What is CPM ?


Clinical application of CPM:
Continuous passive movement (CPM) is a new biological concept, which is to accelerate the healing and regeneration of articular cartilage and surrounding ligaments and tendons under the action of continuous passive movement. By simulating the natural movement of human body, it stimulates human’s natural resilience and plays a compensatory role in tissues. The knee joint and hip joint can move freely after recovery.
CPM provides gentle and continuous traction of the tissues around the joint to prevent fibrous contracture and release adhesion, thus maintaining range of motion. The relative movement of the articular surface and the periodic change of intraarticular pressure can be caused to accelerate the flow and renewal of the articular fluid. At the same time, the gentle alternating pressure and decompression of the articular cartilage can promote the exchange of the fluid in the matrix of the cartilage and the articular fluid, so as to maintain the nutrition of the cartilage and prevent its degenerative changes.
Compared with the general passive movement, CPM is characterized by long acting time, slow, stable and controllable movement, so it is safe and comfortable. Compared with active exercise, CPM does not cause muscle fatigue, can be continued for a long time, while the joint stress is less, can be used early in the case of joint injury or inflammation, and does not cause damage. Only early and correct use of the CPM machine can maximize the recovery of joint function and thus improve the quality of life of patients.
Clinical efficacy of CPM:
CPM is suitable for use immediately after surgery, such as open reduction fracture internal fixation, joint release and release of post-traumatic arthritis, extraarticular release of contracture, joint replacement, fracture and ligament reconstruction. CPM machine is considered to be a beneficial post-operative intervention to promote articular cartilage healing and regeneration. Specifically, they increase blood flow and nutrient circulation to the site of injury, while moving the limb or joint, preventing stiffness and pain, reducing pain and swelling, reducing the formation of scar tissue, and increasing range of movement and flexibility.
Helps prevent joint stiffness and increase range of motion.
Prevent the formation of motion-limiting adhesions.
Promote joint surface and soft tissue healing
Reduces edema and pain resulting in improved compliance with physical therapy and exercise
Stimulate cartilage healing and articular cartilage regeneration by increasing nutrient and metabolic activity through the synovial membrane
Less necrosis and increased tensile strength for tendon and ligament reconstruction
Through orthopedic surgeons and physical therapists, CPM devices will help heal damaged tissue and improve your recovery time

DCPM-E Lower limbs CPM is specially designed for the patients with the lower joints diseases to do Rehabilitation adjuvant therapy, because the lower limbs CPM can promote the joint fluid secretion and the absorption cycle of the joint fluid after the Trauma, it can also promote the regeneration of cartilage, prevent adhesion and ease the pain, the lower limbs CPM are applicable for the After-operation patients to do exercise.
