Patients suffering from frozen shoulder can play badminton, which can effectively treat or prevent frozen shoulder. Frozen shoulder is a chronic injury that causes aseptic inflammation of the tendons, bursa and ligaments of the shoulder joint, and adhesions with the surrounding tissues, causing pain and limited movement of the shoulder joint. If you are in acute attack, avoid playing badminton and other activities with large amplitude, pay attention to rest and promote the absorption of inflammation. During the remission period, you can play badminton to promote the release of adhesions around the joint through maximum flexion, abduction, internal rotation, internal retraction and posterior extension of the shoulder joint. Avoid excessive movements that exceed the load of the joint to prevent muscle ligament strains or aggravate rotator cuff injuries, and strengthen local hot compresses and massage to help relieve symptoms.
