OBJECTIVE
Electrodiagnostic testing (electromyography [EMG] and nerve conduction studies [NCS]) may result in some patient discomfort. The justification for such testing should be based on the expectation that the results will affect patient management. This study was conducted to determine how frequently the results of EMG/NCS change the clinical management of the patient.
METHODS
One investigator (MB) spoke to each referring physician after EMG/NCS to determine if any management decisions were altered by the test.
RESULTS
One hundred forty consecutive EMG/NCS records were obtained. Follow-up was available on 100 patients. Of 78 patients with abnormal findings on EMG/NCS, 29 (37%) had a diagnosis different from the referring diagnosis. For 43 of the 78 (55%), the physician reported that additional diagnostic testing was undertaken or treatment plans were altered.
CONCLUSION
EMG/NCS are useful, informative, and diagnostic in the management of various neurologic disorders.
目的
电诊断测试（肌电图[EMG]和神经传导研究[NCS]）可能会给患者带来一些不适。进行此类测试的理由应基于预期结果会影响患者的治疗管理。本研究旨在确定EMG/NCS结果改变患者临床管理的频率。
方法
一名研究人员（MB）在EMG/NCS检查后与每位转诊医生进行沟通，以确定测试是否改变了任何治疗管理决策。
结果
共获得140份连续的EMG/NCS记录。对100名患者进行了随访。在78名EMG/NCS检查结果异常的患者中，29名（37%）的诊断与转诊诊断不同。在这78名患者中的43名（55%）中，医生报告进行了额外的诊断测试或改变了治疗计划。
结论
EMG/NCS在各种神经系统疾病的管理中是有用的、信息丰富的且具有诊断价值。
