OBJECTIVE
Work related electrical accidents are prevalent and can cause persisting symptoms. We used clinical neurophysiological techniques to assess neurosensory function following electrical accidents and correlated test results with the patients' symptoms.
METHODS
We studied 24 patients who reported persisting neurosensory symptoms following a workplace electrical accident. We assessed nerve function using quantitative sensory testing (QST), thermal roller testing, laser evoked potential (LEP), and electroneurography. The patients' results were compared with previously established normative data.
RESULTS
Altogether, 67% of the patients showed at least one neurosensory impairment with a large heterogeneity in test results across patients. At a group level, we observed significant deviations in in QST, LEP, and sensory and motor neurography. Overall, we found a weak correlation between test results and self-reported symptoms.
CONCLUSIONS
In a majority of patients with neurosensory symptoms after a workplace electrical accident, neurosensory testing confirmed the existence of an underlying impairment of the nervous system.
目的
与工作相关的电气事故很常见，且可能导致持续的症状。我们运用临床神经生理学技术评估电气事故后的神经感觉功能，并将测试结果与患者症状相关联。
方法
我们研究了24名报告在工作场所发生电气事故后存在持续神经感觉症状的患者。我们使用定量感觉测试（QST）、热滚轮测试、激光诱发电位（LEP）和神经电图来评估神经功能。将患者的结果与先前建立的标准数据进行比较。
结果
总体而言，67%的患者表现出至少一种神经感觉障碍，患者之间的测试结果存在很大异质性。在组水平上，我们观察到QST、LEP以及感觉和运动神经电图存在显著偏差。总体而言，我们发现测试结果与自我报告的症状之间存在弱相关性。
结论
在大多数工作场所电气事故后出现神经感觉症状的患者中，神经感觉测试证实存在潜在的神经系统损害。
