The most common subtypes of Guillain‐Barré syndrome (GBS) are acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN). In the first days after the onset of weakness, standard nerve conduction studies (NCS) may not distinguish GBS subtypes. Reduced nerve excitability may be an early symptom of nerve dysfunction, which can be determined with the compound muscle action potential (CMAP) scan. The aim of this study was to explore whether early changes in motor nerve excitability in GBS patients are related to various subtypes.

吉兰-巴利综合征急性期运动神经兴奋性的变化

吉兰-巴利综合征 (GBS) 最常见的亚型是急性炎症性脱髓鞘性多发性神经病 (AIDP) 和急性运动轴突神经病 (AMAN)。在出现无力后的最初几天，标准神经传导研究 (NCS) 可能无法区分 GBS 亚型。神经兴奋性降低可能是神经功能障碍的早期症状，可以通过复合肌肉动作电位（CMAP）扫描来确定。本研究的目的是探讨 GBS 患者运动神经兴奋性的早期变化是否与各种亚型有关。
