“…Increasing evidence also shows that sEMG is useful in the differential diagnosis between healthy subjects and TMD patients [13, 14, 32]. With reference to individuals with TMD, there is to date no agreement on the normal values of basal muscle activity measured with sEMG at the level of ATs and MMs, with some authors suggesting increased values [17, 33] and others no difference [34, 35], in comparison to otherwise healthy subjects. These studies, however, do not take into account the possible concomitant presence of TTH in the examined subjects: therefore, a misclassification might have occurred by excluding individuals with TMD and concomitant TTH, thus including only low-tenderness, low-sEMG TMD individuals.…”

Background Tenderness of masseters and temporalis can be considered a relevant tool for diagnosis of myo-type craniofacial pain disorders, but a limit of pain score systems is that they are based on subjective pain perception. Surface electromyography (sEMG) is a noninvasive and reliable tool for recording muscle activity. Therefore, we investigated whether a correlation exists between tenderness on masseters and temporalis, assessed by subjective pain scale, and muscles activity, evaluated by sEMG, in patients with painful temporomandibular disorder (TMD) and concurrent tension-type headache (TTH). Methods A cross-sectional study on fifty adult volunteer patients with TMD and TTH, who underwent tenderness protocol according to Diagnostic Criteria for TMD (DC/TMD) guidelines, was conducted followed by sEMG recording of temporalis and masseters. Pearson's correlation was performed to investigate the correlation between muscular activity and subjective pain scores. Results An overall moderate correlation between muscle tenderness and sEMG values (y = 1 + 1.2 · x; r2 = 0.62; p < 0.0001), particularly in the temporalis, was observed. Segregation of data occurred according to tenderness and sEMG values. At the highest pain score, the mean sEMG absolute value was higher at the temporalis than the masseters. Conclusions Our study provides evidence that subjective pain perception can be objectively quantified at a magnitude proportional to pain severity. At greater tenderness scores, higher sEMG activity at the level of temporalis could help discriminate clinically prevalent TTH versus prevalent TMD. sEMG confirms to be an accurate tool to reliably objectify the subjective perception of pain. When combined with clinical evaluation and patients' symptoms, sEMG increases diagnostic sensitivity in the field of myo-type craniofacial pain disorders. This trial is registered with NCT02789085.

“…The anesthetic infiltration of lidocaine 2% and LLLT by GaAlAs showed to be ineffective to decrease the tenderness in posterior temporal muscle. This muscle is described as the most associated with facial pain in FM patients, with high patients’ complaint ( 26 ), what might be associated with the continuous activity function of temporalis muscle during the mandibular rest and elevation ( 31 ). Thus, the study of these treatments associated with the physiological function might be interesting to understand the muscle responsiveness in patients with FM.…”

BackgroundTo compare the analgesic effect of anesthetic infiltration of lidocaine 2% and low-level laser therapy (LLLT) by GaAlAs into tender points of patients with orofacial pain and fibromyalgia (FM).Material and MethodsA randomized clinical trial was performed with adults (N=66) that were allocated into two groups (1:1): Group A received LLLT irradiation by Diode Laser GaAlAs (780nm) with expositions twice a week during six weeks and Group B was treated with anesthetic infiltration of lidocaine 2% without vasoconstrictor once a week for four weeks. The pain assessment included the Visual Analogic Scale (VAS) and tenderness to palpation.ResultsNo dropout and adverse effect was observed during the study. The pain decreased significantly in each group after the treatment (p=0.0001, β=1.0), even though no statistical difference was found between both treatments (p=0.46, β= 0.82). The presence of tender points decreased after both treatments, with responsively in some types of masticatory muscles (p<0.05) except posterior temporalis muscle. The patients’ perception showed that both treatments were effective and a few patients reported that the treatment did not improve welfare.ConclusionsThe LLLT by GaAlAs and anesthetic infiltration of lidocaine 2% were equally effective to control orofacial pain in FM individuals. Key words:Facial pain, myalgia, rheumatic disease, local anesthesia, phototherapy.

