The authors studied five patients with MS and four patients with HTLV-1 associated myelopathy (HAM) to investigate the usefulness of paraspinal motor evoked potentials (MEP) after magnetic stimulation of the motor cortex. In patients with MS, MEP disappeared or onset latencies were delayed below the lesion. In patients with HAM, the onset latencies were prolonged bilaterally. Thus, paraspinal MEP are very useful in detecting spinal cord lesions.
作者研究了5例多发性硬化症患者和4例人类嗜T淋巴细胞病毒1型相关性脊髓病（HAM）患者，以探讨磁刺激运动皮层后椎旁肌运动诱发电位（MEP）的效用。在多发性硬化症患者中，MEP消失或在病变水平以下起始潜伏期延迟。在HAM患者中，双侧起始潜伏期延长。因此，椎旁MEP在检测脊髓病变方面非常有用。
