Continuous passive motion orthopedic device

A continuous passive orthopedic device for the exercising of limbs for therapy, rehabilitation or healing, including a compact drive mechanism which permits the device to be located solely within the confines of a standard hospital bed and permits the leg of a patient to be supported in a near horizontal position when it is straight. Control of the angle of flex is accomplished through a control instrument located at the knee joint. The control instrument includes a pair of adjustable indicators which can be moved to the desired end points of flexure. The device includes a narrow base plate which allows the patient to keep his legs closer together during use. Also included is a mechanism whereby the ankle can be flexed between preset angles simultaneously with the flexing of the knee.
