Efficiency of Hardware and Software Systems in the Assessment of Psychophysiological State of Persons in Extreme Conditions Professions

Abstract

Aim. To determine the effectiveness of hardware and software complexes in assessing the psychophysiological state of persons in extreme conditions professions. Material and methods. The post-hoc comparative analysis of sensitivity, specificity, and overall accuracy of five hardware and software complexes was performed involving 459 patients of different medical and preventive care institutions that received the rehabilitation medical care. The simulation of altered reactivity in 6 athletes of cyclic kinds of sport was carried out within a daily experiment (5 men, mean age 21.1±0.7 years and one woman, 22 years; sport rank not lower than 1 senior degree). Psychophysiological testing was conducted at five time points using the following methods: hardware and software complex “Diamed-MBS”, ASD (Radix), Lusher colorchoice test (Radix), reaction to a moving object (Multipsychometer), static and dynamic tremorometry (Multipsychometer). Results and discussion. The diagnostic effectiveness of these psychophysiological examination data automated processing complexes were determined by their informative value, the ability to recognize signs of the disease with a so-called reference or benchmark diagnosis. The highest indicators of sensitivity (82.5%), specificity (79.3%) and overall accuracy (80.6%) were found in the Diamed-MBS hardware and software complex. A tendency to decrease in the main indicators, such as heart rate, stress index, activity, well-being, working capacity with a minimum at 3:00-5:00 hours, was revealed. During the day, the possibility of the athletes’ psycho-emotionalstate dynamic assessment during the day (somatic and psychological components) was evaluated according to the parameters of heart rate variability, electrosomatography and bioelectrography. The dynamics of psychological and psychophysiological diagnostics indicators was of the multidirectional nature, which does not allow us to assert unequivocally about the negative impact of daily rhythms on the condition of athletes. All athletes showed negative results in one way or another at different intermediate diagnostic points, but by the end of the study they managed to compensate and reach the results of the primary diagnosis. Conclusion. The diagnostic efficiency of complex screening diagnostics when using hardware and software complex “Diamed-MBS” is 80.6%, which is 25-35% higher than the same parameter for similar devices. No negative psychological and psychophysiological effects of stress stimulation on daily rhythms of athletes were defined.
