Summary

The purpose of this study is to evaluate the performance of a powered ankle prosthesis capable of bidirectional control via neural recording and cutaneous stimulation, during free-space and walking tasks. This research aims to assess the sense of embodiment with the device, gait symmetry, and stability of a person with lower-extremity amputation walking with a powered ankle and their prescribed prosthesis. Findings from this study will inform future developments in bionic ankle design with optimal integration with the human body, with the goal of improving prosthetic integration into daily life.
