Lower leg kinematics when kam reduced after pressure-based auditory feedback training in knee osteoarthritis

Pressure-based auditory feedback training (PBFT) from a clinically-appropriate wireless shoe insole was employed to facilitate the skill acquisition for subjects with medial knee osteoarthritis (OA). The goal of the PBFT was for subjects to learn a gait modification that targets knee load distributions in the frontal plane by medially shifting their foot center-of-pressure. The initial kinetic responses and kinematic strategies that subjects implemented to attain the medial shift during PBF were assessed. They reduced knee adduction moment (KAM) and knee adduction angle during midstance, and altered their shank and rearfoot kinematics in the sagittal and transverse plane.
