The phenomenon of delayed neurodegenerative syndromes following lighting and electrical injury has been known since the early 1930s （Critchley, 1934）, but to the present day, the mechanisms involved have been poorly un- derstood. An initial and still plausible theory is that the electrical insult causes damage to the vascular structures feeding the spinal cord via damage to vascular endothelial cells （Farrell and Starr, 1968）.展开更多
