Frozen shoulder is a stubborn disease that plagues many office workers and hardcore mahjong players, and it’s hard to get rid of the root cause. For people who have been using computers and playing mahjong for a long time, they should pay attention to the following aspects to prevent frozen shoulder: 1. Do hot compresses from time to time. Use a warm water bag to warm up the shoulder area often to promote local blood circulation; 2. Avoid being sedentary. No matter how busy you are at work, you should take the time to stand up and walk around, so that your body can constantly change its posture, so that blood circulation is unimpeded; 3, remember to move around, stand up, move your waist, shake your arms, turn around, shake between, fatigue is swept away, the body will relax a lot; 4, do more gymnastics. At home, you may want to do gymnastics, yoga and fitness exercises, fully active muscles and muscles. Always remember that life is in motion; 5, more bending, more pounding around the shoulders. Do more bending and pound the shoulder area from time to time to relieve the fatigue of the shoulder area. This is different from rotator cuff injury (which is composed of ligaments and tendons around the shoulder joint and can stabilize the shoulder joint); it is easy to confuse frozen shoulder and rotator cuff injury clinically, and the treatment methods are different and the expected consequences are also different. If you have pain around the shoulder joint with obvious or not-so-obvious activity restriction, we recommend you to go to the orthopedic department of a regular hospital to get a clear diagnosis and then perform targeted treatment and exercise; it is better to move than to stay still after the diagnosis of frozen shoulder.
