Diagnosis of carpal tunnel syndrome (CTS) is frequently confirmed by performing nerve conduction studies. Previous studies demonstrated that abnormal nerve conduction study (NCS) is suggestive of CTS among asymptomatic individuals. However, previous studies included individuals with risk factors for the syndrome. A NCS was performed on the median and ulnar nerves in 130 healthy individuals. About 15% of individuals in this study demonstrated electrodiagnostic evidence of carpal tunnels syndrome. Four cases have shown signs of isolated median neuropathy with normal median sensory component. Results indicated that the most widely used method for confirming diagnosis of CTS may have up to 15% of false positives. However, most of those showed changes of minimal CTS. Isolated prolongation of the median motor latency should be investigated further as they are usually classified as moderate to severe CTS and may undergo unnecessary surgeries.
腕管综合征（CTS）的诊断通常通过进行神经传导研究来确诊。先前的研究表明，无症状个体中神经传导研究（NCS）异常提示腕管综合征。然而，先前的研究纳入了具有该综合征危险因素的个体。对130名健康个体的正中神经和尺神经进行了神经传导研究。本研究中约15%的个体显示出腕管综合征的电诊断证据。4例显示孤立性正中神经病变且正中感觉成分正常。结果表明，用于确诊腕管综合征的最常用方法可能有高达15%的假阳性。然而，其中大多数显示为轻度腕管综合征的改变。孤立性正中运动潜伏期延长应进一步研究，因为它们通常被归类为中度至重度腕管综合征，可能会接受不必要的手术。
