After shoulder immobilization for a month, what you are experiencing is called shoulder stiffness / post-immobilization adhesive changes - the muscles, tendons, and joint capsule tighten up from disuse. This is very common and manageable.

Here is a thorough, practical guide based on orthopedic textbooks and clinical evidence:
Shoulder Stiffness After 1 Month of Immobilization
What you are feeling - struggling and tightness when trying to flex (lift) your shoulder - is completely expected. After a month in a sling or cast, the joint capsule shrinks, muscles weaken, and scar tissue forms around the shoulder. This is called post-immobilization stiffness, and if not addressed, it can progress to frozen shoulder (adhesive capsulitis).
Why It Happens
The shoulder is the most sensitive joint in the body to immobilization (Rockwood and Green's Fractures in Adults, 10th ed.). Even a few weeks of restricted movement leads to:
- Tightening of the joint capsule
- Muscle atrophy (especially the rotator cuff and deltoid)
- Loss of glenohumeral (ball-and-socket) motion
- Loss of scapular movement (the "struggling" or shrugging motion you feel is your shoulder blade compensating for limited ball-socket movement)
What That "Struggling" Motion Means
When your shoulder joint is tight, your body cheats - it uses the shoulder blade (scapula) to hike up and help with lifting. This is called abnormal scapular substitution or "shoulder hiking." You want to retrain the true shoulder joint to do the work.
How to Prevent Worsening and Regain Movement
Start with a physiotherapist if you can - this is strongly recommended by Schwartz's Principles of Surgery and Rockwood & Green's. But here are the core exercises used in clinical rehabilitation:
Phase 1 - Passive/Gentle Motion (Weeks 1-2 of rehab)
1. Pendulum (Codman) Exercises
- Lean forward, let the arm hang freely
- Gently swing the arm in small circles - forward/back and side to side
- Use gravity, NOT muscle force - let the arm be like a pendulum
- Do 2-3 minutes, 3-4 times a day
- This loosens the capsule without stressing healing tissues
2. Supine (lying down) Passive Forward Flexion
- Lie on your back
- Use your good arm (or a stick/wand) to gently lift the stiff arm upward overhead
- Hold at the end of comfortable range for 10-15 seconds
- Repeat 10 times, 2-3 times daily
3. Pulley / Wall Crawl
- Face a wall, use your fingers to "crawl" up the wall slowly
- Go to the point of stretch (not pain), hold 5 seconds, slide down
- Repeat 10 times daily
- Mark your progress on the wall each day
Phase 2 - Active-Assisted Motion (Weeks 2-4)
4. Wand/Stick-Assisted Elevation
- Hold a cane or broomstick with both hands
- Use the good arm to push the stiff arm forward and up
- This gives you "assisted active" movement - muscles start working with help
5. External Rotation Stretch
- Hold the stick horizontally at waist height
- Use good arm to gently rotate the stiff arm outward
- Hold 15-20 seconds, 3 sets
6. Cross-Body Stretch (for posterior capsule)
- Bring the stiff arm across your chest with the other arm
- Hold gently for 20-30 seconds
- Do 3-4 times a day
Phase 3 - Strengthening (After range is improving)
7. Isometric Exercises
- Press your hand gently against a wall in different directions (forward, sideways, backward) without moving the arm
- Hold 5 seconds, 10 reps - this rebuilds muscle without stressing the joint
8. Resistance Band Rotator Cuff Exercises
- External and internal rotation with a resistance band at elbow level
- This rebuilds the small muscles that control and center the shoulder joint
Key Rules to Follow
| Do This | Avoid This |
|---|---|
| Warm up with heat (10 min) before exercises | Forcing through sharp pain |
| Exercise gently every day (consistency beats intensity) | Letting the arm rest completely all day |
| Stretch to the point of "pull/stretch", not pain | Aggressive yanking or gym lifting too early |
| See a physiotherapist for hands-on mobilisation | Ignoring the stiffness - it worsens over weeks |
| Use ice after exercises if swollen/painful (10-15 min) | Immobilizing again for long periods |
When to See a Doctor Urgently
- Pain is severe and worsening (not just stretch discomfort)
- Numbness or tingling down the arm
- You still cannot raise the arm above shoulder height after 4-6 weeks of rehab
- Signs of infection if you had surgery (swelling, redness, fever)
Summary
Your shoulder is stiff and weak from one month of immobilization - this is normal and fully treatable with physiotherapy. Start with pendulum exercises and passive stretching, progress to active-assisted exercises, and then strengthening. The "struggling" you feel is your shoulder blade compensating for a stiff joint capsule - consistent daily gentle stretching will fix this over 4-8 weeks.
