Objective: This study examined the correlation between dysarthria and aspiration to determine if dysarthria canpredict aspiration in stroke patients.
Methods: The medical records of 176 patients with first stroke, who underwent a videofluoroscopic swallowing study(VFSS) and Urimal test of articulation and phonology (U-TAP) at the same time between January 2012 and December2015 in the authors’ hospital, were reviewed retrospectively. The correlation between the penetration aspirationscale (PAS) score and U-TAP score was analyzed in all patients. The mean PAS score and frequency of each PAS scorein the dysarthria group and non-dysarthria group were compared. In addition, the aspiration was analyzed based onthe severity of dysarthria in the dysphagia group. All statistical analyses were performed using SPSS software.
Results: The correlation between the PAS score and U-TAP score was not statistically significant in all the subjects.
The mean PAS score was 3.46±5.52 and 3.07±5.49 in the dysphagia and non-dysphagia group, respectively. The meanPAS score of the dysphagia group was higher than that of the non-dysphagia group. On the other hand, it was notstatistically significant. In addition, there was no significant difference in the frequency of the PAS scores betweenthe two groups. The aspiration was compared with the severity of dysarthria according to the U-TAP score; therewas no statistically significant difference.
Conclusion: No correlation was observed between dysarthria and aspiration in stroke patients. In addition, there wasno difference in the frequency of aspiration with or without dysarthria. According to the results of this study, aspirationcannot be predicted by dysarthria in stroke patients. Therefore, each diagnostic test and assessment shouldbe performed for each symptom.
