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.
