Abstract

Purpose: The F- wave is a valuable measurement that provides information about both the proximal and distal parts of the nerve. Classical F-wave recording methods are performed from the distal muscles of the limb and so are affected from distal pathologies. Nerve conduction velocity of a nerve is affected by the diameter of the nerve. The diameter of a nerve gets thinner as it gives branches and travels distally. So it is expected that the nerve conduction velocity of a nerve is faster in proximal segment of the nerve than the distal part even they are the parts of the same nerve. The aim of this study is to compare the nerve conduction parameters of F waves recorded in proximal and distal muscles innervated by the same nerve which will provide additional information and may be valuable in detecting proximal pathologies accompanying background pathologies affecting the distal nerve.
Materials and methods: Twenty–six healthy volunteers who have normal routine nerve conduction studies are included in this study. The latencies of ulnar and peroneal F-waves of all participants were recorded from the proximal and distal muscles innervated by the same nerve.
Results: F-wave latencies recorded from proximal muscles were significantly later than the ones recorded from distal muscles.
Conclusions: Although the distances travelled by stimulation are shorter in F latencies recorded from proximal muscles, and the segment / branch of the nerve is expected to be thicker and faster, the latencies recorded from proximal muscles were longer than the ones recorded from distal muscles. This may be due to the distance of the recording electrodes effected by subcutaneous tissues in the proximal large mass muscles. One reason for this difference may be that the proximal relatively large mass muscles have higher desynchronization and temporal dispersions.
Key words: F-wave, Proximal F-response, Distal peripheral neuropathy

Abstract

Makale başlığı: Üst ve alt ekstremitede ayni sinir tarafindan inerve olan proksimal ve distal kaslardan kaydedilen f dalgasi: yeni bir yöntem olabilir mi?
Amaç: F dalgası sinirin hem proksimal hem de distal kısımları hakkında bilgi sağlayan değerli bir ölçümdür. Klasik F dalgası kayıt yöntemleri ekstremitenin distal kaslarından yapıldığı için distal patolojilerden etkilenir. Sinir iletim hızı, sinirin çapından etkilenir. Sinirin çapı dallanıp distale doğru ilerledikçe incelir. Yani bir sinirin sinir iletim hızının, aynı sinirin parçaları olsa bile sinirin proksimal segmentinde distal kısmına göre daha hızlı olması beklenir. Bu çalışmanın amacı aynı sinirin innerve ettiği proksimal ve distal kaslarda kaydedilen F dalgalarının sinir iletim parametrelerini karşılaştırmaktır. Bu sinir distalini etkileyen arka plan patolojilerine eşlik eden proksimal patolojilerin saptanmasında değerli olabilir ve ek bilgi sağlayacaktır.
Gereç ve yöntem: Bu çalışmaya rutin sinir iletim çalışmaları normal olan 26 sağlıklı gönüllü dahil edildi. Tüm katılımcıların ulnar ve peroneal F dalgalarının latansları, aynı sinir tarafından innerve edilen proksimal ve distal kaslardan kaydedildi.
Bulgular: Proksimal kaslardan kaydedilen F dalgası latansları, distal kaslardan kaydedilenlerden önemli ölçüde daha uzundu.
Sonuç: Proksimal kaslardan kaydedilen F latanslarında uyarının kat ettiği mesafeler daha kısa olmasına ve sinirin segment/dalının daha kalın ve hızlı olması beklenmesine rağmen proksimal kaslardan kaydedilen latanslar, distal kaslardan kaydedilenlerden daha uzundu. Bunun nedeni, proksimal büyük kütleli kaslarda cilt altı dokuların fazlalığı ve kasın kayıt elektrotlarına uzaklığı olabilir. Bu farklılığın bir nedeni de, proksimal nispeten büyük kütleli kasların daha fazla senkronizasyon ve zamansal dağılıma sahip olması olabilir.
Anahtar kelimeler: F-dalgası, proksimal F-yanıtı, distal peripheral nöropati.
