CRT, conventional rehabilitation training; ELLT, enhanced lower limb training; RAGT, robot-assisted gait training; ROM, range of motion; SPSR, swing phase symmetry ratio; T0, evaluation at baseline; T1, evaluation after 4 weeks of training.

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