Abstract:
Objective To observe the changes of electroneurogram in patients with diabetic peripheral neuropathy(DPN).Methods The electroneurophysiological data of 78 patients with DPN,including motor nerve conduction velocity(MCV),sensory nerve conduction velocity(SCV) and F-response,were observed.Results Among the inspected 468 nerves of 78 patients with DPN,166 nerves' MCV were slowed down,and 39 nerves with the decrease of MCV were accompanied by the prolongation of distal delitescence.The abnormality rate was 43.8%.175 nerves' SCV were also reduced,75 nerves were tested with no potential elicited,and 26 nerves with the decrease of SCV were accompanied by the prolongation of distal delitescence.The abnormality rate was 58.9%.The F-waves of 66 nerves(64.7%) in 102 tested nerves were abnormal,and 12 nerves' F-wave time chronodispersion(11.8%) increased.Conclusions Electroneurogram is a sensitive and characteristic inspection in the diagnosis of DPN,and the diagnostic sensitivity may be improved if multiple parameters are used together.
