Using computer stabilography, vertical posture has been studied in 3 groups of children and adolescences with traumatic lesion of the spinal cord after surgery of congenital myelocele (n=10) and myelodysplasia (n=10) and in 124 healthy controls. Also, an extent of segmental lesions was investigated by electroneuromyography of lower extremities muscles. Patients with pronounced segmental lesion had small-amplitude, -velocity and -frequency variations of body center of gravity (BCG) during standing with visual control. After excluding visual control of vertical posture, there was a significant decrease of vertical stability that suggests a relevant role of visual analyzer in the control of vertical posture. In patients with minor segmental lesion, BCG variations of small amplitude, velocity and frequency were observed. Exclusion of visual control did not result in significant reduction of vertical stability. it is concluded that stabilographic survey is an objective method for diagnosis of an extent of segmental lesion of the spinal cord.
