Abbreviations: SD=Standard Deviation, SIS=Stroke Impact Scale, ABC=Activity Balance Confidence, 6MWT=6-minute walk test, m=meters, BBS=Berg Balance Scale, SSWS=Self-Selected Walking Speed, m/s=meters/second, FWS=Fast Walking Speed.

^†indicates medians due to skewed data. P-values determined by t-test for age, 6MWT, SSWS, FWS; chi-squared test for gender and side affected; Mann-Whitney U test for Stroke Chronicity, SIS Recovery %, BBS.
