Abstract

Warm and cool thresholds before, during, and after exposure to vibration, were investigated. Twelve healthy male volunteers with a mean age of 26.3 years participated in the study. Subjects were screened to exclude those with prior regular exposure to hand-transmitted vibration, diabetes, vascular or neurological disorders and injuries to the right hand. The experiment was performed in a room with ambient temperature of 23°C. Subjects were acclimatised for 10 minutes before the skin temperatures were measured. During the pre-exposure period, there is no significant difference in thresholds between the control condition and the 125-Hz session. With 125-Hz vibration, warm thresholds increased over the five periods and also over the three periods during application of vibration.
