The excellent AAEM Equipment and Computer Committee technology review article on compact battery operated nerve conduction velocity devices used the name ''neurometer'' to refer to one of these devices. 3 ''Neurometer'' is the registered trademark for a brand of neurodiagnostic products manufactured by Neurotron, Inc. Neurotron, Inc., does not now nor have we ever manufactured devices which measure conduction velocity. This confusion probably arises from portable nerve conduction devices that were marketed under the name ''electroneurometer'' until several years ago. These devices were limited to the crude assessment of latency.
The Neurometer brand computerized automated neurodiagnostic devices employ completely different technology. A neuroselective constant current electrical stimulus is used to objectively quantify and monitor the functional integrity of more than 90% of the sensory nerve fibers-including the large and small myelinated and unmyelinated fibers. 3 The reliability and efficacy of this type of methodology have been documented by over 300 peerreviewed publications which report on the application of cutaneous electrical stimulation as a quantitative test of sensory function. 1,2,[4][5][6][7] Please inform your readers about this error in order to avoid further confusion.
