Symptoms That May Need NCV/EMG
NCV and EMG are most useful when symptoms suggest nerve, root, plexus, muscle, or neuromuscular junction involvement.
- Tingling, numbness, burning feet, or electric shock-like pain
- Hand numbness, suspected carpal tunnel syndrome, or ulnar neuropathy
- Neck or back pain radiating into arm or leg with weakness
- Unexplained muscle wasting, twitching, foot drop, or hand weakness
