Abstract

Purpose: To investigate the effects of electromyography (EMG) biofeedback on the muscle activity of the trapezius, shoulder pain, function, and range of motion (ROM) in patients with subacromial impingement syndrome (SAIS). Methods: Sixteen patients (9 males and 7 females) with SAIS participated voluntarily. The main outcome measures were muscle activity of the trapezius, shoulder pain (VAS), ROM, and the shoulder pain and disability index (SPADI). Exercises with EMG biofeedback consisted of shoulder flexion in a standing position, shoulder external rotation in a side-lying position, and shoulder horizontal abduction in a prone position. Post measurements were taken immediately after EMG biofeedback training. Results: Middle and lower trapezius activity, as well as ROM, was significantly increased by exercise with EMG biofeedback (p<0.05). In addition, VAS and SPADI scores significantly decreased post-EMG biofeedback training (p<0.05). Conclusion: EMG biofeedback intervention is an effective exercise for SAIS patients to restore activity of the middle and lower trapezius and to improve pain, shoulder function, and ROM.
