ABSTRACT:
Purpose:
to analyze the effects of the respiratory exercise in the biomechanics of swallowing in normal subjects.
Methods:
the muscle respiratory exercise in normal subjects was performed 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 video fluoroscopy through temporal variables (pharyngeal transition time) and visual-perceptual (number of swallows, waste in the pyriform sinuses and vallecula, penetration/aspiration). For statistical analysis, the Wilcoxon test, Equality of Two Proportions and Kappa were used.
Results:
16 young women with a mean age of 21,2±3,4 years were evaluated. In visual-perceptual variables it was observed almost perfect agreement between evaluators (p<0,001) and in temporal variable (p=1,00). After the training period there was a significant reduction in the pharyngeal transition time (p=0,02).
Conclusion:
the use of incentive spirometer flow significantly influenced the biomechanics of swallowing, especially in reducing the pharyngeal transition time.
