It can be performed, for example, in the form of a personal computer such as an IBM PC, including a P11-450 processor, a video adapter with a 3D accelerator, 64 Mb RAM, a sound card, CD-ROM, and system software. Block 7 (figure 2) is intended for the formation of annoying stimuli during removal and analysis of evoked potentials and contains a decoder 10 commands and, connected to its outputs, a node 11 for generating a light stimulus with a light emitter 12, a node 13 for generating a sound stimulus with stereo headphones 14 and a node 15 the formation of a color stimulus with an LED color matrix 16. Block 8 is designed to present the patient with biofeedback signals in the form of visual and / or auditory images that reproduce the game situation or movie fragments, reproductions of the picture Musical fragments. Block 8 can be implemented as a second video adapter connected to a personal computer. An audio tactile music therapeutic device 9 (FIG. 3) is designed to influence sound vibrations on the patient’s body 1 and contains a microcomputer 17, a reproduction unit 18 from the archive of melodies and sounds, a multichannel amplifier of sound frequency 19 and an acoustic sensor seat 26, under the shell 35 of which is in the back and the seat is placed emitters of vibrations of sound frequency. Each gain channel 20-1 ... 20-n of the multi-channel amplifier 19 contains a serially connected controlled attenuator 21 and an output amplifier stage 22. Signal input 24 of each of the channels 20-1 ... 20-n is connected to the output of block 18, input 23 gain control to the output of the microcomputer 17. The outputs 25 of the multi-channel amplifier 19 are connected to the respective emitters of the sound frequency of the acoustic touch chair 26, which are located in the back 27 (Fig. 4) in pairs at a height of levels: a - neck, b - mid cervical vertebrae (C3, C4), c - the median thoracic vertebrae (Th3, Th4), d - the median lumbar vertebrae (ThII, Th12) and d - the apex of the sacrum, corresponding to the anthropological data of a person of average height (170 ... 180 cm). In seat 28 (Fig. 5), the emitters of vibrations of sound frequency are located in pairs in the areas: w - the ischial tubercle, h - the short head of the thigh muscle, and e - the popliteal muscle. Sound frequency oscillators

mounted on the frame 36 of the back and 37 seats under the shell 35 symmetrically with respect to the longitudinal axis of symmetry at a distance of 80 ... 150 mm from it. The emitters of vibrations of sound frequency are made in the form of electrodynamic transducers 32 of electrical vibrations to sound, placed in volume resonators 31, each of which is a wooden box (Fig.6). Opposite the diffuser of each electrodynamic transducer 32 in the elastic coating 33 (soft skin) of the chair 25, a sound channel 30 is made through which the vibrations of the sound frequency are transmitted to the shell 35 in contact with the patient’s body. The backrest frame 36 is connected to the seat frame 37 by a swivel joint 38 and may have an additional support (not shown in FIG. 6), on which the backrest 36 is supported in a horizontal position.

A treatment (rehabilitation) session through training with the use of biofeedback in the declared rehabilitation psychophysiological complex is carried out as follows. Patient 1 is seated in a comfortable position on the acoustic sensor seat 26 so that the back is in full contact with the back 27, and the line of the spine coincides with the axis of symmetry of the chair. If the functional state of the patient does not allow BOS training while sitting, the back 27 can be installed in a horizontal position, and the patient can be placed on his back. The power of all devices is turned on and the operator, depending on the diagnosis and the patient’s condition, on computer 6 synthesizes a biofeedback training scenario, which sets the necessary conditions and parameters for the upcoming training in the form of a sequence of self-regulation stages. The scenario of BOS training includes a number of stages, each of which fulfills a specific goal. The stage of assessing the initial physiological parameters is necessary to characterize the initial background state of the patient and to calculate some indicators that will be used in calculating the set thresholds and to evaluate the effectiveness of the stages of training. The briefing stage is carried out both directly by the operator, and with the help of technical means - by displaying text and graphic information on the monitor of block 8 or by playing sound files by block 18, in which the necessary instructions are recorded. The training stage is the main stage in which the patient is engaged in the training and correction of his condition using the functional biofeedback method, using physiological parameters selected by the operator for biological feedback. The pause (rest) stage is used to rest between the different stages of training and is accompanied by a demonstration of audiovisual programs. The BOS-training session ends with the stage of the final analysis to monitor the effectiveness of the training and the preparation of output documents. The scenario of the BFB training session includes a list of sensors and electrodes connected to the patient, a diagram of their connection to the inputs of the bio-amplifier 3, the sequence of supply of musical fragments and sound signals read by block 18 from the archive of melodies and sounds, the program of exposure to vibrations of sound frequency on the patient's body - functions

changes in the gain of each of the amplification channels 20-1 ... 20-n, the program for color-sound and light stimulation (stimulus on-time, duration, interval between stimuli, amplitude, color gamut of light and color stimuli, frequency, duration, interval between stimuli, volume, musical or speech fragment of the sound stimulus), a list of measured parameters, methods of analysis and presentation of results to the patient using device 8 and the procedure for documenting the process of conducting a treatment session and its results (printing of numerical and graphical results, the formation of a medical report with a diagnosis and treatment recommendations).

