Method for estimating occupational skills of personnel working in various application fields

FIELD: medicine.

SUBSTANCE: method involves carrying out physiological examination with electroencephalogram recorded. Cognitive evoked potential method is additionally applied as neuropsychological examination for detecting hard and latent organic brain lesions causing central nervous system pathological disorders. An additional psychophysiological examination is carried out with vision analyzer test, visuomotor response test being applied for obtaining estimations of selection, discrimination, noise immunity and muscle endurance index, movement coordination, response to moving object and integral estimation of attention and ability for perceiving significant information, motor analyzer rapid response production estimation, estimation of nature of cardiovascular system response to given psychoemotional loading estimation. The examination is sequentially carried out as primary control when hiring personnel, as intermediate control in following a training course and emergency training. Psychological testing is of multi-purpose nature. To achieve it, a set reliable tests and methods of prognostic and substantial validity are applied, including intellect and project-building tests and standardized self-reports. When making decisions concerning professional validity based on test and examination results, risk group is selected from operation personnel.

EFFECT: enhanced effectiveness of occupational skill assessment.

 

The invention relates to medicine, in particular, to psychology and health, namely the means of determining the suitability of personnel for recruitment and can be used in industries involving hazardous production requiring special responsibility, rescue operations, special conditions of service, etc. there is a method of assessing the competency of personnel in personnel selection, described in the book the authors Bazarova T.YU, Eremina EL personnel Management. M: UNITY, 2001, pp. 227-231. The known method involves sequentially conducting preliminary interviews, completing the application form, interviewing recruitment (interview), testing, reference checking and employment history, medical examination (if there are special requirements to the health of the candidate, depending on features) and the decision on acceptance or denial of employment.

The disadvantage of this method is that it is designed for selection to work, not associated with dangerous industry, or with extreme circumstances and do not require special responsibility.

There is a method of assessing the competency of personnel in personnel selection, described in the above book, pp. 328, 329.

The known method methodologically based on the simultaneous use of tre theoretical approaches to the study of the manifestations of man, namely, psychometry, which divides human behavior on a number of more or less independent categories and provides ways to measure, to compare between people; socio-psychological and anthropological principles describe the behavior that allows you to capture specific facts to highlight the typical ways of behaving in specific conditions, to train specialists in the field of behavioral psychology categorized, structured observation of organizational behavior; clinical observation, giving the opportunity to compare individual manifestations at the moment with the fact that clinicians consider the best for this person. It includes modeling of key moments, and development system evaluation criteria in specific activities, testing various complementary techniques and exercises assessment not only experts, but also by trained observers, with cross (assessment of each participant multiple observers, each observer multiple participants) assessing actual behavior with the identification and description of qualitative characteristics, the characteristics of the individual style of activity being evaluated.

The disadvantage of this method of evaluation is the tsya the fact, what is estimated in the first place, "technical capabilities" of the person performing this work, and do not count it neuropsychological features.

There is a method of assessing the competency of staff during the recruitment process, described in the above book, pp. 336-337.

There is a method of evaluation involves modeling the most common business situations through special exercises, obtaining information about professional goals and values, organizational skills, communication skills and personal qualities from the evaluated through interviews, psychological testing, with the aim of obtaining information about the qualities that affect human behavior in organizations, and professional effectiveness, organizational and managerial games and drawing conclusions.

The disadvantage of this method is that it also focuses mainly on the definition of business qualities, while the recent increase in cases of nervous breakdowns when the people of their duties in an emergency or difficult circumstances.

There is a method of determining the suitability of staff in the selection of personnel, developed in the Department of internal Affairs of the Nizhny Novgorod region and is described in p. the Russian Federation No. 2089101 "method for determining the suitability psihologicheskoi training of employees of internal Affairs bodies" class. And 61 5/16 In, 12.08.93, publ. 10.09.97.

