Abstract
A knee exercise apparatus which provides for movement about three axes which correspond to and are coaxial with the knee joint axes of flexion/extension, tibial rotation and abduction/adduction. A specific arrangement for independently measuring torque and concomitant angular position changes about the knee joint axis of flexion/extension and tibial rotation as well as angular position changes about the axis of abduction/adduction is shown and described as are associated restraints to minimize superfluous movement about joints adjacent to the knee joint of interest.
