Abstract
A continuous passive motion (CPM) apparatus mobilizes the knee joint of a patient's leg. In order to achieve total extension of the leg, the CPM apparatus pauses each time the extension end position is reached. A neuro-muscular stimulator (NMS) is enabled to provide stimulation to the patient's quadriceps muscle to effect a total extension of the leg. At the end of the pause interval, the NMS turns off, and the CPM resumes motion.
