【Abstract】 Objective To explore the early diagnostic value of quantitative sensory testing (QST) in diabetes with peripheral neuropathy (PNP).Methods The nerve conduction velocity (NCV) and QST were examined in 46 diabetic patients, and their results were compared. Results The abnormal ratio of NCV in 46 patients was 72.8%. 32 cases (69.6%) were diagnosed as diabetes with PNP. While using QST, the abnormal ratio was 91.3%. 40 cases (86.9%) were diagnosed as diabetes with PNP. There was a significant difference between two methods ( P<0.05).Conclusions QST is more sensitive than NCV in diagnosing diabetes with PNP. Thermal testing is more frequently abnormal than vibratory testing and NCV, which suggests that small nerve fibers are more vulnerable than large fibers.更多还原
