What is an EMG/NCS?

If you have pain, numbness, or tingling in your body your doctor may order an electromyogram (EMG) and Nerve Conduction Studies. An electromyogram (EMG) and Nerve Conduction Study is a diagnostic procedure used to evaluate the electrical activity of muscles and the nerve cells. Nerves cells or motor neurons send electrical signals that make the muscles relax and contract. The EMG test converts the electrical signals into graphs, sounds or numbers that are translated by an EMG trained specialist. Using EMG, doctors can determine symptoms such as muscle weakness or pain. A nerve conduction study is a procedure that measures how fast the nerves can send electrical signals. It is used to determine nerve damage and to localize pinched nerves and abnormal muscle.

What disease do EMG/NCS evaluate for?

This test has a wide array of disease that it can diagnose such as, nerve compression or injury (carpal tunnel syndrome and cubital tunnel syndrome), nerve root injury (sciatica or radiculopathy), and muscle disease and damage (myositis).