The most important advice from orthopaedic surgery textbooks (Schwartz's Principles of Surgery, 11th ed.): "Physiotherapy should be started within 2 weeks of injury to prevent stiffness" - so you want to begin rehabilitation immediately and consistently.
Here is a good video demonstrating the core exercises:
Note: This is general guidance. Since you have been immobilized for a specific reason (fracture, dislocation, surgery etc.), always confirm with your treating doctor or physiotherapist before starting exercises to make sure your healing is at the right stage.
What exercises would you recommend for external rotation ( it is more stiff than any other muscle)
External rotation stiffness after immobilization is the most common finding - the shoulder is typically immobilized in internal rotation (arm across the body in a sling), so the external rotators and the posterior/anterior capsule tighten the most.

Here is a focused, progressive plan specifically for tight external rotation after shoulder immobilization:
Exercises for Shoulder External Rotation Stiffness
Why External Rotation Gets So Stiff
When your arm is in a sling, it sits in internal rotation (elbow bent, hand across your belly). This position chronically shortens the anterior capsule and the subscapularis muscle, while the external rotators (infraspinatus and teres minor) become weak and the posterior capsule tightens. Together, these changes block external rotation the most.
Phase 1 - Passive Stretching (Start Here, Week 1)
The goal is to gently lengthen the tight anterior capsule and subscapularis. Go to the point of a firm stretch, not pain. Hold each stretch 20-30 seconds.
1. Supine External Rotation Stretch (Most Important)
Best first exercise for post-immobilization ER stiffness
- Lie on your back
- Bend the elbow to 90 degrees, upper arm resting at your side
- Let gravity gently rotate the forearm outward toward the floor
- If it doesn't go far, use your other hand to gently assist - push the wrist down toward the floor
- Hold 20-30 seconds, 3-5 reps
- Do this 2-3 times daily
This is the safest starting position because gravity does the work and you have full control.
2. Wand/Stick External Rotation Stretch
(Active-assisted - use the good arm to help)
- Sit or stand, elbow bent at 90 degrees at your side
- Hold a stick/cane horizontally with both hands
- Use the good arm to gently push the affected wrist outward (rotating the stiff shoulder out)
- Hold 15-20 seconds at end range, release, repeat 10 times
- Do 2-3 sets, twice daily
This is one of the standard physiotherapy exercises shown in frozen shoulder research for restoring external rotation.
3. Doorway / Sleeper Anterior Capsule Stretch
(Stretches the tight anterior capsule that blocks ER)
- Stand in a doorway, elbow bent at 90 degrees
- Place forearm on the door frame (like taking an oath)
- Gently lean your body forward through the doorway - you'll feel a stretch in the front of the shoulder
- Hold 20-30 seconds, 3 reps
- Do 2-3 times daily
This directly targets the anterior capsule and pectoral tightness that physically blocks the arm from rotating outward.
4. Posterior Capsule Stretch (Cross-Body)
(Releases the posterior capsule, which also limits ER)
- Bring the stiff arm across your chest horizontally
- Use the other hand to gently pull the elbow toward your opposite shoulder
- Hold 20-30 seconds, 3-4 reps
- Do daily
Phase 2 - Active Mobility (Week 2-3)
Once you can feel your range starting to come back, add these:
5. Active External Rotation in Supine
- Same lying-down position as #1
- Now try to rotate the forearm outward under your own muscle power (without using the other hand)
- Only go as far as you can actively control - you may only get a few degrees at first
- Hold 2-3 seconds at end range, return slowly
- 10-15 reps, 2 sets
This trains the infraspinatus and teres minor to start working again.
