Abstract

Aim. Normal results obtained from nerve conduction studies do not exclude the diagnosis of carpal tunnel syndrome (CTS). We intended to increase diagnostic sensitivity of nerve conduction studies in the early stage CTS by stimulating shorter palm-wrist segment, and excluding distal region outside the entrapment site of the median nerve which is unaffected from pathologic changes. Methods. In this prospective study, 41 patients (66 hands) with clinically diagnosed CTS with normal conventional electrophysiologic examinations were stimulated with electrodes placed at 8, 7, 6, 5, 4  cm from the distal wrist crease (DWC) on the palm-wrist segment, and the conduction velocities, latencies, and the differential latencies (conduction delay) were compared with those of 34 patients (68 hands) in the control group. Results. Conduction delay recorded between 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 (p0.1); 4, 5, 6, 7, 8. cm.’lerdeki hız, latans değerleri her iki grup arasında istatistiksel olarak anlamlı bulunmuştur (p<0.001). Sonuç. KTS tanısını doğrulamak için yapılan elektrofizyolojik incelemede, avuçiçi-bilek segmentinde, mesafenin daha kısa tutulup, uyarımın DBÇ’nin 4 ve/veya 5 cm distalinden yapılması, karpal tüneldeki hafif ve lokalize iletim gecikmesini tespit etmede yeterlidir. İletim hızı normal olan distal segmentin hafifletici etkisinin ortadan kalkmasıyla duyarlılık %92,4’e yükselmiştir.
