ESTIMATION OF HAND FUNCTIONAL OVERSTRAIN RISK CONNECTED WITH DYNAMIC AND STATIC EFFORTS, LOCAL VIBRATION

Abstract

In terms of works for grinding of metal products with machine and manual tools, a method of revealing and prediction of risk (R) of hand functional overstrain connected with dynamic and static efforts, combined with local vibration exposure has been stated. A risk indicator was the index of hand joint pains (IP) which generalized quantity of localizations, frequency and expressiveness of pains. Dynamics of IP and R during the years of work were predicted on the basis of an integrated estimation of fatigability of work movement complexes, a work regime and a level of local vibration.
