✦ Synopsis

Twenty-four volunteers worked four times in a laboratory under realistic conditions for 80 min with a relatively intensely vibrating planesander and a less intensely vibrating band-sander (each sander twice). Immediately before and after exposure, the left and right third finger was measured for vibratory sense with a 100 Hz rod-vibrameter and for widthund depth-sense by means of an apparatus modified after Carlson The reproducibility of the parameters was poor: coefficients of intra-individual variation were 20 to 60 % After using the plane-sander the threshold of the width-sense in the right hand increased relative to the effect of the bandsander by 17 % of the pre-exposure value; in the left hand no increase was found The thresholds of the depth-sense and vibratory sense showed no change The study suggests that brief vibration exposure below the ISOguideline may cause some reduction of sensibility One should be cautious in applying these tests An exposure-free interval of at least several hours is recommended when studying chronic effects of vibration exposure.
