Therapeutic possibilities for the correction of cognitive and psychoemotional impairments in patients with post-covid syndrome

The principle of operation of the Synchro-S complex: Biopotentials of the brain are recorded in the monopolar mode with a combined ear electrode from 4 sensors placed on the patient's head in the position of the right forehead, left forehead, right occiput, left occiput. Biopotentials of the brain are amplified, preliminarily analog filtered and digitized. Further, the information is transmitted to the computer through the interface with galvanic isolation. The software package of the complex provides the formation of arrays of incoming signal values, their digital filtering, the conversion of incoming signals into an audio image, the display of these signals in real time on a PC screen, the saving of the entered data on a computer hard disk and their subsequent processing. The generated sound image is fed through a standard audio output to the speaker system or headphones and presented to the patient in real time (Fig. 2).

Method Mechanisms: The technological basis of the LHC method is the feedback principle, when the recorded (in this case physiological) parameter is returned to the source after the necessary transformation. This principle is basic for almost all regulatory processes and is widely used in well-known biofeedback methods (BFB). However, in contrast to BFB methods, in the BAC method, the patient is not faced with the task of arbitrary (cognitive) regulation of the transformed physiological parameter. On the contrary, the therapeutic application of the LHC method is based on the principles of involuntary self-regulation. The content of the concept of involuntary self-regulation is not in the technical or cognitive compensation of disturbed physiological reactions, and in the activation of the natural processes of self-regulation and regenerative functions of the body, which are normally carried out involuntarily, but were suppressed as a result of an unfavorable combination of environmental factors, illness, or individual personality traits.
