EMG
Stack #33938
Question | Answer |
---|---|
fibrillation potentials | spontaneous depolarization from single ms fiber, as in peripheral nerve lesions |
positive sharp waves | denervated ms at rest or ms disease (MD, polymyositis) |
fasciculations | spontaneous potentials seen with degenerationi of AHC, nerve root compression, ms spasms/cramps |
neurapraxia | compression of nerve, increased latencies across compressed area |
axonotmesis | neural tube intact, axonal damage w/ wallerian degeneration distal to lesion |
neurotmesis | total loss of axonal ftn, no conduction below lesion |
