ABSTRACT
TEMA: controle postural de escolares com respiração oral. OBJETIVO: comparar postura e equilíbrio corporal entre os grupos de escolares com e sem respiração oral considerando a variável gênero. MÉTODO: o estudo foi realizado em uma escola municipal da cidade de Santa Maria; foi aprovado pelo Comitê de Ética da Universidade Federal de Santa Maria. O grupo estudo (com respiração oral) e o grupo controle (sem respiração oral) foram selecionados, baseados na anamnese, na idade (entre 8 a 12 anos), na avaliação do sistema estomatognático e na avaliação auditiva. A amostra final ficou composta por 51 escolares no grupo estudo (20 gênero feminino e 31 gênero masculino) e 58 escolares no grupo controle (34 gênero feminino e 24 gênero masculino). Ambos os grupos foram submetidos à posturografia dinâmica (teste de organização sensorial -TOS - e análise sensorial) e à avaliação postural em vista lateral direita e esquerda. RESULTADO: no gênero feminino encontrou-se diferença estatisticamente significante nos valores obtidos no ângulo que analisa o alinhamento horizontal da cabeça, nos valores do TOS III e no valor médio de todos os TOS. No gênero masculino verificou-se diferença numericamente significante nos valores obtidos no ângulo do joelho, no ângulo do tornozelo, no TOS III, TOS IV e no valor médio de todos os TOS. CONCLUSÃO: escolares com respiração oral apresentam alterações posturais; no gênero feminino no posicionamento cefálico e no masculino em membros inferiores. O equilíbrio corporal dos escolares com respiração oral, em ambos os gêneros, mostrou estar mais prejudicada em relação aos escolares sem respiração oral, principalmente na presença de conflito sensorial.
BACKGROUND: postural control of mouth breathing school aged children. AIM: to compare the posture and body balance of school aged children groups, with and without oral breathing considering the variable gender. METHOD: the study was developed at a municipal school in the city of Santa Maria (Brazil) and received prior approval of the ethics committee of the University of Santa Maria. The study group (with oral breathing) and the control group (without oral breathing) were selected based on an anamnesis, age (between 8 and 12 years), assessment of the stomatognathic system and auditory evaluation. The final sample was composed by 51 children in the study group (20 female and 31 male) and 58 in the control group (34 female and 24 male). Both groups were submitted to a dynamic posturography (sensory organization test - SOT) and to a postural assessment in right and left lateral view. RESULTS: regarding the female gender, a statistically significant difference was observed for the angle that evaluates head horizontal alignment; for the SOT III value and for all SOT mean values. As for the male gender, a significant numerical difference was observed for the knee angle, for the ankle angle, for the SOT III value, for the SOT IV value and for all SOT mean values. CONCLUSION: school aged children with oral breathing present postural alterations; females present head positing alterations and males present alterations in the position of the inferior limbs. The body balance of school aged children with oral breathing, of both genders, demonstrated to be altered when compared to children without oral breathing, especially in the presence of sensorial conflict.

The final sample was composed by 51 children in the study group (20 female and 31 male) and 58 in the control group (34 female and 24 male). Both groups were submitted to a dynamic posturography (sensory organization test--SOT) and to a postural assessment in right and left lateral view. RESULTS: Regarding the female gender, a statistically significant difference was observed for the angle that evaluates head horizontal alignment; for the SOT III value and for all SOT mean values. As for the male gender, a significant numerical difference was observed for the knee angle, for the ankle angle, for the SOT III value, for the SOT IV value and for all SOT mean values.
