Figure 2.

Median and 95% confidence intervals (with individual data points) of the anteroposterior margins of stability during the first, second and ninth perturbations (Pert1_R, Pert2_L, and Pert9_L, respectively) including unperturbed walking prior to each perturbation (Base), the final step prior to each perturbation (Pre) and the first eight recovery steps following the perturbations (Post1–8) for Falls and No-Falls groups. Blue * and Red *: significant difference to Base for the No Falls and Falls groups, respectively (P < 0.05; adjusted using Dunnett's multiple comparisons test). ^#Significant difference between the No Falls and Falls groups (P < 0.05; adjusted using Sidak's multiple comparisons test).