6. Side-Lying External Rotation (Gravity-Resisted)
- Lie on the unaffected side
- Stiff arm on top, elbow bent at 90 degrees, resting against your body
- Slowly rotate the forearm upward toward the ceiling
- Hold 2 seconds at top, lower slowly
- 10-15 reps, 2-3 sets
This is the best exercise for isolating the infraspinatus. Research (EMG studies) shows this position gives the highest activation of the external rotators with the least compensation.
Phase 3 - Strengthening (Week 4+ when range is improving)
7. Resistance Band External Rotation (Elbow at Side)
- Attach a light resistance band to a door or fixed point
- Stand sideways, elbow bent 90 degrees, tucked at your side
- Small towel roll between elbow and ribs (keeps the upper arm still)
- Rotate forearm outward against the band resistance
- Slow and controlled - 3 seconds out, 2 seconds back
- 15 reps, 3 sets
8. Band External Rotation at 45 Degrees Abduction
- Same as above, but lift the arm out to the side at 45 degrees before rotating
- This is a more functional position used in daily tasks and is considered the best position for rotator cuff strengthening
Daily Routine Summary
| Time | Exercise | Sets x Reps |
|---|---|---|
| Morning (after warm shower) | Supine ER stretch | 3 x 20 sec hold |
| Morning | Wand ER stretch | 3 x 10 reps |
| Morning | Doorway stretch | 3 x 20 sec hold |
| Evening | Side-lying ER (active) | 2 x 15 reps |
| Evening | Cross-body posterior stretch | 3 x 20 sec hold |
- Warm the shoulder first - a warm shower or heat pack (10 min) before stretching makes the capsule more pliable
- Ice after if sore - 10-15 minutes
- Progress to resistance band only when passive range is nearly restored
- Expect 4-8 weeks for meaningful ER improvement with daily consistency
Key Tip
Do the stretches slowly and daily - short frequent sessions beat long infrequent ones. Sudden sharp pain means stop. A "pulling/stretching" sensation is expected and good.
Here is a video demonstrating correct form for external rotation strengthening:
If your external rotation is still very limited (less than 20-30 degrees) after 3-4 weeks of consistent stretching, see a physiotherapist - manual capsular mobilization done by a therapist can unlock the joint faster than exercises alone.
My physiotherapist said that internal rotation has come to 90 percent Flextion and abduction came to 90 percent but the external rotation doesnt reach 50 percent what should do
This is a very specific and important finding. Having internal rotation at 90%, flexion and abduction at 90%, but external rotation stuck below 50% points to a specific problem - a tight anterior capsule and/or a tight subscapularis muscle that is selectively restricting external rotation.

shoulder external rotation deficit anterior capsule mobilization
This is a very clear clinical picture. Your situation is well understood in physiotherapy - when everything else recovers but external rotation lags, it means the anterior capsule and subscapularis are specifically tight. Here is exactly what you and your physiotherapist should focus on:
Why Only Your External Rotation is Stuck
Your pattern (IR 90%, flexion 90%, abduction 90%, ER <50%) tells a specific story:
- The anterior joint capsule has thickened and tightened from the immobilization position (arm across body in sling = internal rotation)
- The subscapularis (a powerful internal rotator muscle) is shortened and inhibited
- The other directions have recovered because they are less affected by the sling position
This pattern is very similar to early adhesive capsulitis (frozen shoulder), where external rotation is consistently the most restricted movement and the last to recover.
What the Research Says Works Best
A key RCT published in JOSPT found that patients who received posterior glide joint mobilization improved their external rotation by 31 degrees in just 3 sessions, versus only 3 degrees in the group who received anterior glide. This means the direction of mobilization matters enormously.
A second study found that 4 specific self-stretches done at least twice daily produced satisfactory outcomes in 90% of patients with stubborn ER restriction (Griggs et al.).
The Targeted Plan for Your Situation
A. Tell Your Physiotherapist to Do This (Manual Therapy)
Ask specifically for posterior glide mobilization (Grade III-IV) of the glenohumeral joint. This is a hands-on technique where the therapist pushes the head of the humerus backward in the socket while the arm is positioned at end-range of external rotation. Research shows this is significantly more effective for ER recovery than anterior glide.
This is NOT something you can do yourself - the therapist needs to do it. It can unlock meaningful ER range in just 3-5 sessions.
