[Determination of finger vibrotactile threshold and its significance in patients with hand-arm vibration syndrome].
Vibrotactile sense threshold (VST) of the end of the middle fingers in 97 patients with established or suspected hand-arm vibration syndrome and 60 healthy controls was determined, and finger VST contour and vibration damage curve were plotted. Results revealed the most sensitive frequencies of VST were 8 Hz for the patients and 125 Hz for the controls, respectively. VST in the patients with hand-arm vibration syndrome was higher than that in the controls, and the threshold shift was initially at high frequency with a "V" dip at 125 Hz and 250 Hz. So, the authors think determination of VST is an auxiliary method used for diagnosis of hand-arm vibration syndrome.
