Abstract
Abstract: The earliest and most frequent manifestation of HAVS is limb polyneuropathy with sensory disorders. The study was conducted in order to assess the various types of sensory modality disorders by methods of functional diagnostics in HAVS. The main group of patients with an established diagnosis of HAVS and a control group of healthy individuals who have not worked in harmful and dangerous working conditions during their lives were examined. The methods of computer pallesthesiometry, quantitative sensory testing (QST) and stimulation electroneuromyography were used in the study. A comprehensive study revealed disorders of the perception of sensitivity of various modalities (vibration, pain and temperature), which indicated damage to all types of peripheral nerve structures when exposed to local vibration-unmyelinated fibers (C–type), myelinated (A-beta-type) and weakly myelinated (A-delta–type).
