[Electrophysiological evaluation of the age-related characteristics of the central nervous system in children with spastic cerebral palsy].

As a result of the conducted studies, the authors were able to demonstrate that in children from 4-9 years with cerebral spastic paralysis the potentiated tonic reactions are preserved (the reflex of distention from the gastrocnemius muscle, cervico-tonical reflex to the extremities and reaction of support). The frequency and regularity of alpha-rhythm on the EEG of these children differ significantly from similar ones of normal children of the same age. As the children grow older, the frequency of exaltated tonic reactions decrease and at the same time the frequency and regularity of alpha-rhythms increases, however the differences compared to age norms are preserved. The authors are of the opinion that in older children with infantile cerebral paralysis, despite the retardation of the morpho-functional development of the higher areas of the brain, the degree of cortical maturity is sufficient to inhibit an increased activity of the stem centres regulating the muscular tone.
