Frozen Shoulder Physiotherapy: 3 Clinical Stages, Spencer Technique and Capsular Stretches
In short
Adhesive capsulitis causes progressive shoulder stiffness and sleep-disrupting night pain, particularly in individuals with diabetes or thyroid conditions. Learn the clinical staging criteria, safe manual therapy protocols like the Spencer technique, and home stretches.

Pathology of Adhesive Capsulitis: Why the Shoulder Freezes
Adhesive capsulitis is an inflammatory condition characterized by progressive fibrosis, thickening, and contracture of the glenohumeral joint capsule, particularly the coracohumeral ligament and the rotator interval.
The joint volume, normally 15 to 30 millilitres of synovial fluid, shrinks to 5 millilitres or less. In India, frozen shoulder exhibits a high prevalence among individuals with type 2 diabetes mellitus, where chronic tissue glycation stiffens collagen cross-links in the capsule.
The 3 Clinical Stages and Staging-Specific Therapy Rules
Treatment that accelerates healing in stage 3 can cause intense agony and setback if applied in stage 1. Matching physiotherapy to the stage is paramount.
| Stage | Duration | Key Clinical Signs | Physiotherapy Treatment Directive | |
|---|---|---|---|---|
| Stage 1: Freezing (Painful) | 2 to 9 months | Severe constant ache; sleep disrupted; pain precedes stiffness | Gentle pain-free pendulums, modal analgesia, sleep positioning; NO aggressive stretching | |
| Stage 2: Frozen (Stiff) | 4 to 12 months | Pain stabilizes; profound loss of external rotation and abduction | Low-load prolonged capsular stretching, grade II-III joint mobilizations, Spencer technique | |
| Stage 3: Thawing (Recovery) | 12 to 24+ months | Minimal pain; progressive spontaneous return of range of motion | End-range stretching, rotator cuff strengthening, functional scapular coordination |
The Spencer Technique: 7-Step Shoulder Mobilization Protocol
The Spencer technique is a time-tested manual therapy series designed to improve shoulder range of motion through systematic joint mobilization and muscle energy techniques (MET).
- Glenohumeral Extension with Elbow Flexion: The patient lies on their non-affected side. The therapist gently stabilizes the scapula and extends the humerus backward.
- Glenohumeral Flexion with Arm Extended: Moving the arm forward and overhead within tolerable limits.
- Glenohumeral Circumduction with Compression: Gentle clockwise and counter-clockwise circular movement with gentle joint compression to nourish articular cartilage.
- Circumduction with Traction: Repeating circles with gentle axial distraction to open the tight capsule.
- Abduction and Adduction with Internal Rotation: Mobilizing the arm across the body and upward.
- Internal Rotation with Arm Behind Back: Mobilizing the hand behind the waist to restore reach-behind-back function.
- Glenohumeral Distraction with Scapular Glide: Manual separation of the humerus from the glenoid cavity.
Safe Daily Home Exercises for the Stiff Phase
Once out of the acute inflammatory freezing phase, perform these exercises twice daily.
- Codman Pendulum Swings: Lean forward supporting your unaffected arm on a sturdy table. Let your painful arm dangle limp like a ragdoll. Use gentle hip momentum to sway the arm in small circles without activating shoulder muscles.
- Supine Cane External Rotation: Lie on your back holding a walking cane or umbrella with both hands. Keeping your affected elbow tucked against a small towel roll at your side, use your healthy hand to gently push the cane outward.
- Overhead Pulley or Wall Crawls: Stand facing a wall and gently walk your fingers upward like a spider, stepping closer to the wall as your arm elevates.
Sleep Positioning to Prevent Agonizing Night Pain
Night pain is the most distressing symptom of frozen shoulder. Never sleep directly on the painful shoulder. If sleeping on the opposite side, place a thick pillow across your chest to support your affected arm, preventing it from drooping forward into painful adduction and internal rotation. If sleeping on your back, place a folded towel under your affected elbow to keep the humerus aligned with your torso.
Frequently Asked Questions
Why is frozen shoulder so common in people with diabetes in India?
Elevated blood glucose levels cause advanced glycation end-products (AGEs) to accumulate in collagen fibres. This promotes excessive cross-linking, making the shoulder joint capsule thick, stiff, and prone to severe chronic inflammation.
Should a physiotherapist aggressively force my arm up under pain?
No. The obsolete practice of forcefully breaking adhesions through agonizing manipulation causes capsular micro-tearing, secondary muscle guarding, and prolonged inflammation. Gentle low-load prolonged stretches yield superior long-term range without trauma.
How do I know if it is frozen shoulder or a rotator cuff tear?
In a rotator cuff tear, active movement is limited by weakness, but a therapist can usually move your arm through a fuller range passively. In frozen shoulder, both active and passive motion are equally blocked by mechanical capsular tightness, especially in external rotation.
