Pressure-based auditory feedback was employed to facilitate a gait modification in the gait lab and at home in individuals with medial knee osteoarthritis (OA). We evaluated subjects’ responses immediately and three weeks post training, as well as their responses after a three-week washout from feedback. Our primary variable of interest was the knee adduction moment (KAM), a surrogate measure of compartmental knee loads. We hypothesized that after training subjects will walk with a lower KAM. A reference group was included to ensure any observed changes in KAM were due to gait retraining and not simply due to footwear and/or interaction with the feedback system.
