Condition guide

Frozen shoulder (adhesive capsulitis)

A condition in which the shoulder first becomes painful and then gradually seizes up. It usually gets better on its own, but this can take months or even years. With the right exercise and treatment, you can get through this period more comfortably.

What is it?

The connective tissue that surrounds the shoulder joint, called the capsule, thickens, becomes inflamed and shrinks. The space for movement inside the joint narrows. The result: pain, and a clear restriction in lifting the arm, reaching behind you and turning the arm outwards.

Turning the arm outwards is usually the most restricted movement. Brushing your hair, putting on a jacket and fastening a clasp or belt behind your back become difficult. The pain is often worse at night, and lying on that side becomes difficult.

Who gets it?

  • People aged 40–60; more common in women
  • Much more common, and longer-lasting, in people with diabetes
  • Thyroid disease (an underactive or overactive thyroid)
  • Keeping the arm still for a long time after surgery, a fracture or an injury
  • Stroke, Parkinson's disease and heart disease

Some people who have had it in one shoulder may develop it in the other shoulder over the years.

Three stages

How long each stage lasts varies from person to person; it is usually longer in people with diabetes.

1 · Freezing

Painful stage

About 2–9 months

Pain gradually increases, especially at night. Range of movement starts to decrease.

2 · Frozen

Stiffening stage

About 4–12 months

Pain may ease, but the shoulder becomes very stiff. Everyday tasks are hardest during this stage.

3 · Thawing

Recovery stage

About 5–24 months

Movement slowly returns. Some people may be left with mild restriction for a long time.

Diagnosis and treatment

The diagnosis is usually made from an examination: the shoulder is equally restricted whether you lift your arm yourself or someone else lifts it for you. An X-ray, ultrasound or MRI is not needed to make the diagnosis, but one may be requested to rule out other causes such as osteoarthritis or a tear.

  • Physiotherapy and exerciseThis is the foundation of treatment. In the painful stage, the focus is on gentle movements within the pain-free range; in the stiffening stage, it moves to stretching and joint mobilisation. Regular exercise at home is very important.
  • Pain controlHeat and painkillers recommended by your doctor make it possible to exercise.
  • Cortisone injection into the jointIt can clearly reduce pain within a few weeks, especially in the early, painful stage. Its effect is mostly short-term; whether to have one is your doctor's decision.
  • HydrodilatationFluid is injected into the joint to stretch the shrunken capsule.
  • Surgical optionsIf months of treatment bring no improvement, manipulation under anaesthetic or keyhole (arthroscopic) capsular release may be considered.

Exercises at home

A warm-up and five commonly used exercises

Do these exercises only until you feel a mild stretch; do not push into sharp pain. Keep the dose low in the painful stage. Work out with your physiotherapist which exercises suit your stage.

Heat

Warm the shoulder first

Before exercising, place a warm towel or a hot-water bottle on your shoulder for 10–15 minutes. This relaxes the muscles and makes the movements easier. Put a thin cloth in between to protect your skin.

1–2 times a day, 20 minutes at most
Pendulum

Pendulum

Lean on a table with your good hand and bend forwards. Let your painful arm hang loosely and swing it in small circles. Move the arm by gently rocking your body, not by using the arm muscles.

10 circles clockwise, 10 anticlockwise
Finger walk

Wall finger walk

Stand facing the wall, an arm's length away. Walk your fingers up the wall like a spider, pause for a few seconds where you feel tension, then slowly come back down.

10 reps, 1–2 times a day
Towel stretch

Towel stretch

Hold a towel behind your back with both hands: your good arm on top, your painful arm below. Use your good arm to slowly pull the towel upwards, letting the painful arm slide up your back.

Hold for 10–20 seconds, 5 reps
Cross-body stretch

Cross-body stretch across the chest

Reach your painful arm across the front of your chest towards the opposite shoulder. With your other hand, press gently just above the elbow and draw the arm towards you.

Hold for 15–20 seconds, 5 reps
External rotation

External rotation with a stick

Lie on your back or stand. Keep the elbow of your painful arm tucked in at your side and bent to 90 degrees. Hold a stick with both hands; use your good arm to push the stick so that the forearm of your painful arm turns outwards.

Hold for 15–20 seconds, 5 reps

Video

Exercise videos for each stage

Step-by-step exercise programmes for each stage of frozen shoulder, from the YouTube channel of US physical therapists Bob Schrupp and Brad Heineck.

Stage 1: Freezing (painful phase)

Gentle exercises to keep the shoulder moving without increasing pain.

Stage 2: Frozen (stiffening phase)

Stretching and mobilisation exercises to increase range of movement.

Frequently asked questions

Does frozen shoulder go away on its own?

It usually gets better on its own, but this can take months or even years; the condition typically lasts 1–3 years. Some people may be left with mild restriction for a long time. With the right exercise and treatment, you can get through this period more comfortably.

Should I move my painful shoulder?

Yes, but without forcing it. In the painful stage, the focus is on gentle movements within the pain-free range; in the stiffening stage, it moves to stretching and joint mobilisation. Do the exercises only until you feel a mild stretch; do not push into sharp pain.

Do I need an MRI for frozen shoulder?

The diagnosis is usually made from an examination: the shoulder is equally restricted whether you lift your arm yourself or someone else lifts it for you. An X-ray, ultrasound or MRI is not needed to make the diagnosis, but one may be requested to rule out other causes such as osteoarthritis or a tear.

Do cortisone injections work?

A cortisone injection into the joint can clearly reduce pain within a few weeks, especially in the early, painful stage. Its effect is mostly short-term, and whether to have one is your doctor's decision. The foundation of treatment, however, is physiotherapy and regular exercise.

When to seek help right away

Shoulder pain is not always frozen shoulder. See a doctor without delay in these situations:

  • If the pain started after a fall or a blow
  • If you have sudden weakness, numbness or tingling in your arm
  • If your shoulder is red and swollen and you have a fever
  • If you have unexplained weight loss or severe night pain that does not ease with rest
  • Especially if left shoulder pain comes with chest pain, shortness of breath or sweating (it may be your heart; call 112)
