Influence of craniomandibular and cervical pain on the activity of masticatory muscles in individuals with Temporomandibular Disorder

PURPOSE This study aimed to establish the prevalence of pain in the craniomandibular and cervical spine region in individuals with Temporomandibular Disorders (TMD) and to analyze the effects of these disorders on the bilateral activation of anterior temporalis (AT) and masseter (MA) muscles during the masticatory cycle. METHODS The participants were 55 female volunteers aged 18-30 years. The presence of TMD and craniomandibular and cervical spine pain was evaluated by applying the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire and using a combination of tests for the cervical region. The muscle activity of AT and MA during the masticatory cycle was assessed using the symmetry and antero-posterior coefficient indices. RESULTS The AT activity during the masticatory cycle is more asymmetric in individuals with TMD. The craniomandibular pain, more prevalent in these individuals, influenced these results. CONCLUSION Individuals with TMD showed changes in the pattern activity of AT. The craniomandibular nociceptive inputs can influence the increase in asymmetry of the activation of this muscle.

Influence of flexibility and gender on the posture of school children

Objetivo:Verificar se a flexibilidade e o sexo exercem influencia sobre a postura de escolares.Metodo:Foram avaliados 60 escolares de ambos os sexos, com idade entre 5 e 14 anos, divididos em dois grupos: flexibilidade normal (n=21) e flexibilidade reduzida (n=39). A flexibilidade e a postura foram avaliadas, respectivamente, por meio da fotogrametria e do teste de elevacao dos membros inferiores em extensao, considerando o ângulo da perna e a avaliacao postural. Para o tratamento de dados, foi feita a estatistica descritiva (media e desvio padrao). A analise de variância univariada (ANOVA) foi utilizada para verificar a influencia conjunta dos fatores flexibilidade e sexo nas variaveis dependentes posturais. Apos verificar efeito interativo entre esses dois fatores, procederam-se as comparacoes multiplas, utilizando o teste t.Resultados:A variavel flexibilidade exerceu efeito sobre o ângulo de simetria do joelho (p 0,05). Houve interacao entre as variaveis flexibilidade e sexo no ângulo de simetria do joelho (p<0,02). Escolares do sexo masculino e flexibilidade reduzida apresentaram maior assimetria de joelho, comparados aos outros subgrupos.Conclusao:A postura sofreu efeito isolado da variavel flexibilidade e efeito interativo entre o sexo e a flexibilidade.

Efeito do tempo de contração e repouso na atividade dos músculos masseter e temporal anterior em indivíduos com DTM

Purpose The main objective of this study was to investigate the effect of time of contraction and rest on the masseter and temporal muscles activity. Methods 49 female subjects between 18 and 30 years of age were divided into TMD (n: 26) and control groups (n: 23). Surface electromyograph was used to evaluate the anterior temporal and masseter muscles during contraction and rest protocols. The root means square, median frequency and slope coefficient of the linear regression line parameters were analyzed. Results A significant effect of time in the contraction and rest muscle protocols was found. TMD patients showed a significant decrease in median frequency in the right masseter muscle and the slope coefficient in the right temporal muscle during the contraction protocol to control subjects. Conclusion Despite the TMD patients presented with higher fatigue susceptibility compared to the control group, both groups must meet the maximum time of 5 s of maximum voluntary contraction and at least 30 s rest between successive contractions of masticatory muscles during clinical or research assessment protocols.

Influence of nutritional status and physical activity on the posture of children and ­adolescents

El objetivo del estudio fue verificar el efecto del perfil nutricional y de la actividad fisica en la postura de ninos y adolescentes. Fueron evaluados 60 individuos de ambos sexos, con edades entre 5 y 14 anos. La postura fue evaluada por medio de fotogrametria. Para determinar el nivel de actividad fisica fue utilizado el Cuestionario de Actividad Fisica para ninos (PAQ-C). La clasificacion del perfil nutricional fue realizada por medio del Indice de Masa Corporal por edad y con relacion al sexo. Los resultados mostraron que la actividad fisica ejerce un efecto sobre los angulos de asimetria del hombro (AH) y asimetria corporal (ACO) (p<0,05). El grupo activo presento mayor asimetria en los angulos AH y ACO comparado al grupo sedentario (p<0,05). El perfil nutricional no influencio ningun angulo postural (p<0,05). Tambien no hubo efecto interactivo entre los parametros evaluados sobre los angulos posturales (p<0,05). Es importante el desenvolvimiento de acciones preventivas e intervenciones, como la actividad fisica controlada y acompanamiento nutricional, en el alineamiento postural de ninos y adolescentes en edad escolar.The purpose of this study was to verify the effect of nutritional status and physical activity on the posture of children and adolescents. Sixty individuals from both genders aged between 5 years and 14 years were evaluated. The posture was assessed by photogrammetry. The physical activity level was determined through the Physical Activity Questionnaire for Children (PAQ-C). The nutritional status classification was made using the body mass index for age and gender. The results showed that the physical activity variable had an effect on the shoulder and body asymmetry angles (p 0.05). There was no interactive effect between the evaluated variables on the postural angles (p>0.05). The development of preventive and interventionist actions, such as controlled physical activity and nutritional monitoring, is important for the postural alignment of school children and school adolescents.

