Abstract

Scientific Background: One of the matters in clinical neurophysiology is evaluation of theproximal conduction time along the lumbar plexus. Objectives: Instead of investigating onlydistal segment of the nerve from the groin as is generally done we aimed to investigate bothproximal and distal parts of the nerves originating from the lumbar plexus.Material and Methods: In this paper different proximal conduction methods were studied in109 healthy adult human subjects by measuring proximal motor conduction time of femoral,obturator and genitofemoral nerve along the lumbar plexus using both by using lumbarmagnetic and peripheral electrical stimulation and by using the H-reflex methods in adductorand quadriceps muscle group. The anatomical parts of the study were applied on 20 humanadult cadavers, dissecting femoral, obturator genitofemoral nerve and roots proximally.Results: The total distance from ligamentum inguinale to spinal level was 392.4±13.3mm infemoral nerve. The total distance was approximately 382.8±11.1mm in obturator nerve andthe total distance was approximately 353.1±12.5 mm in genitofemoral nerve. With the Hreflex method, using the distance obtained from the cadaver, femoral and obturator nerveproximal conduction velocity were determined to be 62.5±6.1 m/sec and 53.6±7.4 m/sec,respectively. Using lumbar magnetic stimulation and the peripheral electrical stimulation,proximal conduction velocities in femoral, obturator and genitofemoral nerves weredetermined to be 59.1±13.3m/sec, 52.7±14.9 and 58.7±0.8 m/sec, respectively.Conclusions: No statistical differences were found between the proximal conductionvelocities elicited by both methods. Either approach is preferable to evaluate proximalconduction time.

Özet

Lomber pleksus'un proksimal iletim zamanının değerlendirilmesi, klinik nörofizyolojininönemli sorunlarından birisidir. Bu çalışmada, genellikle yapıldığı gibi, lomber pleksusunsadece distal parçasını araştırmak yerine, hem distal hem proksimal parçasını araştırmayıamaçladık. Bu çalışmada 109 sağlıklı erişkin olguda, periferik elektrik uyarım ve lombermanyetik uyarımla genitofemoral, obturator ve femoral sinirin motor iletim zamanı ölçülerek,ayrıca adduktor ve kuadriseps kas grubunda H refleksi metodu kullanarak farklı proksimal ileti metotları çalışıldı. Çalışmanın anatomik kısmı 20 yetişkin kadavrada femoral, obturator,genitofemoral sinir ve proksimal kökler diseke edilerek uygulandı. Ligamentum inguinale'denspinal seviyeye ortalama toplam mesafe femoral sinirde 392.4±13.3mm, obturator sinirdeyaklaşık olarak 382.8±11.1, genitofemoral sinirde ise 353.1±12.5mm olarak ölçüldü. H-refleksi metodu ile, kadavradan elde edilen mesafe kullanılarak femoral ve obturator sinirinproksimal iletim zamanı 62.5±6.1 ve 53.6±7.4 m/sn olarak saptandı. Periferik elektrik uyarımve lomber manyetik uyarım ile femoral, obturator ve genitofemoral sinirin proksimal ileti hızısırası ile 59.1±13.3, 52.7±14.9, 58.7±0.8 m/sn olarak ölçüldü. Her iki metotla da proksimalileti hızları arasında istatistiksel olarak farklılık gözlenmedi. Her iki yaklaşım da olgulara göreproksimal ileti hızını değerlendirmek için tercih edilebilir.
