Electromyography (EMG) studies are useful in the anatomical localization of nerve injuries and, in most cases, isolating lesions to a single nerve root level. Their utility is important in identifying specific nerve-root-level injuries where surgical or interventional procedures may be warranted. In this case report, an individual presented with right upper extremity radicular symptoms consistent with a clinical diagnosis of cervical radiculopathy. EMG studies revealed that the lesion could be more specifically isolated to the T1 nerve root and, furthermore, provided evidence that the abductor pollicis brevis receives predominantly T1 innervation.
肌电图(EMG)研究有助于对神经损伤进行解剖定位,并且在大多数情况下,可以将病变定位到单个神经根水平。在需要手术或介入治疗的特定神经根水平损伤的情况下,其具有重要的应用价值。在本病例报告中,个体表现出右侧上肢神经根症状,与临床诊断的颈椎病相一致。肌电图研究表明,病变可以更具体地定位到 T1 神经根,并且进一步提供了证据表明,拇短展肌主要接受 T1 神经支配。
