Fig. 2

Spatiotemporal parameters (Mean ± SD) of recovery stepping responses during single- and dual-task perturbed walking. Figs. A–E: [A] Margins of Stability, [B] Reaction Time, [C] Step Length, [D] Swing Time, [E] Step Time. Linear regression coefficients are noted, as well as results of the Wilcoxon signed rank test; * p = 0.052, **p = 0.041., ***p = 0.026.
