M\u00c9TODOS: Estudo anal\u00edtico transversal com um grupo controle no qual foram inclu\u00eddas crian\u00e7as de 8 a 12 anos com diagn\u00f3stico cl\u00ednico otorrinolaringol\u00f3gico de RB, recrutadas do Ambulat\u00f3rio do Respirador Bucal do Hospital de Cl\u00ednicas da Universidade Estadual de Campinas, Campinas (SP), entre outubro de 2010 e janeiro de 2011. Os crit\u00e9rios de exclus\u00e3o foram obesidade, asma, doen\u00e7as respirat\u00f3rias cr\u00f4nicas, cardiopatias e dist\u00farbios neurol\u00f3gicos ou ortop\u00e9dicos. Todos os participantes foram submetidos a avalia\u00e7\u00e3o postural, teste de caminhada de seis minutos (TC6) e determina\u00e7\u00e3o de PIm\u00e1x e PEm\u00e1x. RESULTADOS: Das 92 crian\u00e7as do estudo, 30 tinham RB e 62 tinham RN. No grupo RB, n\u00e3o houve diferen\u00e7as nas m\u00e9dias de PIm\u00e1x, PEm\u00e1x e dist\u00e2ncia percorrida pelo TC6 (DTC6) entre o grupo com AC classificada como grave ou moderada e aquele com AC normal (p = 0,622; p = 0,957; e p = 0,079, respectivamente). No grupo RN, as m\u00e9dias de PIm\u00e1x e PEm\u00e1x foram maiores no grupo com AC moderada do que naquele com AC normal (p = 0,003 e p = 0,004, respectivamente). Os valores de PIm\u00e1x, PEm\u00e1x e DTC6 foram menores no grupo RB do que no grupo RN. A presen\u00e7a de AC moderada determinou maiores valores de PIm\u00e1x e PEm\u00e1x. CONCLUS\u00d5ES: A RB afetou negativamente a biomec\u00e2nica respirat\u00f3ria e a capacidade de exerc\u00edcio. A presen\u00e7a de AC moderada atuou como um mecanismo de compensa\u00e7\u00e3o para uma melhor fun\u00e7\u00e3o da musculatura respirat\u00f3ria.<\/jats:p>","DOI":"10.1590\/s1806-37132011000400009","type":"journal-article","created":{"date-parts":[[2011,8,29]],"date-time":"2011-08-29T17:32:06Z","timestamp":1314639126000},"page":"471-479","source":"Crossref","is-referenced-by-count":50,"title":["Respira\u00e7\u00e3o
