HU You-jia~1,LI Guang~1,ZHENG Jun-bao~1,WU Ping-jian~2(1.Department of Biomedical Engineering,Zhejiang University,Hangzhou 310027,China;2.Mediplus Development Co.,British Virgin Islands,United Kingdom)  
The complete quantitative vibration perception testing device was presented for evaluating the function of nerve fibres,here was designed based on neurology principles and psychophysical methods.The vibration perception threshold was determined by the up and down transformed rule(UDTR) and forced-choice algorithm.The effect of subjective perception can be filtered by the psychophysical algorithm.The device can be used in double-blind experiments, and also operated by individual operator.Two series of trials were carried out with this device.Data analysis proved its repeatability,reliability and accuracy.
