 Furthermore, recent studies have demonstrated that the unaffected hemisphere exerts abnormally high inhibitory influence over the affected hemisphere. This abnormality might adversely influence motor recovery. Therefore a further purpose of the study is to apply tDCS to the unaffected hemisphere tDCS unaffected to test the hypothesis that down regulation of activity in the intact hemisphere, in combination with PNS of the affected hemisphere, will elicit more prominent improvement in functional relevant tasks than either intervention alone.
