PURPOSE: To study the frequency of cervical spine dysfunction (CCD) signs and symptoms in subjects with and without temporomandibular disorder (TMD) and to assess the craniocervical posture influence on TMD and CCD coexistence. METHODS: Participants were 71 women (19 to 35 years), assessed about TMD presence; 34 constituted the TMD group (G1) and 37 comprised the group without TMD (G2). The CCD was evaluated through the Craniocervical Dysfunction Index and the Cervical Mobility Index. Subjects were also questioned about cervical pain. Craniocervical posture was assessed by cephalometric analysis. RESULTS: There was no difference in the craniocervical posture between groups. G2 presented more mild CCD frequency and less moderate and severe CCD frequency (p=0.01). G1 presented higher percentage of pain during movements (p=0.03) and pain during cervical muscles palpation (p=0.01) compared to G2. Most of the TMD patients (88.24%) related cervical pain with significant difference when compared to G2 (p=0.00). CONCLUSION: Craniocervical posture assessment showed no difference between groups, suggesting that postural alterations could be more related to the CCD. Presence of TMD resulted in higher frequency of cervical pain symptom. Thus the coexistence of CCD and TMD signs and symptoms appear to be more related to the common innervations of the trigeminocervical complex and hyperalgesia of the TMD patients than to craniocervical posture deviations.

BackgroundPulmonary function (PF) trajectories are determined by different exposures throughout the life course. The aim of this study was to investigate characteristics related to PF trajectories from 15 to 22 years in a Brazilian cohort.MethodsA birth cohort study (1993 Pelotas Birth Cohort) was conducted with spirometry at 15, 18 and 22 years. PF trajectories were built based on z-score of forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and their ratio using a group-based trajectory model. Associations with exposures reported from perinatal to 22 years were described.ResultsThree trajectories, low (LT), average (AT) and high (HT) were identified in 2917 individuals. Wealthiest individuals belonged to the HT of FEV1 (p=0.023). Lower maternal pregestational body mass index (BMI) (22.4±0.2; p<0.001 and 22.1±0.14; p<0.001) and lower birth weight (3164.8±25.4; p=0.029 and 3132.3±19.4; p=0.005) were related to the LT of FEV1 and FVC. Mother's smoking exposure during pregnancy (37.7%; p=0.002), active smoking at ages 18 and 22 years (20.1% and 25.8%; p<0.001) and family history of asthma (44.8%; p<0.001) were related to the LT of FEV1/FVC. Wheezing, asthma and hospitalisations due to respiratory diseases in childhood were related to the LT of both FEV1 and FEV1/FVC. Higher BMIs were related to the HT of FEV1 and FVC at all ages.ConclusionsPF trajectories were mainly related to income, pregestational BMI, birth weight, hospitalisation due to respiratory diseases in childhood, participant's BMI, report of wheezing, medical diagnosis and family history of asthma, gestational exposure to tobacco and current smoking status in adolescence and young adult age.

TMD presence resulted on a higher frequency of myofunctional alterations during masticatory and swallowing functions. A greater distance from hyoid bone to the mandible in addition with the presence of painful symptom can justify, partly, the atypical behaviors of the tongue and lips observed on TMD group. The TMD repercussion on alimentaires functions in a young age group justifies the importance of an earlier diagnosis and therapeutic intervention in these individuals.

Introduction Mouth breathing can affect the functions of the respiratory systems and quality of life. For this reason, children who grow up with this stimulus may have implications on physical and psychological aspects at adult age.Objective To evaluate childhood mouth-breathing consequences for the ventilatory function and quality of life at adult age.Materials and methods Prospective, observational and cross-sectional study with 24 adults, between 18 and 30 years old, mouth breathers during childhood, comprised the childhood mouth-breathing group (CMB). The childhood nasal-breathing (CNB) group was composed of 20 adults of the same age, without history of respiratory disease during all their lives. Measurements of maximal respiratory pressures, peak expiratory flow and 6-minute walk test were assessed. In addition, all the volunteers answered the Short Form-36 questionnaire (SF-36).Results The maximal inspiratory (p = 0.001) and expiratory (p = 0.000) pressures as well as the distance in the walk test (p = 0.003) were lower in the COB. The COB also presented lower score in the General Health domain of the SF-36 Questionnaire (p = 0.002).Conclusion Childhood mouth-breathing yields consequences for the ventilatory function at adult age, with lower respiratory muscle strength and functional exercise capacity. Conversely, the quality of life was little affected by the mouth breathing in this study.