The known method involves estimating the parameters of the cardiovascular and respiratory systems, attention and speed of reaction before and after mental and physical stress, in the process of filing by the sudden impact of psychogenic and omegawiki factors, additionally determine the electric resistance, the correct solutions, memory, ability to think logically, the time taken to perform the individual steps of the entire job, the indicators scored and the sum determined by the professional suitability and psychological preparation. In the preparation of the impact of visual, audio, tactile and scent stimuli, and also black and yellow visual stimulus.

The disadvantage of this method is the fact that with its help it is estimated, basically, a healthy individual's ability to exercise and decision-making in complex situations, but not taken into account the possible "problems" in his state of the Central nervous system that can lead to serious consequences.

There is a method of determining the suitability of fire described in the same as. the USSR №1445695 on CL And 61 5/16 In, 14.05.84, publ. 23.12.88.

The known method is that the measure p is the parameters of the cardiovascular and respiratory systems before and after physical and emotional stress, the distribution of attention and performance, mobility of nervous processes and the average value of the forward reaction, the obtained performance is correlated with the diagnostic table of coefficients summarize these factors and recognize the examinee suitable fire if their sum is greater than zero.

The disadvantage of this method is that actually using it is only determined by the ability to physical exertions.

There are a number of ways a professional evaluation staff recruitment, described, for example, as the USSR №1607777 (operators with the assessment of the dynamics of the nervous system on various motor reactions in response to various positive color stimuli), No. 1452515 (operators with the assessment of the cost of executing the task by the values of maximum heart rate), No. 2164776 (checked on the dynamics of indicators collectively significant questions which cause the deviation of the following measured characteristics: galvanic skin response, frequency thoracic and diaphragmatic breathing, heart rate, reactions motor activity and voice in response to the test with three different groups on the importance of the issues). However, these known methods generally determine any physiological capabilities of the test (No. 1607777, No. 1452515), or his motivation for choosing the profession (No. 2164776), but not neuropsychological status.

There is a method of assessing the functional state of the CNS, are described in p. the Russian Federation No. 2153847 on CL And 61 5/16 In, 09.01.97, publ. 10.08.2000,

The known method is carried out by acting on the test light and sound stimuli with the proposal in the shortest possible time and with maximum accuracy to establish the coincidence of the frequencies of these stimuli, and the difference in the coincidence of these frequencies is not more than 1.5 Hz and the time is 30 s, consider the state of the Central nervous system the norm.

The disadvantage of this method is its low efficiency because of the rather "one-sided and incomplete surveys.

There is a method of assessing the competency of staff, described by the RF patent №2128471 "Method of evaluating the effectiveness of the interaction of aircraft crew members" on CL And 61 5/16 In, 14.05.98, publ. 10.04.99.

The known method includes the individual psycho-diagnostic testing of each member of the crew of an aircraft (AC) in the process of their professional training, the testing is carried out in two stages, between which conducted a series of games aimed at building the skills of interaction between members of the flight crew on the ug with each other and the crew of the aircraft with other services in situations close to real, and the crews for the games completed on the initial results of individual testing, and after the games advanced exercise group psychodiagnostic testing by picked crews, while in the process of re individual psychodiagnostic testing reveal the personality component of the professional characteristics (SSP) each member of the flight crew on the four levels of functioning: member of the flight crew of the aircraft; a member of the flight crew - a crew member of the aircraft; a member of the flight crew the flight crew; a crew member of aircraft - navigation information in the process group of psychodiagnostic testing reveal personality characteristics crew (OCE circulation) also on the four levels of functioning: the crew of the aircraft - aviation-transport system; the crew SU - SU and the environment; the crew of the aircraft - navigation information and information about the technical condition of the aircraft; the flight crew the flight crew, then on the basis of the comparative analysis revealed SSP and OCE circulation taking into account the results of the games carry out a comprehensive assessment of the efficiency of interaction of each member of the flight crew.

The disadvantage of this method is that it is designed only to determine the personality characteristics of the crew, i.e. its interaction with the services and ranks inside of the crew.

