnerships & Collaborations Chronic Pain Centre of Excellence for Canadian Veterans Creating a national community of care for Veterans & families.
The Chronic Pain Centre of Excellence for Canadian Veterans is a research centre focusing on improving the well-being of Veterans with chronic pain. The Centre was announced in July 2019 and launched in April 2020 at McMaster University.
The Chronic Pain Centre of Excellence for Canadian Veterans (CPCoE) is honoured to have a collaborative relationship with the Michael G. DeGroote Institute for Pain Research and Care (IPRC). The IPRC participated heavily in the creation of the CPCoE and embedded our organization with a focus on the importance of working with people with lived experience. The CPCoE continues to uphold this principle of engagement and have recently adopted a new priority setting process. Using a process based on the work of the James Lind Alliance, the CPCoE solicited issues of importance from the Veteran and clinician stakeholders. The research team then explored these issues with the assistance of their Advisory Council for Veterans (ACV) and then prioritized these uncertainties that could be explored through research. Through this challenging but rewarding process, the ACV identified top research priorities for the CPCoE that will help set the scientific direction for their research over the next few years. In fiscal year 2022-2023, the CPCoE funded 15 new research projects bringing the total number of active research projects focused on chronic pain in Veterans to 30. To date, the CPCoE has partnered with a total of 26 different research institutions across Canada as well as in the United States and Australia. To accelerate the knowledge mobilization of research 30
findings, the CPCoE actively collaborates with funded researchers to support the development and dissemination of knowledge mobilization resources. The most successful knowledge mobilization endeavor of the year was the launch of the Most Painful Podcast which covers all aspects of chronic pain by presenting evidence-based information that provides better insight into chronic pain. The IPRC looks forward to working with the CPCoE to reach new milestones in the goal of keeping hope alive through Veteran-first chronic pain research.
Partnerships & Collaborations Chronic Pain Network: Knowledge Mobilization & Implementation Science
Scientific Director Dr. Norm Buckley and Person with Lived Experience and Advocat Therese Lane present a panel session at the Canadian Pain Society’s Annual Scientific Meeting in Banff, Alberta.
The Chronic Pain Network is a pan-Canadian research network with a specific focus on improving pain care, improving function, participation and quality of life for those affected by chronic pain, while alleviating the economic burden of pain over one’s lifespan. It was launched in 2016, as one of five networks in chronic disease funded through the Strategy for Patient-Oriented Research (SPOR), as part of the Canadian Institutes of Health Research (CIHR). In August 2021, CIHR announced a new competition for funding, open to the existing five Strategy for Patient-Oriented Research

The CPN was successful in its application for this funding and received $3,750,000, to be used over a four-year period. The new iteration of the Network has seen the formation and implementation of a new governance structure, with new committees and memberships. In 2022, the Network welcomed Brandon Van Dam as its new Managing Director, and has since grown to include Divya Kanwar Bhati as its Engagement Lead and 31

“With the Canadian Pain Care Forum we have had a series of talks focusing on healthcare professional curricula in the various professions - Psychology, Occupational therapy, Physiotherapy, Medicine, Nursing, Pharmacy, Chiropractic. This has led to not only greater awareness of projects underway, but also identified some gaps. As a result, The IPRC has entered into a partnership with the Canadian Psychology Association to create a series of teaching modules aimed at psychologists in independent practice to enhance their ability to work with people living with pain, and also to establish informal partnership with other professionals in their community to create ‘virtual’ interdisciplinary teams where these do not exist in other structures. This will launch in early 2024.” - Dr. Norm Buckley 34
