Assessment of a Microprocessor Ankle for Low Mobility Individuals with Amputation: Phase I



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. In particular, we are interested in seeing how this type of new device may benefit people who are rated as a K2 ambulator.
