What this Trial Is About
The purpose of this study is to evaluate the changes in the stiffness of the masseter muscle (a jaw muscle) before and after two types of treatment: applying commercial heat pads or using a commercial massage gun. We will measure the muscle stiffness on the surface of the muscle using a special ultrasound probe, with a method called shear wave elastography. When this muscle is too stiff, it's often linked to jaw pain and problems with the jaw joint - a condition known as Temporomandibular Disorder (TMD). The goal is to find better treatment options for people with TMD and to collect data using this imaging technique.
