Frozen shoulder, also known as frozen shoulder, is a condition in which the passive movement of the humeral glenoid joint is limited and leads to reduced active shoulder mobility and pain. The typical frozen shoulder is divided into three periods: 1. Painful phase or freezing phase: The main symptom is pain and waking up at night, often relieved by rest but with increased stiffness. In this period, pain is the main symptom and you cannot move because of the pain. 2. Stiffness or freezing phase: This period is mainly characterized by a decrease in joint mobility, especially abduction and external rotation, with the typical symptom that the patient cannot do hair combing. 3, The remission period mainly shows the gradual recovery of joint mobility. The recovery time is directly related to the length of the pain period. Primary frozen shoulder is curable due to its progressive process. The following measures can be taken 1.Medication: Commonly used drugs include painkillers such as ibuprofen, diclofenac and other non-steroidal drugs, as well as traditional Chinese medicine to activate blood circulation and relieve pain, and topical creams. 2.Physical therapy: the most common hot compresses, ultrasonic therapy, acupuncture treatment, small acupuncture treatment, etc.; 3.Closure therapy: if the pain is obvious, you can inject steroid drugs in the joint cavity, which can effectively stop the pain. 4.Functional exercise: Proper functional exercise during the stiffness and remission period can shorten the recovery time. The more common exercises are hair combing, wall climbing, and of course, Taiji’s cloud hand is also a good choice. It should be noted that the focus of exercise is to reduce pain and resume exercise within the pain-free range to avoid new trauma. 5. Release under anesthesia: If the adhesions are serious, they can be released under anesthesia, but this is less effective for diabetic patients. Of course, frozen shoulder can also be caused by trauma, and this condition needs to depend on the trauma in order to recover. It should be noted that rotator cuff injury, visceral involvement pain, and shoulder pain caused by cervical spondylosis are also to be treated differently from frozen shoulder.
