FIELD: medicine.

SUBSTANCE: invention relates to medical equipment and is intended for determining the asymmetry of components of the cognitive-motor function of a human operator. Disclosed is a method in which a person being tested is presented with a controlled object (CO) of a given size and shape on the monitor screen of the hardware-software complex (HSC) for test movement. Movement of CO on the field of the monitor is carried out using a joystick or a computer mouse or using touch screens. Novelty is that the CO interleaving is performed on the image of a labyrinth of a given size and shape, which has a given number of inputs and outputs and a given number of equal and/or unequal length transitions to opposite outputs. Person being tested identifies and assesses the complexity of the path to the proposed exit from the labyrinth and transfers the CO from the presented “Start” base to the “Finish” base. Size of the CO and/or the size and complexity of the labyrinth configuration is used to form the level of cognitive-motor load in each test. Feature of the method is that in each case of the CO moving from left to right and from right to left and/or from bottom to top and from top to bottom, mirror images of the labyrinth are presented to him/her in opposite directions. Characteristics of the CO and labyrinths are selected from the HSC library and are set by the researcher taking into account the preparedness of the person being tested. At moments of collision of CO with labyrinth walls the error of the person being tested is fixed, sound and/or light signal is supplied or not. Test is repeated for a given number of times. Repetitions are separated by breaks of preset duration. Time of successful CO passes from “Start” base to “Finish” base is fixed by HSC, their average value is calculated. To determine and assess the level of asymmetry of the cognitive-motor function of the person being tested, the arithmetic mean values of the CO movement speed are compared when passing: from left to right and from right to left and/or from bottom to top and from top to bottom. Level of cognitive-motor abilities of the person being tested is determined from the maximum error-free speed of actions of the person being tested: determining the optimal CO route and the accuracy of test performance under various variants of cognitive-motor load. Difference in arithmetic mean values of the CO displacement velocity in opposite directions is used to determine the level of asymmetry of the components of the cognitive-motor function of the person being tested. This method with the disclosed technical resources has new properties, which determine obtaining the disclosed technical result.

EFFECT: invention provides higher efficiency of testing a human operator.