After connecting the sensors and electrodes and turning on the power, at first, the operability and proper functioning of all devices of the rehabilitation psychophysiological complex are checked. By supplying test signals, the operability of the sensors and the sub-electrode resistance of the electrodes of block 2, the sensitivity, the frequency band and the gain of each channel of the bio-amplifier 3, the performance of the light and color and sound stimulators of the block 7, the health of the computer 6, block 8 and the audio-tactical music therapy device 9 are checked. Then the session begins Biofeedback training. From computer 6, controller 5 records commands for setting the gain and frequency band of each channel of bio-amplifier 3, parameters of light and color-sound stimuli, parameters of control signals for each of the gain channels 20-1 ... 20-n are recorded in microcomputer 17, a list of musical fragments and sound signals and the sequence of their reproduction by unit 18. In accordance with the scenario of the biofeedback training, the patient is given self-regulation of the corresponding electrophysiological pair through stereo headphones 14 or device 9 Etra. The measured biosignals in real time are analyzed and presented to the patient using block 8, for example, in the form of an image on the monitor screen or in the form of an audio or color signal of block 7, or in the form of exposure to sound vibrations on his body. A biofeedback training session is accompanied by exposure to sound vibrations on selected reflex zones of the patient’s body using device 9, the operation of which will be described below.

The claimed psychophysiological rehabilitation complex for training with biofeedback allows biofeedback training to be carried out on the parameters of the most important physiological processes - electrical activity of the brain, electrical activity of the heart, blood supply, skin-galvanic respiratory reaction, and allows the treatment (rehabilitation) of patients with various pathologies. So, biofeedback training on electroencephalography parameters is used in the treatment of the effects of traumatic brain injuries, cerebral vascular diseases, convulsive conditions, borderline conditions such as vegetative dystonia and neurocircular angiopathies. The effectiveness of biofeedback training on EEG parameters is enhanced by training on a sound channel with closed

eyes using the spatial sound scale of an acoustic touch chair 26. BOS-training on heart rate is used to optimize the balance of the sympathetic and parasympathetic parts of the autonomic nervous system, activate adaptive mechanisms, lower blood pressure in hypertension, to correct some types of arrhythmia, its efficiency is increased due to additional synchronization of the frequency of cardiac vibrations by vibrations of the chair emitters 26. BOS-tren ng the parameters Electrical myography used for the detection and correction of muscle tension, convulsive treatment of phantom pain in amputees, rehabilitation of post-stroke gemoparezah. The effectiveness of such a biofeedback training increases with the additional impact of sound vibrations on various parts of the patient's body. BOS-training on breathing parameters is used in the treatment of chronic respiratory diseases, neurotic and pseudo-neurotic conditions, cardiovascular diseases, and in the treatment of stuttering. The effectiveness of this biofeedback training is enhanced by setting the breathing rhythm using device 9. The biofeedback training on blood circulation parameters can be used for a wide range of circulatory disorders - neurocirculatory dystonia, arterial hypertension, hypotension, and peripheral circulation. The effectiveness of treatment is increased by improving capillary circulation under the influence of mechanical vibrations. BOS-training on the parameters of the skin-galvanic reaction is used in the treatment of diseases of the central nervous system, neurosis, phobia, depressive states, various emotional disorders and increase mental stability. Efficiency is increased due to the fact that with the help of the device 9 an additional verbally setting for self-regulation is given.

Compared with the prototype, the claimed rehabilitation psychophysiological complex allows to increase the effectiveness of treatment using all possible procedures of biofeedback training, due to the fact that when a person is exposed to mechanical vibrations by sound vibrations with appropriate musical fragments, the patient’s training in functional biofeedback is activated, as well as through therapeutic the reflex effect of sound vibrations on the physiological systems of the human body.

An additional therapeutic effect is due to the presence of color-sound stimulation. The selection of musical fragments, speech settings, and color stimuli that favorably affect the patient’s emotional state with a certain rhythm allows you to enter the patient into a state in which biofeedback training proceeds with maximum mobilization.

