Electromyographic evaluation of the effect of ultrasound with muscle stretching in temporomandibular disorder: a clinical trial

AIM: To investigate the electromyographic activity of masticatory muscles in women with myogenic or mixed TMD treated with ultrasound and ultrasound associated with stretching. METHODS: Sixteen women with myogenic or mixed TMD, according to the Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD), participated in the study. The patients were evaluated using surface electromyography (sEMG) of the masseter and anterior temporalis muscles, during maximum intercuspation, before and immediately after application of therapeutic resources. All patients were treated by ultrasoun...
