Summary

This observational study looked at 34 people who had reverse shoulder arthroplasty (a type of shoulder replacement) at least one year earlier. Researchers measured the strength and elasticity of the deltoid muscle in both the operated and healthy shoulders using special tests and ultrasound. They also asked participants to fill out questionnaires about how well their shoulder functions in daily life. The goal was to see how the replaced shoulder compares to the healthy one and whether strength, stiffness, and function are related.
