A continuous passive motion (CPM) machine is a motorized device that passively moves a joint through a pre-set range of motion. These devices may be used after surgery to reduce joint stiffness and improve range of motion.
A CPM machine may help you recover from surgery or injury in the following ways:
• The range of motion (ROM) of your arm or leg will increase. The CPM machine will flex (bend) your joint for you.
• Your muscles may get stronger more quickly.
• You may have less pain.
• You may have increased blood flow in your arm or leg.
