Peripheral circulatory and nervous response to various frequencies of local vibration exposure

by Nohara S, Okamoto K, Okada A

The influence of local vibration exposure on peripheral circulatory and nervous functions was studied in order that the vibration frequency which has the greatest effect on the body could be determined. The response to various vibration frequencies (30, 60, 120,240,480 and 960 Hz) under constant acceleration (50m/s2) was examined in humans. The hands of five healthy men were exposed for 1 h to local vibration at various frequencies. The skin temperature did not change significantly at any frequency. The finger blood flow decreased after vibration exposure (60 and 480 Hz, p
