Study Notes
###Â Nerve Structure
- The outermost layer of a nerve is called the epineurium.
Peripherical Nerve Injury (PNI)
- PNI is defined as an injury to a nerve outside of the central nervous system.
Nerve Injury Types
- Axonotmesis is a type of nerve injury characterized by breakdown of the axon and distal Wallerian degeneration.
Wallerian Degeneration
- Wallerian degeneration is the active process of retrograde degeneration of the distal end of an axon that is a result of a nerve lesion.
Treating Nerve Injuries - Phase 1
- The goal of Phase I in the treatment of nerve injuries with denervation is to prevent further injury and optimize the environment for nerve regeneration.
Contraindications for Neurodynamic Techniques
- Contraindications for manual treatment of nervous release using Neurodynamics techniques include active inflammation, recent fractures, and severe pain.
Nerve Conduction
- Nerve conduction in PNI is affected by axonal damage, myelin sheath damage, and changes in the surrounding tissue.
