Two studies are reported in this paper. The Renfrew depth esthesiometer has been modified to improve the precision of this sensory clinical test for vibration-induced white finger (VWF), by controlling finger pressure. Results from three groups of subjects showed that the esthesiometer could differentiate between the group of industrial workers with stage 2 or 3 VWF in Taylor and Pelmear’s classification (N=16), a control group of industrial workers of similar age without VWF (N=10), and a group of students (N=25). In the second study, it was shown that most vibration during pedestal grinding occurs when restoring the cutting ability of the grinding wheel ("dressing"). An improved dressing procedure has been developed, which reduces the vibration level both during dressing and when grinding the work piece. The procedure also leads to reduced exposure time.
