EMG Power Spectral Analysis of Masticatory Muscles in Patients with Maxillofacial Deformity

Abstract

The purpose of this study was to investigate the effect of tapping,gum chewing and muscle fatigue on the power spectrum and integration of the masticatory muscles EMG in 10 patients with mandibular prognathism(5 males and 5 females)and in 10 normal subjects(5 males and 5 females). Muscle fatigue in the anterior temporal and masseter muscles was induced by continuous maximum clenching in intercuspal position for 60 seconds.
