<unk>  was first defined 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 caudal to the SCI are depressed (dysreflexia) or absent (areflexia), while those rostral to the SCI remain unaffected. Note that the 'shock' in<unk>  does not refer to circulatory collapse.
