Altered kinematics and neuromuscular control in off-axis knee motions have been reported in patients with knee osteoarthritis (OA), which are associated with excessive knee loading and the progression of knee OA. However, traditional rehabilitative treatments for people with knee OA and existing exercise equipment often focus on sagittal plane movement. Probably due to the technical limitations, there is a lack of convenient and effective equipment\u002Fmethod to train patients with knee OA in off-axis (frontal and transverse) planes.\n\nThe purpose of this study is to use a robot-aided elliptical training device to measure knee neuromechanical properties and to improve neuromuscular control in off-axis knee motions, aiming for joint de-loading and pain reduction for individuals with knee OA.",[60],"Osteoarthritis of Knee",[62,63,64,65,66,67],"knee osteoarthritis","robot-assisted","neuromuscular training","knee biomechanics","knee symptoms","evaluation-based training strategy","NOT_YET_RECRUITING","2026-04-17",{"date":71,"type":72},"2026-04-21","ACTUAL",{"date":74,"type":54},"2026-05-01",{"date":76,"type":54},"2030-01",{"name":5,"class":6}]