The closest to the technical nature of the claimed is a method of assessing the competency of staff during the recruitment process, as described in the USSR №1346131 "Method of selection operators" on CL And 61 5/16 In, 14.08.84, publ. 23.10.87 and selected as a prototype.

The known method is that the conduct physiological examination of the subject, recording its physiological parameters such as blood pressure (measurements) and the currents of the cerebral cortex (EEG) before and after the execution of psychological tests that define the professional qualities of staff and represents the intellectual load in the form of logical tasks that specify the audio channel speed with increasing complexity, then establish the relationship between the quality of the load, i.e. the solution of logical problems, and the change in measured physiological variables, and if the load is performed within the acceptable for this activity, and physiological parameters remain within normal limits, the test is considered suitable for carrier operations.

The disadvantage of this method is not very efficient, because it will help in the selection are evaluated only physiological parameters and is not taken into account condition the CNS, could lead to critical situations to nervous breakdowns and, as a consequence, errors in the work and heavy on the consequences of industrial accidents.

The aim of the proposed method is to increase the efficiency of selection and enabling its use for mass determination of competency.

This objective is achieved in that in the method of assessing suitability of personnel for various activities, including physiological examination of registration of EEG, psychological testing to determine the professionally important qualities of the staff and the decision on the competency on the results of inspection and testing, according to the invention spend physiological examination with recording of electroencephalograms, complementing its method of cognitive evoked potentials, and perform as neuropsychological to identify gross and underlying organic brain lesions, contributing to the pathology of the Central nervous system, in addition conduct psychophysiological examination of the personnel, including the assessment of the visual analyzer, the assessment of visuo-motor response and assessment response selection, evaluation, discernment, assessment of attention, the noise immunity evaluation, and the evaluation index of mysen the th stamina, quality assessment of motor coordination, evaluation of the response to a moving object and an integrated assessment of the properties of attention and perceptual abilities relevant information, estimate the speed of the motor capabilities of the analyzer and evaluation of the nature of the reaction of the cardiovascular system at a given emotional burden, the survey consistently perform as the primary control device to work as periodic monitoring and maintenance of the learning process and emergency response training, psychological testing perform multidimensional, which uses a set of methods and tests with reliability, predictive and content validity and including intellectual and projective tests, and standardized self-report, when deciding on professional qualifications according to the results of inspection and testing allocate risk from operational staff. Perform neuropsychological examination using the method of cognitive evoked potentials for detection of organic brain lesions and possible pathology of the Central nervous system in conjunction with the psychophysiological examination, including assessment of the visual analyzer, the assessment of visuo-motor reaction and assessment of response selection, evaluation, discernment, evaluation, attention,evaluation, noise immunity, as well as evaluating the indicator muscle endurance, quality assessment of motor coordination, evaluation of the response to a moving object and an integrated assessment of the properties of attention and perceptual abilities relevant information, estimate the speed of the motor capabilities of the analyzer and evaluation of the nature of the reaction of the cardiovascular system on the set of psycho-emotional stress, when carrying out surveys consistently as the primary control device for the work and as periodic monitoring of the learning process and emergency response training with multidimensional psychological testing using a set of methods and tests with predictive and content validity and reliability, with selection based on test results and testing "at risk" significantly to increase the efficiency of a professional evaluation staff and to use it widely for the evaluation of professional qualifications of members of large groups or in the selection of employees in the power structure.

In comparison with the prototype of the proposed method is new, differing from it in additional to the recording of electroencephalograms using the method of cognitive evoked potentials as tools neuropsychological examinations to identify organic porazeni the brain and CNS pathology, performing psychophysiological examination including an assessment of the visual analyzer, the assessment of visuo-motor reaction and assessment of response selection, evaluation, discernment, evaluation, attention, evaluation, noise immunity, as well as evaluating the indicator muscle endurance, quality assessment of motor coordination, evaluation of the response to a moving object and an integrated assessment of the properties of attention and perceptual abilities relevant information, estimate the speed of the motor capabilities of the analyzer and evaluation of the nature of the reaction of the cardiovascular system at a given emotional burden, the implementation of surveys consistently as the primary control device for personnel, periodic monitoring and maintenance of the learning process and emergency response training, conducting multidimensional psychological testing with a set of methods and tests with predictive and content validity and reliability, and selection of the "risk group", providing together a more effective assessment of professional suitability and the possibility of its use for the assessment of large groups or large numbers of candidates for certain types of work.

