Table 2.
A comparison of findings in the VFSS and clinical oral intake conditions within and between hemispheric and brainstem groups.

Within-group and between-group comparisons of FDS, 8-point PAS, and FOIS were performed by the Wilcoxon signed-rank test and Mann-Whitney test. VFSS, videofluoroscopic swallow study; FDS, functional dysphagia scale; PAS, penetration-aspiration scale; FOIS, functional oral intake scale; IQR, interquartile range. p: comparison between before and after treatment in each group; p1, comparison between two groups before treatment; p2, comparison between two groups after treatment.
