The earlier trial also found no difference in walking speed (effect size = 0.00 [−0.08, 0.08]) 9 , 11 but did report a highly significant increase ( P = .0001) in FAC score from a median of 1 (1-1) to 2 (1-2). 12 However, the earlier trial had a greater risk of potential bias than the one reported here for the following reasons: randomization was not to group but to the order of each individual using an AFO once the control walk (without AFO) had been made; observers were not masked to conditions because participants used the AFO during testing sessions; and an independent randomization service was not used.
