[The effect of the vibration and noise factor on the physical work capacity and autonomic nervous system function of workers in vibration-hazardous jobs].

An unexampled study was made of the peripheral vegetative incompetence syndrome developing in vibration disease. It is shown that chronic occupational exposure to vibration and noise results in damage to the segmentary apparatus of the vegetative nervous system. Vegetative inadequacies are manifested by impairement of cardiovascular functions. With exposure to vibration and noise, it is the sympathetic portion of the vegetative nervous system that is first affected. The service duration-related progression of the pathological process results in increase of the share of parasympathetic pathology. A change in vegetative regulation adversely affects physical performance in those workers who have come to be exposed to a vibronoise factor over long periods of time.
