Data are presented as the median (Interquartile range) (The Shapiro–Wilk test was used to determine the values are not normally distributed). IH, ipsilateral hemisphere relatively to the stimulating side; CH, contralateral hemisphere relatively to the stimulating side. Change values were calculated by subtracting the baseline data from the post-test data. ap < 0.05 as compared with M1 group; sp < 0.05 as compared with Sham group.
