NCT ID NCT07014098
First seen Jun 27, 2026 · Last updated Jul 29, 2026 · Updated 2 times
Summary
This study tests a robot-aided elliptical trainer designed to improve knee control in directions other than just bending and straightening. The goal is to reduce knee pain and improve function in 36 adults aged 45-85 with knee osteoarthritis. Participants will use the device to retrain how their knee moves, aiming to lower joint stress and ease discomfort.
