Physiotherapy is the main non-surgical treatment for frozen shoulder, and most people improve without surgery. Frozen shoulder (adhesive capsulitis) is a condition where the capsule around the shoulder joint thickens and tightens, causing pain and a steady loss of movement. It tends to pass through three stages over months, and the right physiotherapy depends on which stage you are in: easing pain and keeping what movement you have early on, then gradually stretching and strengthening as the shoulder starts to loosen.
This guide explains the stages, how frozen shoulder differs from other shoulder problems, what physiotherapy treatment involves at each stage, gentle exercises that are usually safe to try, and when to have your shoulder assessed.
What is frozen shoulder?
The shoulder joint sits inside a sleeve of connective tissue called the capsule. In frozen shoulder, that capsule becomes inflamed, then thickens and contracts, and bands of scar-like tissue form inside it. The joint has less room to move, so the arm gets stiff in every direction, not just one.
The two main symptoms are pain, which is often worse at night and can disturb sleep, and stiffness that makes everyday movements hard. Reaching behind your back to tuck in a shirt or do up a bra, reaching up to a high shelf, and turning the arm outward are usually the first things to go.
Who gets frozen shoulder?
According to the American Academy of Orthopaedic Surgeons (OrthoInfo), frozen shoulder is most common between the ages of 40 and 60 and occurs more often in women than in men. It is much more common in people with diabetes, and it is also linked with thyroid conditions. It can develop after the shoulder has been kept still for a while, for example after surgery, a fracture or another injury, which is one reason early, guided movement matters after any shoulder injury.
Often there is no clear trigger at all. Many people simply notice an ache that slowly turns into stiffness over a few weeks.
The three stages of frozen shoulder
Frozen shoulder is usually described in three stages. The time ranges below come from the American Academy of Orthopaedic Surgeons (OrthoInfo) and vary widely from person to person, so treat them as a general guide rather than a schedule.
Stage 1: Freezing
Pain builds gradually and the shoulder loses movement. This is often the most painful stage, and night pain is common. OrthoInfo describes it as typically lasting anywhere from 6 weeks to 9 months.
Stage 2: Frozen
Pain may start to ease, but the stiffness stays and daily tasks can be very difficult. OrthoInfo describes this stage as lasting about 4 to 6 months.
Stage 3: Thawing
Movement slowly returns. Getting back to normal or near-normal strength and motion typically takes anywhere from 6 months to 2 years, according to OrthoInfo.
The NHS puts it plainly: frozen shoulder can take months or years to get better, but the pain and stiffness usually go away eventually. The goal of treatment is to make that time more manageable, keep you using the arm, and support the return of movement.
Frozen shoulder or something else?
Not every stiff, painful shoulder is a frozen shoulder. A few other common problems look similar at first:
- Rotator cuff irritation or tear. Pain lifting the arm, often with weakness. You can usually still move the arm through more range when someone else lifts it for you. In frozen shoulder, the joint is stiff whether you move it or someone else does.
- Shoulder impingement or bursitis. A painful arc partway through lifting the arm, with easier movement above and below that point.
- Shoulder arthritis. More common in older adults, often with grinding and a gradual loss of movement over years rather than months.
- Pain referred from the neck. Shoulder or arm pain that changes with neck movement, sometimes with tingling into the hand.
Telling these apart matters because the treatment is different. Strengthening that helps a rotator cuff problem can aggravate a shoulder in the freezing stage, and stretching hard into a painful frozen shoulder can make it worse. A physiotherapy assessment sorts out which one you are dealing with.
How physiotherapy treats frozen shoulder
Physiotherapy is the treatment OrthoInfo describes as the primary recommendation for frozen shoulder, and the NHS notes that physiotherapy usually lasts at least 6 weeks. What the sessions involve changes with the stage.
In the freezing stage: calm the pain, keep what you have
When the shoulder is irritable, pushing hard into pain tends to backfire. Treatment focuses on easing pain and protecting the movement you still have. That usually means gentle range of motion work within comfort, hands-on techniques to ease muscle guarding around the shoulder and upper back, advice on sleeping positions and using the arm through the day, and pacing so you keep moving without flaring the shoulder up.
In the frozen stage: gradual stretching
As pain settles, the plan shifts toward slowly regaining range. Joint mobilization, where your physiotherapist moves the joint in specific directions, is combined with stretches you do at home. The stretches are held gently and progressed over weeks. The aim is steady gains, not forcing the joint.
