- Neuropraxia is to nerves as sprain is to ankle
- Lowest level of neural injury (1 level)
- It is a transient conduction block; lasts seconds MAYBE minutes with little to no structural failure
- Affects peripheral axis of nerve
- Repeated injury may result in greater neurological damage such as Axonotmesis and Neurotmesis (severed
Charbonneau et al.
