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 when the weather is colder; and along with the restricted movement can make even small tasks impossible. Certain movements or bumps can cause sudden onset of tremendous pain and cramping that can last several minutes.

This condition, for which an exact cause is unknown, can last from five months to three years or more and is thought in some cases to be caused by injury or trauma to the area. It is believed that it may have an autoimmune component, with the body attacking healthy tissue in the capsule. There is also a lack of fluid in the joint, further restricting movement.

In addition to difficulty with everyday tasks, people who suffer from adhesive capsulitis usually experience problems sleeping for extended periods due to pain that is worse at night and restricted movement/positions. The condition also can lead to depression, pain, and problems in the neck and back.

Risk factors for frozen shoulder include diabetes, stroke, accidents, lung disease, connective tissue disorders, thyroid disease, and heart disease.

Treatment may be painful and taxing and consists of physical therapy, occupational therapy, Chiropractic, medication, massage therapy, hydrodilatationor surgery. A doctor may also perform manipulation under anesthesia, which breaks up the adhesions and scar tissue in the joint to help restore some range of motion. Pain and inflammation can be controlled with analgesics and NSAIDs. The condition tends to be self-limiting: it usually resolves over time without surgery, but this may take up to two years. Most people regain about 90% of shoulder motion over time. People who suffer from adhesive capsulitis may have extreme difficulty working and going about normal life activities for several months or longer.
