Episode Details

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.
