To examine the association between different patterns of hand symptoms and the presence of delayed nerve conduction in the general population.
We performed a 2-stage screening survey involving a questionnaire on current hand symptoms, and nerve conduction testing in samples of subjects with and without symptoms. Of 648 respondents to the symptom questionnaire, 212 reported hand symptoms. In all, 155 were tested for nerve conduction of sensory and motor median nerve latencies, including 40 who had reported no symptoms. Patterns of hand symptoms were compared with nerve conduction results and associations weighted back to the general population.
The presence of any hand symptoms had only a 40% sensitivity for delayed nerve conduction on latency testing. The presence of typical symptoms of carpal tunnel syndrome had a much lower sensitivity.
In a community setting, the distribution of hand symptoms does not usefully correlate with the presence of delayed nerve conduction in the median nerve.
研究普通人群中不同手部症状模式与神经传导延迟之间的关联。
我们进行了一项两阶段筛查调查，包括一份关于当前手部症状的问卷，以及对有症状和无症状受试者样本进行神经传导测试。在648名症状问卷受访者中，212人报告有手部症状。总共对155人进行了感觉和运动正中神经潜伏期的神经传导测试，其中包括40名报告无症状的人。将手部症状模式与神经传导结果进行比较，并将关联权重回普通人群。
在潜伏期测试中，任何手部症状的存在对神经传导延迟的敏感性仅为40%。腕管综合征典型症状的存在敏感性要低得多。
在社区环境中，手部症状的分布与正中神经传导延迟的存在没有有效关联。
