Frozen shoulder is also known as frozen shoulder because of the loss of shoulder joint pain and movement due to soft tissue lesions around the shoulder. It is a chronic and specific inflammatory disease of the shoulder capsule and its surrounding ligaments, tendons and bursae that is characterized by pain in the shoulder, which gradually worsens, especially at night, and restricts the movement of the shoulder joint, and becomes increasingly aggravated, gradually relieving after a certain point, until it finally recovers completely. Frozen shoulder is a chronic injury-related inflammation of the shoulder joint, causing pain and impaired movement, commonly known as “fifty shoulder” or “frozen shoulder”. For patients in the acute stage, rehabilitation treatment should focus on reducing pain, relieving muscle spasm, and accelerating the absorption of inflammation, and non-steroidal drugs and physical therapy can be used. Patients should actively do active exercise training while receiving passive treatment. Usually, when patients exercise on their own at home, they rotate the shoulder joint and “draw circles” with the big arm. This can increase the impact of the humeral tuberosity on the acromion and aggravate the development of inflammation. The correct way to exercise is to lean your upper body forward 30-45°, point your fingers to the ground and rotate the shoulder joint naturally, doing a “pendulum-like” movement to increase the joint gap and avoid bone to bone impact or friction within the joint, which is more conducive to the recovery of frozen shoulder.
