Objective: To evaluate the effects of the use of respiratory biofeedback (RB) associated with quiet breathing on the thoracic perimetry, pulmonary function, force of the respiratory muscles and the following habits of functional mouth breathing (FMB): vigil of open mouth, sleeps of open mouth, dribbles in the pillow, difficult wakening, snore and restless sleep. Methods: It had been evaluated 20 FMB children, which had been submitted to 15 sessions of RB, through biofeedback pletsmovent (MICROHARD® V1.0), which provides the biofeedback of the thoraco-abdominal movements. Thoracic perimetry, spirometry and measures of the maximum static respiratory pressures were determined before and after the therapy. Subjects answered by the responsible ware used to evaluate the habits of FMB. paired Student’s t test and nonparametric tests had been used for analysis of the data. Results: The use of the RB associated with quiet breathing didn’t produce significant alterations in the thoracic perimetry and in the values of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak of expiratory flow (PEF), Tiffeneau indice (TI) and in the maximal expiratory pressure (PEmax). However, the maximal inspiratory pressure (PImax) presented significant statistic difference (-53.6 ± 2.9 cmH2O vs. -65.0 ± 6.0 cmH2O; p < 0.05) and happened significant changes in the evaluated habits. Conclusion: The results allow to conclude that the RB associated with quiet breathing improves the force of the inspiratory muscles and habits in FMB, therefore, it can be used as form of therapy in these individuals.