The applicant unknown solutions, has named the distinctive characteristics that provide the components collectively achieve the specified result, he therefore believed that the inventive method a professional evaluation staff for various activities meets the criterion of "inventive step".

The inventive method a professional evaluation staff for different activities can be widely used in medicine, particularly in psychology and health at work in the professional selection of workers for employment in the industry associated with increased risk and liability, for example, under contract to the army, security forces, emergency, to work at nuclear power plants and the like, and therefore meets the criterion of "industrial applicability".

The inventive method a professional evaluation staff for various activities is as follows.

Spend physiological examination of registration of EEG, which is supplemented by the method of cognitive evoked potentials and perform as neuropsychological to identify gross and hidden organic lesions of the brain, causing a possible pathology of the Central nervous system. Additionally conducting psychophysiological examination of the personnel, including the assessment of the visual analyzer, the assessment of visuo-motor reaction and assessment of response selection, evaluation, discernment, evaluation, attention, evaluation room is ustoichivosti, as well as evaluating the indicator muscle endurance, quality assessment of motor coordination, evaluation of the response to a moving object and an integrated assessment of the properties of attention and perceptual abilities relevant information, estimate the speed of the motor capabilities of the analyzer and evaluation of the nature of the reaction of the cardiovascular system on the set of psycho-emotional stress. When this examination is conducted sequentially as the primary control device to work, periodic monitoring and maintenance of the learning process and emergency response training. Perform multidimensional psychological testing, which uses a set of methods and tests with predictive and content validity and reliability and includes intellectual and projective tests, and standardized reports. When deciding on the competency on the results of inspection and testing allocate risk from operational staff. The inventive method a professional evaluation staff for various activities as follows.

Neuropsychological testing is conducted using the method of computer electroencephalography in conjunction with the program Brainloc and method of cognitive evoked potentials.

Computer electr is encephalography (EEG) - this method studies the bioelectrical activity of the brain arising in the course of its activities, with computer data processing and a full analysis of the EEG. Computer EEG assesses functional (working) state of the brain as a whole and its individual regions and is used to identify gross and hidden organic lesions of the brain, such as a lesion (tumor, cyst, etc.), inflammation (encephalitis, meningitis, etc.), traumatic diseases (moved traumatic brain injury), clarification and identification of epileptic foci with their localization and view the intensity of the pathological lesion and its trajectory through the areas of the brain.

The EEG is a recording of the activity of neurons of the cerebral cortex. Each neuron (nerve cell) enclosed in a membrane (shell), which has the potential of rest, comprising about 60-70 mV, which is a prerequisite for the normal functioning of the neuron, generating them electrical activity. When slowing down or cessation of metabolism, electrical activity of neurons is reduced and then completely stops, indicating clinical and biological death of the brain. EEG technique allows to detect the earliest a hundred the AI of various diseases of the brain, and to assess the functional state of the brain.

In conjunction with the method of EEG using the method of three-dimensional localization of pathological lesions brain - program Brainloc. This program allows you to learn and see localization in brain structures revealed when writing computer EEG foci of pathological activity in epilepsy, tumors, injuries, insults, etc. in the following models:

1) inside the volume of the rotating head (or brain) for the spatial representation of the conguration of sources;

2) schematically layered images of brain structures;

3) orthogonal isometric projections of the head with the indication of the trajectory of moving sources in time.

The program Brainloc allows to accurately diagnose, prescribe effective treatment and, if necessary, to help specialists another profile (neurosurgeons, oncologists) to specify the diagnosis and surgical intervention or radiation therapy.

The program Brainloc makes it possible to identify abnormal activity areas in the initial stage, which is not detected on computed tomography and magnetic resonance imaging, revealing only the lesions destruction of cells.

