A continuous passive motion (CPM) device operating with a 120-degree range of motion typically refers to a machine used in physical therapy to improve joint mobility after surgery or injury. This type of device gently and repetitively flexes and extends the joint through a prescribed arc, in this case, up to 120 degrees. This controlled movement can be applied to various joints, such as knees, shoulders, or elbows, depending on the specific device and patient needs. For instance, following knee replacement surgery, a CPM machine might be employed to promote circulation, reduce stiffness, and prevent the formation of scar tissue.
Facilitating controlled and consistent joint movement offers several potential advantages in post-operative rehabilitation. It may assist in minimizing pain and swelling, improving range of motion, and accelerating the healing process. The historical development of these devices stems from the recognition that early mobilization plays a critical role in successful recovery after joint surgery or trauma. The precise angle of flexion, such as 120 degrees, is carefully determined by medical professionals based on individual patient conditions and the specific joint involved.
