Supraspinatus Tendon Injuries: Symptoms, Awareness & Activity Considerations

The supraspinatus tendon connects the supraspinatus muscle to the shoulder joint and helps lift the arm away from the body. It is part of the rotator cuff, a group of muscles and tendons that stabilize the shoulder and support daily movement.

Relevance in Aging, Sports & Canadian Workplaces

Rotator cuff discomfort is a common source of shoulder pain among adults, particularly with aging, repetitive lifting, overhead work, or throwing sports. Many cases involve gradual tendon wear rather than sudden trauma. Awareness of tendon injuries helps individuals recognize when to seek assessment rather than ignoring persistent shoulder symptoms.

Scenario: Mild, Realistic & Non-Dramatic

A grocery store employee noticed shoulder discomfort when lifting boxes to overhead shelves. Over time, reaching into cupboards at home also became uncomfortable. A physiotherapist suspected supraspinatus tendon irritation and recommended exercises and temporary activity modification. Symptoms improved gradually.

How Injuries Develop

Supraspinatus tendon issues may arise from:

Repetitive overhead movements (painting, stocking, swimming, tennis, throwing)
Age-related tendon changes or degeneration
Previous shoulder injuries
Poor posture or muscle imbalance
Acute trauma (less common than degeneration)

These changes can lead to irritation, partial tears, or—more rarely—full-thickness tears.

Possible Symptoms (Awareness Only)

Common symptoms may include:

Pain when lifting the arm or reaching overhead
Shoulder weakness or fatigue during activity
Night discomfort when lying on the affected shoulder
Reduced range of motion
Swelling or tenderness around the joint

Some people notice difficulty performing tasks such as dressing, brushing hair, or lifting items to shelves.

Age-Related Considerations

Rotator cuff wear becomes more common with age due to decreased tendon hydration and elasticity. Some tears in older adults are incidental findings on imaging and do not always cause symptoms.

Assessment & Imaging (Awareness)

Healthcare professionals may assess:

Shoulder strength and motion
Pain during specific movement patterns
Posture and muscle balance
Imaging when required (e.g., ultrasound or MRI)

Assessment helps distinguish supraspinatus injuries from bursitis, arthritis, impingement, and other shoulder conditions that have overlapping symptoms.

Activity & Recovery Considerations

Management is individualized and may involve:

Temporary modification of overhead activities
Physiotherapy or exercise programs
Workplace or sport adjustments
Strengthening for shoulder + upper back
Posture and ergonomic strategies

Surgical options may be considered in certain situations, such as persistent loss of strength or function, but these decisions are guided by healthcare professionals.

Workplace & Sport Prevention Strategies

Prevention may include:

Gradual conditioning for overhead tasks
Strength and mobility training for rotator cuff and scapular stabilizers
Ergonomic adjustments for repeated lifting
Warm-up routines in overhead sports
Avoiding sudden spikes in training load

FAQ

1. Are supraspinatus injuries always caused by sports?
No. Many develop gradually due to aging or repetitive daily movements.

2. Can a supraspinatus tear heal without surgery?
Some individuals improve with rehabilitation, depending on tear type, age, and function.

3. Why does the shoulder hurt at night?
Night pain is common with rotator cuff irritation due to pressure on tissues while lying down.

4. Are degenerative tears common?
Yes. They are more common in older adults and may exist without symptoms.

5. Can strength return after injury?
Strength and function often improve with rehabilitation and guidance, depending on severity.
