The Laboratory is set the Complex of Rehabilitation psychophysiological training with biofeedback (BFB) "REHACOR-T" production NPKF " Medicom MTD."
The complex is a system consisting of a 4-channel polygraph diagnostics of psychophysiological indicators of the client, a set of sensors, a personal computer with a dual-monitor system (one monitor - for the customer, the second - for the expert) and the software package for biofeedback training, recording and processing of data , development of new training and diagnostic procedures.
| The equipment of "REHACOR-T" in this configuration, which is available at the Department of Psychology V.N. Karazin Kharkiv National University, you can take the information about 7 physiological processes - electrical brain wave activity (electroencephalogram, EEG), electrical activity of the skin (ESA, formerly known as galvanic skin response or GSR), electrical muscle activity (electromyogram, EMG) activity of the thoracic and abdominal breathing (recursion breathing or RB), heart (electrocardiogram - ECG and its individual components – heart rate - HR, heart rate variability - HRV), the lumen of the artery (photoplethysmogram - PPG) and temperature. |

For each recorded physiological parameters have been developed specific trainings-scenarios allowing to the examined to receive tasks and visually-auditory information about it (setting) current state and, consequently, the success of their own psychological attempts to affect it in the desired direction.
For example, if the client under stress (such as a student in the exam) has cold and sweaty hands, the heart of "jumping out of my chest" and "confused thinking", in the course of biofeedback training, he can by representing the situation of the exam, try with methods of anger management, self-hypnosis or just intuitively raise the temperature of the hands, slow the heart rate and cause a concentrated state of mind. From the computer in real time, he will receive the signal of the temperature of hands, heart rate and rhythm of the dominant EEG (concentrated attentive state corresponds to the beta rhythm).
Biofeedback training program are written in such a way that except neutral information about the results on the monitor (for example, finger temperature reflected in the animation fluctuating temperature gauge with numbers) a person received even more, positive reinforcement of successful and negative - of unsuccessful reactions. That is, except for the thermometer, the screen can be replaced by any pictures, can be a video, animation, sound, and while picture and sound quality will deteriorate, brake, be masked when failure of the training, and improved - for successive reactions. Video and audio series are designed using the principles of art therapy in the form of video games, providing motivating, causing interest information.
The result of the passage of biofeedback therapy is the improvement of general condition, afferentation of the body and awareness of psychophysiological integrity of all processes occurring in it, getting rid of stagnant and current psychological problems, improvement of stress tolerance, self-control, quality of life and more. In particular, many studies proved the effectiveness of biofeedback therapy for such clinical (in the majority - psychosomatic) problems such as: asthma, stuttering, enuresis, headaches and other pain syndromes, attention deficit and hyperactivity, sleep disorders, reactive depression, hypertension, epilepsy, various neurotic symptoms, scoliosis, paresis, addiction, etc. In the field of non-clinical biofeedback successfully used to improve the learning ability of children and adults, increasing stress tolerance in sport, management, and other professional fields, disclosure of creativity, behavior modification, increasing self-confidence, self-willed training, relieve fatigue and increase working capacity in order to improve the general non-specific sense of self and life satisfaction.
Unlike the others, in fact often similar, psychotechnics and types of psychotherapy – yoga, meditation, holotropic breathing, hypnosis, body-oriented therapy and tanatotherapy etc., using adaptive biocontrol progress is much faster and it is objectively fixed - reducing electrical capacity at the electromyogram reflects the degree of muscle relaxation, proper equipment records the rhythm and the degree of intensity of the respiratory and cardiovascular systems, electronic sensor shows the temperature change of limbs on each one hundredth degree, and all of this is demonstrated on-line, recorded in the computer and mathematically processed.
For example, you can get the average (arithmetic mean, median, mode) of the parameters of the initial background, training phases, rest phases, stages for instructions and final background stage, calculate the standard deviation, and other statistics, make graphical analysis, track the dynamics from session to session, and it will not be the placebo effect, or the illusion of a different sort.
