Ontogenesis of the nervous, muscular and cardiovascular systems in patients with I-II degree scoliosis. Report I. Dynamics of EEG values in patients at the age of 6-18 years with I-II degree scoliosis

The problem of development of the complex nervous system providing a controlling function in ontogenesis in patients with I-II degree scoliosis is of current interest, and it is little worked out. The aim of the present work was to study ontogenesis of specific and non-specific regulatory systems in patients with I-II degree scoliosis on the basis of the probabilistic analysis of the brain bioelectrical background activity. The studies were performed in 104 patients at the age of 7-18 years with I-II degree scoliosis. The functional condition of cerebral hemisphere cortex was evaluated by the data of frontoparietal lead EEG. The reliably high values of ƒ- and ƒ-rhythm activity were obtained in patients of the age-related group of 6-10 years, as well as the low values of ƒ2- and ƒ-activity, in comparison with other age-related groups thereby evidencing the immaturity of both the frontothalamic and non-specific regulatory systems. Complete maturation of the brain regulatory systems in patients with I-II degree scoliosis takes place by the age of 18 years.
