Ground reaction forces. (A,B) Maximal propulsive (anterior) GRFs and impulses were not affected by HD-tDCS. The propulsive GRFs and impulses were greater in the non-paretic side compared to the paretic side, which is commonly seen in this population. (C,D) Maximal braking (posterior) GRFs and the posterior impulses were not different between the legs. However, there was a significant stimulation type × time point interaction revealing an increase (more negative) in peak braking forces after cathodal stimulation (C). P < 0.05.
