Frozen shoulder is one of the more frustrating shoulder problems because it often arrives with no injury and leaves slowly. It is also far more common in women than men. Forza Physiotherapy was recently quoted in Canadian Living's article on frozen shoulder and why so many women are affected. This guide covers what frozen shoulder is, how it usually behaves, and how frozen shoulder physiotherapy in Vancouver fits in.

What frozen shoulder is

Frozen shoulder, also called adhesive capsulitis, is a condition where the capsule around the shoulder joint becomes inflamed, thickened and tight. The result is pain and stiffness that limits how far the shoulder can move, in every direction, whether you move it yourself or someone else moves it for you.

That last point matters. Many shoulder problems, such as a rotator cuff issue, make it hard to lift your arm yourself, but someone else can still move it for you. With frozen shoulder, the joint itself is stiff, so it does not move far either way. HealthLink BC's guide to frozen shoulder describes it as stiffness, pain and limited movement that usually develops slowly.

Why it affects so many women

Frozen shoulder is most common between about 40 and 70, and it affects women more often than men, particularly around and after menopause. The exact reasons are still being studied, which is part of why the Canadian Living piece focused on the question.

Other things linked with a higher chance of frozen shoulder include:

• Diabetes and thyroid conditions

• A period of keeping the arm still, after surgery, a fracture or an injury

• Having had frozen shoulder in the other shoulder before

The point about keeping the arm still is the useful one for everyday life. HealthLink BC warns that keeping an arm in a sling or immobilized for too long can lead to stiffness and even frozen shoulder. If you have had a shoulder or wrist injury, follow your doctor's advice, but ask about when to start moving again.

The stages of frozen shoulder

Frozen shoulder is usually described in three overlapping stages. Not everyone moves through them neatly, and how long each one lasts varies a lot from person to person.

Freezing. Pain builds, often worse at night and when lying on the affected side, and movement starts to reduce.

Frozen. Pain often eases somewhat, but stiffness is at its worst. Reaching behind your back, overhead or out to the side becomes hard.

Thawing. Movement gradually starts to come back.

HealthLink BC notes that frozen shoulder tends to develop slowly and go away slowly, over the course of a year or more. We are not going to promise you a faster timeline, and you should be cautious of anyone who does.

How frozen shoulder physiotherapy helps

Here is the honest caveat: physiotherapy does not "unfreeze" a shoulder in a session or two, and aggressive stretching in the painful stage can make things worse. What physio does is match the treatment to the stage you are in.

In a painful, irritable shoulder, the focus is on calming things down: gentle movement within comfort, advice on sleep positions, pain management strategies and keeping the rest of your arm and upper back strong. As the shoulder settles, the work shifts towards progressive range-of-motion exercises and strengthening, so you use the movement you have and build on it.

Physiotherapy also works alongside medical treatment. Some people are offered a corticosteroid injection by their doctor, and physio is often used around it. Your physiotherapist will refer you back to your doctor if anything does not fit the picture of frozen shoulder.

What to do at home, and what to avoid

A few things are worth doing before your first appointment:

• Keep using the arm for light everyday tasks within comfort, rather than resting it completely

• Try heat before gentle movement if it helps the shoulder feel looser

• Try a pillow under the affected arm at night

• Write down which movements are hardest; it helps your physiotherapist track change

And a few to avoid: forcing the arm through sharp pain, long periods in a sling unless your doctor has asked for one, and copying a stretching routine from the internet without knowing which stage you are in.

Frozen shoulder FAQ

What is the main cause of frozen shoulder?

The main cause of frozen shoulder is not fully understood. It involves inflammation and thickening of the capsule around the shoulder joint. It is more common in people aged 40 to 70, in women, in people with diabetes or thyroid conditions, and after a period of keeping the arm still following injury or surgery.

Does physiotherapy help frozen shoulder?

Physiotherapy is a common part of frozen shoulder treatment, used to manage pain and to restore movement and strength as the shoulder allows. The approach changes with the stage: gentle and pain-guided early on, then more progressive stretching and strengthening as it settles. It is often combined with care from your doctor.

Should I rest a frozen shoulder?

No, complete rest is not usually recommended for frozen shoulder. Keeping the arm still for long periods can add to stiffness. Gentle, comfortable movement and light daily use are usually better, while avoiding forcing the shoulder through sharp pain. Your physiotherapist can set the right level for your stage.

How do I know if it is frozen shoulder or a rotator cuff problem?

The main difference is passive movement. With frozen shoulder, the shoulder is stiff whether you move it or someone else moves it for you. With many rotator cuff problems, lifting is painful or weak but the joint can still be moved by someone else. An assessment with a physiotherapist or doctor will tell the difference.

Do I need a referral to see a physio for frozen shoulder?

No, you can book physiotherapy at Forza without a doctor's referral. Some extended health plans ask for one before they reimburse, so check your policy. If you have seen your doctor already, bring any notes or imaging reports to your first appointment.
