Changes in relative stance times and stride time during split-belt walking (A and D) and correlations with stance time symmetry during the early phase of the post condition (B, C, and E). A: relative stance times of the fast and the slow leg changed in opposite directions during split-belt walking. Aftereffects (early post) were significantly different from baseline, and for the slow leg this aftereffect was larger in the patient group. B and C: relative stances times of both legs were correlated with stance time symmetry during the early phase of the post condition. D: stride time was increased during late split and reduced during early post; this reduction was most pronounced for the healthy controls. E: stride time and stance time symmetry were correlated during the early phase of the post condition. Data for cerebellar patients are presented in gray and for healthy controls in black; data for the fast leg are presented with dashed lines and for the slow leg with solid lines. Error bars represent SE. Asterisks indicate values significantly different from baseline. Pound signs indicate values significantly different between groups.
