What Are Nerve Conduction Studies?

Nerve conduction studies measure how fast the nerves send electrical signals and an electromyogram (EMG) measures the electrical activity of the nerves while resting as well as while contracting. Muscles are controlled by the nerves sending electrical signals (otherwise known as impulses). These signals give the muscles direction on which way to move or react and with nerve damage, these impulses may be affected and cause the muscles to work abnormally.
