背景。目前，腕管综合征（CTS）诊断的金标准是一个有争议的话题。传统上将神经传导研究（NCS）用作确诊测试，而超声（USG）作为CTS的替代诊断测试已引起了人们的兴趣。现已提出可利用超声测量腕管正中神经横截面积作为CTS确诊的替代方法。

目的：本研究的目的为以经验证结合病史和查体结果的临床诊断工具（CTS-6）为参照，比较超声和电诊断研究在腕管综合征诊断中的敏感性和特异性。

资料与方法。本横断面研究纳入40例（20例病例和20例对照）成年和青少年男女患者，主诉上肢疼痛和感觉异常。所有患者均采用CTS-6临床诊断工具进行评估。CTS评分≥12分的患者考虑为腕管综合症阳性诊断（病例）（主要组）。CTS评分<12分的患者作为对照组。在进行超声和电诊断研究的人员中，将CTS-6和超声检查结果设盲。

结果。我们发现USG的敏感性为90％、特异性为85％、阳性预测值为85.71％、阴性预测值为89.47％。NCS的敏感性为85％、特异性为80％、阳性预测值为80.95％、阴性预测值为84.21％。

结论。采用临床工具CTS-6作为标准参照，USG的敏感性和特异性高于NCS。
