Currently, there are mainly surgical and non-surgical treatments for rotator cuff injuries. Surgical treatment is mainly for rotator cuff injuries with large tears, while non-surgical treatment is mainly for rotator cuff injuries with small to medium tears. The main methods of traditional treatment for rotator cuff injury are local closure, Chinese medicine, non-steroidal anti-inflammatory drugs, acupuncture, moxibustion and tui na, etc. For rehabilitation treatment of rotator cuff injury, clinically common methods include combination of ultrashort wave, microwave, medium frequency electrical stimulation, shock wave, direct current ion introduction, joint loosening, exercise training, etc. As a non-surgical method more important treatment means, it can relieve pain faster, improve joint mobility, and has significant clinical efficacy. The rotator cuff is an important part of the body, mainly composed of the supraspinatus, infraspinatus, teres minor and subscapularis muscles, and plays an important role in maintaining the stability of the shoulder joint. Rotator cuff injuries are mainly caused by vascular ischemia, rotator cuff degeneration, trauma, impingement syndrome and other factors. If a patient has a rotator cuff injury, the main manifestations are joint pain, dysfunction and limited movement. Since the rotator cuff assumes the role of maintaining the stability of the rotational axis on the scapular and articular surfaces, and is also an important role in the mechanical balance of the shoulder joint, it must be given effective treatment for rotator cuff injuries.
