“…At an early stage of SIS, which usually refers to stage I or early stage II, some nonoperative treatments may be effective, such as muscle exercises, for example, the training of the periscapular muscles (pectoralis minor, trapezius, serratus, and rhomboids) and strengthening of the rotator cuff (supraspinatus, infraspinatus, teres minor, and subscapularis), which functions as the stabilizer of the shoulder joint. Some investigators have also reported on many other nonoperative treatment methods, such as pulsed electromagnetic field therapy, 5 , 6 manual therapy, 7 – 10 kinesio taping therapy, 11 , 12 localized drug injection of corticosteroids, hyaluronate, or NSAIDs, 11 – 18 diacutaneous fibrolysis therapy, 19 specific exercise therapy that includes concentric and eccentric exercises for the scapula stabilizers and dynamic humeral centering and scapular stabilization exercises, 20 – 22 microwave diathermy therapy, 23 ultrasound therapy, 24 low-level laser therapy, 24 – 28 radial extracorporeal shockwave therapy, 29 and acupuncture therapy. 30 After these treatments have been performed, some patients may be relieved of SIS.…”
