Fig. 3From: Improved cortical activity and reduced gait asymmetry during poststroke self-paced walking rehabilitationa The topographical maps of the estimated clusters and the ERSP from each cluster for b the passive and c active walking trials at the slow speed from all subjects. The ERSP for d the passive and active walking trials at the fast speed. The vertical lines in the ERSP plots indicate gait phase indices (RHO, LTO, LHS, and RTO)Back to article page