“…35 Os casos de DTM também relataram níveis mais elevados de estresse psicológico e afetivo, maior estresse percebido e catastrofização e uma maior consciência somática em relação aos controles. 26 Achados similares que apoiam variá-veis psicossociais como fatores de risco pré-mórbidos para o desenvolvimento de dor crônica foram relatados para outras condiç ões de dor crônica, incluindo a dor crônica generalizada, ou seja, a fibromialgia.…”

“…Parece que os músculos prejudicados pela SFM podem já apresentar uma condição de interrupção prematura da contração muscular, a contração pode ter ocorrido ao se descarregarem as unidades motoras em frequências mais altas (contração tetânica) a fim de ativar a contração necessária, o que é ainda mais fatigante e leva a um ciclo de fadiga muscular e dor. 35 Elert et al 36 também sugerem que os pacientes com SFM têm uma incapacidade de relaxar os músculos de seu corpo entre as tarefas. Outro estudo relatou que os indivíduos com SFM apresentam uma velocidade de condução significativamente maior em cada unidade motora de contração do músculo trapézio, 37 ou seja, um maior número de unidades motoras ativas.…”

Diferenças na percepção da imagem corporal, no comportamento alimentar e no estado nutricional de universitárias das áreas de saúde e humanas Differences in body image perception, eating behavior and nutritional status of college students of health and human sciences Resumo Introdução: A literatura refere uma maior prevalência de transtornos alimentares em acadêmicas de cursos universitários nos quais a aparência física é importante, entre eles Educação Física e Nutrição. Supõe-se que pessoas preocupadas com seu peso e imagem corporal optem por essas áreas por terem um interesse pessoal pelo tema. O objetivo deste estudo foi avaliar a percepção da imagem corporal, o comportamento alimentar e o estado nutricional de estudantes de cursos das áreas da saúde e humanas para comparação entre estas. Método: Aplicou-se o Eating Attitudes Test (EAT-26) e o Body Shape Questionnaire (BSQ) em 127 alunas do primeiro ano dos cursos de Nutrição e Educação Física (Saúde) e de Publicidade e Propaganda e Administração de Empresas (Humanas) que forneceram dados de peso e altura para cálculo do índice de massa corporal. Resultados: Encontrou-se uma grande prevalência de distorção da imagem em todos os grupos, sem diferença entre as áreas ou entre os cursos. O EAT-26 indicou maiores escores nas estudantes da saúde em relação às de humanas, com alunas de Nutrição apresentando as maiores pontuações, estatisticamente diferentes das encontradas nos cursos de Publicidade e Administração, mas não de Educação Física. Além disso, a maioria das alunas foi classifi cada como eutrófi ca, e não se encontraram mulheres com obesidade em nenhum dos cursos, não havendo diferença signifi cativa entre áreas ou cursos para esta variável. Discussão: A alta incidência de distorção da imagem corporal associada à grande prevalência de comportamento alimentar inadequado nas alunas da área da saúde demonstra uma possível susceptibilidade ao desenvolvimento de transtornos alimentares. Descritores: Imagem corporal, comportamento alimentar, estado nutricional, estudantes, transtornos da alimentação. Abstract Introduction: The literature reports a higher prevalence of eating disorders among undergraduate students whose majors value physical appearance, including Physical Education and Nutrition. It is possible to assume that people concerned about their weight and body image may choose to take these majors because they are personally interested in the topic. The objective of this study was to assess the body image perception, eating behavior, and nutritional status of students of health and human sciences and to compare these data. Method: The Eating Attitudes Test (EAT-26) and the Body Shape Questionnaire (BSQ) were administered to 127 fi rst-year students of Nutrition and Physical Education (health sciences) and Advertising and Business Administration (human sciences) who also provided information on weight and height for calculation of their body mass index. Results: We found a high prevalence of body image distortion in all groups, with no difference betwee...
