The purposes of this study were to compare the sensitivities of two tests, QST(quantitative sensory test)and PPG(photoplethysmography) in normal adults. We evaluated the sensory thresholds of QST and PPG and diabetes mellitus test in 17 normal adults. The finding of this study can be summarized as follow :The diagnostic sensitivities of QST was similar to PPG. There is a direct correlation between the amount of Blood sugar and parasympathetic nerve in ANS. Concluded that the QST might be complement to NCS for early of diabetic polyneuropathy. A new diagnostic approach, QST was introduced and exploited for diagnosis. This study provides support for PPG performed a ANS analysis.
