Targeted eccentric exercise may rebuild shoulder function — a trial puts it to the test

This trial investigates whether eccentric isokinetic exercise — a type of controlled, lengthening muscle contraction performed on a special machine — can reduce pain and improve shoulder function in people with rotator cuff tendinopathy. Fifty adults aged 20 to 50 with confirmed tendinopathy will either do this machine-based exercise plus a standard home program, or the home program alone. Researchers will measure changes in pain, shoulder function, and muscle structure using ultrasound.
