Electrical Stimulation of the Mandibular Nerve to Manage Pain and Improve Jaw Function in Adults with Temporomandibular Disorders

What this Trial Is About

Temporomandibular disorders TMD cause pain and dysfunction in the jaw muscles and joint, affecting daily activities like eating, speaking, and yawning. These disorders are common, impacting 60% to 70% of people, with up to 12% experiencing severe symptoms needing treatment. This research evaluates the use of percutaneous electrical nerve stimulation PENS, a minimally invasive therapy, targeting the mandibular nerve to manage pain and improve function in TMD patients. Participants will be randomly assigned to one of two groups one receiving manual therapy, exercise, and PENS, and the other receiving manual therapy and exercise only. PENS involves inserting a dry needling needle near the nerve and applying electrical stimulation to reduce pain perception. Manual therapy uses digital pressure to ease muscle stiffness and pain, while exercises aim to improve jaw movement and muscle tone. Treatments occur across multiple intervention sessions. During the study, participants pain intensity, pressure pain thresholds, and pain-free jaw opening range will be measured at each sessions start and one month after the final treatment. Secondary evaluations include quality of life and muscle activation rates. The study includes assessments like physical exams and questionnaires to monitor progress and safety. Participation lasts from screening through intervention and follow-up, up to one month post-treatment.
