Abstract

The effectiveness of the new vibrotactile perception threshold (VPT) measurement equipment was evaluated by collecting data from Japanese workers having exposure to hand-arm vibration, comparing VPTs of HAVS free workers with those of contained in ISO 13091-2:2003, and comparing VPTs between persons with and without HAVS for Japanese workers. The study subjects comprised twenty-seven Japanese male workers who were exposed to hand-transmitted vibration. Seventeen workers were engaged in road maintenance as public servants (Group 1), and the rest (ten workers) were engaged in forestry work (Group 2). Four (24%) workers in Group 1 and nine (90%) in Group 2 reported they had some dysesthesia in fingers and these dysthesia were regarded as being related to vibration exposure. The results also show that the mean VPT values for the subjects are statistically significantly higher than ISO references on all fingers at 4Hz.
