Statistical analyses
The data did not follow a normal distribution (Shapiro–Wilk test and visual inspection). The Friedman test was used to compare the effects of the conditions (hAFO, plsAFO and noAFO) on the 6MWT, TUG test and the 13 variables from the 3D gait analysis. When significant differences were found, the Wilcoxon test was used post-hoc to determine which conditions differed. The Wilcoxon test was also used to compare the hAFO and plsAFO conditions on the two QUEST subscales (device and services) and the total QUEST score. To control the false discovery rate, a Bonferroni procedure was performed to adjust the alpha risk threshold (P-value) at 0.0031 (0.05/16) for the 13 Friedman tests and 3 Wilcoxon tests (n = 3) and at 0.017 for the 3 post-hoc Wilcoxon tests (n = 3) for each significant Friedman test. Effect sizes were also calculated using Hedges’ g adapted for dependent data [
