Periarthritis, also known as frozen shoulder in clinical terms, is generally caused by chronic strain leading to aseptic inflammation of tendons, ligaments, and joint capsules around the shoulder joint. This results in symptoms of pain and limited mobility, particularly pain at night, with both active and passive movements likely to be restricted. In such cases, besides rest and physiotherapy, and the use of topical non-steroidal anti-inflammatory and analgesic medications, it is also essential to engage in appropriate functional exercises for the shoulder joint to avoid with the goal of restoring its function. For instance, the shoulder joint should perform active bending, stretching, and abduction movements, as well as circumduction movements of the shoulder joint. These exercises aim to restore the function of the ligaments and tendons surrounding the shoulder joint.
