  1. Time effect was assessed by a rank Wilcoxon test for single sample (null hypothesis: median = 0). Significance level p ≤ 0.01**, p ≤ 0.05*. 6MWT: 6-min walk distance, 4SC: 4-stair climb; RFF: rise from floor; 10MW: 10-m walk test; SV50C: 50th centile stride velocity; SV95C: 95th centile stride velocity; SL50C: 50th centile stride length; SL95C: 95th centile stride length
