“…Landulpho et al 20 analyzed the EMG activity of the masseter and temporalis muscles before, during and after treatment with the device on the occlusal plane surface and concluded that there was a decrease in the electromyographic activity of the temporalis muscle during the evaluation periods proposed in this study. Those data are not in agreement with the results of this study, wherein the electromyographic activity of the temporalis muscle increased in most of the clinical situations analyzed.…”

Abstract:The Lucia jig is a technique that promotes neuromuscular reprogramming of the masticatory system and allows the stabilization of the mandible without the interference of dental contacts, maintaining the mandible position in harmonic condition with the musculature in normal subjects or in patients with temporomandibular dysfunction (TMD).This study aimed to electromyographically analyze the activity (RMS) of the masseter and temporal muscles in normal subjects (control group) during the use of an anterior programming device, the Lucia jig, in place for 0, 5, 10, 20 and 30 minutes to demonstrate its effect on the stomatognathic system. Forty-two healthy dentate individuals (aged 21 to 40 years) with normal occlusion and without parafunctional habits or temporomandibular dysfunction (RDC/TMD) were evaluated on the basis of the electromyographic activity of the masseter and temporal muscles before placement of a neuromuscular re-programming device, the Lucia jig, on the upper central incisors. There were no statistically significant differences (p < 0.05) in the electromyographic activity of the masticatory muscles in the different time periods. The Lucia jig changed the electromyographic activity by promoting a neuromuscular reprogramming. In most of the time periods, it decreased the activation of the masticatory muscles, showing that this device has wide applicability in dentistry. The use of a Lucia jig over 0, 5, 10, 15, 20 and 30 minutes did not promote any statistically significant increase in muscle activity despite differences in the data, thus showing that this intra-oral device can be used in dentistry.

A DTM foi diagnosticada pelo critério de diagnóstico em pesquisa para DTM (Research Diagnostic Criteria for Temporomandibular Disorders). A eletromiografia dos músculos esternocleidomastoídeo (ECOM) e trapézio superior foi realizada bilateralmente, na situação de repouso, com frequência de 2 KHz e filtro passa-faixa de 10-1000 Hz. As medidas de ADM de flexão, extensão, lateroflexão e rotação foram realizadas com um flexímetro e a comparação entre os grupos contou com o teste de Mann Whitney. O teste de Spearman foi aplicado para a correlação entre as variáveis, com nível de significância de 5%. Não foi verificada nenhuma diferença na ADM cervical entre os grupos. A atividade elétrica demonstrou-se significativamente maior nos músculos ECOM direito (p=0,0130), trapézio superior direito (p=0,0334) e esquerdo (p=0,0335) no grupo DTM em relação ao grupo controle. Não houve correlação significante entre atividade elétrica e ADM cervical. A dor nos músculos cervicais apresentou-se significativamente maior apenas no músculo ECOM direito (p=0,0055). Conclui-se que os grupos estudados registraram diferença na atividade elétrica dos músculos cervicais, sendo esta maior em indivíduos com DTM. DEScRitORES: transtornos da articulação temporomandibular; eletromiografia; amplitude de movimento articular.ABStRAct: The aim of the research was to evaluate the electrical activity and pain on palpation of the cervical muscles, the cervical range of motion (ROM) and the relationship between electrical activity and ROM in individuals with and without temporomandibular disorder (TMD). Fifty three volunteers took part in the study, being 24 with TMD and 29 without, both genders, from 18 to 32 years old. The TMD was diagnosed through Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD). The electromyografhy of Sternocleidomastoideus (SCM) and upper trapezius muscles was carried out bilaterally during rest situation, with a frequency of 2 KHz and band-pass filter of 10-1000Hz. The measures of flexion, extension, lateral tilt and rotation ROM were acquired through a fleximeter and the comparison between groups was analyzed by Mann-Whitney test. The Spearman test verified the correlation between the variables, with 5% of significance level. There were no differences in the cervical ROM between the groups. The electrical activity was significantly higher in the right SCM (p=0,0130), left (p=0,0335) and right (p=0,0334) trapezius muscles in the TMD group. There were no significant correlations between electrical activity and cervical ROM. Pain in the neck muscles was significantly higher only in the right SCM (p=0,0055). It is concluded that the studied groups had difference in the electrical activity of the cervical muscles, which was larger in the individuals with TMD.

“…The volunteers indicated the PPT by elevating hand when they have had identified painful sensation. Three measurements were made at each visit, with a 5-minute rest interval between trials [20] and the first pressured point was randomized selected. The PPT was calculated by averaging the 3 measurements.…”

The aim is to evaluate the influence of oral contraceptive intake and menstrual cycle on the electrical activity and pressure pain threshold from anterior temporal and masseter muscles. Twenty-eight women on reproductive age were selected, 13 OC users and 15 nonusers. They were weekly submitted to electromyography and algometry of the anterior temporal and masseter muscles during three consecutive menstrual cycles. Electrical activities at rest position and PPTs of temporal and masseter muscles were not affected by menstrual cycle or by OCs uses. Comparison between groups demonstrated that working side electrical activity was increased in OC users in both muscles, except during lutheal phase for the anterior temporal. However, comparison within weeks did not demonstrate statistical difference. It was suggested that, in healthy women, oral contraceptive use may influence electrical activity, but different phases of the cycle may not.
