This is an evidence-based review of electrodiagnostic (EDX) testing of patients with suspected lumbosacral radiculopathy to determine its utility in diagnosis and prognosis. Literature searches were performed to identify articles applying EDX techniques to patients with suspected lumbosacral radiculopathy. From the 355 articles initially discovered, 119 articles describing nerve conduction studies, electromyography (EMG), or evoked potentials in adequate detail were reviewed further. Fifty-three studies met inclusion criteria and were graded using predetermined criteria for classification of evidence for diagnostic studies. Two class II, 7 class III, and 34 class IV studies described the diagnostic use of EDX. One class II and three class III articles described H-reflexes with acceptable statistical significance for use in the diagnosis and confirmation of suspected S1 lumbosacral radiculopathy. Two class II and two class III studies demonstrated a range of sensitivities for use of muscle paraspinal mapping. Two class II studies demonstrated the utility of peripheral myotomal limb electromyography in radiculopathies.
这是一篇关于腰骶神经根病疑似患者电诊断（EDX）检测的循证综述，旨在确定其在诊断和预后中的作用。通过文献检索，确定了应用 EDX 技术对腰骶神经根病疑似患者进行研究的文章。在最初发现的 355 篇文章中，进一步详细审查了描述神经传导研究、肌电图（EMG）或诱发电位的 119 篇文章。53 项研究符合纳入标准，并使用诊断研究证据分类的预定标准进行了分级。两项 II 级、7 项 III 级和 34 项 IV 级研究描述了 EDX 的诊断用途。一篇 II 级和三篇 III 级文章描述了 H 反射，其在诊断和确认疑似 S1 腰骶神经根病方面具有可接受的统计学意义。两项 II 级和两项 III 级研究显示了肌肉旁脊柱肌映射的使用的一系列敏感性。两项 II 级研究证明了外周肌节肢体肌电图在神经根病中的应用价值。
