High voltage electrical injury can cause considerable damage to the nervous system including spinal cord, but, thepathophysiology of myelopathy remains to be studied. A 44-year old man with paraparesis after electrical injury wasdiagnosed as electrical injury induced- myelopathy by normal spine MRI and somatosensory evoked potential showingcentral conduction abnormality. It implicates that the presumed mechanism of the myelopathy prefers the electroporationor electroconformational protein denaturation to the joule heating.
