METHOD FOR ASSESSMENT OF TIME FOR TRAINING ON HOW TO ASSESS TIME OF INERTIA OF HUMAN VISUAL SYSTEM Russian patent published in 2010 - IPC A61B3/02 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and is intended to determine time for training on how to assess time of inertia of human visual system. The person being tested is exposed to pairs of light pulses, reference one with duration of 80 ms, and one adjustable in duration, repeating in a time interval of 1 s, duration-adjustable pulse is delayed or terminated earlier relative to time of the reference pulse initiation. At the first stage of measurements, time of delay or early termination of duration-adjustable pulse relative to the reference one is increased discretely with pitch of 5 ms, until the tested person determines the moment of subjective feeling that light pulses start or end in a staggered manner. At the second stage of measurements, time of delay or early termination of duration-adjustable pulse relative to the reference one is reduced discretely with pitch of 3 ms, until the tested person determines the moment of subjective feeling that light pulses start or end simultaneously. At the third stage of measurements, time of delay or early termination is increased discretely with pitch of 1 ms, until the tested person determines the moment of subjective feeling that light pulses end in a staggered manner. Time of visual system inertia is accepted as equal to time of delay or time of early termination of duration-adjustable light pulse relative to the reference one, determined at the third stage, and is marked by point in coordinates of "inertia time - measurement number". Described procedure is repeated more than once. Curve of time inertia values dependence on measurement number is built until quasistationary mode is obtained, as transition process is terminated. Time of training is determined by number of measurements performed during transition process.

EFFECT: method makes it possible to take into account individual character of stabilisation of measured values of inertia time of human visual system.
