Integrated assessment of back muscles bioelectrical activity and H-reflex research in AIS.

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.

Bioelectric activity in the suprachiasmatic nucleus-pineal gland system in children with adolescent idiopathic scoliosis.

The purpose of this work is to identify a role of the pineal gland/suprachiasmatic nucleus system in adolescent idiopathic scoliosis (AIS) aetiology and pathogenesis. To analyze electroencephalograms of 292 children with AIS and in 46 healthy subjects, a processing method was used to assess three-dimensional coordinates of electric equivalent dipole sources (EEDSs) within the brain. Amounts of EEDSs in the pineal gland and suprachiasmatic nucleus (SCN) area were assessed in different age groups and during the progress of orthopaedic pathology.
