The study of the back muscles bioelectric activity in 216 children in the age between 10-15 years showed that the total paravertebral muscles bioelectrical activity on the convex side of the proximal curve and on the concave side of its distal part is higher compared with that on the opposite side. Analysis of H-reflex and M-responses in 302 patients in the age between 10-15 years created a normative database. This allows, in comparison with the total individual electrophysiological parameters, to determine patient's progression risk.
