Eletromiografia dos músculos mastigatórios: análise em valor original e RMS

Abstract: Objetivo comparar a atividade elétrica dos músculos masseter e temporal, porção anterior, no repouso, contração isométrica voluntária máxima e na mastigação em análise valor original (µv) e em Root Mean Square (RMS). Métodos estudo observacional, descritivo. Foi realizado eletromiografia de superfície nos músculos masseter e temporal, porção anterior, bilateralmente, em 18 mulheres entre 27 e 50 anos de idade. O exame foi realizado em três situações: durante o repouso, na contração isométrica voluntária má… Show more

“…Data exported by the recording device included details of muscle activity in a resting position, tonic contractions, phasic contractions, mastication, swallowing, speech, teeth clenching, soft grinding, heavy grinding, and jaw thrusting [38,39]. The data analysis is carried out by studying the connection between the intensity and the frequency of the recorded electrical activity and the duration [40].…”

“…O envelhecimento é um processo natural, progressivo e biológico. Assim, não se deve fazer associação desse termo sempre com doença ou inatividade 15 , pois é diferente em cada indivíduo e depende do estilo de vida e das características biológicas de cada ser 16 . Nos aspectos biológicos devemos levar em consideração que ocorre uma alteração celular, molecular, tecidual e orgânico 17 .…”

“…Frequency spectrum was verified by Fast Fourier Transform (FFT) to identify noise and the signal artifacts. After rectifying the signal, the values were obtained in root mean square (RMS) (20) , by using MiotecSuite  . Values for the three MVCs in RMS were determined, in addition to the resting value, which was obtained before the contractions.…”
