Persons with back, neck, and limb symptoms constitute a major referral population to specialists in electrodiagnostic (EDX) medicine. The evaluation of these patients involves consideration of both the common and less common disorders. The EDX examination with needle electromyography (EMG) is the most important means of testing for radiculopathy. This test has modest sensitivity but high specificity and well complements imaging of the spine. Needle EMG in combination with nerve conduction testing is valuable in excluding entrapment neuropathies and polyneuropathy―conditions that frequently mimic radicular symptoms. In this first of a two‐part review, the optimal EDX evaluation of persons with suspected radiculopathy is presented. In part two, the implications of EDX findings for diagnosis and clinical management of persons with radiculopathy are reviewed.

对疑似腰ac部和颈神经根病患者的评估：电诊断评估及其对治疗和预后的影响（第一部分）。

背部，颈部和四肢症状患者构成了电诊断（EDX）医学专家的主要转诊人群。对这些患者的评估涉及对常见和较不常见疾病的考虑。针状肌电图（EMG）进行的EDX检查是测试神经根病的最重要手段。该测试灵敏度适中，但特异性高，可以很好地补充脊柱成像。针肌电图结合神经传导测试在排除卡住性神经病和多发性神经病（经常模仿放射症状）的情况方面很有价值。在这个由两部分组成的综述中的第一篇中，提出了对可疑神经根病患者的最佳EDX评估。在第二部分中
