Research Abstract	We found that simultaneous contraction and relaxation of muscles in ipsilateral hand and foot influenced with each other at behavioral level. In addition, it was suggested that neither contraction nor relaxation of foot muscle influenced excitability of corticospinal pathway of hand muscles.
