Frozen Shoulder: The 3 Stages and How Physiotherapy Helps Each One

The Most Mismanaged Condition in Physiotherapy

In my clinical experience, frozen shoulder is the condition most frequently treated incorrectly. Patients are given aggressive stretching exercises during the inflammatory freezing stage — which worsens the pain and extends the recovery period significantly.

The key insight: frozen shoulder has three distinct stages, and the physiotherapy approach must match the stage. The wrong treatment at the wrong time does real damage.

Stage 1: Freezing (3-9 Months)

The shoulder becomes progressively more painful and stiff. This is an inflammatory stage. Pain is often severe, worse at night, and the shoulder hurts to move in any direction.

Correct physiotherapy approach: Pain management is the priority. Pendulum exercises (gravity-assisted, no active muscle work), gentle range of motion within the pain-free range, and education about positions to avoid. This is NOT the time for aggressive stretching — it will prolong the inflammatory phase.

Stage 2: Frozen (4-12 Months)

Pain begins to decrease but stiffness increases significantly. The shoulder is limited in all movements — reaching behind the back, overhead, and sideways are all restricted.

Correct physiotherapy approach: Progressive capsular stretching is now appropriate. Specific posterior and inferior capsule stretches, shoulder blade stabilisation exercises, and gradual loading to prevent muscle wasting.

Stage 3: Thawing (6-24 Months)

Gradual spontaneous improvement in movement. This stage responds best to physiotherapy intervention — targeted stretching significantly accelerates the recovery trajectory.

Correct physiotherapy approach: Progressive aggressive stretching of the inferior and posterior capsule, comprehensive strengthening, and functional restoration including overhead activities.

The Key Exercises (Stage-Appropriate)

Pendulum Exercise (All Stages): Lean forward supporting yourself on a table, let the affected arm hang freely, gently swing it in small circles. Uses gravity to distract the joint with zero active muscle tension — the safest possible movement for an inflamed shoulder.

Posterior Capsule Stretch (Stage 2-3): Lying on your back, bring the affected arm across your body with the elbow at shoulder height. Gently add pressure. Hold 30 seconds. The most important stretch for restoring internal rotation.

Why Early Diagnosis Changes Everything

The natural history without treatment is 2-3 years. With stage-appropriate physiotherapy started during freezing, most patients recover within 12-18 months with better final range of motion. If your shoulder has been progressively stiffening, book a consultation now — identifying the stage and starting the right treatment immediately changes your entire recovery trajectory.
