METHOD FOR DETERMINATION OF LEVEL OF MENTAL FATIGUE Russian patent published in 2010 - IPC A61B3/00 A61B5/16 

FIELD: medicine.

SUBSTANCE: invention refers to medicine and medical equipment. Prior to and during mental work, paired light pulse train of duration 200 ms separated by pulse separation 70 ms and repeated every 1 s of regular time interval is presented to a person being tested. The successive approximation method is used to determine duration of threshold pulse separation whereat two pulses in a pair are fused in one. The level of mental fatigue is calculated by formula: LMF_i=(TPS_i-TPS₀)100%/TPS_i; i=1, 2,… n, where LMF_i is the level of mental fatigue in i-the measurement; TPS_i is duration of the threshold pulse separation in i-the measurement; TPS₀ is duration of the threshold pulse separation prior to the beginning of mental work; n is a number of measurements of the threshold pulse separation during mental work.

EFFECT: method extends the range of products for determination of the level of mental fatigue.
