Effects of muscle respiratory exercise in the biomechanics of swallowing of normal individuals/Efeitos do exercicio muscular respiratorio na biomecanica da degluticao de individuos normais

Purpose: to analyze the effects of the respiratory exercise in the biomechanics of swallowing in normal subjects. Methods: the muscle respiratory's exercise in normal subjects was administered for seven consecutive days by the incentive spirometer flow (three sets of ten repetitions for inspiration and expiration).The biomechanics of swallowing was evaluated by videofluoroscopy through temporal variables (pharyngeal transition time) and visuoperceptual (number of swallows, waste in the pyriform sinuses and valleculae, penetration/aspiration). For statistical analysis was used the Wilcoxon test, Equality of Two Proportions and Kappa. Results: were evaluated 16 young women with a mean age of 21,2 [+ or -] 3,4 years. In visuoperceptual variables was observed almost perfect agreement between evaluators (p
