Abstract

Способ оценки функционального состояния центральной нервной системы человека на основе измерения времени ориентировочной зрительно-моторной реакции человека, включающий предъявление зрительного стимула, отличающийся тем, что человеку предъявляют зрительный стимул, например красный круг диаметром 20 мм, который визуально определяет его место появления и подводит курсор компьютерной мышки к его границам, измеряют время от момента появления стимула до подведения курсора к его границе, процедуру повторяют не менее 50 раз и рассчитывают величину уровня функционального состояния ЦНС (УФС) по формуле:где- среднее значение;Кв - коэффициент вариацииМо - середина разряда гистограммы, имеющего максимальную частоту (в мс, ширина разряда 20 мс.) [2, 3];Т- срединный интервал при А=50%;А- амплитуда моды в % - максимальная относительная частота гистограммы;ΔХ - вариационный размах=X-X;Ln - натуральный логарифм,и далее определяют по величине рассчитанного показателя уровень (слово добавлено) функционального состояния ЦНС, причем при значении УФСбольше 24,57 уровень (слово добавлено) функционального состояния будет оцениваться как оптимальный, при УФСот 24,56 до 18,53 - как сниженный, и при УФСменьше 18,52 - как существенно сниженный.A method for assessing the functional state of the central nervous system of a person based on measuring the time of an approximate visual motor reaction of a person, including presenting a visual stimulus, characterized in that a visual stimulus is presented to a person, for example, a red circle with a diameter of 20 mm, which visually determines its place of occurrence and brings the computer cursor mice to its borders, measure the time from the moment the stimulus appears to bring the cursor to its border, repeat the procedure at least 50 times and calculate the value of the level of the functional state of the central nervous system (UFS) according to the formula: where is the average value; Kv is the coefficient of variation Mo is the middle of the discharge of the histogram having the maximum frequency (in ms, the width of the discharge is 20 ms.) [2, 3]; T is the middle interval at A = 50%; A- mode amplitude in% - maximum relative histogram frequency; ΔХ - variational range = XX; Ln - natural logarithm, and then the level (word added) of the central nervous system functional state is determined by the value of the calculated indicator, and with UV value more than 24, 57 level (word added) functional conditions will be assessed as optimal, with a UVF of 24.56 to 18.53 - as reduced, and with a UVF of less than 18.52 - as significantly reduced.

Claims

A method for assessing the functional state of the central nervous system of a person based on measuring the time of an approximate visual motor reaction of a person, including presenting a visual stimulus, characterized in that a visual stimulus is presented to a person, for example, a red circle with a diameter of 20 mm, which visually determines its place of occurrence and brings the computer cursor mice to its borders, measure the time from the moment the stimulus appears to the cursor to its border, repeat the procedure at least 50 times and calculate mask level functional state of the CNS _{(central nervous system} UFS) by the formula:

Where

- average value;

Kv - coefficient of variation

Mo is the middle of the discharge of the histogram having the maximum frequency (in ms, the width of the discharge is 20 ms.) [2, 3];

T _0.5 - median interval at A _Mo = 50%;

And _Mo is the amplitude of the mode in% - the maximum relative frequency of the histogram;

ΔХ - variational range = X _MAX -X _MIN ;

Ln is the natural logarithm,

and then the level (word added) of the central nervous system functional state is determined by the value of the calculated indicator, and if the _{central nervous system has a} UFS value of more than 24.57, the functional state level (word added) will be assessed as optimal, while the _{central nervous system has a} UFS of 24.56 to 18.53 - as reduced, and with UFS, the _{central nervous system is} less than 18.52 - as significantly reduced.
