Shoulder impingement syndrome (SIS) is a common condition that results when the rotator cuff tendons are irritated as they pass through the subacromial space, causing pain and reduced mobility. Often referred to as "swimmer’s shoulder" or "pitcher’s shoulder," this condition can affect athletes and non-athletes alike. Effective rehabilitation is crucial in managing pain, improving range of motion, and strengthening the shoulder to prevent further injury. This article covers the best exercises for rehabbing shoulder impingement, focusing on improving strength, flexibility, and mobility.

Understanding Shoulder Impingement
Before delving into the rehab exercises, it’s essential to understand the mechanics behind shoulder impingement.
The shoulder joint is a complex structure comprising bones, muscles, ligaments, and tendons. The rotator cuff, a group of four muscles and their associated tendons, is responsible for stabilizing the shoulder and enabling a wide range of motion. In shoulder impingement, these tendons become compressed between the bones of the shoulder, particularly the acromion (part of the shoulder blade) and the humeral head (upper arm bone). This compression leads to inflammation, pain, and restricted movement.
The primary goals of shoulder impingement rehabilitation are to:
1. Reduce inflammation and pain.
2. Restore range of motion.
3. Strengthen the muscles around the shoulder, particularly the rotator cuff and scapular stabilizers.
4. Improve posture and shoulder mechanics to prevent future impingement.

Key Exercises for Shoulder Impingement Rehab
Rehabilitative exercises for shoulder impingement focus on improving shoulder mobility, flexibility, and strength. Below are some of the most effective exercises that can help in recovery.
1. Pendulum Swings (Codman’s Exercise)
Purpose: Improves joint mobility and relieves tension.
How to Perform:
1. Stand with your unaffected arm supported on a table or chair for balance.
2. Let the affected arm hang loosely towards the ground.
3. Slowly swing the arm in small circular motions, first clockwise and then counterclockwise.
4. Progress to larger circles as tolerated. Perform for 1-2 minutes.
Benefits: This exercise uses gravity to help mobilize the shoulder without straining the rotator cuff, promoting movement and circulation to the joint.
---
2. Passive Shoulder Flexion with a Dowel (Shoulder Wand Exercise)
Purpose: Increases shoulder range of motion.
How to Perform:
1. Lie on your back with a dowel or broomstick in both hands.
2. Keeping your arms straight, gently lift the stick towards your head using the unaffected arm to assist the injured arm.
3. Go as far as you can without pain and hold for 5-10 seconds.
4. Repeat for 10-15 repetitions.
Benefits: This exercise allows controlled movement, helping to improve shoulder flexion with minimal discomfort.

3. Wall Angels
Purpose: Enhances shoulder mobility and improves posture by activating scapular muscles.
How to Perform:
1. Stand with your back against a wall, with your feet about six inches away.
2. Keep your lower back, shoulders, and head in contact with the wall.
3. Start with your arms bent at 90 degrees, palms facing forward, and elbows against the wall.
4. Slowly raise your arms up the wall, maintaining contact with the wall, then lower them back down.
5. Perform 10 repetitions.
Benefits: Wall angels improve scapular control and shoulder blade positioning, which helps alleviate pressure on the rotator cuff.

4. Scapular Retraction with Resistance Band
Purpose: Strengthens the scapular stabilizers (rhomboids, trapezius) and improves shoulder blade mechanics.
How to Perform:
1. Attach a resistance band to a secure point at chest height.
2. Hold the band with both hands, keeping your arms straight in front of you.
3. Pull the band towards you, squeezing your shoulder blades together as you retract your shoulders.
4. Slowly return to the starting position.
5. Perform 2-3 sets of 12-15 repetitions.
Benefits: Strengthening the scapular muscles ensures better shoulder blade stability, preventing further impingement.
---
5. External Rotation with Resistance Band
Purpose: Strengthens the external rotators of the shoulder, especially the infraspinatus and teres minor muscles of the rotator cuff.
How to Perform:
1. Attach a resistance band to a door handle or any secure object.
2. Hold the band with the hand of the affected arm, keeping your elbow bent at 90 degrees and close to your body.
3. Slowly rotate your arm outward, keeping your elbow tucked in.
4. Control the movement as you return to the starting position.
5. Perform 2-3 sets of 10-15 repetitions.
Benefits: External rotation exercises help restore strength to the rotator cuff muscles, reducing the risk of future injury.
---
6. Sleeper Stretch
Purpose: Increases flexibility in the posterior shoulder, reducing impingement symptoms.
How to Perform:
1. Lie on your affected side with your arm at a 90-degree angle to your body.
2. Use your unaffected hand to gently press the affected arm down towards the floor, keeping your shoulder and elbow in place.
3. Hold the stretch for 20-30 seconds, then release.
4. Perform 3-5 repetitions.
Benefits: This stretch targets the posterior capsule of the shoulder, often tight in cases of shoulder impingement.
---
7. Prone Shoulder Extension
Purpose: Strengthens the posterior deltoid and other shoulder extensor muscles.
How to Perform:
1. Lie face down on a table or bed with your affected arm hanging over the edge.
2. Keeping your arm straight, slowly lift it behind you (into extension), squeezing your shoulder blade at the top of the motion.
3. Lower the arm back to the starting position.
4. Perform 2-3 sets of 10-12 repetitions.
Benefits: Prone shoulder extensions help build strength in the posterior muscles of the shoulder, promoting better joint stability.

Additional Tips for Shoulder Impingement Rehab
1. Focus on Posture
Poor posture, particularly rounded shoulders and a forward head posture, is a significant contributor to shoulder impingement. Incorporating exercises that promote good posture, such as rows and scapular retraction, can be beneficial. Practicing good posture throughout the day, especially while sitting or working at a desk, will help reduce shoulder strain.
2. Pain Management
During the early stages of rehab, it’s crucial to manage inflammation and pain. Ice therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), and physical therapy modalities (such as ultrasound or TENS) may be recommended by a healthcare provider to reduce pain.
3. Gradual Progression
It’s essential to progress slowly with rehab exercises. Start with lighter resistance and fewer repetitions, gradually increasing as your shoulder strengthens. Avoid pushing through sharp pain, as this may worsen the injury.
4. Consult a Professional
Although these exercises can be beneficial, it’s essential to consult a healthcare professional or physical therapist to create a customized rehab plan that fits your specific needs.

Conclusion
Rehabbing shoulder impingement requires a combination of mobility, flexibility, and strengthening exercises to address the underlying causes of the condition. By following a well-rounded rehabilitation program and focusing on proper technique, posture, and progression, you can reduce pain, improve range of motion, and prevent future shoulder impingement. Always listen to your body, avoid pushing through pain, and consult a professional to ensure a safe and effective recovery.
