Electroneuromyography (ENMG) is the electrophysiological examination of central and peripheral nervous system, neuromuscular transmission and the muscles with electroneuromyography (ENMG) is important in the assessment of neuromuscular disorders.
There are actually two parts to EMG:
- Nerve conduction studyThe nerves are stimulated at different points with small electric shocks, artificially activating them so their function can be measured.
- Needle exam for muscle testingVery fine needles are inserted into several muscles. Each needle has a microscopic electrode that picks up both the normal and abnormal electrical signals given off by a muscle.
What is an EMG test used to diagnose?
- Carpal tunnel syndrome
- Pinched nerve
- Muscle diseases
- Muscular dystrophy
- Myasthenia gravis
