ارزش تشخیصی پتانسیل های بر انگیخته سوماتوسنسوری در بیماری مرآلژی پارستتیکا(Meralgia paresthetica)

Background: clinical background, but electrophysiological evaluation is helpful in confirming the diagnosis. Weinvestigated the Somatosensory Evoked Potentials (SEPs) of the lateral femoral cutaneous nerve(LFCN) of the thigh. Because of lack of knowledge in case of its diagnostic utility in our country, thisstudy is performed.Although the diagnosis of Meralgia paraesthetica (MP) is always made based onMethodsHospital in Tehran (2009 – 2010), who have clinical symptoms and signs consistent with a diagnosisof MP underwent bilateral studies of SEPs elicited by stimulation of the LFCN of the thigh.: In this cross sectional study, we entered sixty consecutive patients referred to the LoqmanResultsThe specificity of the SEPs test was 98.3% (95% CI, 91.0%– 99.9%) for the diagnosis of MP.: SEPs was abnormal in 32 (53.3%) patients, all of whom were clinically diagnosed with MP.Conclusionof MP.: Our findings suggest that SEPs is an extremely useful test for “ruling out” the diagnosis
