With nerve conduction studies, you may feel a quick, burning pain, a tingling feeling, and a twitching of the muscle each time the electrical pulse is given. It feels like the kind of tingling you feel when you rub your feet on the carpet and then touch a metal object. The tests make some people anxious.
A nerve conduction study can show if the motor neurons within a muscle are sending strong or weak signals, and it also assesses signal speed. Doctors may order an EMG in patients who have nerve pain, muscle spasms or weakness, tingling and numbness. Some conditions that may cause signs of nerve damage include spinal disorders such as herniated discs, peripheral nerve disorders that affect the limbs, and neuromuscular disorders such as muscular dystrophy.
