Shoulder Tendinitis Exercises: Relieve Tendon Pain and Inflammation

Shoulder tendinitis is inflammation or irritation of the tendons in the shoulder, most commonly affecting the rotator cuff or biceps tendon. It often develops from repetitive overhead movements, poor posture, or sudden increases in activity. The right exercises can reduce pain, promote healing, and prevent recurrence.

Understanding Shoulder Tendinitis

Common Types

Rotator Cuff Tendinitis:

• Supraspinatus (most common)
• Infraspinatus
• Teres minor
• Subscapularis

Biceps Tendinitis:

• Long head of biceps at front of shoulder

Causes

• Repetitive overhead activities
• Poor posture (rounded shoulders)
• Muscle imbalances
• Sudden increase in activity
• Age-related degeneration
• Impingement (tendons pinched in shoulder)

Symptoms

• Pain with overhead reaching
• Night pain (lying on shoulder)
• Weakness with lifting
• Pain in front or side of shoulder
• Stiffness after rest
• Clicking or grinding sensation

Important Distinction

Tendinitis = acute inflammation (recent onset) Tendinosis = chronic degeneration (long-standing)

Treatment approach differs slightly, but exercises help both conditions.

Phase 1: Pain Relief and Mobility

Goals

• Reduce inflammation
• Maintain range of motion
• Avoid aggravating movements
• Begin gentle activation

Pendulum Exercises

Gentle motion without muscle activation:

1. Lean forward, support with uninjured arm on table
2. Let injured arm hang freely
3. Gently swing arm in small circles
4. Swing forward/backward, side to side
5. Let momentum do the work—stay relaxed

Perform: 1-2 minutes, 3-4 times daily

Passive Range of Motion

Use other arm to move shoulder:

Assisted Flexion:

1. Lie on back, hold injured arm with other hand
2. Lift arm overhead, keeping elbow straight
3. Use good arm to control movement
4. Lower slowly

Assisted External Rotation:

1. Lie on back, elbow at side bent 90 degrees
2. Use other hand or stick to rotate forearm outward
3. Keep elbow pinned to side
4. Return to neutral

Perform: 15-20 reps each direction, 2-3 times daily

Posterior Capsule Stretch

Tight posterior structures contribute to impingement:

1. Bring injured arm across body
2. Use other hand to pull elbow toward opposite shoulder
3. Feel stretch in back of shoulder
4. Hold 30 seconds

Perform: 3-4 reps, 2-3 times daily

Doorway Pec Stretch

Open the front of shoulder:

1. Stand in doorway
2. Place forearm on door frame, elbow at shoulder height
3. Step through doorway until stretch felt in chest
4. Hold 30 seconds
5. Adjust arm height to target different fibers

Perform: 3 reps at each height, 2-3 times daily

Ice and Activity Modification

• Ice shoulder 15-20 minutes after activity
• Avoid painful overhead movements temporarily
• Sleep on uninjured side or back
• Modify work/sport activities as needed

Phase 2: Activation and Early Strengthening

Goals

• Activate rotator cuff muscles
• Begin scapular stabilization
• Progress strengthening cautiously
• Maintain flexibility gains

Isometric External Rotation

No movement, build activation:

1. Stand with elbow at side, bent 90 degrees
2. Press back of hand against wall or door frame
3. Push as if rotating outward
4. Hold 5-10 seconds
5. No movement should occur

Perform: 10 reps, 5-10 second holds, 3 sets

Isometric Internal Rotation

1. Same position as above
2. Push palm into wall as if rotating inward
3. Hold 5-10 seconds

Perform: 10 reps, 5-10 second holds, 3 sets

Sidelying External Rotation

Classic rotator cuff exercise:

1. Lie on uninjured side
2. Upper arm at side, elbow bent 90 degrees
3. Rotate forearm upward toward ceiling
4. Keep elbow pinned to side
5. Lower slowly

Perform: 15-20 reps, 3 sets (no weight or light weight)

Prone Y, T, W Raises

Build scapular stability:

Y Raise:

1. Lie face down on floor or bench

Perform: 15-20 reps, 3 sets

Low Rows (Cable or Band)

Scapular strengthening:

1. Hold band or cable at arm's length
2. Pull elbows back, squeezing shoulder blades
3. Keep shoulders down (don't shrug)
4. Return slowly

Perform: 15-20 reps, 3 sets

Phase 3: Progressive Strengthening

Goals

• Build rotator cuff strength
• Progress resistance appropriately
• Improve functional capacity
• Address contributing factors

Resistance Band External Rotation

1. Anchor band at elbow height
2. Stand with elbow at side, bent 90 degrees
3. Rotate forearm outward against resistance
4. Keep elbow fixed to side
5. Return slowly

Resistance Band Internal Rotation

1. Same setup, face opposite direction
2. Rotate forearm inward against resistance
3. Keep elbow fixed
4. Control return

Perform: 15-20 reps, 3 sets

High Row to External Rotation

Combines scapular stability with rotation:

1. Band anchored at face height
2. Pull elbows back (row position)
3. From there, rotate hands upward
4. Reverse the movement

Perform: 12-15 reps, 3 sets

Standing Scaption

When to Seek Help

Red Flags

See a provider if:

• Pain persists beyond 4-6 weeks of exercise
• Weakness that doesn't improve
• Night pain that disrupts sleep
• Signs of tear (sudden weakness, bruising)
• Pain with all shoulder movements

Treatment Options

If conservative measures fail:

• Physical therapy
• Corticosteroid injection
• PRP or other regenerative options
• Surgery (usually last resort for tears)

Common Mistakes

1. Continuing painful activities - Modify until pain-free
2. Skipping posterior chain - Back of shoulder often weak
3. Poor posture - Rounded shoulders worsen impingement
4. Too much, too fast - Progress weight gradually
5. Neglecting scapular stability - Foundation for rotator cuff

Key Takeaways

Shoulder tendinitis responds well to targeted exercise:

1. Rest from aggravating activities, not all movement
2. Address posture - Often a primary contributor
3. Strengthen rotator cuff - Focus on external rotators
4. Don't forget scapular muscles - They support the cuff
5. Be patient - Full recovery often takes 8-12 weeks

Consistency with exercises is more important than intensity. Most cases of shoulder tendinitis resolve with proper conservative management.
