Causes
Tendinopathy is generally caused by overuse of a muscle-tendon unit. Over time, the strain on the tendon causes structural changes within the tendon itself.
Shoulder tendons are overused most often with:
- Repeated reaching overhead
- Repeated throwing
Bicipital tendinopathy is linked to rotator cuff conditions. Rotator cuff tendinopathy may result from wear and tear with age.
Risk Factors
Factors that increase your chance of developing shoulder tendinopathy include:
- Age: 30 and over
-
Always using the arm in an overhead position or throwing motion, as in:
- Tennis or other racquet sports
- Swimming
- Baseball
- Jobs (eg, overhead assembly work, butchering, or using an overhead pressing machine)
