Abstract:
A continuous passive motion leg exercise device for rehabilitation of knee motion, hip motion, and ankle motion after trauma or surgery is disclosed. The device includes an elongated base, a thigh support, a lower leg support pivotally connected to the thigh support, and a foot support pivotally connected to the lower leg support. The distal end of the lower leg support and foot support are mounted on a sliding bearing attached to the base. The thigh support is pivotally mounted to a thigh brace at one end. At the other end, the thigh brace engages a threaded drive screw extending from an enclosed motor assembly. The threaded drive screw is also enclosed except where the thigh brace extends through the enclosure. Movement of the thigh brace along the drive screw causes the thigh support, lower leg support, and foot support to move in a knee bending motion. The motor includes a motor cycling device which reverses rotation of the threaded screw.
