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.

2. Pedroni, Cristiane Rodrigues. Contribução diagnostica da eletromiografia de superficie para a disfunção temporomandibular: Diagnosis contribuition of surface electromyography for temporomandibular disorders.

Degree: 2007, Universidade Estadual de Campinas

Abstract: Surface electromyography (SEMG) has been consistently used by clinicians and researchers to assess muscular function. SEMG is considered an important instrument in the evaluation of muscular conditions in Temporomandibular Disorder (TMD) patients. However, it does not seem to be able to determine the presence of dysfunction because it is limited in terms of reliability, validity, sensibility and specificity. The aim of this study was to compare the SEMG of the temporalis anterior and masseter muscles in subjects classified by the Research Criteria Diagnosis for Temporomandibular Disorders (RDC/TMD) Axis I, and to find a measure that could better distinguish between TMD and non-TMD subjects. Once such a measure was found, the objective was to verify SEMG validity to diagnose TMD. Sixty-one female volunteers aged between 18 and 36 (23,3 ± 8,2) participated in this experiment. The volunteers were divided into two groups, namely TMD and control. The TMD group comprised 36 myogenic TMD patients and the control group consisted of 25 non-TMD subjects. The EMG records were obtained using the Myosystem BR-1 equipment with 12 channels, 12-bit resolution, and gain of 50 times. Differential surface electrodes (pure silver, gain 100) were used. The software Myosystem BR-1 3.0 version was employed to visualize and process the SEMG signal, with a frequency sample rate of 2000 Hz and digital band-pass filter of 10-500 Hz. The signals were then analyzed according to measures of Root Mean Square (RMS), Integral of Envelope Linear and Median Frequency. Maximal biting and bilateral chewing were assessed. The results were observed in relation to mean, standard deviation, coefficient of variation and angular coefficient of the linear regression, which were obtained from three epochs in each signal during the recorded period. Analysis of Variance (ANOVA) was used to assess the difference between groups, and Discriminant Analysis to test the diagnostic validity of SEMG. The mean of envelope linear values during dynamic contractions of the temporal muscle was different between groups (p<0,03), and the angular coefficient of the linear regression to RMS values was different during isometric (p<0,04) and isotonic (p<0,05) contractions in the same muscle. The sensibility values ranged from 80,6% to 84,3%, the specificity values ranged from 66,6% to 76% and predictive positive values ranged from 72,2% to75%%. Based on the findings, the SEMG of temporal anterior and masseter muscles is able to differentiate TMD and non-TMD subjects when the mean of envelope linear values during dynamic contractions is observed, and when the angular coefficient of linear regression for RMS values in static and dynamic contractions is examined. Nevertheless, the validity of SEMG as a diagnostic instrument for the TMD condition could not be corroborated in this study Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Bérzin, Fausto, 1940- (advisor), Universidade Estadual de Campinas.
