PURPOSE
To determine whether there is a correlation between the cross-sectional area (CSA) of the median nerve, as measured using ultrasound, and the distal motor and/or sensory latencies as measured on nerve conduction studies.
METHODS
Patients with clinical signs and symptoms of carpal tunnel syndrome were prospectively enrolled in this study. Subjects underwent ultrasound measurement of the CSA of the median nerve at the carpal tunnel inlet by a fellowship-trained hand surgeon, followed by nerve conduction studies (NCS) by a certified electrodiagnostic technician who was blinded to the results of the ultrasound examination. Pearson correlations were performed to compare CSA and NCS.
RESULTS
Pearson correlation was r = 0.57 between CSA and distal motor latency and r = 0.47 between CSA and distal sensory latency. Correlation was r = 0.81 between distal motor latency and distal sensory latency.
CONCLUSIONS
There is a correlation between CSA of the median nerve and NCS. Further research is necessary to determine which test correlates better with patient symptoms and function.
TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.
目的
确定使用超声测量的正中神经横截面积（CSA）与神经传导研究中测量的远端运动和/或感觉潜伏期之间是否存在相关性。
方法
前瞻性纳入有腕管综合征临床体征和症状的患者。由接受过专项培训的手外科医生对受试者进行腕管入口处正中神经CSA的超声测量，随后由一名对超声检查结果不知情的认证电诊断技术人员进行神经传导研究（NCS）。采用Pearson相关性分析比较CSA和NCS。
结果
CSA与远端运动潜伏期之间的Pearson相关系数r = 0.57，CSA与远端感觉潜伏期之间的r = 0.47。远端运动潜伏期与远端感觉潜伏期之间的相关系数r = 0.81。
结论
正中神经CSA与NCS之间存在相关性。需要进一步研究以确定哪种检查与患者症状和功能的相关性更好。
研究类型/证据水平：诊断性研究II级。
