A case of cauda equina claudication with canal stenosis is presented. Neurophysiological studies show reversible changes during symptomatic and asymptomatic phases. The somatosensory evoked potential from the tibial nerve was reduced in amplitude. Central motor conduction time (CMCT) after transcranial magnetic stimulation of the brain was reversibly prolonged in the symptomatic phase. Reversible CMCT changes have not been previously shown. The findings are discussed in the light of the pathophysiology of ischaemic nerve.
本文报道了一例伴有椎管狭窄的马尾神经间歇性跛行病例。神经生理学研究显示，在症状期和无症状期存在可逆性变化。胫神经体感诱发电位的波幅降低。在症状期，经颅磁刺激大脑后的中枢运动传导时间（CMCT）可逆性延长。此前尚未发现CMCT的可逆性变化。根据缺血性神经的病理生理学对这些发现进行了讨论。
