Summary

This study looks at whether adding a simple nerve-stimulation technique (using deep breathing to activate the vagus nerve) to standard physical therapy can better reduce pain and improve jaw movement in people with jaw joint disorders. Sixty adults with jaw muscle pain will receive either physical therapy alone or physical therapy plus the nerve stimulation over four sessions. The goal is to see if the combined approach leads to greater pain relief and better quality of life.
