Abstract
We present a novel swing phase control module for powered transfemoral prostheses based on minimum jerk theory. The control module allows physiologically appropriate swing movement at any walking speed, regardless of the stance controller action. Preliminary validation in a transfemoral amputee subject demonstrates that the control module provides physiological swing timing, without speed or patient-specific tuning.
