Electromyographic studies were performed on 16 patients with intractable low back pain and no antecedent history of malignancy or metastatic disease. In each case, electromyographic evidence of severe segmental denervation limited to the paraspinal muscles innervated by the posterior primary rami was found. Subsequent diagnostic studies in each patient revealed a primary neoplasm or tumor metastasis as the source of pain. Applying current knowledge of neuromuscular physiology, the electromyograph may prove to be a valuable aid to the early detection of remote metastasis to the spine and paraspinal muscle structures.
对16例顽固性下背痛且无恶性肿瘤或转移性疾病既往史的患者进行了肌电图研究。在每例患者中，均发现严重节段性去神经支配的肌电图证据，且仅限于由后支支配的椎旁肌。随后对每位患者的诊断性检查均发现原发性肿瘤或肿瘤转移是疼痛的根源。应用当前的神经肌肉生理学知识，肌电图可能被证明是早期检测脊柱和椎旁肌结构远处转移的有价值辅助手段。
