Temporary loss of reflexes after trauma to the spine is diagnosed as what?

• A. Spinal Ataxia
• B. Spinal Concussion
• C. Spinal Shock
• D. Neurogenic Shock

Answer: (C)

Spinal shock is the transient suppression of reflex activity below the level of spinal injury. In the immediate aftermath of trauma, the spinal cord below the injury loses its normal excitability, producing flaccid paralysis and absence of deep tendon reflexes below the lesion, along with loss of bladder and bowel reflexes. This state is temporary; over hours to weeks, reflexes gradually return and may become exaggerated (spastic) as the shock passes. This distinguishes it from other concepts: spinal concussion implies a brief, milder neurologic disruption that resolves quickly and isn’t defined by a persistent loss of reflexes; spinal ataxia refers to coordination problems rather than a transient loss of reflexes after spinal injury; neurogenic shock is a circulatory issue from loss of sympathetic tone (hypotension, bradycardia) rather than a primarily reflex-based phenomenon, even though reflexes can be reduced early on.
