The IPA were built on the basis of motor asymmetry of hands, asymmetry of visual half-fields, and asymmetry of muscle extension tone in vertical position in Romberg test at computer stabilograph. The visual stimulation was realized by unilateral tachistoscopic administration of a verbal stimulus in the visual half-field on the side of worst detection of the master stimulus during the procedure of initial IPA construction. The IPA were different in children, adults, and patients. Even single visual stimulation changed the initial IPA (not only its visual but motor and stability-related components). A correlation was shown between the individual features of realization of the vertical position, initial IPA, age of the subjects, and presence/absence of the cerebral palsy. The visual stimulation led to a decrease in initially low stability and, on the contrary, an increase in initially high stability both in healthy subjects and patients with cerebral palsy, regardless of their handedness. Increase in stability of the vertical posture was accompanied by a decrease in the role of the visual analyzer, and, on the contrary, decrease in stability was associated with an increase in the role of the visual analyzer in stability control. It is necessary to take into account the dissimilar action of sensory stimulation on the IPA and stability of the vertical posture in assessment of the effects of sensory stimulation on healthy persons and patients with CNS lesions, in particular, with cerebral palsy, in the course of development of new ways of treatment.
