Summary

This study tested two treatments for partial tears of the shoulder tendon: platelet-rich plasma (PRP) injections and a home exercise program. Forty adults with chronic shoulder pain received either three PRP shots or did exercises at home. Researchers measured pain, movement, and function two months after treatment to see which approach worked better.
