Frozen Shoulder: Stages, Exercises That Help and What to Avoid

Frozen shoulder moves through freezing, frozen and thawing stages. Learn which exercises suit each stage, what to avoid, and when to see a doctor.

Frozen shoulder (adhesive capsulitis) is a painful, stiff shoulder that typically moves through three stages: freezing, frozen and thawing. Gentle, pain-limited movement helps in the early stages, stronger stretching suits the later stages, and most people improve over one to three years. Exercise aims to keep the movement you have and rebuild what you lose, without inflaming the joint.

This is general information. A shoulder that is stiff after a fall or injury, or that comes with chest or neck symptoms, needs a medical assessment first.

What is frozen shoulder and who gets it?

The tissue lining the shoulder joint (the capsule) becomes inflamed, thickened and tight. You lose movement in all directions, especially turning the arm outwards (as if reaching to the car seat behind you) and lifting it overhead.

It tends to appear in middle age and later. It is more common in people with diabetes. A meta-analysis estimated that about 13 percent of people with diabetes have frozen shoulder, well above the rate in the general population, and the condition can be more resistant to treatment. Diabetes is common in Malaysia, so many adults over 40 are in this at-risk group. If you have diabetes and your shoulder is stiffening, tell your doctor early. Our article on exercise for type 2 diabetes covers the wider picture.

A recent period of shoulder immobility, for example after surgery or a stroke, is another commonly described trigger.

What are the three stages?

These ranges come from commonly cited descriptions, and individual courses differ. Sources give somewhat different ranges, so treat them as rough guides. Some people skip clear stages, and some have lingering stiffness beyond two years.

Which exercises help in the freezing stage?

Keep to comfortable movements. Do them 3 to 4 times a day for short periods rather than once for a long session.

1. Pendulum swing. Lean forward, supporting yourself with the good hand on a table. Let the sore arm hang loose. Gently sway the body so the arm swings in small circles, 10 circles each way.
2. Table slide. Sit at a table with the sore forearm on a towel. Slide the towel forward as you lean in, then return. 8 to 10 repetitions.
3. Supported arm raise. Lie on your back. Clasp your hands and use the good arm to lift the sore arm as far as comfortable. Hold 5 seconds, 8 repetitions.
4. Shoulder blade squeezes. Sit tall, draw the shoulder blades back and down for 5 seconds, 8 to 10 repetitions. This keeps surrounding muscles active.

Stay in the zone of mild discomfort, around 3 to 4 out of 10. A warm shower beforehand helps many people. Avoid sleeping on the sore side, and use a pillow to support the arm.

What exercises suit the frozen and thawing stages?

As pain settles, you can stretch more firmly.

1. Wand or towel flexion. Hold a stick or broom handle with both hands, and use the good arm to push the sore arm overhead. Hold 20 to 30 seconds, 3 to 5 times.
2. Towel external rotation. Hold a stick with elbows bent at your sides, and use the good arm to push the sore hand outwards. Hold 20 seconds, 5 repetitions.
3. Cross-body stretch. Pull the sore arm gently across the chest with the opposite hand, 20 seconds, 3 times.
4. Band row and external rotation. Once movement is better, strengthen with a light band. 2 sets of 10 to 12 repetitions, 3 days a week. The resistance band row is a good start, and our shoulder mobility after 50 article has more progressions.
5. Wall slide. Place forearms on a wall and slide upward as far as comfortable.

For adults 40 and above, 2 to 3 stretching sessions a day is a realistic target during the frozen stage, and strengthening 2 to 3 days a week in the thawing stage.

What does the evidence say about exercise and other treatment?

A Cochrane review looked at manual therapy and exercise for adhesive capsulitis, including 32 trials with about 1,800 participants, and concluded that the evidence on specific techniques is limited and of low quality. A later systematic review with meta-analysis also found benefit from combining manual therapy and exercise. No single technique clearly beats the others, and in practice an individualised programme with education works well.

A doctor may also offer pain relief, a corticosteroid injection into the joint, or in persistent cases other procedures. These decisions depend on your stage, diabetes status and preferences. Exercise sits alongside them.

What should I avoid?

• Forcing the arm into a deep stretch while it is still very painful.
• Heavy lifting overhead, or heavy bench or shoulder pressing during the freezing stage.
• Immobilising the arm completely in a sling for comfort. It makes stiffness worse.
• Sudden jerks, yanking with a pulley, or having someone push the arm hard.
• Taking pain medication and then exercising far beyond what you could tolerate without it.

Common mistakes

• Doing one large, hard session and flaring the shoulder for a day.
• Treating pain as the only problem. Some stiffness is expected, so keep stretching often.
• Ignoring the neck and upper back. A tight thoracic spine limits overhead reach. See mobility for hips and back for a gentle routine.
• Assuming it will fix itself and doing nothing for a year.

When should I see a doctor?

See a doctor if:

• shoulder pain follows a fall or accident;
• pain is severe at rest and not easing after a couple of weeks;
• you have fever, redness or a hot, swollen joint;
• you have numbness or weakness in the arm or hand, or neck pain spreading down the arm;
• you have pain on the left side with chest tightness, sweating or breathlessness, which may be heart-related and needs emergency care.

Check with a doctor before exercising if you have heart disease, uncontrolled blood pressure or poorly controlled diabetes. See when to get medical clearance.

Where does this fit in the bigger picture?

Frozen shoulder is one of several joint problems that limit movement and independence. Our exercise for limited mobility hub and the strength training for longevity hub show how to rebuild once the shoulder is moving again. If you are caring for a parent with a frozen shoulder, see ageing parents.

How do I adapt daily tasks in Malaysia while it heals?

Ordinary tasks become hard. Hanging washing on a low line, reaching a high kitchen cabinet, fastening a seatbelt or reaching behind you for the car seat can all hurt. Use a lower rack, keep common items between waist and chest height, and let the good arm do the overhead reach. When pulling on a baju or kurung, put the sore arm in first. Lifting a heavy rice pot, a gas cylinder or a big bag of groceries from the pasar with the sore arm should wait.

Try your stretches after a warm shower in the morning, when the muscles are more relaxed. Air-conditioned rooms can stiffen a sore shoulder, so keep it covered. If you work at a desk, bring the keyboard and mouse close so the elbow stays near your side.

Key takeaways

• Frozen shoulder has three stages, and it usually improves over one to three years.
• Early on, use gentle, short, pain-limited movements several times a day.
• Later, stretch more firmly and add band strengthening.
• Avoid forced stretching in the painful stage, long immobilisation and heavy overhead lifting.
• People with diabetes are at higher risk. See a doctor for injury, fever, arm numbness or chest symptoms.
