Purpose
To correlate the total oral transit time (TOTT) with initiation of pharyngeal response (IPR) and pharyngeal transit time (PTT) in stroke.
Methods
The study included 61 swallowing videofluoroscopy exams of individuals after hemispheric ischemic stroke. Of these, 28 were male and 33 female, with ages ranging from 40 to 101 years (mean 65 years). For analysis of the results, individuals were divided into two groups. Group 1 (G1) consisted of 17 individuals with TOTT up to 2000 ms, as normality, and Group 2 (G2) consisted of 44 individuals with TOTT greater than 2000 ms. Temporal measurement of oropharyngeal swallowing was performed. Each individual was observed during the swallowing of a 5 mL spoonful of food in puree consistency. The Spearman´s rank correlation coefficient test was applied.
Results
There was no correlation between G1 and IPR and PTT. There was weak correlation between G2 and the studied parameters.
Conclusion
The increase of TOTT in the stroke individual has weak correlation with increased time in the pharyngeal phase.
