Objective: Although nerve conduction studies (NCS) of the lateral femoral cutaneous nerve (LFCN) and somato-sensorial evoked potentials (SEP) generated by the stimulation of LFCN (LFCN SEP) are the main tools in the electro-diagnosis of meralgia paresthetica (MP), these techniques have certain limitations. The analysis of a late response (LR) obtained from the vastus medialis muscle and evoked by the stimulation of LFCN (LFCN-LR) would be useful in the diagnosis of MP. In this preliminary study, we aimed to determine the usefulness of this putative late response.
Material and Methods: Twenty patients with MP (18 unilateral, 2 bilateral), 16 patients with unilateral L3 radiculopathy and 26 controls were included in the study. LFCN-LR, LFCN NCSs and SEP analyses were performed in patients with MP and L3 radiculopathy.
Results: A late response was recorded at 15.7±1.0 ms in control subjects. The onset latency of LFCN-LR was significantly prolonged in patients with MP (20.1±4.1). Asymmetric prolongation of LFCN-LR was the most sensitive parameter in patients with unilateral MP (17/18).
Conclusion: Although the potential effect of indirect excitation of the femoral nerve could not be eliminated, our results suggest that LFCN-LR may be a useful test in the diagnosis of MP.Keywords: Meralgia paresthetica, lateral femoral cutaneous nerve, somatosensory evoked potentials, late responseT Klin J Med Sci 2004, 24:336-344
