Abstract
The objective of the study: To evaluate the effectiveness of the treatment in patients with the occupational chronic mercury intoxication and vibration disease, related to the local vibration exposure using pulsed magnetic stimulation. Materials and methods: The study involved 20 patients with the chronic mercury intoxication and 24 patients with the vibration disease. The treatment was carried out using a magnetic stimulator. The study was conducted with the approval of the ESSC HE SB RAMS Ethics Committee. Electroencephalography with the recording of the evoked potential, electroneuromyography, algesthesia and vibration sensitivity, hands temperature, psychological examination was carried out after and before treatment. Results: The improvement of interaction of subcortical-stem structures and associative areas of the frontal and temporal lobes of the brain after treatment of patients with the chronic mercury intoxication is observed. The time of the wave of afferent excitation at the level of the cervical spinal cord and the time required for the activation of neurons near field somatosensory cortices and associative areas of the brain are decreased. The previously reduced speed of the pulse on peripheral nerves in the hands has restored. According to the psychological examination decreased levels of emotional tension, anxiety is decreased and patients’ psychological comfort is improved. The time of the afferent excitation wave at the level of the cervical spinal cord, subcortical structures and the time of central holding in patients with vibration disease is decreased. The previously reduced speed of the pulse of the distal tibial and median nerve on the ulnar nerve in the elbow joint has restored. Indicators characterizing the state of memory, attention and psychoemotional sphere are improved. Conclusion: thus, using pulsed magnetic stimulation can increase the efficiency of the treatment process of occupational diseases and improve patients’ functional and psycho-emotional state.
