"The purpose of this study was to determine the accuracy of measuring median nerve distal sensory latency using a portable digital electroneurometer. The results from the digital electroneurometer were compared to formal nerve conduction studies in eleven subjects (12 hands) with probable carpal tunnel syndrome and forty subjects (40 hands) with no symptoms of carpal tunnel syndrome. There was a high correlation (r=.92) between the latencies obtained from the electroneurometer and the onset latencies measured by formal nerve conduction studies. The mean difference between distal sensory latencies for matched pairs of latency measurements was 0.09 (+- -0.21 ms). The digital electroneurometer is an objective and accurate instrument for obtaining distal sensory latencies. The electroneurometer would be useful in a variety of occupational and clinical settings for screening of peripheral neuropathy where formal nerve conduction equipment and technical expertise may be unavailable."
