This makes an electrical current strong enough to fully stimulate the nerve.Ī computer records responses as nerves are tested. These electrodes act as sensors to pick up any electrical signal that goes by them.Īn electrical stimulator is then placed on the skin near the electrodes. Electrodes are placed on the skin over the nerve being tested. The patient will lie on an exam table (very young children can sit on a parents’ lap). Nerve EMG study: This looks at electrical activity in muscles at rest and when they are moved by choice (if able) to look for certain problems in muscles or nerves.Nerve conduction study (NCS): This tests the speed and amount of electrical activity a nerve can send.This test is helpful to find out if the way a person’s nerves send electrical impulses is normal and if their muscles are normal. The EMG / electromyogram is a test of the electrical activity in nerves and muscles.
