【 摘 要 】

BACKGROUND: recent studies have used ultrasonography with the purpose of measuring muscle cuts. AIM: to characterize the motor control and the morphology of the masseter muscle in normal individuals, verifying the compatibility between surface electromyography and ultrasonography. METHOD: five adult individuals, with no alterations of the stomatognathic system. The adopted assessment procedures for all participants were: 1. Surface Electromyography; 2. Ultrasonography. RESULTS: a high correlation was observed only when comparing both hemifaces in the ultrasonographic assessment (rest 0.95; biting 0.86). CONCLUSION: the results indicate that there is no correlation between the tested methods, suggesting that both methods are complementary and not mutually excludent.
