1. Borini, Cyntia Bicalho. Analise eletromiografica de musculos mastigatorios : variabilidade e influencia da ansiedade: Electromyographic analysis of masticatory muscles : variability and influence of anxiety.

Degree: 2008, Universidade Estadual de Campinas

Abstract: The aim of this study was to evaluate the interday and intraday variability in the values of electromyographic recordings of the superficial part of the masseter muscle and anterior part of the temporal muscle. Besides, it also purposed to verify the relationship of these recordings with the emotional factors, anxiety, at three different days of data collection. Sixteen volunteers, free of signs and symptoms of temporomandibular desorder, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were selected. Cephalometric measurements in lateral teleradiographs were used to classify the subjects into Class I and II, according to the relationship of maxillo-mandibular bone bases and regarding considering the vertical dimensions of the face into distinct mesofacial and dolicofacial types. To measure anxiety, the State-Trait Anxiety Inventory (STAI) was used. The electromyographic exam was carried out with Myosystem Br 1â electromyograph of 12 channels, with a resolution of 12 bites and gain up to 50 times, sampling frequency of 4000 Hz, bipolar passive electrodes coupled to a pre-amplifier with 20 times gain. The tasks of simultaneous bilateral chewing, habitual chewing and voluntary contraction in maximum intercuspidation were performed, at three different days, with interval of one week among them, and three repetitions on each day. The electromyographic signals were processed and normalized, and then the electrical activity of assessed muscles during the tasks were calculated through the instant maximum (Imax) and the time of activation (ON) the software Matlab version 5.3. As results, there was a variability between the comparison of the average of variable ON of the right masseter muscle in the habitual chewing on the various days of collection (p=0.02). While evaluating simultaneous bilateral chewing variability between the comparison of the average of variable ON of the anterior part of the right temporal muscle in the various repetitions (p=0.03). Given the variability shown by these muscles, there is a need to evaluate the electromyographic records both in habitual chewing and in the simultaneous bilateral chewing of these muscles in more than one session and more than one repetition. Regarding to anxiety, the results showed a reverse association between the variable activation time and the levels of trait-anxiety during the two tasks, and a direct association between the variable Imax and the levels of trait-anxiety during the two tasks. Only the anterior part of the temporal muscle during habitual chewing presented a direct relationship between the variable Imax and state-anxiety; and during simultaneous bilateral chewing the variable ON showed a reverse relationship for the same muscle. Thus it was concluded that the trait and state anxiety can influence electromyographic records, even in non-experimental situations.
