*The participant’s actual 10-m overground walk test speed was higher than the speed tested on the treadmill. Participant #01’s actual overground speed was 1.16 m/s, but this participant was not safe walking at this speed on the treadmill. Participant #07’s speed was 1.72 m/s, but this speed was beyond the capabilities of the electromechanical actuator used for this study.

†Participant #04 typically used a foot-up brace. Participant #05 used a custom brace that supported frontal plane motion.
