Details of the clinical history were elicited by questionnaire from 8,223 patients with suspected carpal tunnel syndrome and compared with the neurophysiological findings. Distribution of symptoms to the radial part of the hand and nocturnal exacerbation of symptoms showed the strongest individual correlations with positive nerve conduction studies. The regression model derived from the complete questionnaire achieved an overall sensitivity of 79% and specificity of 55% for the diagnosis of carpal tunnel syndrome when compared with the nerve conduction study results as a gold standard. A simple regression model for evaluating the history compares favourably with widely used clinical signs in its ability to predict the findings of nerve conduction studies.
通过问卷调查收集了8223例疑似腕管综合征患者的临床病史细节，并与神经生理学检查结果进行了比较。手部桡侧症状分布和症状夜间加重与神经传导研究阳性显示出最强的个体相关性。与作为金标准的神经传导研究结果相比，从完整问卷得出的回归模型对腕管综合征诊断的总体敏感性为79%，特异性为55%。在预测神经传导研究结果的能力方面，一个用于评估病史的简单回归模型与广泛使用的临床体征相比具有优势。
