Frozen shoulder is clinically called adhesive capsulitis. This is a condition of unknown etiology characterized by gradually progressive, painful limitation of all joint movements with spontaneous restoration of partial or full range of motion over a period of time. Frozen shoulder affects 2% to 5% of the general population as a result of chronic inflammation of the capsular subsynovial layer leading to thickening, fibrosis, contracture, and loss of the normal axillary recess. It can be classified as primary (idiopathic) or secondary which is also divided into internal, external and systemic categories. Frozen shoulder can be divided into three phases, and the symptoms of this condition are pain in the shoulder joint when moving or pain during sleep, accompanied by stiffness and reduced range of motion, but also limited range of motion, especially external rotation. The condition manifests itself through a progressive loss of glenohumeral movements accompanied by pain. The diagnosis is based on medical history and physical examination and on the exclusion of other diagnoses. General conservative treatment consists of physical therapy, exercise, nonsteroidal anti-inflammatory drugs, and intra-articular steroid injections. Interventional procedures include hydraulic distension and manipulation under anesthesia, and surgical procedures include arthroscopic capsule release and open capsulotomy. Therapeutic exercise is the systematic performance or execution of planned body movements, positions or activities intended to repair or prevent damage, improve functionality, reduce risk, optimize the body system and improve fitness. Therapeutic exercises are an integral part of physical therapy often used in clinical practice to treat painful conditions of the shoulder, and are designed by rehabilitation professionals to achieve specific measurable outcomes. They are aimed at establishing normal kinematics by improving muscle activity, strength, flexibility and balance in the muscles.