Motor behavior of masticatory muscles in individuals with unilateral trans-incisive foramen cleft lip and palate*

Abstract Objective: To investigate whether children with complete unilateral cleft lip and palate (CLP) have altered control of masticatory muscles. Methods: The muscular activity of 66 children with CLP (n = 33) and without CLP (n = 33), aged 6–12 years was assessed during different tasks (rest, isometry, mastication) using electromyography. Results: The activation for the analyzed muscles was higher in children with CLP at rest (R) and inactive period (IP) (p < 0.05). The muscles of children with CLP remained active for longer than those without CLP (p < 0.05), and the length of the masticatory cycle was higher in children with CLP (p < 0.05). Conclusion: Children with CLP have longer muscle activation and increased cycle time during the chewing cycle, which might be a consequence of malocclusion, resulting in difficulty chewing.

Temporomandibular dysfunction, myofascial, craniomandibular and cervical pain: effect on masticatory activity during rest and mandibular isometry

BACKGROUND AND OBJECTIVES: Craniomandibular and cervical symptoms interfere with mandibular stability. Determining whether these disorders influence muscle activation when chewing, it is possible to improve interventions for this population. The objective of this study was to verify the effect of the temporomandibular joint dysfunction, craniomandibular and cervical pain on the electromyographic activity of the masticatory muscles during rest and mandibular isometry. METHODS: Fifty-five women aged between 18 and 30 years were divided into two groups: with temporomandibular dysfunction (n=28) and without temporomandibular dysfunction (n=27). The diagnosis of temporomandibular dysfunction was established using the Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD). The RDC was also used to determine the presence of craniomandibular pain. Cervical pain was defined by physical examination. The electromyographic activity of masseter and temporalis muscles was evaluated in the rest position and mandibular isometry. The amplitude of muscle activation was represented by the root mean square values (RMS%) and normalized by maximum voluntary contraction. The Mann-Whitney U test was used to detect differences between the groups with and without temporomandibular dysfunction; with and without myofascial craniomandibular pain; and with and without cervical myofascial pain. RESULTS: It was observed greater amplitude in the activation of masseter and right temporalis muscles in the rest position in individuals with myofascial craniomandibular pain compared to asymptomatic (p<0.05). There was no difference among individuals with and without cervical myofascial pain, and with and without temporomandibular dysfunction. CONCLUSION: The presence of myofascial craniomandibular pain did not affect the masticatory activity, with greater muscle activation in mandibular rest.

Efeito do Sedentarismo, Perfil Nutricional e Sexo na Flexibilidade de Escolares

Introduction: assart-day life habits have led to a more sedentary lifestyle, contributing to increased obesity. In view of these changes, it is necessary to understand whether the flexibility of the individual has also been influenced. Objective: to investigate the influence of sex, sedentary lifestyle and nutritional status on the flexibility of elementary school children. Methods: 60 cheldren of both sexes aged five to 14 years were divided into a normal flexibility group (n = 21) and a reduced flexibility group (n = 39). Flexibility was evaluated by photogrammetry using the straight leg raise test, considering the leg angle. The physical activity level was evaluated using the Physical Activity Questionnaire for Older Children, and nutritional status was assessed by Body Mass Index for age and sex. Results: the normal flexibility group and the reduced flexibility group presented no significant differences regarding age, weight or height (p > 0.05). No differences were found (p > 0.05) in leg angle between the active and sedentary groups, the obese and nonobese or between males and females. Conclusions: sex, sedentary lifestyle and nutritional status exercized to influence on the flexibility of students.
