Following shoulder reduction (the emergency procedure to relocate the humeral head into the glenoid socket), the immediate priority is protecting the damaged static stabilizers — the torn labrum and inferior glenohumeral ligament — while preventing the stiffness that develops from prolonged complete immobilization.

Immobilization Position: Traditionally, the arm was immobilized across the body in a standard sling (internal rotation). However, MRI studies demonstrating superior anatomical positioning of the torn Bankart labrum in external rotation have led to increasing use of external rotation braces, which hold the arm slightly away from the body. Our therapists will discuss the optimal immobilization position based on your specific Bankart lesion and the treating physician's preference.

Restricted Active Range of Motion: During the sling phase, we prescribe careful elbow flexion/extension, wrist circles, and gentle pendulum exercises to maintain circulation and prevent elbow and wrist stiffness — without applying any rotational or abduction stress to the healing shoulder.

Axillary Nerve Assessment: An axillary nerve stretch injury occurs in 5–35% of anterior dislocations, producing deltoid weakness and numbness over the outer shoulder (the 'badge' area). We conduct a careful neurological assessment and monitor recovery throughout rehabilitation. Axillary nerve injuries are almost always temporary neuropraxia that resolves within 3–6 months.

Patient Education on Instability Positions: The most important educational message in Phase 1 is identifying and avoiding the instability position — arm abducted to 90° and externally rotated. This is the position in which re-dislocation most easily occurs and must be strictly avoided for the first 6 weeks.

Once the acute phase has passed and initial labral healing has commenced, we progressively mobilize the shoulder while simultaneously building the rotator cuff muscles — the primary dynamic stabilizers that must compensate for the damaged ligamentous restraints.

Range of Motion Progression: Shoulder flexion and abduction in the plane of the scapula are restored progressively, targeting approximately 10° of additional range per week. We strictly avoid the combined abduction-external rotation position (the instability position) for the first 6–8 weeks. Neutral internal and external rotation exercises are the primary rotational focus of Phase 2.

Rotator Cuff Activation — Priority Muscles: The subscapularis (internal rotation) is the primary anterior cuff restraint to anterior glenohumeral translation — it is the key dynamic stabilizer damaged by disuse following anterior dislocation. The infraspinatus and teres minor (external rotators) resist superior and anterior migration of the humeral head. We rigorously prioritize these muscles from the earliest appropriate point in rehabilitation.

Isometric to Isotonic Progression: We begin with submaximal isometrics in the sling position (pain-free, with the arm supported at the side), progressing to active isotonic theraband exercises in non-provocative ranges, and then gradually expanding the movement arc within which exercises are performed as confidence and strength develop. The progression is driven by symptom response — not a fixed time schedule.

A dislocated shoulder suffers profound proprioceptive impairment — the critical neurosensory function that allows the brain to sense joint position and reflexively activate stabilizing muscles before a dislocation can occur. Rebuilding this neuromuscular 'early warning system' is as clinically important as building raw strength, and it is the defining feature of expert shoulder instability physiotherapy Bangalore.

Joint Position Sense Retraining: With eyes closed, the patient is asked to reproduce specific shoulder positions — revealing the dramatic proprioceptive deficit that follows dislocation and labral disruption. We use mirror feedback, joint position matching exercises at increasing angular velocities, and perturbation training to progressively restore mechanoreceptor function within the damaged glenohumeral joint capsule.

Perturbation Training: The patient holds a set shoulder position while the therapist applies unexpected multi-directional forces to the arm. This training specifically enhances the reactive capacity of the rotator cuff — its ability to fire reflexively and protect the joint before conscious motor control can respond. This is the neuromuscular speed at which sports-related dislocations occur, and it must be trained explicitly.

Progressive Rotator Cuff Strengthening: Full range-of-motion rotator cuff exercises with progressive resistance, including cable systems, dumbbells, and functional movement patterns. The key strength benchmark: external rotation strength reaching 80% of the unaffected side is required before return to overhead sport. External rotation to internal rotation strength ratio should achieve 65–70% (external: internal) — a ratio associated with the lowest re-dislocation risk in athletes.

Graduated Introduction of the Instability Position: From approximately Week 12, with clear evidence of rotator cuff strength and proprioceptive retraining, we carefully begin to condition the shoulder in the previously avoided abduction-external rotation position — initially with low load and high motor control cuing, progressively adding resistance and dynamic challenge.

Return to contact sport following shoulder dislocation is a high-stakes clinical decision. Premature return is the primary driver of recurrent dislocation and progressive structural damage to the glenoid and humeral head. We use objective functional testing criteria — not time alone — to guide return-to-sport clearance.

Return-to-Sport Criteria: (1) Full, pain-free range of motion in all planes including end-range external rotation with a negative apprehension test, (2) External rotation strength ≥80% of the unaffected side on clinical testing, (3) Negative apprehension and relocation tests performed by the physiotherapist, (4) Pain-free and apprehension-free performance of all sport-specific movements.

Sport-Specific Graduated Return: For rugby and contact sport athletes, rehabilitation follows a 6-week graded contact reintroduction: pad work only (Week 1–2), controlled partner tackles at 50% intensity (Week 3–4), non-contact team drills (Week 5), and full contact training (Week 6), before return to competitive match play. For cricketers, a progressive throwing program with monitored volume and intensity. For swimmers, a progressive stroke volume program beginning with freestyle and backstroke before breaststroke and butterfly.

Protective Bracing at Return to Sport: A shoulder stabilizing brace limiting external rotation to a safe angle (typically 60° or below) may be recommended for the first season of return to collision sport, particularly for young athletes who have chosen conservative management. The brace reduces — but does not eliminate — the risk of re-dislocation during the critical early return period.

The decision between conservative physiotherapy and surgical stabilization (arthroscopic Bankart repair) is one of the most important clinical discussions following a first-time shoulder dislocation. It depends on: the patient's age, activity level, sport, the extent of structural damage on MRI (size of Bankart lesion, presence and size of Hill-Sachs lesion), and the patient's personal risk tolerance for recurrence.

The evidence increasingly supports early surgical stabilization for young athletes under 25 years participating in collision sports (rugby, wrestling). Their recurrence rate exceeds 80% with conservative management alone, and each recurrence causes additional structural damage. For older, less active individuals and patients with significant medical comorbidities, a 3–6 month physiotherapy trial is the appropriate first-line approach.

For patients undergoing Bankart repair surgery, our post-operative protocol is a rigorously phased, 6-phase program coordinated with the operating surgeon: sling immobilization (Weeks 0–6), passive ROM initiation (Weeks 4–8), progressive active ROM (Weeks 8–12), rotator cuff strengthening (Weeks 12–20), sport-specific training (Months 5–8), and return to full contact sport at approximately 9 months. Post-operative rehabilitation quality is the single most important determinant of long-term surgical outcome.
