Electromyography (EMG) Testing

What is EMG/NCV Nerve Testing?

Physiatrists utilize EMG testing in-office, which is a diagnostic procedure that is useful in determining whether suspected muscle groups or nerves have been injured or related to a specific disease process. It measures the electrical activity of your nerves and muscles.

The test consists of two parts: nerve conduction study and needle electrode examination. EMGs can help determine the cause of muscle weakness, paralysis, spasms, paresthesias, numbness/tingling, as well as pain in the arms, legs, hands, feet and face.

EMGs can be used to diagnose carpal tunnel, tarsal tunnel, neuropathies, cervical and lumbar pinched nerves, tingling or numbness in the arms or legs, and other neurological conditions.