| Neck pain is the most common symptom of cervical dysfunctions often being related to the maintenance of postures. Postural changes of the head are often associated with the occurrence of neck pain with an anterior approach was the most frequent. The purpose was to investigate the correlation between head posture, pain intensity and neck disability index. The study group (SG) was composed of women, aged between 20 and 50 years who complained of neck pain for more than three months, and the control group (CG) for asymptomatic women. Pain intensity was assessed by visual analogue scale (VAS), disability by neck disability index (NDI) and the head posture by the craniovertebral angle (CV). Normality of the data was verified by the Lilliefors test and the comparison between groups by the Student's t-test for independent samples, and the association between variables by Spearman correlation test. Significance level was 5%. The SG had lower average CV for the angle (p=0.02). The CV angle was negatively correlated with the VAS (r=-0.48) and NDI (r=-0.15) suggesting that the smaller the angle, the greater the intensity of neck pain and disability. The NDI and VAS showed a positive correlation (r=0.59). The angle CV in subjects with neck pain was significantly lower than in healthy individuals association with the neck disability index and pain.Keywords | neck pain; posture; head.RESUMO | A dor cervical é o sintoma mais comum das disfunções cervicais, frequentemente relacionado à manutenção de posturas inadequadas. As alterações posturais da cabeça estão associadas à ocorrência de dor cervical, sendo a anteriorização a alteração mais comum. O objetivo foi investigar a correlação entre postura da cabeça, intensidade da dor e índice de incapacidade cervical -neck disability index (NDI). O grupo estudo (GE) foi composto por mulheres na faixa entre 20 e 50 anos com queixas de dor cervical por mais de três meses, e o grupo controle (GC), por mulheres assintomáticas. A intensidade da dor foi avaliada pela escala visual analógica (EVA), a incapacidade pelo NDI e a postura da cabeça pelo ângulo craniovertebral (CV). A normalidade dos dados foi verificada pelo teste de Lilliefors, e a comparação entre os grupos pelo teste t de Student para amostras independentes e a associação entre as variáveis pela correlação de Spearman. O nível de significância foi de 5%. O GE apresentou mé-dias menores para o ângulo CV (p=0,02). O ângulo CV demonstrou correlação negativa com a EVA (r=-0,48) e o NDI (r=-0,15), sugerindo que quanto menor o ângulo, maior a intensidade da dor e a incapacidade cervical. O NDI e a EVA apresentaram correlação positiva (r=0,59). O ângulo CV em indivíduos com dor cervical foi significativamente menor que em assintomáticos, apresentando correlação moderada com o NDI e a dor.Descritores | cervicalgia; postura; cabeça.Correlação entre postura da cabeça, intensidade da dor e índice de incapacidade cervical em mulheres com queixa de dor cervical Correlation between head posture, pain and disability index neck in...

INTRODUÇÃO: Sabe-se que existe uma relação entre a Desordem Temporomandibular (DTM) e a postura craniocervical, porém, além de os estudos apresentarem resultados inconclusivos, a severidade dos sinais e sintomas de DTM não é considerada. OBJETIVO: Correlacionar índices de severidade da DTM com medidas cefalométricas craniocervicais. MATERIAIS E MÉTODOS: Participaram da pesquisa 32 mulheres entre 19 e 35 anos com diagnóstico de DTM (RDC/TMD). A severidade dos sinais e sintomas da DTM foi avaliada pelo Índice Temoromandibular proposto por Pehling, calculado com base nos achados do exame físico do RDC/TMD (eixo I). A postura craniocervical foi avaliada por cefalometria, por meio de 11 medidas referentes à posição da cabeça, coluna cervical, mandíbula e osso hioide. A normalidade dos dados foi testada pelo teste de Lilliefors e as correlações foram realizadas pelo coeficiente de Spearman. RESULTADOS: Foram encontradas correlações negativas e moderadas entre o ângulo CVT/Hor e os Índices Muscular (p = 0,0288) e Temporomandibular (p = 0,0394); entre o ângulo CPL/Hor (anteriorização) quando correlacionado aos Índices Funcional (p = 0,0482) e Muscular (p = 0,0086) e entre distância do hioide à terceira vértebra cervical (Hy/C3) e o Índice Funcional (p = 0,0155). CONCLUSÕES: Constatou-se associação entre a maior severidade do quadro clínico da DTM e a projeção anterior da cabeça, a flexão da coluna cervical baixa e a menor distância do osso hioide à terceira vértebra cervical. Essa relação sugere que as alterações posturais craniocervicais podem contribuir para a maior intensidade dos sinais e sintomas e perpetuação da DTM.

Este estudo objetivou avaliar o efeito da fisioterapia nos parâmetros ventilatórios e na dinâmica tóraco-abdominal de crianças respiradoras bucais. Dez crianças respiradoras bucais foram submetidas a um programa de reeducação respiratória e correção postural durante 20 sessões de exercícios de alongamento e fortalecimento muscular sobre a bola suíça, estimulação diafragmática e alongamento dos músculos acessórios da inspiração. Os dados coletados foram as medidas de pressões inspiratórias e expiratórias máximas (PIM e PEM), capacidade inspiratória (CI), pico de fluxo expiratório (PFE), mobilidade torácica por meio do coeficiente respiratório (Cr) nos níveis axilar (CrA), xifoide (CrX) e umbilical (CrU) e análise biofotogramétrica do ângulo de Charpy. Estes foram verificados antes e após 10 e 20 atendimentos. Os dados foram submetidos a uma análise de variância (ANOVA) e, nas diferenças encontradas entre as médias, aplicou-se o Teste de Tukey com nível de significância de 5% (p<0,05). Houve melhora para as medidas referentes ao ângulo de Charpy (p=0,048), CI (p=0,037), PFE (0,002), PIM (0,007), CrA (p=0,008) e CrX (p=0,041). A PEM e o CrU, apesar da melhora nos valores absolutos, não apresentaram resultados estatisticamente significativos. O programa de fisioterapia respiratória e postural produziu efeitos positivos sobre a função ventilatória de crianças respiradoras bucais.
