[Continuous Passive Motion in Orthopaedic Rehabilitation of the Shoulder Girdle - A Literature Survey].

BACKGROUND: Continuous passive motion (CPM) of the shoulder is predominantly used during postoperative rehabilitation of the shoulder girdle. It is often used after rotator cuff repair (RM suture). Incapacity to work and therapy of shoulder diseases cause significant costs for the healthcare system in Germany.

METHODS: In a literature analysis, studies and reviews of the CPM treatment in scientific databases were therefore identified and analysed with regard to the functional outcome particular after shoulder joint surgery. The quality of the studies was evaluated using the Cochrane Collaboration's Risk of Bias Tool.

RESULTS: After rotator cuff suturing, clinical studies have predominantly shown a faster improvement in pain level and shoulder mobility when using CPM treatment compared to other forms of treatment. In the case of frozen shoulder, only studies with the scope of CPM in conservative treatment could be identified. Here predominantly faster pain reduction could be observed. Studies addressing CPM in the therapy of Impingement of the shoulder, fracture of the humeral head or arthroplasty of the glenohumeral joint could not be identified. The health economic effects of CPM use are controversially discussed. In the available studies, equipment and other costs are assessed differently.

CONCLUSION: The analysed clinical studies showed overall positive effects, e. g. a faster improvement of pain level and shoulder mobility, in the postoperative therapy of the shoulder after rotator cuff repair as well as in the conservative therapy of shoulder stiffness for the CPM treatment compared to other forms of treatment. For other entities no meaningful studies are available in the literature to date. Since the health economic effects of the use of CPM have been discussed controversial so far, potential health economic benefits of the use of CPM treatment should be evaluated in future studies.
