We attempted to determine if a prognostic value could be associated with preoperative electrodiagnostic testing in patients with carpal tunnel syndrome. Three groups of patients were included in the study of 151 workers whose symptoms were thought to be causally related to their jobs. A clinical diagnosis was made without electrical testing in 26 of the 151 patients. Normal electrical test values were present in 50 of the 125 patients tested, and abnormal values were noted in 75 patients. Pinch, power, and static grasp function were recorded monthly. Similar recovery patterns after operation were seen between the groups and within each group. Return to work time correlated well with measured functional recovery to preoperative levels, but some workers returned to their jobs before they had regained full function. Electrodiagnostic test results did not provide significant data for prediction of functional recovery or re-employment after carpal tunnel release.
我们试图确定术前电诊断测试是否对腕管综合征患者具有预后价值。在一项针对151名工人的研究中纳入了三组患者，这些患者的症状被认为与其工作有因果关系。151名患者中有26名未经电测试即做出了临床诊断。在接受测试的125名患者中，50名电测试值正常，75名患者电测试值异常。每月记录捏力、握力和静态抓握功能。各组之间以及每组内部术后均呈现相似的恢复模式。恢复工作时间与测量的功能恢复到术前水平密切相关，但一些工人在功能未完全恢复之前就返回了工作岗位。电诊断测试结果并未为预测腕管松解术后的功能恢复或再就业提供有意义的数据。
