Mechanically and Physiologically Optimizing Prosthetic Elevated Vacuum Systems in People with Transtibial Amputation

Join Dr. Steve Gard, editor-and-chief for the Journal of Prosthetics and Orthotics, as he chats with Joan Sanders, PhD, about her pilot study on the mechanical and physiological effects of EV when determining the optimal vacuum pressure for people with transtibial amputations. The two discuss the motivation behind the pilot study, primary findings and surprises, and clinical takeaways.
