Continuous Passive Motion (CPM) devices for the shoulder are mechanical apparatuses designed to gently and consistently move the shoulder joint through a controlled range of motion. These devices typically cradle the arm and automatically flex and extend the shoulder within prescribed limits set by a medical professional. This controlled movement helps prevent stiffness and promotes healing following surgery or injury. A common example is its use after rotator cuff repair.
The therapeutic application of controlled, regular motion is understood to improve blood circulation, reduce joint inflammation, and minimize the formation of scar tissue, all of which contribute to a more rapid and complete recovery. Early mobilization facilitated by these devices can improve long-term joint function and potentially reduce pain. Historically, immobilization was the standard practice after shoulder surgery, but CPM therapy offers an alternative approach that addresses the complications associated with prolonged immobility.
