Cortical, cervical and lumbar somatosensory evoked potentials were recorded following median and tibial nerve stimulation in patients with traumatic paraplegia and quadriplegia. The isolated cord was able to produce normal potentials even during spinal shock if the vertical extent of the lesion did not involve the generator mechanisms. The cervical potentials showed subtle changes in paraplegia at Th5 levels and below. In high cervical lesions the early cervical potentials may still be present but the later potentials were absent or, in partial lesions, delayed.
在创伤性截瘫和四肢瘫患者中,分别刺激正中神经和胫神经后记录皮质、颈段和腰段体感诱发电位。如果损伤的垂直范围未累及电位产生机制,即使在脊髓休克期间,离断的脊髓仍能产生正常电位。胸5及以下水平的截瘫患者,颈段电位有细微变化。在高位颈髓损伤中,早期颈段电位可能仍存在,但后期电位消失,或在部分损伤时延迟出现。
