Cadence: Steps to manage joint load in knee OA? An interview with Dr. Harvi Hart. Episode #447

Dr. Harvi Hart is a postdoctoral researcher at Western University in London, Ontario, funded by the Canadian Institutes of Health Research. Dr. Hart’s research focuses on identifying risk factors for knee osteoarthritis, both non-traumatic and post-traumatic osteoarthritis. Through better understanding these risk factors, Dr. Hart aims to develop new treatment approaches for managing knee OA. In this episode, Dr. Erin Macri asks Dr. Hart about her most recent studies looking at cadence and its possible role in joint loading and knee osteoarthritis.
