Yale-led study finds wearable sensors match motion capture for gait tracking in knee osteoarthritis

Yale-led researchers demonstrated that foot-mounted wearable sensors can match motion-capture systems for gait tracking in knee osteoarthritis patients, according to findings published in JMIR Formative Research. The study, involving international collaborators, showed wearable sensors achieved near-equivalent accuracy in measuring walking speed and other gait parameters without requiring laboratory-grade motion-capture equipment, potentially enabling remote patient monitoring and home-based assessment.
