          Abstract

          OBJECTIVE: The objective of this paper was to evaluate the specificity of masseter muscle palpation when compared to its electromyographic activity. MATERIALS AND METHODS: Twenty-one young female adults, aged between 17 and 25, participated in this research. The speech therapy evaluation data were obtained by two speech therapists through masseter muscle palpation during isometric contraction, and the electromyographic exam was achieved by using bipolar superficial electrodes, positioned on the masseter muscle. The volunteers were instructed to chew the Parafilm M® material bilaterally and simultaneously. The capture of the electromiographic signals occurred during masseter muscle isometric contractions. The electrical activity study of the masticatory muscle was analyzed through the Root Mean Square value during its isotonic contraction. STATISTICAL ANALYSIS: All data were then submitted to Kappa statistical analysis. RESULTS: The results of this study have shown a low correlation between palpation and electromyography (25%), as well as between evaluators (40%). CONCLUSION: According to the findings of the present study, it could be observed that the correlation between masseter muscle palpation and its electromyographic activity was very low, which allows to conclude that muscular palpation cannot effectively replace the eletromyographical exam, but complement it instead.

          OBJETIVO: Este trabalho teve como objetivo avaliar a correlação entre os resultados obtidos na palpação e os dados obtidos no exame eletromiográfico do músculo masseter. MATERIAL E MÉTODO: Participaram deste estudo 21 adultos jovens do sexo feminino, idades entre 17-25 anos. Os dados da avaliação fonoaudiológica foram obtidos por meio da palpação do músculo masseter durante a contração isométrica por dois fonoaudiólogos e os dados eletromiográficos foram captados com a utilização de eletrodos de superfície bipolares posicionados no músculo masseter durante a contração isotônica, sendo os voluntários orientados a mastigar bilateral e simultaneamente o material Parafilme®.O estudo da atividade elétrica do músculo mastigatório foi analisado pelo valor de RMS (Root Mean Square) na contração isotônica do músculo. ANÁLISE ESTATÍSTICA: Todos os dados foram submetidos à análise estatística Kappa. RESULTADOS: Os resultados deste estudo indicaram baixa correlação entre a palpação e a eletromiografia (25%) e entre avaliadores (40%). CONCLUSÃO: a partir dos achados do presente estudo, que a correlação entre os dados obtidos na palpação do músculo masseter em relação aos dados obtidos no exame eletromiográfico foi muito baixa. Os resultados indicam que a palpação muscular não substitui o exame eletromiográfico, devendo complementá-lo.

            Electromyography: some methodological problems and issues.

            R. Türker (1993)
            The purpose of this review is to discuss electromyography (EMG) and some of the problems and issues that are encountered during the recording and interpretation of EMG data. Recordings of electrical activity of muscles can be contaminated by interference from the electrical supply, mechanical artifacts, stimulus artifacts, and activity of other muscles. The advantages and disadvantages of surface electromyography and intramuscular EMG are compared and contrasted, and precautions to be taken when recording and interpreting these data are described. Surface electromyography is usually more susceptible to artifacts than is intramuscular EMG. It is possible, however, to make useful recordings with the surface electrodes from large superficial muscles if appropriate precautions are observed. Intramuscular electrodes, on the other hand, may be preferred for recording the activity from small peripheral muscles or muscles located deep within the body.
