In patient 2, for the affected hemispheres and in patients 1, 4 and 5 for both hemispheres an uncorr. p< .001 was used because with the significance level of uncorr. p< .05 the activated clusters in the ipsilesional hemisphere was too large to distinct the anterior and posterior bank of precentral gyrus. For EMG the EMG-ratio is given. *= uncorr. p< .001.