In the thawing stage: restore strength and function
Once movement is coming back, strengthening the rotator cuff and the muscles around the shoulder blade helps you use the new range for real tasks: lifting, reaching overhead, carrying groceries, getting back to work or sport. Work-specific practice is added if your job involves overhead reaching or lifting.
Other options that may fit
Depending on your assessment, a plan may also include dry needling or IMS for tight, sensitive muscles around the shoulder, or registered massage therapy to ease tension through the neck, upper back and shoulder. These support the exercise part of the plan rather than replace it.
Some people also benefit from medical options such as anti-inflammatory medication, a steroid injection, or hydrodilatation, a procedure that stretches the capsule with fluid. Those are discussed with your family doctor or a sports medicine physician. Physiotherapy works alongside them, and your physiotherapist can help you decide when that conversation is worth having.
Gentle frozen shoulder exercises to try
These are common starting exercises. Move within a range that feels like a stretch or mild discomfort, not sharp pain, and stop any exercise that leaves your shoulder clearly worse for more than an hour or two afterwards. The NHS advises against strenuous exercises you have made up yourself, so if you are unsure, get them checked first.
- Pendulum swings. Lean forward with your good hand on a table and let the sore arm hang. Gently sway your body so the arm swings in small circles and back and forth. Let gravity do the work.
- Table slides. Sit beside a table with your forearm resting on a towel. Slide the arm forward along the table as you lean your body forward, then slide back.
- Wall walk. Face a wall and walk your fingers up it slowly, stopping at a comfortable stretch. Step a little closer as this gets easier.
- Outward rotation with a stick. Lie on your back with elbows bent at your sides, holding a broom handle or cane. Use the good arm to push the sore hand gently outward, keeping the elbow tucked in.
- Towel stretch behind the back. Hold a towel behind your back with the good hand above and the sore hand below. Use the good arm to gently draw the sore hand upward.
Short sessions spread through the day usually suit a frozen shoulder better than one long session. A warm shower or a heat pack beforehand can make the stretches more comfortable.
Living with a frozen shoulder day to day
Small changes make the months of recovery easier:
- Sleep. If you sleep on your back, a pillow under the sore arm can take strain off the shoulder. If you sleep on your side, lie on the good side and hug a pillow so the sore arm is supported.
- Dressing. Put the sore arm into sleeves first and take it out last. Front-opening tops are easier than pullovers during the stiffest months.
- Driving. Reaching for a seatbelt or shoulder checking can be awkward. Adjust mirrors carefully and make sure you can turn and steer safely.
- Winter in Edmonton. Scraping windshields and shovelling snow load the shoulder at the end of its range. Use a long-handled brush, push snow rather than throw it, and take breaks.
- Keep using the arm. Use it for light tasks within comfort. Avoiding the arm altogether tends to make stiffness worse.
When to have your shoulder assessed
Book an assessment if shoulder pain and stiffness have lasted more than a few weeks, if pain is waking you at night, or if you are losing the ability to reach behind your back or overhead. Getting help earlier means a plan matched to your stage, rather than guessing at exercises that may aggravate it.
See a doctor promptly if shoulder pain came on after a fall or a significant injury, if the shoulder looks deformed, if you have fever or redness around the joint, or if you have unexplained weight loss. Seek emergency care right away for shoulder or arm pain that comes with chest pain, shortness of breath or sweating, because that can be a sign of a heart problem.

Frequently asked questions
Can physiotherapy help a frozen shoulder?
Yes. Physiotherapy is the main non-surgical treatment for frozen shoulder. It helps manage pain, maintain and then regain movement, and rebuild strength, with the approach adjusted to the stage you are in. Results vary between people.
How long does a frozen shoulder last?
It varies widely. The NHS says it can take months or years to get better, and OrthoInfo notes it can take up to 3 years. Most people improve with relatively simple treatment such as physiotherapy and home exercise.
Should I rest or keep moving a frozen shoulder?
Keep moving it gently, within comfort. Complete rest tends to increase stiffness, but forcing painful movement can aggravate the shoulder, especially early on. A physiotherapist can show you how much is right for your stage.
Is heat or ice better for frozen shoulder?
Many people find heat more helpful before stretching, and the NHS suggests a heat pack for up to 20 minutes. Some prefer ice after activity if the shoulder feels sore. Use whichever eases your pain, and protect your skin with a cloth.
Do I need a referral for frozen shoulder physiotherapy?
No. In Alberta you can book physiotherapy directly without a doctor’s referral, although some insurance plans ask for one before they reimburse. Check your plan if you are unsure.
