<strong>Frozen</strong> <strong>Shoulder</strong><br />

What is frozen shoulder?<br />

This is a condition in which the capsule of the shoulder joint becomes inflammed and<br />

thickened. This results in pain, stiffness and restriction of shoulder movement. This condition<br />

is also known as adhesive capsulitis. It is more common in women between the ages of<br />

40–65 years.<br />

What are the symptoms?<br />

You may have frozen shoulder if you experience pain and stiffness when:<br />

1. Lifting your arm, either straight out in front or sideways.<br />

2. Rotating your arm, such as when unzipping the back of your dress or reaching for objects<br />

in your rear pocket.<br />

3. Shampooing and dressing.<br />

4. Sleeping on the affected shoulder.<br />

What causes frozen shoulder?<br />

The exact cause is unknown. The condition has been linked to auto-antibodies that attack<br />

the joint capsule, resulting in inflammation, adhesion and eventual scar tissue formation. It<br />

may be triggered by injury (including surgery), degenerative changes in the joint, as well<br />

as viral illnesses. This condition is also more common in diabetics. Your shoulder may go<br />

through several stages as the scar tissue forms, with each stage lasting between three to six<br />

months:<br />

1. Freezing stage—you may experience ache and mild stiffness as the disease starts. Pain<br />

worsens as the condition progresses.<br />

2. <strong>Frozen</strong> stage—pain diminishes but stiffness increases. <strong>Shoulder</strong> movements can be<br />

severely restricted.<br />

3. Thawing stage—shoulder movement improves, and you will be able to do more<br />

activities. Complete resolution is the norm but up to 15% of patients may have remaining<br />

movement restriction or weakness.<br />

What will my doctor do?<br />

After a physical examination, an ultrasound scan and X-ray may be required to exclude<br />

other causes of pain. In the early stages, it may be difficult to tell it apart from other painful<br />

conditions affecting the shoulder.<br />

How is it treated?<br />

The disease will, unfortunately, have to run its course. The goal of treatment is to minimise<br />

pain and discomfort during the disease process and to restore full range of motion and<br />

strength by the end of its natural course. Your doctor may prescribe a course of antiinflammatory<br />

medication for symptom relief. Forceful manipulation should be avoided as<br />

this may worsen symptoms. Hydrodilatation of the joint may be required in severe cases.<br />

During this procedure, which is carried out under local anaesthesia, a small volume of sterile<br />

solution is injected into the joint to loosen the adhesions.<br />

To maintain shoulder function, you are encouraged to perform the exercises shown. Each<br />

exercise should be performed at least twice a day. Application of a warm towel for 5–10<br />

minutes prior to exercise will reduce the discomfort. Exercise both shoulders, so that you can<br />

also maintain movement in the healthy shoulder. If there is increased pain after exercise, ice<br />

the painful part for 5-10 minutes.<br />

What is my prognosis?<br />

Many people with frozen shoulder regain full use of their shoulder after the condition has<br />

run its course. However, this may take 6–18 months from the onset of symptoms, and there<br />

may be some remaining pain and stiffness. Recurrence, either in the same shoulder or the<br />

other side can happen.<br />
