Differences in ERD/ERS (active–passive) from the estimated clusters during a stride from a, b all subjects and subjects with brain lesions on c, d the left and e, f right side of their brain. For each group, the left and right columns indicate the slow and fast walking trials, respectively. The vertical lines in the ERSP plots indicate gait phase indices (RHO, LTO, LHS, and RTO). Statistically nonsignificant differences (p > 0.05) were masked with zero, as shown in light green
