Rotator cuff tendonitis is when one or more of the tendons in the rotator cuff become inflamed or irritated, usually from overuse, poor shoulder mechanics, or repetitive strain. It’s a common condition, especially in people who do a lot of overhead activities, and can cause pain, stiffness, and weakness in the shoulder.

An analogy…

Think of your rotator cuff tendon like a rope sliding through a narrow tunnel (the space under your shoulder bone). If that rope is used too much or not lined up properly, it starts to fray and swell, making movement painful and restricted.

What are other names that rotator cuff tendonitis can be referred to?

Rotator Cuff Tendinitis, Rotator Cuff Tendinopathy, Supraspinatus Tendonitis, Supraspinatus Tendinitis, Supraspinatus Tendinopathy

What causes rotator cuff tendonitis?

The rotator cuff tendons pass through a small space between the acromion (part of your shoulder blade) and the humerus (upper arm bone). Repetitive overhead movement, poor posture, or muscle imbalance can cause these tendons, especially the supraspinatus tendon, to rub or get pinched, leading to inflammation. This is known as shoulder impingement, which often contributes to tendonitis.

What are the signs and symptoms of rotator cuff tendonitis?

• Pain in the front or side of the shoulder, especially with lifting or reaching overhead
• Pain that may radiate down the arm
• Discomfort when lying on the affected shoulder
• Weakness or stiffness, particularly with shoulder elevation or rotation
• Pain during specific movements, but usually no major loss of strength (unlike a tear)
• Clicking or catching sensations with movement

What tests are used to diagnose rotator cuff tendonitis?

Neer’s Test: The practitioner lifts the patient’s arm straight up in front of them while stabilising the shoulder blade. If this movement causes pain in the front or top of the shoulder, the test is considered positive.

Hawkins-Kennedy Test: The patient’s arm is raised to shoulder height and bent at the elbow. The practitioner then gently rotates the arm inward. If this causes sharp pain in the front or side of the shoulder, the test is positive.

How long does rotator cuff tendonitis take to heal?

Recovery usually takes around 4 to 8 weeks with the right treatment. If symptoms are more chronic or severe, it may take up to 3 months to fully resolve. With early intervention and proper rehab, most people recover without surgery.

How does rotator cuff tendonitis happen?

• Repetitive overhead activity
• Poor posture, especially rounded shoulders and forward head position
• Muscle imbalances
• Previous shoulder injury
• Poor lifting technique or overtraining

What treatment can help rotator cuff tendonitis?

• Manual therapy to improve joint alignment and muscle tension
• Postural correction and ergonomic advice
• A targeted rehab program focused on rotator cuff and scapular strength
• Dry needling or taping may be used to support the area

What exercises or stretches can I do for rotator cuff tendonitis?

• Isometric holds
