Biofeedback and neurofeedback procedures are realized on the basis of the „physiological mirror” principle, thereby the patient has a literal opportunity to see and hear nuances of his state change, manifested in change of various physiological processes.

Functional biocontrol based on biofeedback provides training the skills of psychic self-regulation. Supplied set of biofeedback procedures is meant to normalize the functional status of the various body systems (CNS, ANS, cardiovascular system, respiratory system, locomotor apparatus) by developing skills of relaxation, reducing muscle tension, normalization of heart rate and its variability, reducing the tone of vessels of different caliber, normalizing blood pressure and parameters of cerebral and central hemodynamics, changes in the ratio of EEG rhythms and their topical characteristics, etc.

Procedures can be used to manage current psychoemotional state of sportsmen, employees engaged in stresses professions, students to reduce the pre-launch (pre-examination) stress and anxiety, to mobilize and form required attitude for goal achievement, to eliminate negative emotions in case of nervous breakdown, and to restore a positive psychophysiological state.

Various biofeedback training screens


  • trends, scales, diagrams, geometric figures (1), graphic arts, images, slides, videos;
  • animation and various game plots (2);
  • linear, three-dimensional and noise-like distortions and conversions of images, slides and videos (3);
  • morphing of images;
  • information screensavers and instructions during biofeedback training (4).



  • various music fragments, sounds of nature, MIDI-splitter, voiced information, noise-like distortions depended on the successful execution of biofeedback training;
  • information messages and instructions during biofeedback training.

Diversity of visual forms of BFB signals presentation and flexible settings make each procedure attractive and stimulate the patient’s motivation to targeted state change.

Software is meant for data analysis and trends visualization, which display cardio-cyclic dynamics (averaging from cycle to cycle) of different calculated parameters for cardiovascular, vegetative and central nervous systems in one time scale and provides an option of visual evaluation of their interconnection at synchronous record of 16 EEG derivations, 16 super slow brain activity derivations, 6 REG derivations and signals by 4 polygraphic channels from the list: ECG, EOG, EMG, respiration effort, photoplethysmogram and temperature.

Software provides evaluation of physiological changes in response to provoking actions in order to detect weak and compensatory elements in organism’s systems and ensures carrying out statistical and spectral analysis, building hypnograms and scattergrams, which display distribution of selected quantitative parameters over set study fragments, and generates automatic protocol with formalized description and table data with initial state and significant changes connected with functional tests carrying out.

Analysis of trends, which display cardio-cyclic dynamics of parameters change, provides:

  • Consideration of possible effect of vascular factor in epilepsy;
  • Diagnostics of cerebrovascular disorders during functional tests for hyperventilation;
  • Diagnostics of syncopal states.

Change of physiological parameters on trends of cardio-cyclic dynamics in response to provoking actions (hyperventilation).

In 30 seconds after hyperventilation (HV) start, the rheographic index REG (7) is significantly decreased, in 3 minutes of HV there are changes on EEG – sharp increase of slow-wave activity (5, 6) with paroxysmal manifestations (4) and sharp decrease of alpha-activity level (3).
