COMMON REGULARITIES IN DISORDERS OF CENTRAL AND PERIPHERAL NERVOUS SYSTEM AT THE INFLUENCE OF PHYSICAL FACTORS (LOCAL VIBRATION AND NOISE) ON EMPLOYEES’ ORGANISMS

There are direct and invert correlations between the indices of the electroencephalography and. electroneuromyography in the groups of patient with vibration-induced, diseases and. occupational neurosensoric dullness of hearing. Despite the fact that coincidence of correlation indices was observed in one case only, this fact may testify to the similar influence of physical factors (local vibration and. noise) on the employees' organisms and. it may confirm that the changes may be observed both in central and peripheral nervous system, that is, the whole neurosensoric complex is activated

EVALUATION OF EFFICIENCY OF BIOLOGICAL FEEDBACK TRAINING IN PATIENTS WITH LOCAL VIBRATION-INDUCED DISEASE

The article describes the evaluation of efficiency of the temperature-myographic training in the patients with vibration-induced disease after the local vibration exposure based on the data of the thermometry, the dosed cold sample, the rheography of the upper extremities, the algesimetry, the pallaesthesimetry, the psychological examination to control the changes in the neuropathic pain, the electroneuromyography. It was shown that the training effectively influenced the manifestations of the angiodystonic syndrome as well as to restore the nervous-muscular conducti-vity at the upper and. the lower extremities

Vibration influence on functional activity of nervous system in experimental animals

The production vibration is known to be a powerful stressor which may induce the complex of disorders leading to the vibration-induced disease development. Along with the appearance of the clinical syndromes the neurosis-like, the psychoemotional disorders, the ipochondric, asthenic and asthenovegetative syndromes, the diffuse disorders of the bioelectrical brain activity with the participation of the cortex of the large hemispheres as well as the stem and diencephalic brain structures were observed to occur in the patients with the vibration-induced disease. However, at present there are no clear arguments in favour that namely the exposure to vibration may promote the occurrence of the neurotic disorders, the neurosis-like disorders of psychic activity, the disadaptation signs, the emotional disorders as well as the pathological changes in the bioelectrical brain activity in exposure to vibration. This work aimed to reveal the changes in the central nervous system (CNS) based on the study results of the behavior and bioelectrical brain activity in the animals. The experimental studies were performed using the mature inbreeding rats males. The chronic experiment was performed by means of the modificated vibrostend VEDS-10a, the vibration levels taken corresponded to the exposure in reality to vibration under production conditions. The studies were performed based on 4 study series: for 15 days, one, two, and four months of exposure to vibration. The intact rats were used as the control ones. The animal behavior responses with assessing the motor activity, the orientating and learning as well as the emotional behavior components were observed in the «юрen field». Recording and processing the electroencephalographic data were performed using the electroencephalograph Neuron-spectrum 4 (Joint-Stock Company «Neurosoft», Russia). The information was processed using the standard methods of the variation statistica, statistical processing the data was performed by means of the Packet of Applied Programs EXCEL Packet Office 2003 (in OS «W1NDOWS Xp»), «Statistica for windows - Version 6». The study of the behavior activity in the animals has shown that the increase in the common motor activity, the nonspecific character, the high emotional strain of the negative character, the negative emotional state were found to occur in the rats exposed to vibration, thereto, the orientating and learning activity was at the previous level. The change in the bioelectrical brain activity was characterized by the increase in the slow-wave activity of the delta-range after one month of exposure to vibration and the latent period prolongation of the visual induced potentials (V1P) after 15 days of exposure to vibration

ROLE OF SENSORY CONFLICT IN FORMING OF HEALTH DISORDERS IN EMPLOYEES EXPOSED BY PHYSICAL FACTORS

The article presents the results of the study of psychological status, centra! and peripheral nervous systems, neuromuscular apparatus in patients with vibration-induced, disease and sensorineural deafness of occupational genesis. The dynamics of forming of changes in these systems with the increase of vibration and. noise doses in the experiment on laboratory animals is showed. The results allowed, to supplement and. extend, the ideas about the conception of «sensory conflict»

RESULTS AND PERSPECTIVES OF STUDYING THE OCCUPATIONAL DISEASES IN WORKERS OF AIRCRAFT INDUSTRY IN EAST SIBERIA

The materials of the long-studies among the employees working in the aircraft industry, of both the patients with occupational diseases and the practically healthy persons are discussed in the paper. Using the method of the biological feedback for the vibration-induced disease prevention has been grounded. The preliminary results of the experimental studies using the animals are presented in this paper

ОПЫТ ИСПОЛЬЗОВАНИЯ ТЕХНОЛОГИИ БИОУПРАВЛЕНИЯ В КЛИНИКЕ ПРОФЕССИОНАЛЬНЫХ ЗАБОЛЕВАНИЙ

Biofeedback in toxic encephalopathy in the late period chronic intoxication by mercury and complex toxic substances led to decrease in the EEG changes, performance improvement of the amplitude and latency evoked potentials, in vibration disease – to decrease manifestations of angiodystonia syndrome, recovery of neuromuscular conductivity. The effectiveness of biofeedback is confirmed by changes in subjective measures of the patients.Биоуправление при токсической энцефалопатии в отдаленном периоде хронической интоксикации ртутью и комплексом токсических веществ привело к уменьшению общемозговых изменений по ЭЭГ, улучшению показателей амплитуды и латентности вызванных потенциалов мозга, при вибрационной болезни – к снижению проявлений ангиодистонического синдрома, восстановлению нервно-мышечной проводимости. Эффективность биоуправления подтверждена изменениями субъективных показателей состояния пациентов
