Overview
A shoulder dislocation happens when the top of your upper arm bone (the humerus) fully pops out of the shoulder socket joint (the glenohumeral joint), most often forward and out the front. After the joint is put back in place (called a reduction), rehab focuses on protecting the healing capsule while rebuilding strength and control.
The main long-term risk after a first dislocation, especially in younger, active people, is repeat instability. A structured rehab program built around stability and rotator cuff strength meaningfully reduces that risk (Sanford Health Anterior Glenohumeral Dislocation Rehabilitation Guideline).
This is general education. Some movement directions need to be avoided early on to protect healing tissue, so follow your physiotherapist's specific precautions over general guidance here.
Who This Guide Is For
- People recovering from a shoulder dislocation (most commonly anterior, meaning the arm bone moved forward out of the socket)
- People in a sling or early motion-restriction period following a reduction, whether treated conservatively or surgically
Pair this guide with the shoulder dislocation injury page for more on causes, symptoms, and diagnosis.
Goals of Rehabilitation
- Protect the healing joint capsule from re-injury during the early weeks
- Reduce pain, swelling, and protective muscle guarding
- Rebuild rotator cuff strength and balance between internal and external rotation
- Restore full, controlled range of motion
- Improve the shoulder's sense of position and stability (proprioception)
- Return safely to sport, lifting, or overhead work with a low risk of repeat dislocation
Phase 1: Early Stage
Typical timing: Weeks 0–3, depending on how long you were immobilized in a sling.
Goals:
- Reduce pain, swelling, and muscle guarding
- Protect the front of the joint capsule from re-stretching
- Prevent stiffness and muscle loss during immobilization
- Begin gentle rotator cuff activation
Exercises and stretches:
- Pendulum exercise — gentle passive motion within a pain-free range, avoiding the "dangerous" position of the arm out to the side and rotated outward
- Isometric shoulder holds — low-level rotator cuff activation without joint movement
- Serratus anterior punch — light version, to begin shoulder blade stabilizer activation
- Scapular retraction row — gentle version, keeping elbows in front of the body
Important precaution: In this phase, avoid forcing the arm into the combined position of lifting out to the side with outward rotation (the position that most resembles the original injury). Your physiotherapist will guide safe ranges.
Criteria to move to Phase 2:
- Pain and swelling are minimal
- The shoulder feels stable at rest and during light daily tasks
- Your physiotherapist confirms sufficient early muscle control
Phase 2: Middle Stage
Typical timing: Weeks 3–6.
Goals:
- Work toward full, pain-free range of motion
- Build rotator cuff strength, with attention to the balance between internal and external rotation strength
- Improve dynamic stability — how well the shoulder muscles control the joint during movement
- Avoid overhead lifting of weights during this phase
Exercises and stretches:
- External rotation with band — progressed gradually from close to the body toward more elevated positions
- Internal rotation with band — builds strength and helps restore rotational balance
- Wall slides — controlled overhead motion practice, kept below shoulder height early in this phase
- Sleeper stretch — performed gently, without forcing (avoid "cranking" into the stretch)
- Cross-body stretch — gentle mobility for the back of the shoulder
Criteria to move to Phase 3:
- Full, pain-free range of motion, matching or close to the other side
- No apprehension (a feeling that the shoulder might slip out) during testing or daily movement
- Rotational strength is improving and becoming more balanced
Phase 3: Late Stage / Return to Activity
Typical timing: Weeks 6–12+, with return to contact sport or heavy overhead work often not recommended before about 10–12 weeks.
Goals:
- Eliminate pain during activity
- Build strength, power, and endurance for sport- or job-specific demands
- Retrain the shoulder's stability reflexes under more challenging, less predictable conditions
- Confirm readiness for return to full activity
Exercises and stretches:
- Prone Y-T raise — builds trapezius and rotator cuff endurance
- External rotation with band — progressed to more elevated, sport-specific positions
- Overhead triceps and shoulder stretch — supports full overhead flexibility as strength builds
- Posterior capsule stretch — addresses any residual tightness at the back of the joint
Criteria to consider yourself "returned":
- No pain at rest or with activity
- No apprehension with loading or overhead positions
- Symmetrical range of motion between both shoulders
- External rotation strength at roughly two-thirds of internal rotation strength, and at least 90% of the uninjured side
Signs You're Progressing Well
- Pain and swelling are steadily decreasing
- The shoulder feels increasingly stable and "trustworthy" during daily tasks
- Strength testing shows steady improvement over successive weeks
- You have no sense that the shoulder might slip during normal movement
Signs You Should Slow Down or See a Professional
- A feeling that the shoulder is about to "pop out" or give way (apprehension)
- Sharp pain with specific positions, especially arm raised and rotated outward
- Numbness, tingling, or new weakness down the arm
- Visible deformity or a sense the shoulder has slipped partially out of place (subluxation)
- Repeated dislocation — this needs prompt medical assessment
