Nerve conduction velocity distribution in normal subjects and in diabetic patients without clinical neuropathy. I. Motor nerve.
A computer-assisted collision method to evaluate motor conduction velocity distribution of the ulnar and external peroneal nerves in normal subjects and in insulin-dependent and non-insulin-dependent diabetics without clinical signs of neuropathy is described. Distribution curves were sigmoidally (bimodally) shaped in normal and in insulin- and non-insulin-dependent subjects. In insulin-dependent patients, motor conduction velocity of the peroneal nerves was globally impaired, whereas of the ulnar nerves it was normal. In non-insulin-dependent patients, slower conduction velocity was involved in both nerves.
