ABSTRACT
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+/-3.68micronV. 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+/-5.21micronV. 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.
