what is a cpm machine
Continuous Passive Motion (CPM) is a postoperative rehabilitation therapy designed to aid in patient recovery after joint surgery, soft tissue surgical procedure or trauma. The treatment method has been practiced for more than 30 years. After extensive joint surgery patient attempts at joint flexion can cause considerable pain, dissuading the patient from effective joint motion. Failure to achieve proper rehabilitative flexion can lead to stiffening of the tissue around the joint.
