Mu band event-related desynchronization (ERD) areas (%) of the control and stroke group (n = 16 each) with error bars (standard deviations) for the three test conditions (NoMVF, BMVF, and delayed RMVF) for the IH (C3), SMA (Cz), and CH (C4) brain areas, respectively. The ERD areas (%) are shown as P0: white, P1: gray, and P2: black; a time-course change in cortical activation can be observed. *,ERD areas (%) of this test condition are significantly higher than the areas of the previous test condition for the same brain area.
