What is neuropraxia?

Neuropraxia is best defined as an interruption in conduction due to compression. This condition represents the mildest form of peripheral nerve injury, often resulting from temporary pressure on the nerve. The mechanism behind neuropraxia typically involves a blockage of nerve impulses, which can happen due to factors such as physical compression, stretching, or an injury that does not sever the nerve.

This form of nerve injury is characterized by a rapid recovery, generally within hours to weeks, as the structural integrity of the nerve remains intact, and only the conduction of impulses is affected. Understanding this process is crucial for athletic trainers as they assess and manage conditions associated with nerve injuries.

The other answers suggest conditions or outcomes that do not accurately define neuropraxia. A chronic nerve problem implies a long-term issue, which is not the case with neuropraxia as it usually resolves quickly. A type of nerve paralysis could refer to more severe nerve injuries that involve denervation or damage beyond mere conduction disturbances. An increase in nerve sensation would indicate a different condition, possibly related to nerve regeneration or hyperesthesia, rather than the temporary loss of function characteristic of neuropraxia.
