Abstract
Both epidemiological (1) and experimental studies (2) suggest that the ISO 5349 frequency weighting curve may not place enough weight on exposure to mid-range vibration frequencies (i.e., 100-500 Hz). Data from rat vibration studies demonstrated the risk of developing vibration-induced vascular dysfunction is greater in rats exposed to vibration at 125 or 250 Hz than in rats exposed to vibration at 62.5 Hz (3). Vibration also affects peripheral nerve function. However, the frequency-dependent effects of vibration on injury to the peripheral nervous system have not been examined. The goal of this study was to characterize the frequency-dependent effects of repeated vibration exposures (i.e., 10 days) on peripheral nerve function and biology.
