Summary

This study looks at whether bruxism (teeth grinding) is linked to changes in muscle function and a higher risk of injuries, especially in the shoulder, among amateur athletes. Researchers will measure muscle tone, stiffness, and strength in 120 swimmers and handball players. The goal is to better understand how bruxism might affect overall body health and athletic performance.
