A cross-sectional study of 471 randomly selected employees from 4 industries was performed to assess the prevalence of slowing of sensory conduction of the median nerve at the carpal tunnel as well as the effect of age and sex on slowing. The association between slowed conduction and symptoms of carpal tunnel syndrome (CTS) was also evaluated. Slowing was identified in 17% of the subjects and in 11% of the hands. The prevalence and the severity of slowing increased with increasing age of the subjects. Slowed conduction occurred more often among the women in the study, but this was shown to be an effect of age and not of sex. Slowing occurred six times more often in hands with symptoms of CTS than in those not reporting symptoms.
对从4个行业随机选取的471名员工进行了一项横断面研究，以评估腕管处正中神经感觉传导减慢的患病率以及年龄和性别对传导减慢的影响。还评估了传导减慢与腕管综合征（CTS）症状之间的关联。在17%的受试者和11%的手部中发现了传导减慢。传导减慢的患病率和严重程度随受试者年龄的增加而增加。在该研究中，传导减慢在女性中更常见，但这被证明是年龄的影响而非性别的影响。有CTS症状的手部传导减慢的发生率比未报告症状的手部高6倍。
