A Wearable Musical Feedback System for Medical Knee Osteoarthritis: Feasability and Biomechanical Effects

This publication investigates the feasibility and biomechanical impact of a wearable musical-feedback system designed to counter medial knee osteoarthritis. The system leverages Moticon wireless sensor insoles (such as OpenGo and ReGo) to capture real-time plantar pressure and center of pressure (CoP) data at a high sampling rate. By translating these metrics into real-time auditory adjustments (musification), the device dynamically alerts users to modify their walking patterns. The Moticon sensor insoles directly influenced the results by providing the high-fidelity biomechanical data necessary to guide participants to successfully medialize their CoP, thereby reducing the knee adduction moment (KAM) and mitigating medial joint overload without altering natural walking speed or cadence.
