The mechanisms of reorganization of motor systems at the poststroke patients after rehabilitation were studied using the method functional magnetic resonance imaging (fMRI). At patients after standard rehabilitation therapy, irrespective of localization of stroke, the increase in intensity of the basic activity zones in sensomotor areas and in the field of a hemisphere of a cerebellum as for paretic, so for a healthy hand was revealed. At patients after EMG biofeedback training of the precision grip the reorganization of functional motor system consists in more significant increase of intensity of activation of the basic zones only in lesioned hemisphere; expressiveness of these changes did not depend on localization of stroke. The degree of restoration of movements of hand after EMG biofeedback training was authentically above, than after a course of standard rehabilitation therapy. Thus, fMRI and the clinical analysis have shown that EMG biofeedback training of the precision grip have the goal-directed and effective influence upon processes of functional reorganization of motor systems.
