초록

Objective: To find a new method and usefulness of study on sensory nerve conduction of lateral sural cutaneous nerve (LSCN).
Method: The 60 extremities of 30 adults without peripheral neuropathy were placed in a prone position. Next, each subject was administered with an antidromic stimulation at a point 3 cm lateral from the center of the popliteal fossa. With the aid of active electrodes, the sensory nerve action potentials (SNAPs) were recorded at points 10 cm inferior and 1 cm lateral to the stimulation site. The method of sensory nerve conduction study suggested by Campagnolo et al. was performed simultaneously, to compare of the frequency of SNAPs and the amplitudes.
Results: For the sensory nerve conduction study of the LSCN suggested in this report, SNAPs were obtained in 49 extremities, with a revelation rate of 81.7%. The mean amplitude was 11.91±3.68μV. In the results of the tests suggested by Campagnolo et al., the SNAPs were obtained in 29 extremities, with a revelation rate of 48.3%. The mean amplitude was 8.37±5.21μV. Significance testing of the electrodiagnostic method recommended in this study revealed that many SNAPs were observed for the LSCN, with statistically significant action potential amplitudes. Conclusion: This study presents the new method and reference values of sensory nerve conduction for LSCN, which is thought to be useful in electrodiagnostic studies to diagnose entrapment neuropathy.
