Frozen Shoulder (Adhesive Capsulitis).
What is frozen shoulder?
Frozen shoulder, also known as adhesive capsulitis, is a painful and debilitating condition of the shoulder joint characterised by stiffness, limited range of motion, and pain that can significantly affect daily activities such as dressing, sleeping, and reaching.
The underlying pathology is fibrosis and contracture of the glenohumeral joint capsule — the fibrous envelope surrounding the shoulder joint — which progressively thickens, loses its normal folds and elasticity, and adheres to the humeral head, restricting the shoulder's range of motion in all directions. External rotation is typically the first and most severely affected movement, followed by abduction and internal rotation. In a fully frozen shoulder, range of motion in all planes is substantially reduced and the characteristic "capsular pattern" of restriction is present.
Primary versus secondary frozen shoulder
This is a clinically important distinction. Primary frozen shoulder — also called idiopathic adhesive capsulitis — develops without a clear precipitating cause and is associated with systemic metabolic conditions. Secondary frozen shoulder develops as a consequence of a known cause, most commonly prolonged immobilisation following shoulder surgery, fracture, or rotator cuff injury.
Frozen shoulder can be caused by a variety of factors, including injury, surgery, prolonged immobility, or certain medical conditions such as diabetes or thyroid disorders. The association with diabetes is particularly strong — people with diabetes have two to four times the risk of developing frozen shoulder compared to the general population, and diabetic frozen shoulder tends to be more severe, more bilateral, and less responsive to treatment. Thyroid disorders, Parkinson's disease, cardiovascular disease and prolonged immobility are also associated risk factors. It is more common in individuals aged 40 to 60 years and is more prevalent in women than men.
The three stages
Frozen shoulder evolves through three characteristic stages. During the freezing stage, which can last 2 to 9 months, the shoulder becomes increasingly stiff and painful. In the frozen stage, which can last 4 to 12 months, the pain may decrease but the shoulder remains stiff. Finally, in the thawing stage, which can last 5 to 24 months, the shoulder gradually regains range of motion and function. The entire process can take 1 to 3 years to complete.
Understanding which stage a patient is in fundamentally changes the physiotherapy approach. Aggressive stretching and mobilisation in the freezing stage — when inflammation is active — can worsen pain and potentially accelerate fibrosis. The frozen stage is the primary window for more active manual therapy and stretching. The thawing stage is when the most rapid range of motion gains occur and rehabilitation effort is most rewarded.
A note on prognosis and the natural history
It is worth being honest about what the evidence says about frozen shoulder prognosis. While the condition is often described as self-limiting — eventually resolving spontaneously — the reality is more nuanced. Studies with long follow-up periods show that a significant proportion of patients — up to 40% — have persistent restriction and functional limitation at seven to ten years. This challenges the reassuring "it will eventually get better on its own" narrative and makes active treatment a more compelling option than watchful waiting alone.
How can physiotherapy help?
Physiotherapy is an effective treatment option for frozen shoulder and can help reduce pain, increase range of motion, and improve overall function. The physiotherapy approach is stage-specific.
In the freezing stage, the goal is pain management rather than aggressive range-of-motion work. Gentle pendulum exercises, submaximal pain-free range-of-motion movements, postural education, and activity modification reduce the pain burden without provoking the inflammatory phase. Patient education about the condition — understanding the staging, prognosis and what to expect — is particularly valuable during this distressing early phase.
In the frozen stage, more active manual therapy is introduced — sustained capsular stretching, end-range glenohumeral mobilisation and posterior capsule stretching are the primary interventions with the strongest evidence for improving range of motion. The posterior capsule is consistently the tightest structure in frozen shoulder and is the most important target for sustained stretching.
In the thawing stage, progressive strengthening restores the rotator cuff and scapular muscle strength that has been lost during the prolonged period of restricted movement, and range of motion is progressively challenged toward full recovery.
Manual therapy including gentle mobilisation and stretching techniques improves joint mobility and reduces stiffness. Exercise therapy with a specific program improves strength, flexibility and range of motion. Education on proper posture, body mechanics and home exercises maintains progress between sessions.
Real time ultrasound assists in retraining rotator cuff activation where pain-related inhibition has disrupted normal muscle recruitment. Clinical Pilates can improve shoulder mobility and stability, as well as enhance overall posture and body awareness, with a personalised program including scapular stability, shoulder mobility and overall body alignment exercises. Dry needling of the periscapular and rotator cuff musculature assists with pain management and muscle guarding reduction.
For patients whose frozen shoulder developed following a workplace injury or motor vehicle accident, WorkCover and CTP funded physiotherapy is available.
