Summary
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.