Audiotactic music therapy device 8 (figure 3) can be used independently for the training of hearing impaired, treatment of functional diseases

nervous system (neurasthenia, fatigue, insomnia, psychogenic functional disorders of the cardiovascular system), respiratory diseases (chronic bronchitis, bronchial asthma), diseases with speech disorders (post-stroke motor aphasia, stuttering), diseases of the genitourinary system and sexopathology (chronic renal failure prostatitis, impotence,

When conducting treatment sessions, the patient is subjected to testing, during which the psycho-emotional state of the patient, the main syndrome at the time of treatment, the response of the patient to musical fragments of different tonality, emotional richness and rhythm and sound signals of a certain frequency are revealed. For objectification during testing, the psychoemotional and functional state is determined by analyzing the parameters of electrophysiological processes, in particular the skin-galvanic reaction, electrocardiography, electromyography, rheography and others. Depending on the test results, a scenario (program) is formed for each treatment session. For example, for the treatment of neurasthenia, the session scenario includes a sequence of musical fragments from the patient’s favorite works performed by their favorite artists or from natural noises (rustling leaves, birds singing, the sound of the sea surf) indicating the place of exposure and the strength (volume) of the sound. For the treatment of diseases of the genitourinary system, the session scenario may contain the parameters of the sound signal (frequency, amplitude, duration of sending and pause, shape of the modulating signal) and the place of exposure (numbers of emitters of the sound frequency of the acoustic touch chair and the sequence of their inclusion).

The script of the session is entered in the microcomputer 17 (markers and the time of inclusion of musical fragments, the parameters of the control signals are recorded). To implement the scenario of the session in microcomputer 17, gain channels 20 — influence channels — are allocated, and for each of them a function is specified in the time – gain coordinates. The patient is seated on an acoustic sensor seat 26 in a comfortable position so that the spine line coincides with the longitudinal axis of symmetry of the chair and the back is in contact with the back 27 along the entire length. The power supply to the multi-channel amplifier 19 is turned on, and the command to play the first one is sent from the microcomputer 17 to block 18 a musical fragment or an audio signal and the inputs 24-1 ... 24-n of the gain channels 20-1 ... 20-n receive signals from block 18, and the inputs 23-1 ... 23-1 gain control signals . From the outputs of the amplification channels 20-1 ... 20-n, the electrical signals corresponding to the musical fragment and the modulating control signal are converted by the corresponding emitters of vibrations of the sound frequency in the back 27 and seat 28 of the chair 26 into mechanical vibrations of the shell 35, which act on the reflex zones around spinal column and have a therapeutic effect, causing and improving capillary blood supply in these

zones, and the reflex effect on the internal organs conjugated to the zones, and the normalization (correction) of the psychoemotional state due to soft massage. In comparison with the prototype, the acoustic touch chair has wider functionality and, due to the complex effect on the human body, a more pronounced effect. The presence of a microcomputer 17 and block 18 with an archive of melodies and sounds makes it possible to realize an almost unlimited number of treatment session scenarios and individualize the treatment strategy for each of the patients. The presence of an acoustic sensor seat 26 with emitters of vibrations of sound frequency and a multi-channel amplifier 19 with a controlled gain in each amplification channel by commands from a microcomputer 17 provides a simultaneous and diverse effect on almost all systems of the human body, which cannot be realized using a prototype device. So, for example, the impact of sound vibrations that simulate the sound of the sea surf or rustling leaves, at the level of tactile sensitivity, sequentially on body parts along the spine from top to bottom and bottom to top with a frequency of 3 ... 5 sec. causes deep sleep without dreams and is effective for relieving anxiety and in the treatment of neurosis and insomnia. The impact on body parts in the cervical and thoracic vertebrae by sound vibrations modulated by control signals that specify the rhythm and depth of breathing is effective in the treatment of chronic respiratory diseases. The impact of sound vibrations on the parts of the body in contact with the seat 28 and in the region of the apex of the sacrum during the reproduction of rhythmic major musical fragments improves the blood supply to the organs of the genitourinary system and has a beneficial effect on increasing potency and treating chronic prostatitis.

The acoustic touch chair 26 (Figs. 4, 5 and 6) provides comfort to the patient during treatment sessions using the device 9. The elastic coating 33 allows to increase the contact area of the patient’s body with the back 27 and the seat 28. The possibility of changing the position of the back 27 relative to the seat 28 and its fixation contributes to the adoption of a comfortable posture by the patient. The placement of emitters of vibrations of sound frequency at the levels a ... e in the back 27 and in the areas w ... e of the seat 28 allows you to have a differentiated effect depending on the pathology and implement various treatment methods.
