Official title
Is Bruxism Associated With Altered Systemic Neuromuscular Function and Increased Risk of Muscular Injury ?
Overview
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.
Primary outcome measures
- Muscular Tone [Time frame: Baseline]
- Dynamic Stiffness [Time frame: Baseline]
- Muscular elasticity [Time frame: Baseline]
- Muscular Mechanical Stress Relaxation Time [Time frame: Baseline]
- Muscular Creep [Time frame: Baseline]
- Maximal grip strength test [Time frame: Baseline]
- Muscle fatigue [Time frame: Baseline]
- Trapeze isometric force [Time frame: Baseline]
- Muscular Tone [Time frame: 15-30 minutes after training]
- Dynamic Stiffness [Time frame: 15-30 minutes after training]
Secondary outcome measures (4)
- Shoulder - passive range of motion [Time frame: Baseline]
- Cervical spine mobility [Time frame: Baseline]
- Athletic performance [Time frame: Baseline]
- History of sports injuries [Time frame: Baseline]
