A system for providing continuous passive motion of a subjects leg through hip extension and flexion. The system may have an actuator, a leg support member, a retention surface, and a base. The leg support member may be a support frame with a proximal member and a distal member. The subject places his/her leg on the leg support and the actuator provides a moment of force to the subjects leg to move the leg through the desired range of motion. The system may be controlled allowing the device to operate at different speeds and for different ranges of motion.
