Abstract
A semi-powered foot and ankle prosthesis () has a foot member () coupled to the ankle frame () and movable with respect to the ankle frame (). A linear actuator () is coupled to and between the ankle frame () and the foot member () to move the foot member () with respect to the ankle frame (). The linear actuator () has a drive motor (). A locking mechanism () selectively engages the drive motor () to selectively lock movement of the drive motor () to resist a force on the foot member () from backdriving the linear actuator ().
