Short-distance sensory stimulation technique in the early diagnosis of carpal tunnel syndrome

Amaç. Sinir iletim çalışmalarının normal olması karpal tünel sendromu (KTS) tanısını dışlamaz.Biz bu çalışmada, erken evre KTSde avuçiçi-bilek segmentindeki mesafeyi daha kısa tutup,median sinirin tuzaklanma bölgesi dışındaki, henüz patolojik değişikliklerden etkilenmemiş distalbölgesini çıkararak, KTS tanısında duyarlılığı artırmayı amaçladık. Yöntem. Bu prospektifçalışmada, klinik olarak KTS tanısı konan, konvansiyonel elektrofizyolojik incelemeleri normalolan 41 olguda (66 el), avuçiçi-bilek segmentinde; distal bilek çizgisinden (DBÇ) sırasıyla 8, 7, 6,5, 4 cm mesafelerden uyarım yapılmış, bu mesafelerdeki hız, latans ve latanslar arası farkları(iletim gecikmesi), kontrol grubundaki 34 olgunun (68 el) verileriyle karşılaştırılmıştır. Bulgular.4-5, 5-6, 6-7, 7-8. cm.ler arası latans farkı (iletim gecikmesi) her iki grup arasında istatistikselolarak anlamsız olup (p>0.1); 4, 5, 6, 7, 8. cm.lerdeki hız, latans değerleri her iki grup arasındaistatistiksel olarak anlamlı bulunmuştur (p

Karp al tünel sendromunun erken tanısında kısa mesaf eli duyu iletim tekniği

Aim. Normal results obtained from nerve conduction studies do not exclude the diagnosis ofcarpal tunnel syndrome (CTS). We intended to increase diagnostic sensitivity of nerve conductionstudies in the early stage CTS by stimulating shorter palm-wrist segment, and excluding distalregion outside the entrapment site of the median nerve which is unaffected from pathologicchanges. Methods. In this prospective study, 41 patients (66 hands) with clinically diagnosed CTSwith normal conventional electrophysiologic examinations were stimulated with electrodes placedat 8, 7, 6, 5, 4 cm from the distal wrist crease (DWC) on the palm-wrist segment, and theconduction velocities, latencies, and the differential latencies (conduction delay) were comparedwith those of 34 patients (68 hands) in the control group. Results. Conduction delay recordedbetween 4-5, 5-6, 6-7, 7-8 cm. away from DWC of both groups was statistically insignificant(p>0.1), while the conduction velocities and the latencies obtained from the electrodes placed on 4,5, 6, 7, and 8 cm away from DWC differed statistically significantly between two groups(p
