Özet
Amaç: Klinik olarak orta ve şiddetli karpal tünel sendromu (KTS) olan gruplar arasındaki elektrofizyolojik (EMG) farklılıkları değerlendirmek. Hastalar ve Metod: KTS’si olan 226 hastada retrospektif olarak 385 el EMG çalışmaları ile değerlendirildi. Italyan KTS çalışma grubunun modifiye edilen kriterlerine gore klinik tutulumları orta ve şiddetli olarak ikiye ayrıldı. Sinir iletim çalışmaları da yine aynı grubun modifiye edilmiş kriterlerine gore orta ve şiddetli olarak klasifiye edildi. Iğne EMG bulguları da analiz edildi. Bulgular: Klinik ve elektrofizyolojik evreleme arasında iyi koralasyon saptandı (p 0.01). Klinik olarak orta ve şiddetli gruplar arasında nörofizyolojik tutulumun şiddeti arasında önemli fark izlenmedi (p0.07). Bununla birlikte iğne EMG anormalliği (p0.01) ve uzamış median F dalga latansı (p0.01) klinik olarak şiddetli grupta anlamlıydı. Ulnar sinir duyu iletim anormallikleri sadece orta derecede etkilenmiş grupta izlendi. Sonuçlar: Bu sonuçlar göstermektedir ki elektrofizyolojik değerlendirme patolojiyi yansıtan oldukça duyarlı yöntem olup klinik tutulumun şiddetinden bağımsızdır.
Aims: To assess the electromyographic (EMG) differences between groups with clinically mild and severe carpal tunnel syndrome (CTS) Patients and Methods: The charts of 226 CTS patients were retrospectively reviewed and a total of 385 hands that underwent EMG studies were identified. These hands were assigned to mild and severe groups according to the severity of the clinical involvement, as defined by the modified criteria of the Italian CTS study group. Nerve conduction studies in these hands were also classified as mild and severe according to the modified criteria of the same group. Needle EMG findings were also analysed. Results: A good correlation between the clinical and electrophysiological staging of the CTS was demonstrated (p<0.01). The severity of the neurophysiological involvement showed no significant change between the clinically mild and severely affected groups (p0.07). However, needle EMG abnormalities (p<0.01) and prolonged median nerve F-wave latencies (p<0.01) were more commonly encountered among the hands showing a severe clinical involvement. Ulnar sensory nerve conduction abnormalities were only observed in the mildly affected group. Conclusion: These results indicate that the electrophysiological investigation, being a highly sensitive procedure, reflects the pathology, independent of the severity of the clinical involvement.
