This study is being done to conduct a preliminary investigation into a new prosthetic microprocessor controlled ankle, called the Damping, Stiffness, and Repositioning (DSR) ankle. Participants will visit the Shirley Ryan AbilityLab 10-16 times over 9 weeks, each visit lasting approximately 3 hours, to perform a series of walking and mobility tests with both their own prosthetic ankle and the DSR ankle.

Shirley Ryan AbilityLab, ranked “No. 1 Rehabilitation Hospital in America,” has a network of locations and partners with others to expand care into more communities.
