Exercise for rotator cuff tendinopathy.

Rotator cuff tendinopathy is among the main causes of shoulder pain. It is characterized by lesions without rupture caused by overload, work-related repetitive strain injury, or metabolic changes such as diabetes affecting one or more tendons, which cause pain, morphological alterations, and disability. This study aimed to evaluate the effects of exercise-based therapy on shoulder pain reduction and functioning improvement in patients with rotator cuff tendinopathy.
