Neuromuscular Function and Performance in Athletes With or Without Bruxism

Is Bruxism Associated With Altered Systemic Neuromuscular Function and Increased Risk of Muscular Injury ?

The aim of this study is to evaluate the associations between bruxism and neuromuscular function, as well as athletic performance, in a population of amateur athletes. Particular attention will be paid to musculoskeletal disorders associated with bruxism, particularly in the shoulder. Participants' history of sports injuries will also be recorded. To control for the effect of potential confounding variables, levels of stress, anxiety, and mood, as well as sleep quality, will be systematically measured using validated questionnaires.
