ROTATOR CUFF INJURY (SPORTS PHYSIOTHERAPY PERSPECTIVE)
INTRODUCTION
Rotator cuff injuries are among the most common shoulder problems in athletes, particularly those
engaged in overhead sports such as swimming, tennis, baseball, volleyball, and weightlifting. The
rotator cuff is a group of four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) that
stabilize the shoulder joint and facilitate smooth arm movements. Injury to these muscles or their
tendons can result in pain, weakness, decreased range of motion, and impaired athletic performance.
Physiotherapists are crucial in the assessment, rehabilitation, and prevention of rotator cuff injuries.
Additional points: - Can be acute (traumatic) or chronic (overuse) - Leads to functional limitation in
sports and daily activities - Requires early diagnosis and structured physiotherapy for optimal recovery -
Understanding biomechanics and scapulohumeral rhythm is essential for treatment
DEFINITION
A rotator cuff injury refers to damage to one or more of the rotator cuff muscles or tendons, resulting in
pain, weakness, or impaired shoulder function. Injuries can range from mild tendinitis or partial tears to
complete tendon ruptures.
Key points: - Involves supraspinatus, infraspinatus, teres minor, subscapularis - Can be acute, chronic,
or degenerative - Leads to pain, weakness, and limited overhead activities
TYPES OF ROTATOR CUFF INJURY
1. Tendinitis / Tendinopathy
2. Inflammation of the tendon due to overuse
3. Paragraph: Tendinitis occurs from repetitive overhead movements leading to microtrauma.
Symptoms include pain during overhead activity, mild weakness, and localized tenderness.
4. Partial Tear
5. Incomplete disruption of tendon fibers
6. Paragraph: May result from repetitive stress or a sudden injury. Symptoms include pain,
weakness, and reduced range of motion, especially during lifting or throwing.
7. Complete Tear / Full-Thickness Tear
8. Complete disruption of tendon fibers
9. Paragraph: Often caused by trauma or chronic degeneration. Athletes may experience severe
pain, significant weakness, and functional limitations in overhead movements.

, 10. Impingement Syndrome
11. Compression of rotator cuff tendons under the acromion
12. Paragraph: Common in overhead athletes, causing pain during arm elevation and potential
progression to tendon tears if untreated.

├─ Tendinitis / Tendinopathy
├─ Partial Tear
├─ Complete / Full-Thickness Tear
└─ Impingement Syndrome
ETIOLOGY
• Repetitive overhead activities in sports
• Acute trauma: falls, collisions, or lifting heavy loads
• Degenerative changes with aging
• Poor biomechanics or muscle imbalance
Bullet points: - Microtrauma from repeated use - Acute tendon rupture due to sudden force -
Anatomical factors: subacromial space narrowing - Muscle imbalance: weak rotator cuff or scapular
stabilizers
RISK FACTORS
• Overhead sports participation
• Age (degenerative changes in athletes >40 years)
• Previous shoulder injury
• Poor scapular control or postural abnormalities
• Muscle weakness or fatigue
CLINICAL FEATURES
Symptoms: - Pain during overhead activities, lifting, or throwing - Night pain affecting sleep -
Weakness, particularly in abduction and external rotation - Reduced range of motion
Signs: - Positive impingement tests (Neer, Hawkins-Kennedy) - Drop arm test positive - Muscle atrophy
of supraspinatus or infraspinatus - Painful arc between 60–120 degrees of abduction
Bullet points: - Pain localized to lateral shoulder - Loss of functional capacity for sports - Weakness or
inability to lift arm overhead - Tenderness on palpation of rotator cuff tendons
