The purposes of this study were to determine whether two bolus
transition durations (oral transit time and pharyngeal transit time) were
different during oropharyngeal swallowing in post-stroke patients who aspirated
and who did not aspirate and to examine those differences across varying bolus
viscosities. DESIGN: Means and standard deviations of oral transit time and
pharyngeal transit time were analyzed on 5 ml of thin and nectar thick liquids
and puree swallows from videofluoroscopic swallowing examinations of 30
post-stroke patients. Statistical comparisons were made by repeated measures
analysis of variance, with the within-subject variable being the three
consistencies and the between-subject variable being the two groups. Significance
level was set at P < 0.025. RESULTS: Oral transition of the bolus did not differ
between the two patient groups. Pharyngeal transition of the bolus differentiated
the patients who aspirated from the patients who did not aspirate. Both the oral
and pharyngeal transitions differed significantly for the puree compared with the
thin and nectar thick liquids. CONCLUSIONS: Patients who demonstrate prolonged
pharyngeal transit times may be at risk for aspiration.
