What is CPM?

Continuous passive motion (CPM) is a method usually carried out with patients who have been through limb or joint surgery or are in the treatment process. This therapy involves the continuous movement of the joints to ensure the effective healing process. CPM devices are usually used during the initial period of rehabilitation following a surgical procedure or trauma.

How does one use CPM?

CPM is usually administered by a nurse or a helper at home. The device is carefully attached to or worn over by the patient and then a system operates the device. The device ensures constant movement of the joint. The movements may be rhythmic or irregular but usually start from a small range of motion and increase as the treatment increases.

What are the effects of CPM?

The main aims are to control post-operative pain, reduce inflammation, provide passive motion in a specific plane of movement, and protect the healing repair or tissue. CPM is carried out by a device, which continuously moves the joint in a controlled range of motion. The exact range depends on the joint, but in most cases the range of motion increases over time. CPM devices are extremely efficient in managing pain. The continuous movement of a joint results in the release of synovial fluid which in turn increases the delivery of nutrients to the joint. This reduces inflammation and also decreases the intensity of the pain. CPM effectively pumps fluid away from the joints thus preventing accumulation of oedema in the joint. It is of maximum benefit after a few hours and days of the surgery.

Who uses CPM?

Individuals who have just been through joint or tissue surgeries are one of the major recipients of this therapy. Also people suffering from arthritis and other joint related problems use CPM for reducing pain as well as enhancing mobility.
