What is EMG?

What is Electromyography (EMG)?

The study is composed of a nerve conduction study (NCS) and electromyography (EMG), which are performed to measure your muscle and nerve function. A mild electrical current will be applied on your skin and will cause the appropriate muscle to contract which we will measure. Dr. Lopez will perform the EMG study inserting a small pin electrode into the skin and muscles to measure the electrical activity while you rest and contract your muscles.

Before your test

The morning of your test please shower or bathe but do not apply lotion, oils or powder to your arms and legs, since these products may interfere with adherence of the pads used to perform your test. Deodorant is permitted.

Why should I request Dr. Lopez for my EMG?

Dr. Lopez is the only physician in Eastern North Carolina fellowship trained in both neuromuscular disease and electromyography from the Cleveland Clinic, ranked repeatedly as one of the top neurology hospitals by the U.S. News & World Report. She is board certified in both neurology and electromyography (EMG). This specialized training equips Dr. Lopez with the knowledge and expertise to consider appropriate differential diagnoses to plan and perform electrodiagnostic examinations. This expertise is used to establish the correct diagnosis, determine the severity of the problem, prognoses, and assist in the proper management of the problem.

When should I see Dr. Lopez for EMG testing?

Some common problems for which EMG testing can be especially helpful include complaints of pain, weakness, numbness, tingling, carpal tunnel syndrome, ulnar palsy, Lou Gehrig's disease, muscle diseases, muscular dystrophy, foot drop, diabetic and other neuropathies, and radiculopathy due to pinched nerves in the cervical and lumbar spine.
