Carpal tunnel syndrome (CTS) is the most common nerve entrapment. Electrodiagnostic (EDX) studies are a valid and reliable means of confirming the diagnosis. This monograph addresses the various EDX techniques used to evaluate the median nerve at the wrist. It also demonstrates the limitations of EDX studies with a focus on the sensitivity and specificity of EDX testing for CTS. The need to use reference values for populations such as diabetics and active workers, where normative values differ from conventional cutoffs used to confirm suspected CTS, is presented. The value of needle electromyography (EMG) is examined.
腕管综合征（CTS）是最常见的神经卡压症。电诊断（EDX）研究是一种有效的、可靠的确诊手段。本专题介绍了用于评估腕部正中神经的各种 EDX 技术。同时，还重点介绍了 EDX 检查对 CTS 的敏感性和特异性，说明了 EDX 研究的局限性。本专题还介绍了针对糖尿病患者和活跃劳动者等人群使用参考值的必要性，因为这些人群的正常值与用于确诊可疑 CTS 的传统截止值不同。本专题还探讨了针极肌电图（EMG）的价值。
