The therapeutic role of motor imagery on the functional rehabilitation of a stage II shoulder impingement syndrome
Résumé
Purpose: Motor imagery (MI) has been used as a complementary therapeutic tool for motor recovery after central nervous system disease and peripheral injuries. However, it has never been used as a preventive tool. We investigated the use of MI in the rehabilitation of stage II shoulder impingement syndrome. For the first time, MI is used before surgery. Method: Sixteen participants were randomly assigned to either a MI or control group. Shoulder functional assessment (Constant score), range of motion and pain were measured before and after intervention. Results: Higher Constant score was observed in the MI than in the control group (p ¼ 0.04). Participants in the MI group further displayed greater movement amplitude (extension (p50.001); flexion (p ¼ 0.025); lateral rotation (p50.001). Finally, the MI group showed greater pain decrease (p ¼ 0.01). Conclusion: MI intervention seems to alleviate pain and enhance mobility, this is probably due to changes in muscle control and consequently in joint amplitude. MI might contribute to postpone or even protect from passing to stage III that may require surgery.