B. Self-Exercises at Home (Do These Daily, Twice a Day)
These are the 4 stretches shown to produce 90% success in stubborn capsular ER restriction:
1. Cane External Rotation Stretch (Most Important - Do This First)
Target: Anterior capsule directly
- Sit or stand, elbow bent to 90 degrees, tucked at your side
- Hold a cane/stick horizontally with both hands
- Use the good arm to slowly push the stiff wrist outward
- Go to the point where you feel a firm pull at the front of the shoulder
- Hold 30-60 seconds (longer holds work better for capsule - not 10-second holds)
- Repeat 3-5 times per session
- Do this twice daily - morning after warm shower, and evening
The key upgrade here: hold longer. Short 10-second stretches change muscle. Long 30-60 second holds change the joint capsule itself.
2. Supine ER Stretch with Arm at Side (Gravity-Assisted)
Target: Anterior capsule at 0 degrees abduction
- Lie on your back, upper arm resting flat against your side
- Elbow bent to 90 degrees
- Let the forearm drop outward toward the floor using gravity
- Use the other hand to gently push the wrist further down if tolerated
- Hold 60 seconds, 3 reps
- The floor/gravity acts as a constant gentle load on the capsule
3. Supine ER Stretch with Arm at 90 Degrees Abduction (Advanced)
Target: Anterior-inferior capsule at 90 degrees - this is the position where ER loss is most functionally important
- Lie on your back
- Raise the stiff arm to 90 degrees abduction (arm out to the side like a T)
- Elbow bent to 90 degrees, forearm pointing toward the ceiling
- Slowly let the forearm fall backward toward the floor (rotating outward)
- Use the other hand to gently assist if needed
- Hold 30-60 seconds, 3 reps
- This stretches the anterior-inferior capsule which is the thickest restricted area
4. Doorway / Sleeper Anterior Capsule Stretch
Target: Pectoralis minor and anterior capsule together
- Stand facing a doorway, forearm resting on the frame at shoulder height
- Gently rotate and lean your whole body away from the arm
- You will feel a deep stretch at the front of the shoulder
- Hold 30-45 seconds, 3 reps
- Do 2-3 times daily
5. Posterior Capsule Stretch (Cross-Body)
This seems counterintuitive but is important - a tight posterior capsule actually shifts the humeral head forward and blocks external rotation from the other side
- Bring the stiff arm horizontally across your chest
- Use the good arm to gently pull the elbow inward and downward
- Hold 30-45 seconds, 3-4 reps daily
C. Add Heat Before, Ice After
| Timing | What to Do |
|---|---|
| 10 minutes before stretching | Warm shower OR heat pack on shoulder |
| During stretching | Slow, sustained holds - never bouncing |
| 10-15 minutes after | Ice pack if sore or inflamed |
Heat makes the capsule tissue more elastic and stretchable. Cold after reduces any inflammatory response.
Realistic Timeline
| Week | Expected Progress |
|---|---|
| Week 1-2 | 5-10 degrees gain if doing sustained stretches + physio mobilization |
| Week 3-4 | Another 10-15 degrees |
| Week 6-8 | Most people reach 60-70% with consistent daily work |
| Week 8-12 | Full or near-full ER recovery in most cases |
The PMC adhesive capsulitis evidence review shows 90% success with non-operative treatment (physiotherapy + stretching) over 4 months on average.
Red Flags - See Your Doctor If:
- No improvement at all after 4-6 weeks of consistent targeted stretching
- Pain is getting significantly worse (not just stretch discomfort)
- Arm feels completely locked with zero passive ER even with assistance
- Numbness, tingling, or weakness developing in the hand/fingers
In those cases, your doctor may consider a corticosteroid injection into the joint (very effective for capsular stiffness) or in rare cases, manipulation under anesthesia to forcibly break up the capsular adhesions.
Bottom line: Your recovery is going well - 3 out of 4 directions are nearly normal. The ER being stuck is a known, specific, fixable problem. The key changes from what you may already be doing: hold each stretch longer (30-60 seconds), ask your physio for posterior glide mobilization, and add the 90-degree abduction ER stretch. Expect meaningful improvement within 3-4 weeks of targeted work.
