6MWT, 6-minute walk test; BI, Barthel’s index; CRT, conventional rehabilitation training; DTW, dual-task walking test; ELLT, enhanced lower limb training; FAC, functional ambulatory classification; RAGT, robot-assisted gait training; SS-QOL, stroke-specific quality of life scale; T0, evaluation at baseline; T1, evaluation after 4 weeks of training; TUG, timed up and go.

p value is Bonferroni-corrected for pairwise comparisons of T1-T0.
