Values are Median (Quartiles range). CON, conventional; NIHSS, National Institutes of Health Stroke Scale; LE-FMA, Fugl-Meyer Assessment of lower extremity; FAC, Functional Ambulation Category; 6MD, 6-minute walk distance; CWS, comfortable walking speed; BI, Barthel Index; FIM, Functional Independence Measure. Differences within groups was used Wilcoxon signed-rank test. Differences between groups was used Mann–Whitney U test.
