Abstract

A thirteen-year prospective study of an open cohort of forest workers aimed to report the changes in vibrotactile perception thresholds (VPT) observed at the fingertips of a subgroup of workers who reported for a required annual medical examination on 1990, 1995, and 2003. Vibrotactile thresholds were recorded at the fingertips with the subject seated, and with his forearm supported horizontally in a comfortable position. Skin temperature was recorded at the fingertips before the measurements commenced. and was maintained at ?27°C. Twenty-eight percent of the study group reported numbness in the hands at study inception, at which time the prevalence reported by the complete cohort was also 28%. The changes in acuity of this finger from 1995 to 2003 are found to have no statistical significance, except at 4 Hz.
