Fig. 6
ΔCOP and ΔGRF of outward-directed perturbed walking. Group mean values and standard deviations are shown for all three groups. P-values indicate statistically significant effect of group factor and statistically significant differences between groups in Bonferroni post-hoc paired comparisons were found. Note that positive values of ΔCOPML indicate change in the direction of perturbation direction. Also note that positive values of ΔGRFML indicate change in the direction opposite to perturbation direction
