Screening for the onset of carpal tunnel syndrome (CTS), which is associated with excess ergonomic stresses of the wrist and hand, is a major concern in occupational medicine. CTS questionnaires, physical examinations, and quantitative sensory function determination through neuroselective current perception threshold (CPT) measurements were obtained from the median digital nerves of 16 assembly line workers who were symptomatic with hand pain. Median nerve evaluations by CPT detected sensory abnormalities in 75% of the workers, and abnormalities in 50% of the workers were detected by clinical evaluations (p less than .05, df = 22). CPT abnormalities were characterized as "hypoesthetic" in 25% and hyperesthesic in 42% of the workers. The noninvasive, nonaversive CPT technique provided sensitive and easily obtained quantitative measures. Regular use of this procedure in the occupational setting may assist in preventing the development of advanced CTS for it provides early detection of median nerve abnormalities.
筛查与手腕和手部过度工效学压力相关的腕管综合征（CTS）的发病情况，是职业医学中的一个主要关注点。从16名手部疼痛症状明显的装配线工人的正中指神经获取了CTS问卷、体格检查以及通过神经选择性电流感觉阈值（CPT）测量进行的定量感觉功能测定。通过CPT进行的正中神经评估在75%的工人中检测到感觉异常，而通过临床评估在50%的工人中检测到异常（p小于0.05，自由度=22）。在25%的工人中，CPT异常表现为“感觉减退”，在42%的工人中表现为“感觉过敏”。这种非侵入性、无痛苦的CPT技术提供了敏感且易于获得的定量测量。在职业环境中定期使用该程序可能有助于预防晚期CTS的发展，因为它能早期检测正中神经异常。
