Aim of the work is the research of the functional condition of the central nervous system of schoolchildren with different deafness levels.
47 schoolchildren with different deafness levels aged 8 -12 years, studying in special (corrective) educational institutions "Boarding schools I-II type" of Krasnodar region, were examined.
To characterize functional condition of CNS in children with auditory deprivation tapping-test was used by filling in maximum dots on a sheet of a paper with 6 squares upon visual command. After calculating dots in squares the lability of nervous processes was estimated (T-10- dot quantity during first 10 sec, T-30 - 30 sec, T-mark - tapping test estimation in marks), speed endurance (Т-60 - 60 sec), results of nervous processes strength and fatigability (Q - coefficient of fatigability) (V.A. Romanenko, 2005).
As a result of the undertaken research it was determined that hearing-impaired schoolchildren in comparison to a group of almost healthy peers had lower (p<0,05) tapping-test results (Т-10, Т-30, Т-mark). The same data were obtained while analyzing speed endurance results (p<0,001). In its turn fatigability coefficient in children with auditory deprivation was higher than in healthy peers (р<0,05).
Thus, the undertaken research detected that children with different deafness levels have low endurance level and sped- strength characters of complex-coordination CNS activity.
