Dr. Cynthia Long and I discuss the importance of statistics in chiropractic science. We talk about the role of statistics in research, when to involve a biostatistician into the research process, and the top statistical terms (such as power, effect size, significance, confidence intervals and many more). Dr. Long is Professor and Director of Research at Palmer College of Chiropractic, Davenport, IA, and Director of the Office of Data Management & Biostatistics (ODM) at the Palmer Center of Chiropractic Research (PCCR). She holds an M.S. degree in statistics from Iowa State University and a Ph.D. in biostatistics from the University of Iowa. Dr. Long joined the faculty of the PCCR at its inception in 1995 and contributed to developing PCCR’s research infrastructure, in particular creating the ODM to support the research design, data management and data analysis needs of PCCR research investigators. Since 2000, she has directed the ODM staff as data coordinating centers for 15 on-site, off-site and multi-site federally-funded clinical trials of chiropractic care. Dr. Long is the principal investigator of “Expanding Evidence-Based Clinical Practice and Research Across the Palmer College of Chiropractic”, a grant awarded by the National Center of Complementary and Integrative Health of the National Institutes of Health. She is also the director of Palmer’s MS in Clinical Research where she teaches 10 credit hours of biostatistics. She is on the editorial boards of JMPT and JCCA and has just completed a 3-year term as an elected member of the American Statistical Association board of directors.

Dr. Long mentioned the following paper in the show “Illustrating risk difference and number needed to treat from a randomized controlled trial of spinal manipulation for cervicogenic headache“.

Dr. Field and I discuss the clinical significance of patient reported outcomes and Care Response. Care Response is a free and pragmatic system to help practices gather and report clinical outcome and patient satisfaction information with minimal work from practice staff. Dr. Field is a clinical and NHS services lead at the Back2Health partnership providing community based MSK services to NHS and private patients. He has an active interest in research particularly relating to the impact of non-physical factors on recovery of chiropractic patients and the use of patients reports of changes in their health status (PROMs) and their experiences with care (PREMS).
Dr. Martin Descarreaux and I discuss his research regarding learning to perform chiropractic adjustments, neuromuscular responses following spinal manipulation and several other studies. Dr. Descarreaux graduated from the UQTR’s first cohort of the chiropractic program in 1998, and completed a PhD in kinesiology at the Université Laval 6 years later. He is now a full professor in the
Dr. Michele Maiers and I discuss the patient perspective in chiropractic clinical trials, integrative care and leveraging research to inform health care policy.
Dr. Alan Breen and I discuss spine dynamics and spine control along with quantitative fluoroscopy in chiropractic research and practice. Dr. Alan Breen graduated from the Canadian Memorial Chiropractic College in 1967, then travelled in North America, Australia and Europe before starting a part time teaching post at the Anglo-European College of Chiropractic (AECC) in Bournemouth UK in 1971, he established a practice in Salisbury in 1974, which continues. In 1986 Dr. Breen became Director of Research at AECC and focussed on musculoskeletal research and epidemiology, encouraging staff to undertake doctoral studies. In 1999 he became director of a new musculoskeletal research institute – the Institute for Musculoskeletal Research and Clinical Implementation, where he continues to work. Dr. Breen is also Professor of Musculoskeletal Research in the Faculty of Science and Technology at Bournemouth University.
Dr. Mitch Haas and I discuss the dose-response relationship between chiropractic and health outcomes as well as chiropractors in public health. Dr. Haas has been an integral member of the research division at the
James DeVocht, DC, PhD and I discuss research regarding the effect of chiropractic care on special operations forces reaction and response times, the biomechanical aspects of chiropractic care on patients, the cervical flexion-relaxation phenomenon and chiropractic treatment of temporomandibular disorders.
In this podcast episode, André Bussières DC, PhD and I discuss topics such as: research utilization and knowledge translation in chiropractic (the Know-Do gap) as well as professional behaviour change, and the Canadian Chiropractic Guideline Initiative.
