Abstract

Neuropathy in diabetes mellitus is well known and usually takes form of polyneunopathy. Diagnosis of polyneuropathy is sometimes difficult because clinicians are unable to demonstrate the objective counterpart -of subjective symptoms. To perform sensory and motor conduction study is relatively easy and does not give much discomfort to the patients and therefore is a good measure to .evaluate physiologic change of nerve. Nerve conduction study was done in median and ulnar nerves of the 112 diabetics, whose ages ranged from 28 to 77 years, mean age being 54. 1 years. Sensory and motor conduction were compared between 33 control, 53 diabetics without neuropathy, and 59 diabetics with neuropathy. All the modality of conduction (velocity, distal latency, amplitude, duration etc.) showed decrase of function in diabetics with neuropathy, but in diabetics without neuropathy the decrease of function was generally insignificant statistically. Diabetics with history of more than 5 years showed decrease of function in all modality while those with less than 5 years did not. Decrease of conduction was seen in diabetics with more than 200mg/100ml FBS or 400mg/100ml PP2 level. 21. 4% of all patient had electrophysiological criteria of carpal tunnel syndrome in one or both wrist. Nerve conduction study is thought to be useful in diagnosing and monitoring neuropathy and evaluating the result of therapy objectively.