The method of cognitive evoked potentials (EP) is based on the fact that the activities of the analyzers (bodies Slu is a, vision, sensitivity) involves specific receptor (i.e. cells that perceive sound, light, pain, etc.) and pathways (nerve) of different areas of the cortex responsible for the above analyzers. Receptors are specific for each type of sensitivity mini-transformers, which convert the energy of the stimulus of the external environment in electrical potential that can be recorded in the form of the action potential using equipment and special programs. Even a small loss at any level sensitive path leads to the change of potential. In the occurrence of the action potential are of great importance postsynaptic excitatory and inhibitory potentials. Impulse along the nerve fibers is transmitted by changing the action potential (AP) of neighboring neurons; the speed of propagation of PD depends on the condition and type of nerve fibers. On the modality of the presented stimulus evoked potentials (EP) are divided into visual, auditory, somatosensory, tactile, olfactory, gustatory, vestibular, kinesthetically, cognitive. Visual and stem EAP widely used in the early diagnosis of systemic diseases, assessing the effectiveness of conservative treatment in the diagnosis of the vegetative state of the brain and functional with the standing of the Central nervous system. Somatosensory EP used to evaluate the recovery of nerve conduction paralyzed limb (stroke, cerebral palsy, polineiropatia, fractured roots in the cervical and lumbar osteohondroza) and determination of the level of destruction pathways.

For psychophysiological examination methods for the assessment of psychophysical parameters using their computerized complexes, for example, diagnostic complex of the firm "Neurosoft".

This can be a complex that includes the following tests:

- assessment of the visual analyzer in the critical frequency of fusion of light flickering;

- assessment of the visual and Central fatigue on visual-motor reaction;

- assessment of the reaction of choice for simple visual-motor reaction;

- assessment of the reaction of discernment on visuo-motor reaction;

- assessment of attention on visual-motor reaction;

- assessment of noise immunity on visuo-motor reaction;

- assessment of the response to a moving object on the balance of excitation and inhibition in the nervous system;

the assessment rate of muscular endurance in the degree of fatigue of the motor analyzer;

- quality assessment of motor coordination;

- integral evaluation of the properties of attention and ability to comprehend relevant information in the red-black the tables Schulte-Platonov;

- estimate the speed of the motor capabilities of the analyzer using the tapping test;

- identify the nature of the reaction of the cardiovascular system at a given emotional load by removing the electrocardiogram - samples with emotional stress. The test is conducted in the following sequence: the search for first digit (black and red); arithmetic score in the mind; the search for scattered digits from 1 to 60. The duration of the sample, including the time of exposure and the recovery period is 20-25 min; continually assesses the subjective and the objective state of the patient, and in the end is the interview with the psychologist.

Psychophysiological examination of the organizational staff includes:

primary (input) control at the device to work or transfer to another position with the diagnosis of psycho-physiological state (i.e. the state before the disease);

- periodic monitoring;

- support the learning process and emergency response training.

When survey data are used survey (headache, pain in the heart, associated with stressful situations); the patient card, where the marked rise in blood pressure, hypertension, ischemic heart disease; the presence of abnormalities on the ECG, is not associated with the above diagnoses (CHD, N Is L, GB).

Psychological testing is multidimensional and has the purpose of diagnosis of professionally important qualities of the staff, optimization of socio-psychological climate and the regulation of conflicts and analysis of the impact of human factors on the occurrence of accidents. It is carried out with the use of a package of methods and tests that are robust and predictive and content validity. This set of tests is a "test battery", which is created on the basis of prior occupational studies, which is a psychological analysis of the activities and highlights individually-psychological features of the professionals associated with professional success.

Such characteristics as reliability and validity are the most important parameters.

The reliability of the test reflects the accuracy of the measurement of individual psychological traits with this test. The validity of the test is its complex characteristics, giving information about what measures this technique and how well.

