Abstract Objective To assess the effects of three 8-week exercise programs on the frequency, intensity, and impact of headaches in patients with headache attributed to temporomandibular disorder (TMD). Methodology Thirty-six patients diagnosed with headache attributed to TMD participated in the study and were divided into three groups of 12 patients: a therapeutic exercise program (G1, mean age: 26.3±5.6 years), a therapeutic and aerobic exercise program (G2, mean age: 26.0±4.6 years), and an aerobic exercise program (G3, 25.8±2.94 years). Headache frequency and intensity were evaluated using a headache diary, and the adverse headache impact was evaluated using the Headache Impact Test (HIT-6). The intensity was reported using the numerical pain rating scale. These parameters were evaluated twice at baseline (A01/A02), at the end of the 8-week intervention period (A1), and 8–12 weeks after the end of the intervention (A2). Results At A1, none of the G2 patients reported having headaches, in G1, only two patients reported headaches, and in G3, ten patients reported headache. The headache intensity scores (0.3 [95% CI: -0.401, 1.068]), (0.0 [95% CI: -0.734, 0.734]) and HIT-6 (50.7 [95% CI: 38.008, 63.459]), (49.5 [95% CI: 36.808, 62.259]), significantly decreased in G1 and G2 at A1. At A2 headache intensity scores (0.5 [95% CI: -0.256, 1.256]), (0.0 [95% CI: -0.756, 0.756]) and HIT-6 (55.1 [95% CI: 42.998, 67.268]), (51.7 [95% CI: 39.532, 63.802]) in G1 and G2 haven’t change significantly. The effects obtained immediately after the completion of the intervention programs were maintained until the final follow-up in all groups. Conclusion The programs conducted by G1 (therapeutic exercises) and G2 (therapeutic and aerobic exercise) had significant results at A1 and A2.

Resumo Introdução: Os desvios posturais associados às mudanças de hábitos em adolescentes vêm aumentando nas últimas décadas. Investigar por meio de questionário de autopercepção permite entender o nível de consciência que o indivíduo tem dos hábitos posturais. Objetivo: Construir um questionário de avaliação da autopercepção dos hábitos posturais de jovens, validar, pré-testar, verificar a confiabilidade e a consistência interna do instrumento. Métodos: A validade de conteúdo foi analisada por 10 juízes. O estudo envolveu jovens (15 - 18 anos) de Florianópolis/Brasil. O questionário foi pré-testado, aplicado a 15 jovens que forneceram informações qualitativas sobre ele. A reprodutibilidade foi analisada através do teste-reteste com 40 alunos, em um intervalo de 1 semana, os dados foram analisados por meio do coeficiente de correlação intraclasse. A consistência interna foi analisada por meio do Alpha de Cronbach com 679 jovens. Adotou-se nível de significância de 5%. Resultados: Na validação de conteúdo o questionário apresentou um coeficiente total de 0.28, observou-se uma concordância de 72% entre os avaliadores. O questionário foi considerado adequado, de rápido e fácil preenchimento. Os coeficientes de correlação intraclasse (teste-reteste) indicaram valores de reprodutibilidade aceitáveis (R = 0.66; 0.74 e 0.59; p < 0,001), com baixa na dimensão carregando objetos (R = 0.32; p = 0.04). A consistência interna apresentou um valor de 0.80. Conclusão: O questionário de percepção corporal dos hábitos posturais de jovens é um instrumento válido, com boa repetibilidade, confiabilidade e seu uso pode ser recomendado para adolescentes com o mesmo perfil deste estudo.

Abstract Introduction: The postural deviations associated with the changes in the habits of young people have increased over the last decades. Investigating the subject by way of a self-perception questionnaire allows one to understand the level of awareness the individual has concerning his/her postural habits. Objective: Designing a self-perception evaluation questionnaire about the postural habits of young people and to validate, pre-test, verify the reliability and the internal consistency of this instrument. Methods: The validity of the content was determined by 10 judges. The study involved young people (15 - 18 years old) from Florianopolis/Brazil. The questionnaire was pre-tested, applied to 15 youthful who provided qualitative information about it. The reproducibility was analyzed by way of a test-retest with 40 students, in a one-week gap, and was analyzed by interclass correlation coefficient. The internal consistency was analyzed by Cronbach’s alpha with 679 students. A 5% significance level was adopted. Results: Concerning to the validation of content, the questionnaire presented a total coefficient of 0.28 and 72% concordance was observed amongst the reviewers. The interclass correlation coefficient (test-retest) indicated acceptable reproducibility values (R = 0.66, 0.74 and 0.59; p < 0.001), with a decrease in the object-carrying dimension (R = 0.32; p = 0.04). The questionnaire was considered suitable, quick and easy to fill in. The internal consistency presented a value of 0.80. Conclusion: The questionnaire on body awareness of postural habits in young people is a valid instrument with good repeatability and reliability, its use can be recommended with teenagers showing the same profile as those used in this study.
