The supraspinatus muscle is one of the four muscles that form the rotator cuff of the shoulder. Its tendon passes beneath the acromion (a bony projection of the shoulder blade) and attaches to the top of the humerus (upper arm bone).

The supraspinatus plays a crucial role in:

• Initiating shoulder abduction (lifting the arm away from the body)
• Stabilizing the shoulder joint
• Maintaining proper shoulder mechanics during movement

Supraspinatus Tendinitis occurs when the tendon becomes inflamed, irritated, or degenerates due to overuse, repetitive stress, or age-related wear and tear. In many cases, the condition progresses from acute inflammation (tendinitis) to chronic tendon degeneration (tendinopathy).

The tendon is particularly vulnerable because it passes through the subacromial space, where it may become compressed during arm movements, leading to shoulder impingement syndrome.

If left untreated, supraspinatus tendinitis can progress to:

• Partial tendon tears
• Full-thickness rotator cuff tears
• Chronic shoulder pain
• Reduced shoulder function

At Magnum Physiotherapy, our evidence-based rehabilitation programs focus on reducing pain, correcting biomechanics, restoring strength, and preventing recurrence.

Anatomy Involved

Rotator Cuff Muscles

• Supraspinatus – initiates arm elevation
• Infraspinatus – external rotation
• Teres Minor – external rotation and stability
• Subscapularis – internal rotation

Other Structures Commonly Involved

• Subacromial Bursa
• Acromion
• Glenohumeral Joint
• Biceps Tendon
• Scapular Stabilizing Muscles

Common Symptoms

• Pain on the outer or upper shoulder
• Pain when lifting the arm
• Difficulty reaching overhead
• Pain during dressing or grooming
• Night pain, especially when lying on the affected side
• Shoulder weakness
• Pain while throwing or lifting objects
• Clicking or catching sensation
• Reduced range of motion
• Stiffness after periods of rest

Causes & Risk Factors

Overuse Causes

• Repetitive overhead activities
• Throwing sports
• Swimming
• Tennis
• Weightlifting

Occupational Causes

• Painting
• Carpentry
• Construction work
• Repetitive lifting

Biomechanical Factors

• Poor posture
• Scapular dyskinesis
• Shoulder instability
• Muscle imbalance

Degenerative Causes

• Age-related tendon changes
• Reduced blood supply to the tendon

Risk Factors

• Age above 40 years
• Previous shoulder injuries
• Repetitive overhead work
• Poor shoulder mechanics

Types of Supraspinatus Tendon Injury

Acute Tendinitis

Sudden inflammation caused by overuse or injury.

Chronic Tendinopathy

Long-term degeneration of the tendon.

Partial Thickness Tear

Only part of the tendon fibers are torn.

Full Thickness Tear

Complete rupture of the tendon.

Conditions Associated with Supraspinatus Tendinitis

• Shoulder Impingement Syndrome
• Rotator Cuff Tear
• Subacromial Bursitis
• Adhesive Capsulitis (Frozen Shoulder)
• Biceps Tendinopathy
• Acromioclavicular Joint Dysfunction
• Glenohumeral Instability

Diagnosis

At Magnum Physiotherapy, we conduct a comprehensive shoulder assessment to identify tendon involvement and contributing factors.

The evaluation may include:

• Detailed medical history
• Pain assessment
• Range of motion testing
• Muscle strength assessment
• Scapular movement analysis
• Postural assessment
• Functional evaluation

Special Clinical Tests

• Empty Can (Jobe) Test
• Hawkins-Kennedy Test
• Neer Impingement Test
• Painful Arc Test
• Drop Arm Test

Imaging Studies

• Ultrasound
• MRI scans
• X-rays (to identify bone spurs or arthritis)

Benefits of Physiotherapy for Supraspinatus Tendinitis

• Reduces pain and inflammation
• Restores shoulder mobility
• Strengthens the rotator cuff
• Improves shoulder stability
• Corrects movement patterns
• Enhances posture
• Prevents recurrence
• Supports return to sports and work
• Reduces risk of tendon tears
• Improves quality of life

When Is Surgery Needed?

Surgery may be considered when:

• Conservative treatment fails
• Large or complete tendon tears occur
• Significant weakness persists
• Functional limitations are severe

Post-surgical physiotherapy is essential for optimal recovery.

Recovery & Prognosis

Recovery depends on:

• Severity of tendon injury
• Duration of symptoms
• Patient age and activity level
• Compliance with rehabilitation

Mild cases may recover within 6–12 weeks, while chronic cases or tendon tears may require several months of rehabilitation.

Prevention Tips

• Warm up before exercise
• Strengthen rotator cuff muscles
• Improve posture
• Avoid repetitive overhead strain
• Use proper lifting techniques
• Address shoulder pain early
• Maintain shoulder flexibility
