Rehabilitation for frozen shoulder is not a single exercise prescription. It is a process of matching education, movement, loading and—where appropriate—manual therapy to pain irritability, functional goals and response over time.
Exercise and mobilisation may improve pain, movement and function, but trials use highly variable programmes and certainty is often low. More treatment is not automatically better. Dosage should be tolerable, measurable and adjusted from the patient’s response.
Start with irritability and function
A highly irritable shoulder may react badly to repeated end-range loading. Early priorities often include explanation, sleep and activity modification, comfortable movement and maintaining function. As pain settles and stiffness becomes more dominant, longer-range mobility work and progressive strengthening may become more appropriate.
Exercise categories
- Supported mobility: pendulum, table or wall-assisted movements that reduce load.
- Assisted range: active-assisted elevation and external rotation within an agreed tolerance.
- Isometric loading: low-load cuff and deltoid effort when movement is painful.
- Progressive strengthening: graded resistance for the cuff, scapular muscles and functional patterns as irritability allows.
- Whole-person activity: maintaining general physical activity and confidence rather than protecting the entire upper limb indefinitely.
Manual therapy
Joint mobilisation and soft-tissue techniques may provide short-term symptom or movement changes for some people. The evidence does not support presenting a specific technique as a necessary mechanical correction. Manual therapy is best treated as an optional component that creates a window for movement, exercise or valued activity—not as the whole programme.
What does “dosage” mean?
Dosage includes range, force, repetitions, hold time, frequency and recovery between sessions. Trials are too heterogeneous to establish one optimal formula. A practical prescription therefore defines a starting dose and a response rule. Mild, short-lived discomfort may be acceptable; substantial night-pain escalation, loss of function or a reaction persisting into the next day suggests that range, force or volume should be reduced.
Measure and progress
Choose outcomes that matter: sleep, dressing, grooming, reaching, work or sport, alongside pain and reproducible movement measures. Progress one variable at a time. Improvement can mean greater range at the same symptom level, the same task with less symptom response, or increased load without a prolonged flare.
What the evidence does not establish
It does not identify a universally superior exercise, mobilisation grade or visit frequency. Stage labels are useful shorthand, but individual irritability and trajectory should guide decisions. Apparent short-term gains should not be confused with proof that adhesions have been permanently altered.
