Active_comparator: Able-Bodied Participants

Able-bodied participants will complete a total of three study sessions. The three sessions include a clinical evaluation, gait biomechanics, and gait biofeedback for comparison with participants with DPN.

Experimental: Plantar Pressure Biofeedback Gait Training Followed by Propulsion Biofeedback Gait Training

Participants with DPN will complete a total of seven study sessions. The first three sessions include a clinical evaluation, gait biomechanics, and gait biofeedback for comparison with able bodied participants. Sessions four through seven involve two different biofeedback training sessions followed by a retention gait analysis test 24-48 hours after training. Participants in this study are are randomized to receive plantar pressure biofeedback gait training first and propulsion biofeedback gait training at least three weeks later.
