Mean (upper panel) and variability (lower panel) of relative phase between pelvis and thorax rotations as a function of group and Stroop condition. CONTROL = walking without Stroop test; BASE = baseline Stroop condition; INCO = incongruent Stroop condition; MOVE = movement related Stroop condition. Error bars represent standard errors. Asterisk indicates a significant (p < .05) difference between the two levels.
