This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing two common treatments—a heat pad and a percussion massage gun—to see which one works better at reducing stiffness in your masseter muscle, which is the muscle you use to chew. Researchers will measure muscle stiffness using ultrasound before and after each treatment. The goal is to understand whether these simple, non-invasive therapies can improve how your jaw muscle feels and functions.
Jaw muscle stiffness can affect chewing ability and comfort, but doctors don't yet have clear evidence about which simple treatments work best. This study aims to compare heat and massage therapy to find the most effective approach for loosening tight jaw muscles.

You will visit the clinic twice, with two weeks between visits. At each visit, researchers will measure your jaw muscle stiffness using ultrasound and test your mouth opening, muscle sensitivity, bite force, and chewing ability. Then you'll receive one treatment: either a 2-minute massage gun session or a 20-minute heat pad treatment held in place with a strap. All tests will be repeated after the treatment. Each participant receives both treatments in different orders depending on their group assignment.
