USING THE HEART RATE VARIABILITY FOR ASSESSMENT OF THE ADAPTIVE POSSIBILITIES OF CHILDREN WITH CEREBRAL PALSY
The state of the autonomic nervous system (ANS) reflects the processes of pathogenesis and adaptation of the body in the presence of somatic diseases, including infantile cerebral palsy (ICP). Methods and organization of research. We have studied the functional features of ANS of children with ICP (50 people aged 10 to 15 both males and females) according to the indicators of variability of cardiac rhythm. Data of variation cardiointervalography of surveyed people was analyzed in comparison with indicators of healthy pool of children of the same age and gender groups. Registration of cardiointervalograms was carried out at rest, in a sitting position at the first 15 seconds after a dozed physical exercise (20 squats in 30 sec.). Research results and discussion. Children with ICP in all surveyed groups had lower values of variation span (ΔХ), increased values of mode amplitude (AMo), index of the autonomic nervous balance (ANB) (to a greater degree for girls aged 10-11 and boys aged 14-15). At rest, the values of the stress index (SI) of the regulatory systems of children with ICP were higher than those of healthy children by 30-96%. Girls with ICP aged 10-11 and boys aged 14-15 had significantly lower ΔХ indicators, higher AMo, SI, ANB, parameters of adequacy of regulatory processes compared to the same indicators in other age groups. Children with ICP responded to dozed physical exercise by increasing ΔХ indicators and decreasing mode, AMo, SI (except girls aged 12-13), ANB parameters. Conclusion. The paper reveals the necessity of considering individual peculiarities of children with ICP for optimal releasing of adaptive potential of their bodies.
