Study Description
Brief Summary:
The purpose of this study is to characterize the posture and respiratory function of mouth-breathing children.

Condition or disease
Mouth Breathing

Detailed Description:
Mouth-breathing children presents changes in stomatognathic system, which results in head projection, tension augment in scapular belt muscles and postural adaptations. Although thoracic shape and posture can influence ventilatory dynamics, we didn't find studies addressing pulmonary function of mouth-breathing children. This was a transversal study, designed to analyze the posture of mouth-breathing children, and verify the existence of correlation between posture and pulmonary volumes.

Study Population

Mouth-breathing children were referred by Pediatrics Service (Federal University of Rio de Janeiro) and by School of Dentistry (Federal University of Rio de Janeiro), after the diagnosis of mouth breathing was confirmed.

Nasal breathing children were recruited from Tia Ciata Municipal School (Praça Onze-Rio de Janeiro, Brazil).

Criteria

Inclusion Criteria:

  • Nasal breathing (normal subjects group) or mouth breathing (mouth-breathing group), and the age between eight (08) and twelve (12) for both groups.

Exclusion Criteria:

  • Prior physiotherapeutic treatment or in process, presence of diagnostic or report on acute or chronic pulmonary disease, neurofunctional or cognitive impairment and alteration of the osteomuscular system.
