Continuous Passive Motion
Also written as: CPM — Continuous Passive Motion
Mechanical device that moves joints through range of motion without patient effort following surgery.
Full Definition
Continuous Passive Motion (CPM) refers to a motorized device that passively moves a joint through a controlled range of motion without active muscle contraction from the patient. CPM machines are commonly prescribed following knee, shoulder, or elbow surgeries to maintain joint mobility, reduce stiffness, and promote healing. The device settings include range of motion parameters and cycle speed, which are gradually progressed based on healing protocols. Insurance coverage for CPM rental often requires specific documentation of medical necessity.
Usage
Usage note: Capitalize abbreviation; use specific degree measurements when documenting settings.