Predictive validity describes the test as allowing to assess the quality of predictions of the test results of this test. Content validity assessment of the content and full is the method from the point of view of the characteristics measured in the field of mental qualities.

In your package methods in multidimensional psychological testing includes, in particular, the following tests and procedures:

1) predictive tests;

2) projective tests such as the method Luscher color test);

3) standardized self-reports, such as tests, questionnaires, for example:

the questionnaire for the study of the motives and attitudes of professional activity (questionnaire relations);

- personal questionnaire Cattala (16-factor personality questionnaire);

- psychosemantic diagnosis of latent motivation.

Intellectual tests are objective and directed generally to the evaluation of the abilities (intelligence, memory, attention etc). When running smart tests the examinee must solve logic, arithmetic, spatial tasks.

Methodology Luscher allows you to define and describe the signals of personality:

- a set of selected human behavior and the means by which he achieves from the surrounding desirable for self-assessment of his personality and appears in their eyes as confident or helpless person. Election role has its psychopathological and neurotic climax with psychosomatic symptoms, which are divided into 4 types of behavior: active, calm, persistent, obshitelina-responsive.

ODA is wilted relations is used to study motivational and installation of the sphere of the individual employees.

Personal questionnaire Kettel is used to diagnose patients with temporal adaptation or personality disorders that do not contain serious pathology. The data obtained with it are of a pronounced social character and appreciate the person as a member of the team, revealing character traits such as openness and closedness, efficiency and resourcefulness, integrity and responsibility. This assessment is especially important in the diagnosis of personality specialist due to the fact that the activities of the staff is a group character and its success depends on the coherence of the group.

Psychosemantic methods latent motivation is intended to reveal the content of the structure of human needs, motives of various kinds of activity, conscious and unconscious, and is aimed at diagnosis is not so stable behavioral traits of personality as a dynamic, situational due to the characteristics of consciousness.

According to the results of inspection and testing is made a conclusion about the suitability of the subjects to perform a certain job. "Risk group" in terms of inappropriate indicators for this study is highlighted in the conclusion separately. For them, recommendations for their possible adaptation (normalization) or adequate use in each the x fields.

Example.

Surveyed X., 55-year-old worker 156-th plant (the main production of the Mayak chemical combine). Addressed independently with complaints of headaches, confusion, that was making mistakes at work and forget that you need time to pass report etc.

From the anamnesis of life - without somatic pathology.

Objectively: in the mind. Hypomnesia. Several American - weak convergence, asymmetry nasolabial folds, (+) trunk boars reflex. Right-sided pyramidal insufficiency. Reduced coordination.

When EEG revealed: prominent diffuse changes in the bioelectrical activity of the brain with low functional activity of neurons in the cortex, focality in the right fronto-parietal region, lowering the threshold of convulsive readiness.

On cognitive evoked potentials revealed: the decline of RAM 3 times from age norms, reduction of the processes of perception and identification 3 times from age norms, reduction of the adaptation processes.

Taking into account the identified focal symptoms the patient was sent for an MRI scan, which revealed foci of demyelination (decay), cortical atrophy in the frontal areas.

In the study on the instrument Psi Test methods: reaction of discernment, choice reaction, the reaction on a moving object is detected serious violations of EQ is velenosi processes of excitation and inhibition in the nervous system, also revealed a pronounced decrease in muscle endurance. Psychological tests revealed: on the operational level, the overall rate of mental activity is slowed down, the memory is reduced, the exhaustion of mental processes is moderately disturbed (narrowing of the scope, difficulty concentrating), the inertia of thought processes is reduced. In General, the level of mental health of the patient is moderately reduced. Also significantly changed the emotional-volitional and personal sphere that is characterized by:

- increased sensitivity to external factors;

- emotional instability;

- lower efficiency;

- self-doubt;

- pessimistic assessment of their own situation;

elements hypochondriac commit.

Thus, the resulting survey data allow us to evaluate the possibility of the patient as

restricting the ability to work 1st degree,

limiting the ability to learn and communicate 1 degree.

Other spheres of life is not limited.

