A leg suspension device is provided enabling rehabilitative exercise of the leg, and specifically enabling passive or active range of motion exercise of the knee or hip joint. The leg suspension device includes a bar having proximal and distal segments, and a fulcrum rotatably engaging the bar between the proximal and distal segments to permit rotation of the bar about the fulcrum in a vertical plane. Upper and lower leg cuffs are connected to the proximal and distal segments, respectively, suspending the upper and lower legs while isolating the knee joint. A base is provided to free-standingly support the device during use, or, alternatively, the device is adapted for affixing to an overhead anchor. For passive motion exercise, the thigh and ankle are suspended from the cuffs and the user drives rotation of the bar solely with the upper body muscles about the fulcrum in alternate opposing directions, causing alternate passive flexion and extension of the knee and hip joint. The same procedure is repeated for assisted active motion exercise, but the user drives rotation of the bar about the fulcrum with the upper body and leg muscles simultaneously. For independent active motion exercise, the user drives rotation of the bar about the fulcrum entirely with the leg muscles.
