Measure
Gait Training With Exoskeleton Resistance
Participants will complete 20-30 minutes of ankle resistance training on each visit. This will involve walking on a treadmill with stance phase ankle resistance and biofeedback. Ankle resistance and biofeedback: An ankle exoskeleton will provide stance phase resistance and a plantar pressure biofeedback system will encourage late stance push-off.
