Abstract
Objective:To explore the diagnostic value of nerve conduction velocity(NCV) and H-reflex in patients with diabetic peripheral neuropathy.Methods:Fifty patients with diabetic peripheral neuropathy served as experimental group and 50 healthy subjects as the control group.NCV of the madian,ulnar,peronea I and tibial nerves were measured and H-reflex was elicited by electromyography.Results:A significant difference in NCV and H-reflex was noted between experimental group and control group.H-reflex and SCV were more sensitive than MCV.The abnormal rate of NCV and H-reflex in experimental group was 46%-72%.The abnormal rate of lower limb was higher than that of upper limb,and that of SCV was higher than that of MCV.Conclusion:Electromyography might be one of reliable and sensitive diagnostic measures for early diabetic peripheral neuropathy.
