FIELD: medicine.SUBSTANCE: group of inventions relates to field of medicine and medical equipment. Electroencephalogram (EEG) is registered during image examination. Frequency range of EEG from 4 to 30 Hz is isolated and divided into bands with width 0.5 Hz, comparison of signal levels in them is performed. Bands with change of signal level depending on image type are detected. During treatment session amplitude of EEG in selected range is measured. Visual and tactile canals of BFB reinforcement are used: in case of positive one - electric skin irritation is eliminated, in case of negative - image is worsened and electric skin irritation is increased. Said method is realised by means of hardware complex. Into complex introduced is unit of electric skin impact, which realises tactile signal of feedback. Device for analysis of measured data is made with possibility of isolation bands with 0.5 Hz width from EEG frequency range and performing amplitude-frequency analysis in them. Device for observation of patient's visual activity and its measurement contains electrodes of EEG registration.EFFECT: method extends arsenal of means for correction of vision disorders.2 cl, 4 dwg, 2 ex |
