[Diagnosis and treatment of polyneuropathy].

The electroneuromyographic examination of patients with the occupational polyneuropathy of the extremities after the exposure to the whole-body and local vibration has been performed with the aim to reveal the diagnostic indices of polyneuropathy severity under stationary conditions. The main diagnostic criteria of polyneuropathy severity have been revealed using the discriminant analysis. The drug gabapentine (tebantine) has been tested as the basic pharmacotherapy.

[Bioelectric brain activity under exposure to vibration].

Patients with vibration disease caused by local vibration and those with the disease caused by general vibration demonstrate similar changes in regulation of central nervous system, as shown by EEG--diffuse changes and locus of pathologic activity mostly in right temporal cortex. Unlike local vibration, the combined one acting long (over 10-15 years) causes more pathologic changes in brain, not only in cerebral cortex, but also in brainstem and diencephalic structures.
