Early prevention of frozen shoulder can effectively improve the shoulder symptoms of patients. Office workers, due to long-term ambulatory work, shoulder muscles and ligaments are in a state of tension, so frozen shoulder is not uncommon, so the prevention of frozen shoulder is very critical. 1. Correct bad posture: For people who often work with their shoulders in abduction, they should pay attention to adjusting their posture to avoid chronic strain and accumulative injury caused by long-term bad posture. 2. Strengthen functional exercises: such as wall climbing exercises, posterior hand pulling exercises, external rotation exercises and bladder shaking exercises. Pay special attention to the movement of the joints, you can often play taijiquan, taiji sword, gateball, or at home to carry out double arm suspension, using tensioners, dumbbells and two-handed swing, but pay attention to the amount of exercise, so as not to cause damage to the shoulder joint and its surrounding soft tissues. 3, pay attention to the cold and warmth: cold moisture constantly invade the body, can make muscle tissue and small blood vessels contraction, muscle contraction for a longer period of time, can produce more Metabolic products, such as lactic acid and pain-causing substances gathered, so that muscle tissue stimulation and spasm, long caused by fibrous degeneration of muscle cells, muscle contraction dysfunction and cause a variety of symptoms. Therefore, it is important to pay attention to the cold and warmth in daily life, especially to avoid the shoulder from getting cold.4. Note: Diseases related to secondary frozen shoulder, such as cervical spondylosis, diabetes, shoulder and upper limb injuries, thoracic surgery and neurological diseases, should be closely observed by people suffering from the above diseases to see if they produce shoulder pain symptoms and if the range of motion of the shoulder joint is reduced, and active and passive exercises of the shoulder joint should be carried out. 5. For patients who already have frozen shoulder: In addition to active treatment of the affected side, prevention of the healthy side should be carried out. Some studies have shown that in 40% of patients with frozen shoulder 5-7 years after the disease, frozen shoulder will occur on the opposite side; in about 12% of patients, frozen shoulder will occur on both sides. Therefore, preventive measures should be taken on the healthy side to improve the working condition of white-collar workers.
