Rotator cuff tendinitis, and even small rotator cuff tears,can make everyday tasks like reaching, lifting the arm, typing or using the mouse feel uncomfortable. At work, symptoms often fluctuate depending on posture, arm position and how the shoulder is used throughout the day.
Because the rotator cuff plays a key role in stabilising the shoulder, irritated or weakened tissues can become more sensitive to sustained positions or overloaded movements. Understanding how workplace habits influence symptoms can help prevent flare-ups and support steady, manageable recovery.
Several common desk-based habits can increase strain on the shoulder, especially when the tendon is inflamed or partially torn.
• Working with the arm held away from the body
Reaching forward for the mouse or keyboard increases load on the rotator cuff and can aggravate symptoms.
• Desk setups that encourage shoulder elevation
A high desk or non-adjustable chair often causes the shoulders to “hike up,” creating extra tension in the cuff and upper traps.
• Prolonged static posture
Keeping the shoulder in the same position for long periods can make the tendon feel stiff or achy when moving again.
• One-sided working patterns
Always using the same hand for the mouse, or reaching repeatedly to one side, overloads the already sensitive shoulder.
These small, repeated demands can increase irritation and slow recovery.
Most people with rotator cuff tendinitis or small tears benefit from gentle, controlled movement and reduced mechanical demand on the shoulder, without forcing painful ranges or lifting overhead.
1. Bring the work closer
Keep the mouse and keyboard close to the body so the elbow stays near your side.
A compact keyboard can help prevent reaching or rotating the shoulder outward.
2. Relax the shoulder position
Adjust the chair height so the shoulders can stay relaxed, not elevated.
Support the forearm on the desk or armrest if this feels more comfortable and reduces load on the cuff.
3. Use gentle, pain-free mobility
Safe options (if comfortable and non-provocative) include:
These movements should feel light and easy, never forced.
4. Break up long periods of stillness
Short posture changes every 20–30 minutes reduce stiffness and irritation in the tendon.
Even standing for a minute or gently changing arm position can help.
5. Avoid positions that overload the shoulder
If the shoulder is painful:
These adjustments help keep symptoms steadier and prevent flare-ups.
Rotator cuff tendinitis or small tears can be very manageable with the right workplace habits. Reducing reaching, supporting the arm, and using gentle, symptom-guided movement can ease irritation and promote smoother recovery. These small adjustments help the shoulder cope better with daily demands and reduce the risk of recurrent flare-ups.
