Abstract

Objective: Our aim was to assess and compare the diagnostic accuracy of the carpal tunnel syndrome relief maneuver (CTS-RM) and the Flick sign for the diagnosis of carpal tunnel syndrome (CTS) in female patients. Materials and Methods: This is a diagnostic test study with blind comparison to a reference criterion. A total of 87 consecutive female patients with typical symptoms for CTS referred for electrophysiological examination were included in the study. Normal limits of nerve conduction were obtained from 50 healthy female subjects. After the electrodiagnostic assessment clinical evaluation was performed by a physician and it included testing of all patients for the CTS-RM and Flick sign. The diagnostic accuracy was evaluated for each test alone and in combination and sensitivity was correlated with the electrophysiological severity of CTS. Main outcome measures included the estimates of sensitivity, specificity, positive and negative likelihood ratios (PLR, NLR). Results: After electrophysiological assessment, 58 patients (pre-test probability, 67%) have been diagnosed as CTS. The sensitivity and specificity estimates were %81,86 for the CTS-RM and %69, 79 for the Flick maneuver. Combining a positive CTS-RM and Flick sign improved the specificity to 93%. The PLRs of the CTS-RM and Flick sign were 3.3 and 5.9 and the NLRs were 0.39 and 0.22 respectively. Combining a positive CTS-RM and Flick sign had the PLR of 9.5 and the NLR of 0.37. When evaluating the subjects with CTS, the CTS-RM detected significantly more subjects compared to the Flick sign. Conclusions: Our study reveals that the accuracy of Flick sign is low in the diagnosis of CTS. While the CTS-RM alone is helpful in confirming the diagnosis in patients with typical symptoms, combination with the Flick sign further improves its predictive accuracy.

Özet

Amaç: Amacımız kadın hastalarda karpal tünel sendromu (KTS) tanısında, rahatlatıcı manevra (KTS-RM) ve Flick belirtisinin tanısal değerini ortaya koymaktı. Yöntem ve Gereçler: Bu araştırma diyagnostik bir çalışma niteliğindedir. Tipik KTS semptomları olan ve elektrofizyolojik inceleme için sevk edilen 87 ardışık kadın hasta çalışmaya dahil edildi. Normal sinir iletim değerleri için 50 sağlıklı kadında ölçüm yapıldı. Elektrodiyagnostik incelemeyi takiben aynı hekim tarafından tüm hastalara KTS-RM ve Flick belirtisini içerecek şekilde klinik muayene yapıldı. Testlerin tek başına ve kombine olarak tanısal doğrulukları değerlendirildi. Testlerin duyarlılığı ile elektrofizyolojik KTS şiddeti arasında ilişki düzeyine bakıldı. Ana sonuç parametreleri olarak duyarlılık, özgüllük, pozitif ve negatif olabilirlik oranları (PLR, NLR) kullanıldı. Bulgular: Elektrofizyolojik değerlendirme sonucunda 58 hastada KTS tanısı konuldu (ön-olasılık, %67). KTS-RM ve Flick manevraları için duyarlılık ve özgüllük oranları sırasıyla %81-86 ve %69-79 olarak bulundu. KTS-RM ve Flick belirtisinin aynı anda pozitif olması durumunda, özgüllük oranının %93'e yükseldiği görüldü. KTS-RM ve Flick manevraları için PLR oranları 3.3 ve 5.9, NLR oranları ise .39 ve .22 olarak bulundu. KTS-RM ve Flick belirtisinin aynı anda pozitif olması durumunda, PLR oranı 9.5, NLR oranı 0.37 olarak hesaplandı. KTS tanısı konulan denekler değerlendirildiğinde, KTS-RM'nın Flick manevrasına göre anlamlı oranda daha fazla KTS saptayabildiği görüldü. Elektrodiyagnostik açıdan hastalığın şiddeti arttıkça manevraların duyarlılığının artma eğiliminde olduğu görüldü. Sonuç: Bu çalışma Flick belirtisinin KTS tanısını koymada yetersiz olduğunu göstermektedir. KTS-RM, tipik semptomları olan hastalarda KTS tanısını doğrulamak için tek başına yeterlidir. Flick belirtisi ile beraber ele alındığında doğrulama gücü daha da artmaktadır.
