Evaluation of the Effects of Physiotherapy and Rehabilitation Interventions in Patients With Bruxism

Bruxism is a multifactorial condition that affects the masticatory muscles and often requires multidisciplinary management. This study aimed to investigate and compare the effects of manual therapy and home exercise on pain intensity, number of myofascial trigger points, temporomandibular joint (TMJ) and cervical mobility, head posture, muscle thickness, stiffness, and activity in individuals with bruxism. Methods: Thirty individuals diagnosed with bruxism were randomly assigned to two intervention groups: the Home Exercise Group (HEG) and the Manual Therapy Group (MTG). All participants received education about bruxism. The HEG performed a supervised home-based exercise program three times per week for eight weeks, supported by instructional videos and weekly follow-up. The MTG received intraoral and extraoral manual therapy targeting the jaw and cervical regions twice a week over the same period. Pain intensity (Visual Analog Scale), trigger point count (palpation), TMJ mobility (ruler), head posture and cervical mobility (goniometer), muscle thickness and stiffness (ultrasound), and muscle activity (electromyography) were evaluated before and after treatment.
