Localised loss of conduction of a nerve, without anatomical disruption, and potentially reversible.
Damage to a nerve from compression or overstretching. There is no disruption to the nerve. Symptoms include pain, tingling and numbness in the distribution of the nerve. These usually resolve spontaneously.
The first level of nerve injury. The large motor fibers are predominately affected and anatomic continuity of the nerve is preserved. The prognosis for recovery is excellent and usually complete within a few days to weeks.
