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 such as the hip, shoulder and elbow.
Uses 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. It is frequently recommended after knee joint replacement or knee cartilage repair surgery. Uses of the CPM are also reported in pediatric orthopaedic surgeries or injuries for maintaining hip and knee range of motion.[1] CPM was introduced in the early post-operative period and was combined with physiotherapy for maximum results. The device was well tolerated, without interfering with open wounds, nursing care or external fixation devices. [1]
CPM is also recommended for prophylaxis against thrombosis after total knee replacement, with some support from a small number of studies for its use. [2]
Mechanisms of action and timing[edit | edit source]
Joint stiffness after surgery or injury is reported to progress through four stages: bleeding, edema, granulation tissue, and fibrosis. [3] When applied during the first two stages, CPM can ensure the maintenance of normal periarticular soft tissue compliance and prevent the development of stiffness by helping pump blood and edema fluid away from the joint and periarticular tissues. [3] In other words, CPM prevents the initial or delayed accumulation of periarticular interstitial fluids. [3]
The duration of each session and the total period of CPM application remain controversial. [4]A Cochrane review suggests that short-term use of CPM offers greater short-term ROM benefits, but long-term improvements are yet to be demonstrated to justify its routine use. [5]
Clinical bottom line[edit | edit source]

CPM machines are most commonly applied to the knee, but there are versions for other joints.CPM is most commonly used after joint surgery to prevent joint stiffness complications and for prophylaxis against thrombosis. The duration of each session and the total period of CPM application remain controversial.
