Ep21: Movement-based Strategies for Low Back Disorders Management with Dr. Tyson Beach

Dr. Tyson Beach is currently a teaching professor at the University of Waterloo, teaching courses on the biomechanics and assessment of human movement, exercise prescription, and low-back disorders. His previous research focused on quantitative motion analyses, prevention of work-related musculoskeletal disorders, and advancing fundamental knowledge of spinal mechanics, control, and injury causation. He also collaborates with other knowledge producers (researchers) and users (practitioners) to design, implement, and evaluate physical activity and exercise programs for workers and athletes.

In this episode, we discussed the literature on exercise interventions for low back disorders. Continuing the discussion from previous episodes (Ep19-20), we talked about factors affecting how people lift, movement-related strategies to manage low back disorders, and how we can encourage people to participate in physical activity.

Note that this episode presents perspectives in movement-based strategies for low back disorders through the lens of biomechanics and exercise. It is not an attempt to address the topic exhaustively, nor does it attempt to address all of low back disorders.

Paincast is dedicated to bringing together researchers, clinicians, and students to discuss topics related to pain and physiotherapy. The primary purpose is to facilitate knowledge translation and critical thinking. Some episodes posit themselves as more educational than others, and some more opinionated than others. The listener is encouraged to critically reflect on the content. While there is an effort to incorporate research evidence, and the topics are researched by the host (Tiffany), we recognize there is room for improvement and there is expertise in the community. As such, we invite constructive critique and that you inform us of any inadvertent errors, so that we may correct them.
