The rehabilitation methods of biceps long head tendonitis include: general treatment, drug treatment, local closed therapy, physical therapy, trans-shoulder arthroscopic surgery and so on. 1. General treatment: once diagnosed, patients should pay attention to rest, local braking, and the earlier the start, the better the effect, in order to avoid biceps activity, if necessary, can use support. 2. Drug therapy: non-steroidal drugs are the first choice for clinical treatment of aseptic inflammation, such as diclofenac sodium capsules, aspirin, etc., which can play an anti-inflammatory and analgesic role. 3. Local closure therapy: when the effect of non-steroidal anti-inflammatory drugs is not obvious and the pain localization is clear, local closure therapy can be chosen, i.e., intratendon injection of steroid hormone in the local pain place to achieve the purpose of local anti-inflammatory. 4. Physiotherapy: For patients with limited shoulder joint activities, short-wave therapy, intermediate-frequency therapy, ultrasonic therapy and other physiotherapy can be used to control inflammation, relieve pain and improve the symptoms of limited activities. 5. Trans-acromial arthroscopic surgery: Trans-acromial arthroscopic surgery is performed through posterior, anterior and lateral approaches to the shoulder joint, operating in the glenohumeral joint and subacromial space respectively. Trans-acromial arthroscopic surgery has the advantages of small damage to soft tissues, low bleeding, quick recovery and small scar after surgery, and can be used for early functional exercises, etc. Once the diagnosis is confirmed, patients should be treated with short wave therapy, intermediate frequency therapy and ultrasound therapy to control inflammation and relieve pain and improve symptoms of limited movement. Once diagnosed, patients should be treated as soon as possible under the guidance of professional doctors to eliminate inflammation, which can restore shoulder joint activities as soon as possible and prevent recurrence and disability.
