Frozen shoulder: symptoms, assessment and physiotherapy

Frozen shoulder, also called adhesive capsulitis, is a condition associated with shoulder pain and restricted movement. Similar symptoms can have other causes, so diagnosis should not come from a self-test. Physiotherapy may be part of management, with the approach tailored to the stage, irritability, function, and medical context.

People often call any painful, stiff shoulder a frozen shoulder. Clinically, that label is more specific. A proper assessment matters because rotator cuff problems, arthritis, injury, neck-related symptoms, and other conditions can also affect shoulder movement.

What makes frozen shoulder different from general shoulder pain?

Frozen shoulder is characterised by a pattern of pain and substantial restriction of both active and passive shoulder movement. The exact diagnosis requires clinical context, not just one movement such as reaching behind the back.

If stiffness followed trauma, surgery, or another medical problem, tell the clinician because that changes the context.

What a physiotherapist may assess

Assessment may include the history, onset, daily limitations, sleep impact, shoulder movement, strength where appropriate, and whether neck or neurological features need consideration. The physiotherapist may also ask about medical conditions such as diabetes because research shows an association between diabetes and frozen shoulder.

An association does not mean diabetes is the cause in a particular person.

What physiotherapy may involve

Management can include education, activity advice, and exercises or manual approaches selected to match the person's presentation. The intensity of rehabilitation should not be copied from a generic "unfreeze your shoulder" routine. A very irritable painful shoulder may need a different approach from a later, less painful but stiff presentation.

When another medical opinion may be useful

A physiotherapist may recommend medical review when the presentation does not fit an uncomplicated musculoskeletal pattern, when pain is severe or unexplained, or when other investigations or treatment options need discussion. Sudden major weakness after injury, systemic illness, or other urgent symptoms should not be managed through self-treatment content.

What to note before a physiotherapy assessment

Bring the story of the problem rather than a self-diagnosis. Note when it started, what was happening around the onset, what has changed since then, which daily activities, work tasks, or sport are affected, and what you have already tried. Mention previous injury or surgery and any medical instructions that could change rehabilitation. If you already have relevant reports or imaging, take them with you.

Also decide what improvement would matter to you. "Less pain" may be one goal, but function is often easier to make specific: walking to the market, using stairs, sitting through work, sleeping, lifting a child, returning to exercise, or getting back to another activity that matters to you. Clear goals give the assessment and follow-up something meaningful to measure.

How to judge online advice on this topic

Be cautious when an article gives everyone the same diagnosis, exact exercise dosage, fixed recovery date, pain threshold, or promise of prevention. Those details can sound useful while ignoring age, diagnosis, surgery, medical conditions, severity, goals, and how the person responds. Strong evidence can guide care without turning a population-level recommendation into a personal prescription.

Prefer sources that state what is known, what is uncertain, and who the recommendation applies to. Use online information to prepare better questions, not to replace assessment. If a symptom pattern is changing quickly, follows major trauma, or includes features that may need urgent medical care, choose the appropriate medical route rather than trying to solve it from search results.
