Continuous Passive Motion (CPM) devices are mechanical units designed to provide controlled, repetitive movement to specific joints. Typically used after surgery or injury, these devices passively move the affected joint through a prescribed range of motion. A common example is a CPM machine for a knee following surgery, which gently flexes and extends the joint to promote healing and prevent stiffness.
The controlled movement offered by these devices can be crucial for recovery. Regular, passive motion can improve blood circulation to the injured area, reduce swelling, and minimize the formation of scar tissue, ultimately leading to faster healing and improved range of motion. The development and increasing availability of these devices have significantly enhanced post-operative care and rehabilitation protocols. Their use can contribute to reduced hospital stays and improved patient outcomes.
