Light therapy tested as new way to soothe jaw pain

This study tests whether a special light therapy (photobiomodulation) can reduce pain and improve jaw function in people with myofascial temporomandibular disorder (TMD), a condition causing muscle pain in the face and jaw. About 140 adults will be split into three groups: light therapy alone, light therapy plus exercises, or a fake light treatment plus exercises. The goal is to see if adding light therapy provides extra pain relief beyond exercises alone.
