Abstract
|
|
|
|
Evoked potentials(EP) are kinds of electrophysiological study to gauge the senosry system, which usually carmot be measured on clinical examination, objectively and quantitaively. The limitations of the electrophysiological study on clinical applicat!on include variations of results depending on not only technical and environmental factors but also various physiological factors such as sex, age and height. The effects of technical and environmental factors can be standardized in each laboratory, but not for physiological factors. The importance of physiological factors is emphasized on the posterior tibial nerve evoked potential study, because of long travelling course including both peripheral and central nervous system. There are several reports on this problem, but with a lot of controversies probably due to different point of view and statistical analysis. Furthermore, contrary to many authors, I think the effect of various physiological factors cannot be measured by simple regression analysis because of close correlations between each others. To analyse the complex effect of various physiological factors on posterior tibial nerve evoked potential study, 123 cases(male;55, female;68)of the age more than 20 years old and without definite neurological deficits are studied and analysed.
