Abstract:
Objective To observe the value of electroneurograms and sympathetic skin response (SSR) in diagnosing diabetic peripheral neuropathy( DPN). Methods The electroneurophysiological data on 36 patients with DPN, including motor nerve conduction velocity (MCV) data, sensory nerve conduction velocity (SCV) data and sympathetic skin response ( SSR) data, were analyzed retrospectively. Results Two hundred and sixteen nerves of 36 patients with DPN were inspected. Among 108 nerves tested for MCV, 32 were found to have slowed down, 8 of them with the prolongation of distal delitescence. The amplitudes of compound muscle action potential (CMAP) induced by stimulation of 4 nerves were found to have decreased. The abnormality rate was 40. 7% . Among 108 nerves tested for SCV, 42 were found to have slowed down, 7 were tested with no potential elicited, and 6 were found to have decreased SCV with the prolongation of distal delitescence. The abnormality rate was 50. 9% . Seventy-two limbs of 36 patients with DPN were inspected. Four patients showed no SSR in both their upper and lower limbs. For 38 limbs of 22 patients, the SSR latency was found to be prolonged and the SSR amplitudes were found to have decreased. The abnormality rate was 63.8% . Among 10 patients without neuropathy, 3 patients' SSR was found to be abnormal, an abnormality rate of 30% . Conclusion Electroneurograms and SSR are sensitive indices for the diagnosis of DPN. Their diagnostic sensitivity can be improved if all the parameters are used together.
