Nerve Conduction Studies / EMG
Pathological Processes
Two possible types of injury
1. Axonal
2. Myelin sheath
Myelin Sheath Damage
Causes
Commonly seen in compression
- i.e. CTD, ulna nerve at elbow
- area of focal demyelination
Can progress to a conduction block
- some or all axons simply stop working
- decreases the amplitudes
