An elbow continuous passive motion (CPM) machine is a physiotherapy device used primarily after surgery or injury to gently and continuously move the elbow joint without effort from the patient.
Elbow CPM Machine
Elbow CPM machines are used as an adjunct to traditional physiotherapy to:
- Prevent Joint Stiffness: The main purpose of the machine is to prevent the formation of scar tissue and joint contractures (stiffness) that can occur after surgery or periods of immobilization.
- Improve Range of Motion (ROM): By providing controlled, repetitive movement (flexion and extension, and sometimes pronation/supination), it helps maintain and gradually increase the elbow's functional range of motion.
- Reduce Pain and Swelling: The continuous motion helps pump blood and edema (fluid) away from the joint area, reducing inflammation, swelling, and post-operative pain.
- Accelerate Healing: Enhanced blood circulation to the affected area promotes the delivery of essential nutrients and oxygen, which supports the healing process of articular tissues, ligaments, and tendons.
- Decrease Complications: Early and controlled mobilization can reduce the risk of complications such as delayed recovery and the need for further procedures to address stiffness.
Elbow CPM machines are often prescribed in physiotherapy protocols for patients recovering from specific conditions or procedures, including:
- Post-surgical rehabilitation: Especially after arthroscopic contracture release surgery.
- Intra-articular fractures: After open reduction and internal fixation (ORIF).
- Prosthetic elbow joint replacement.
- Release of extra-articular adhesions.
- Chronic stiffness and arthritis management.
