How can a nerve conduction velocity test help in the diagnosis of carpal tunnel syndrome?

ANSWER

This test provides some of the strongest evidence of carpal tunnel syndrome. It measures how fast an electric signal can travel along a nerve or from the nerve to a muscle.

The doctor places a small electrode on your skin near your elbow. It sends a mild electrical current down your median nerve. The more time it takes for the current to travel from your elbow to your fingers, the more damage to your median nerve.
