Fig. 8. Temporal coordination between contralateral (A) and ipsilateral (B) legs.
Time delays of lift-off of two receiver legs relative to touch-down of the
perturbed sender leg. (A) Delay between AEP of the perturbed front leg and PEP
of its contralateral neighbour. In unperturbed reference steps (ref., filled
symbols), the delay was significantly shorter if the sender leg was an outer
leg (grey, right; Mann-Whitney U-test). After perturbation (pert.,
open symbols), delays significantly decreased if the sender leg was in the
straight walking (black, middle) or inner leg context (grey, left; Wilcoxon
test). (B) Delay between AEP of the perturbed front leg and PEP of its
ipsilateral middle leg. In unperturbed steps, delays significantly differed
between outer and inner leg contexts. In the perturbed steps, the middle leg
lifts off earlier in straight walking and in outer legs. Boxes, 25-75% of the
data; notch, 95% confidence interval of the median (centre of notch);
whiskers, 5% and 95% percentiles. Squares, mean. Significance levels:
***P<0.001; **P<0.01;
*P<0.05.
