Continuous Passive Motion (CPM)

Introduction[edit | edit source]

Continuous Passive Motion (CPM) therapy uses machines to move a joint passively i.e. without the patient exerting any effort. A motorised device moves the joint repetitively to a set of number of degrees and movement speed, determined by the physiotherapist. CPM machines are most commonly applied to the knee, but there are versions for other joints as well.

Purpose of CPM[edit | edit source]

CPM is most commonly used after joint surgery to promote the recovery of normal joint range of motion (ROM) and thus, to prevent joint stiffness complications.
