Accuracy of the surface electromyography RMS processing for the diagnosis of myogenous temporomandibular disorder

摘要: Due to the multifactor etiology of temporomandibular disorder (TMD), precise diagnosis remains a matter debate and validated diagnostic tools are needed. The aim was determine accuracy surface electromyography (sEMG) activity, assessed in amplitude domain by root mean square (RMS), TMD. One hundred twenty-three volunteers were evaluated using Research Diagnostic Criteria for Temporomandibular Disorders distributed into two groups: women with myogenous TMD (n = 80) without 43). then submitted sEMG evaluation anterior temporalis, masseter suprahyoid muscles at rest during maximum voluntary teeth clenching (MVC) on parafilm. accuracy, sensitivity specificity muscle activity analyzed. Differences between groups found all analyzed as well MVC Moderate (AUC: 0.74–0.84) RMS regarding Moreover, ranging from 71.3% 80% 60.5% 76.6%. In contrast, did not exhibit acceptable degrees other masticatory It concluded that is complementary tool clinical
