Summary

This study looks at whether teaching people with rotator cuff syndrome the best sleeping positions can improve their sleep quality while they undergo physical therapy. Researchers will compare two groups: one getting standard physical therapy, and another getting physical therapy plus sleep posture guidance. The goal is to see if better sleep positions can reduce pain and improve shoulder function over time.
