^a(H&Y): the range of scores is one to five, indicating, respectively, unilateral involvement usually with minimal or no functional disability, and confinement to bed or wheelchair unless aided [12].
^b(FOIS): the range of scores is one to seven, indicating nothing by mouth to total oral diet with no restrictions [13].