The patient should be suspended for a complex of rehabilitation measures, such as:

1) the course of treatment by a neurologist;

2) psychological support;

3) when is luccheni neurophysiological indicators of the patient can perform the work, not associated with severe mental and emotional stress, or to perform the same work with reduced working hours or reduce the amount of work.

In comparison with the prototype of the proposed method of assessment of professional suitability of staff for different activities is more efficient and allows for the assessment of whole groups or masses of candidates for certain positions.

The way a professional evaluation staff for various activities, including physiological examination of registration of EEG, psychological testing to determine the professionally important qualities of the staff and the decision on the competency on the results of inspection and testing, characterized in that conduct physiological examination with recording of electroencephalograms, complement method cognitive evoked potentials and perform as neuropsychological to identify gross and underlying organic brain lesions, contributing to the pathology of the Central nervous system, in addition conduct psychophysiological examination of the personnel, including the assessment of the visual analyzer, the assessment of visuo-motor reaction and evaluation of selection, evaluation, discernment, evaluation of error-correcting the STI, as well as evaluating the indicator muscle endurance, evaluation, coordination, evaluation of the response to a moving object and an integrated assessment of the properties of attention and perceptual abilities relevant information, estimate the speed of the motor capabilities of the analyzer and evaluation of the nature of the reaction of the cardiovascular system at a given emotional burden, the survey consistently perform as the primary control device to work as periodic monitoring and maintenance of the learning process and emergency response training, psychological testing perform multidimensional, which uses a set of methods and tests with reliability, predictive and content validity and including intellectual and projective tests, and standardized self-report when deciding on the competency on the results of inspection and testing allocate risk from operational staff.

SUBSTANCE: method involves forming signals as tests requiring solution. The tests are shown with frequency changed proportionally to the frequency they are solved. The number of tests is set to be the same in the cases of recovered and tired state. General amount of time spent for finding solution for given number of tests and the number of tests having right solutions are determined in each state. Mental fatigue degree is evaluated from relative change of mean time needed for finding the right test solution using a relationship like (Tm.r- Tm.t)100%/Tm.t, where Tm.t = Tsum.t/Kr.t, Tm.r = Tsum.r/Kr.r, Tm.t is the time spent for finding the right answer in tired state, Tm.r is the time spent for finding the right answer in recovery state, Tsum.t is the total time spent to solve given number of tests in tired state, Tsum.r is the total time spent to solve given number of tests in recovered state, Kr.t is the number of right answers to the tests in tired state, Kr.r is the number of right answers to the tests in recovered state.

EFFECT: reliable estimation of fatigue degree.

FIELD: medicine.

SUBSTANCE: method involves examining extremity muscles corresponding to their reflexosegmental links to visceral organs under study. To do it, patient extremity is set in a position, which causes maximum number of muscle fibers to contract. Then, the muscle is brought to isometric contraction state by applying pressure with patient counteraction to this pressure. Pressure applied to the extremity is increased in 1.5-2 s. The patient showing inability to hold isometric stress, changed function of organ under test is to be diagnosed.

EFFECT: accelerated way to detect viscera function disorders.

SUBSTANCE: method involves carrying out ultrasonic scanning examination of subclavian artery over its whole extent in physiological arm position with arterial blood pressure being measured in the middle one third of the arm. Next, when applying compression tests, blood circulation parameters variations are recorded in distal segment of the subclavian artery with arterial blood pressure being concurrently measured. Three degrees of superior thorax aperture syndrome severity are diagnosed depending on reduction of linear blood circulation velocity and arterial blood pressure compared to their initial values. Mild one takes place when linear blood circulation velocity reduction reaches 40% and arterial blood pressure 20% of initial level, moderate one when linear blood circulation velocity reduction reaches 70% and arterial blood pressure 50% and heavy one when linear blood circulation velocity reduction is greater than 70% of initial level and arterial blood pressure is greater than 50% to the extent of no blood circulation manifestation being observed in the subclavian artery.

EFFECT: high accuracy of diagnosis.
