"Basic" software suit contains biofeedback procedures for wide application by various parameters and their combinations including the following:
- heart rate
- galvanic skin response
- envelope electromyogram
- electroencephalogram (2 derivations)
- electrocardiogram (1 derivation)
- brain blood circulation (a special sensor and impedance adapter are required)
- central hemodynamics (a special sensor and impedance adapter are required)
- Along with biofeedback procedure, there are options of psychophysiological state and psychoemotional stress evaluation – stress testing.
HR training is a basic one for mastering the skills of relaxation, self-regulation and consentration.
Procedures on heart rate increase allows eliminating the deficit of parasympathetic affect of ANS and increasing organism resistance to disorders of cardiovascular system work in response to psychoemotional stress.
Procedures of HR variability increasing are recommended for arterial tension normalization, for physical efficiency increase and overall health improvement.
HR training also increases body defenses level and neutralizes stress responses and psychoemotional overexertion, accompanied with vegetative balance disorder.
Skin temperature increase training allows lowering the excessive tone of arteriola vascular walls by means of lowering the activity of sympatic section of ANS, and is applied for zonal thermoregulation improving (the increase of temperature of legs and arms peripheral zones) under the conditions of diseases manifested in reduced blood supply of these zones.
This training is a basic one for Shultz auto training mastering.
Is used to treat chronical obstructive involvement of respiratory system, bronchial asthma, some circulatory disorders, vegetative-vascular dystonia syndrome, neurosal and neurosis-like syndromes.
The purpose of respiratory biofeedback training is to form adequate respiratory stereotype with simultaneous switch to diaphragmal respiration type, which provides not only improvement of lungs work, but also influence on other, particularly psychic, functions and increase of functional reserve of the organism.
Blood circulation parameters
Procedures of blood circulation parameters regulation – tone of arteries of different caliber (by PPG systolic wave amplitude and pulse transit time) and cardio-cycles periods (by RR-interval of ECG signal) are used for autonomic nervous system functional state normalization, for correction of arterial tension indices, blood filling and etc., mainly during rehabilitation after excessive loads.
Alpha training is oriented to improve stress resistance, to achieve profound psychological relaxation, and also to activate creativity.
Alpha-theta training is used to form skills of quick and effective attention concentration.Beta- and beta-theta trainings are used to correct attention deficit hyperactivity disorder. EEG-EMG-training is used to achieve the state, combined maximumal attention concentration against the background of profound muscular relaxation.
Is indicated to decrease general and psychoemotional stress by means of decreasing excessive muscle activity (muscle relaxation skill), to form stereotype of optimal correlation of various muscle groups (to improve voluntary control of movement activity), to correct movement disorders of central and peripheral character of various geneses by means of decreasing spasticity and hyperkinetic activity.
Evaluation of psychophysiological state and psychoemotional stress – stress testing
During stress-testing different stress stimuli can be applied: audio, visual, somatosensory.
The training detects specific organism responses to various irritants for identification of the most labile parameters and their most effective use in BFB-training.
The picture shows trends, which demonstrate pronounced change in some values (mainly the ones reflecting the tone of cardio-vascular system resistive vessels) in response to a stress stimulus.
"Professional" software suit includes additional to the "Basic" software suit multiparametric biofeedback- and neurofeedback-procedures, which use multichannel record of EEG and other parameters, including the following:
- slow cortical potentials (SCP neurofeedback)
- functional brain asymmetry
- rhythmical brain activity
- zonal differences
- EMG, Skin conductance, ECG, GSR, PPG, temperature, breathing, brain circulation and central hemodynamics
Alpha rhythm and EEG zone differences optimization
Used for skills training - relaxation and EEG structure normalisation, cortex and corticosubcortical optimum relationship tonus recovery by means of alpha rhythm increase in the occipital area in relation to the central-frontal area.
At zone differences index increase, a videoclip “waterflooding” decreases, digital indicator value increases, figure enlarges.
An alpha rhythm optimisation is connected with a graphic curve increase.
Brain functional asymmetry increase with multiparametric control
Training to achieve a special functional state required for solving different tasks involving concentration and motor actions accuracy, for example, shooting or managing manipulators and controlled mechanisms.
Training forms a skill of the arbitrary reconstruction of the brain functional asymmetry – spectral power increase of an EEG activity in a frequency range 10-14 Hz in the left temporal lobe at preparation for action and at the moment of its execution.
Multiparametric control trends display increase of spectral power values within 10-14 Hz in derivation Ò3-À1 (left frontal) as compared to values of Ò4-À2 derivations at the background (blue) and working (red) training stages, and change of functional asymmetry in derivations Ò3-À1 (left temporal lobe) at the background (blue) and working (red) training stages and change of HR and Skin conductance during training.
Tremor decrease with the muscle and emotional tension control
Pathologic hand tremor control training contributes to mastering a skill of arbitrary muscle and emotional tension decrease
Hand tremor (essential tremor, secondary tremor, etc.), bradykinesia, caused by neurological diseases, for example Parkinson disease.
Balance training maintaining erect position on the wobble platform
Used to train the skill of steadiness and movement co-ordination in sport and in order to decrease the ataxic syndrome symptoms, the orthopedic trauma consequences and other neurological disorders, which prevent from maintaining erect posture.
Wireless movement activity sensor can be attached onto the wobble platform, which is often used during fitness classes in sportclubs.
The picture shows an example of change of movement sensor signal, parameters trends in time and changes on training screen.
Operator performance training simultaneously with tracing and logic task solving.
Used to study various aspects of operator performance with relation analysis of physiological signals patterns and indicators of operator activity efficiency.
Can be used to select individuals of definite professions, with exclusive standards for psychophysiological characteristics connected with monotonous work and necessity of maintaining attention concentration.
Training the skills of stress resistance using somatosensory stimulator
Used to form the skill of stress resistance in healthy people (sportsmen, students, security agencies employees, etc.), and for therapy of patients with neuroses with symptoms of phobia and anxiety.
The skill is formed by means of training on suppression of excessive autonomic activation (galvanic-skin response change) in response to stress stimulus presentation (moderate pain stimulation).
