HERNANDEZ RODRIGUEZ, Héctor  and  LEDEZMA ZITO, Liana. Characteristics of peripheral nervous conduction in rheumatoid neuropathy. Rev Cub Med Mil [online]. 1998, vol.27, n.1, pp.18-21. ISSN 0138-6557.

A number of 20 patients with clinical diagnosis of rheumatoid arthritis sensitive and motor peripheral nervous conduction of the median nerves in the upper limbs and of the common and sural peroneum in the lower limbs was studied. A similar number of subjects was also selected and studied in order to compare the results. Neuropathy in these patients was due, in most of them, to the trapping of the nerves by an inflammatory tissue with segmental dismyelinization as the initial response of the nervous fiber to compression. Results showed a greater alteration of the motor fibers in the lower limbs. The most affected parameter was the duration and latency of the motor action potential, so the neuropathy was classified as a dismyelinating neuropathy.
