Masseter Muscle Stiffness After Heat Application and Percussion Therapy

NCT07237087 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

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.
