Development and Validation of an MRI-Compatible Jaw Metabolic Stressor Task_Study1

The goal of this study is to develop and test a new way of measuring how much effort and strain the jaw muscles can handle before a person begins to feel specific levels of pain or fatigue. This involves a controlled jaw exercise task designed to better understand the relationship between jaw muscle effort, physical stress in the muscles, and how each person experiences discomfort. It is hoped that the information learned in this study will help researchers refine this new jaw testing method and confirm whether it accurately measures jaw muscle effort and discomfort. This may support future research that improves how jaw pain conditions are understood and eventually lead to better, more individualized treatments for people with jaw muscle and jaw joint disorders.
