<unk>  was first explored by Whytt in 1750 as a loss of sensation accompanied by motor paralysis with initial loss but gradual recovery of reflexes, following a<unk>  cord injury (SCI) – most often a complete transection. Reflexes in the<unk>  cord below the level of injury are depressed (hyporeflexia) or absent (areflexia), while those above the level of the injury remain unaffected. The<unk> ' in<unk>  does not refer to circulatory collapse, and should not be confused with neurogenic<unk> , which is life-threatening. The term<unk> ” was introduced more than 150 years ago in an attempt to distinguish arterial hypotension due to a hemorrhagic source from arterial hypotension due to loss of sympathetic tone resulting from<unk>  cord injury. Whytt, however, may have discussed the same phenomenon a century earlier, although no descriptive term was assigned. __TOC__
