In the management of spine trauma with radicular symptoms (STRS), EMG/nerve conduction studies (NCS) often have low combined sensitivity and specificity in confirming root injury. The anatomic level of injury may not correspond to the root level. Paraspinal studies are nonlocalizing and can be falsely positive and negative. Unlike MRI and CT imaging, EMG/NCS do not reveal the biological morphology of the lesion. There are no studies that confirm the efficacy of EMG/NCS in the management of STRS. EMG/NCS may be indicated if there is a differential diagnosis between a root and distal neuropathic/myopathic lesion. Otherwise, as shown in this series of cases typically referred for outpatient EMG/NCS testing, there is limited evidence to support the use of often uncomfortable and costly EMG/NCS in STRS.
在伴有神经根症状的脊柱创伤（STRS）管理中，肌电图/神经传导研究（EMG/NCS）在确认神经根损伤方面的联合敏感性和特异性通常较低。损伤的解剖水平可能与神经根水平不对应。椎旁研究无法定位，可能出现假阳性和假阴性结果。与MRI和CT成像不同，EMG/NCS无法显示病变的生物学形态。尚无研究证实EMG/NCS在STRS管理中的有效性。如果需要鉴别神经根病变与远端神经病变/肌病性病变，则可能需要进行EMG/NCS检查。否则，正如这一系列通常转诊进行门诊EMG/NCS检查的病例所示，支持在STRS中使用往往会带来不适且费用高昂的EMG/NCS的证据有限。
