ABSTRACT
BACKGROUND:
Meralgia paresthetica(MP) which is characterized by paresthesias and sensory impairment without motor weakness in the anterolateral aspects of the thighis produced by compression of the lateral femoral cutaneous nerve(LFCN). Even though the diagnosis of MP is mostly based on the clinical symptoms, electrophysiologic study is mandatory to confirm the disease objectively. It has been known that Somatosensory evoked potential(SSEP) study of LFCN is a simple and very useful method to evaluate MP, so we studied SSEP of LFCN in normal adults and offer normal values. MATERIALS ANDMETHODS:
Thirty six normal adults(23 males and 13 females) ages from 21 to 73 years old(mean+/-SD42.06+/-15.74) were studied SSEP of LFCN bilaterally. The stimulation site was anterolateral aspect of thighs and the recording site was Cz'.RESULTS:
The mean values(msec+/-SD) of LPo, SPdegree, LN, and SN1 of all subjects were 35.10(+/-2.42), 33.80(+/-2.4), 43.68(+/-1.88) and 42.16(+/-2.12) and the mean values(msec+/- SD) of DPo, DNl and DA(tw+/-SD) were 1.3O(fi1.14), 1.52(+/-1.38) and 0.32(+/-0.33).CONCLUSION:
For the diagnosis of MP, comparison of latency difference between both sides is more reliable than simple value of latency itself because of individual differences of body types. According to our results, the latency difference should be less than 2 msec and the amplitude difference was less than 1.6 times in normal adults.
