Assessment of a Hybrid Pump for Vacuum Suspension of Prosthetic Sockets for Persons With Lower Limb Loss to Characterize the Effects of Added Movement on Socket-reaction Torques
Sponsor: VA Office of Research and Development
Summary
Prostheses can be suspended from the amputated limb using a variety of techniques, such as straps and suction. Suspending the prosthesis by creating a vacuum between the prosthetic socket and limb using a pump has benefits over other techniques including improved limb health and mobility. A new pump design will be tested by prosthesis users in the laboratory to verify its functionality during walking.
