What does a normal nerve conduction test rule out?

NCV tests can measure the speed and strength of nerve signals. Nerve conduction velocity between 50 to 60 meters per second is considered normal. A damaged nerve may send a slower and weaker signal than a healthy one. It is possible to have normal results even if a person has nerve damage.

Do you get EMG results right away?

Your doctor may review the results with you right after the procedure.

Will a nerve conduction test show neuropathy?

Confirming if you have a neuropathy These may include: a nerve conduction test (NCS), where small metal wires called electrodes are placed on your skin that release tiny electric shocks to stimulate your nerves; the speed and strength of the nerve signal is measured.
