Difference of means, variability, and extremes of spatiotemporal gait parameters during perturbed walking conditions relative to normal walking.

<p>Difference of means of (A) stride length, (B) step width, and (C) cadence. Difference of variability of (D) stride length, (E) step width, and (F) cadence. Difference of 10th percentile of (G) stride length, (H) step width, and (I) cadence. Difference of 90th percentile of (J) stride length, (K) step width, and (L) cadence. <i>d</i> indicates Cohen’s <i>d</i> statistic effect size. Error bars indicate confidence intervals. (*) indicates statistically significant differences from Normal walking.
