- electricity
What are the 3 categories of injury to the nerve
- Neuropraxia
- Axonotmesis
- Neurotmesis
Define neuropraxia

segmental demyelination of the nerve, signal is slow or blocked at site of compression or traction and its temporary
Define axonotmesis

loss of axonal continuity the connective tissue is still intact, results from prolonged compression or stretch recovery may be incomplete. May have muscle atrophy and sensory loss
Define neurotmesis

complete severance of nerve and connective tissue, resulting from a stabbing, avulsion or rupture. may not recover and may require surgery. Can suffer frommuscle atrophy and sensory loss
What are the 3 phases of management of a nerve injury
- acute
- recovery
- chronic
What is done during the acute phase of nerve injury management
- ROM to minimize adhesions ( limited to specific ranges per protocol)
- Splint to protect tissue
- Patient education
What is done during the recovery phase of nerve injury management
- motor retraining
- desensitization
- discriminative sensory re-education
- patient education
