Periarthritis (Frozen Shoulder)
Frozen shoulder, medically referred to as adhesive capsulitis, is a disorder in which the shoulder capsule, the connective tissue surrounding the glenohumeral joint of the shoulder, becomes inflamed and stiff, and grows together with abnormal bands of tissue, called adhesions, greatly restricting motion and causing chronic pain. It has an incidence of 2.4/1000 per year. Adhesive capsulitis is a painful and disabling condition that often causes great frustration for patients and caregivers due to slow recovery. Movement of the shoulder is severely restricted. Pain is usually constant, worse at night, and along with the restricted movement can make even small tasks impossible. Certain movements can cause sudden onset of tremendous pain and cramping that can last several minutes.
The following signs and symptoms :
