Pulsed Light Stimulation in a System of the Aviation Specialist State Correction

Abstract

This article focuses on the problem of the preservation of visual acuity and fatigue prevention in professional activity which requires high responsibility. The implementation of the method of brain photostimulation in the system of aviation personnel rehabilitation has been suggested following the investigation of visual analyzer stimulation by pulses of red, green, and blue light in the α-rhythm range. The goal of the present study was to improve vision and general psychophysiological state and to determine the length of the photostimulation course required to achieve a reliable effect. The duration of the sessions of electrostimulation was 10 min daily for several days. The effectiveness of the stimulation has been evaluated before and after the session using the WAM questionnaire and an alternative psychophysiological scale. It has been found that the course of stimulation of visual analyzer with blue, green, and red light pulses at the frequency of 10–16 Hz led to an improved psychophysiological state of the subjects. The repeated exposure to photostimulation had a cumulative effect and led to a significant improvement in well-being of all the subjects who underwent the photostimulation course of at least 6 sessions.
