Medial Femoral Cutaneous Nerve Conduction Study with Distal Stimulation and Recording Technique/Medial Femoral Kutanoz Sinir Iletim Calismasinda Distal Uyarim ve Kayit Teknigi

Objective: To determine the normal values of the newly described distal stimulated medial femoral cutaneous (MFC) nerve conduction study in a healthy population using a wide range of ages and body mass index (BMI) values. Materials and Methods: Distal stimulated MFC nerve conduction studies were performed bilaterally in 144 healthy volunteers with no peripheral nerve diseases affecting the lower extremities according to clinical and electrophysiological evaluations. The volunteers were divided into three groups according to their age: 18-39.9 years (age 1), 40-59.9 years (age 2), and 60 years and above (age 3). They were also grouped according to their BMI: 24.9 or less (BMI 1), 25-29.9 (BMI 2), and 30 or more (BMI 3). Results: The mean MFC amplitude was 5.7 [micro]V on both sides, the mean peak latency was 2.8 ms on both sides, and the mean conduction velocity was 61.5 m/s on the right and 61.9 m/s on the left. The MFC amplitudes obtained on the right and left sides were similar, and the mean amplitude difference between sides was 10.1 [+ or -] 9.1% (0-56.6). A negative correlation was identified between MFC amplitude and age and BMI. Conclusion: This study revealed that the newly described distal stimulated MFC sensory nerve conduction study is repeatable and easily applicable. Keywords: Medial femoral cutaneous nerve conduction, lumbosacral plexopathy, femoral neuropathy Amac: Yeni tanimlanan distal uyarimli medial femoral kutanoz (MFK) sinir uyarim calismasinin, daha genis yas ve vucut kitle indeksi (VKI) araligina sahip olan saglikli populasyonda normal degerlerinin tanimlanmasi amaclanmistir. Gerec ve Yontem: Klinik ve elektrofizyolojik olarak alt ekstremiteleri etkileyecek periferik sinir hastaligi dislanmis 144 saglikli gonullude distal uyarimli MFK sinir calismasi iki yanli olarak yapilmistir. Denekler yaslarina gore 18-39,9 (yas 1), 40-59,9 (yas 2) ile 60 ve ustu (yas 3) olmak uzere 3 grupta siniflandirildi. VKI'lerine gore de 24,9 ve alti (VKI 1), 25-29,9 (VKI 2) ile 30 ve ustu (VKI 3) olarak gruplandirildi. Bulgular: MFK amplitudu sagda ve solda ortalama 5,7 [micro]V, tepe latansi sagda ve solda ortalama 2,8 ms ve ortalama iletim hizi sagda 61,5 m/sn, solda 61,9 m/sn olarak bulundu. Sag ve sol tarafta elde edilen MFK amplitudleri oldukca benzer olup taraflar arasi amplitud farki ortalamasi %10,1 [+ or -] 9,1 idi (0-56,6). MFK amplitudu ile yas ve VKI arasinda negatif baginti vardi. Sonuc: Calismamiz yeni tanimlanan distal uyarimli MFK duyusal s
