[Early signs of disease caused by vibration in miners of the Far North and Arctic region].

Premorbid condition represented by slightly expressed signs caused by vibration was studied in miners of northern mines and showed the absence of clear clinical manifestations in comparison with the vibration disease. Functional studies showed the disordered skin sensors, peripheral hemodynamics and muscles of the disordered skin sensors, peripheral hemodynamics and muscles of the upper limb: decreased distal blood flow rate in the upper limbs, lowered static endurance of the forearm muscles. Statistic and discriminative analysis helped to differ the groups of miners with preclinical and clinical manifestations of vibration disease by means of using the functional parameters.
