- General information
- Measurement of conduction velocity along a peripheral nerve can test motor, sensory, and reflex pathways
- Timing of electrodiagnostic testing
- EMG changes take 1 to 3 weeks to become recordable in the muscles.
- Nerve conduction abnormalities, however, are present immediately and can be helpful in the immediate determination of the extent of injury.
- Electrodiagnostic studies of peripheral nerves consist of two parts
