RESUMO
The Mouth Breathing Syndrome (MBS) has as main causes the craniofacial malformations, nasal or pharyngeal obstruction and, deleterious habits. The mouth breathing produces compensatory postural adaptation, especially on the head posture. Therefore, an interdisciplinary approach for the MBS has been recommended, not only considering the dentition, facial skeleton and head postures, but the whole body posture. Orthodontic, surgical, clinical treatments and speech therapy has been utilized in the MBS, however they do not addressed directly the postural and ventilatory problems resulted from nasal obstruction. Physical therapy, in these cases, seeks to reestablish the postural alignment and muscular balance, favoring the diaphragmatic muscular mechanics and the ventilatory capacity as well. This study proposed to evaluate the efficacy of aphysical therapy intervention program on the cervical muscles and body posture in mouth breathing children. The program of Physical therapy consisted by muscular stretching and strengthening exercises on the Swiss ball, along with naso-diaphragmatic re-education, during a three-month period. The study was carried out with 19 mouth breathing children, mean age of 10.6 years, with nasal obstruction diagnosis confirmed by endoscopic exams. To evaluate the efficacy of this intervention, electromyographic recordings and computerized photographic analysis were carried out before and after the physiotherapeutic intervention. The EMG signals were acquired from the sternocleidomastoid, sub-occipitals and upper trapezius muscles in quiet position, nasal inspiration, postural alignment and isometric contraction. The computerized photographic analysis enabled the measurement of multiple angles in order to quantify the results of this intervention on the body posture. The results showed significant reduction in the EMG activity on the assessed muscles after physiotherapy and, the computerized photographic analysis also indicates the treatment efficacy on body posture, particularly in the correction of forward head posture and abducted scapula. The objective methods adopted to verify the efficacy of the physical therapy intervention seemed to be safe and reliable, provided they are utilized with proper care and adequate instrumentation, evidencing that this intervention seemed to be effective on the improvements of the muscular balance and the postural pattern in mouth breathing children
