[Neurovascular reactivity in vibration disease]

It is pointed out that neurovascular derangements are among the earliest and primary changes in individuals exposed to the effect of vibrations. The manifestations of vasoconstriction with a tendency for generalization prevail. Angiospasm associated with hypopallesthesia, hypalgesia and hypothermy in miners with continuous service in hard rocks processing, using high-frequency drilling hammers, constitute in many aspects the complex of symptoms, typical of the vibration disease. It is emphasized that neurovascular reactivity might be assumed as having certain diagnostic-prognostic significance provided it is estimated against the background of the other clinical data and indicators.
