When abnormal muscle cramping or pain reduces your quality of life, diagnostic electromyography (EMG) can pinpoint the root cause of your symptoms. At Maryland Sports, Spine and Musculoskeletal Institute in Pasadena, Maryland, Justin Waltrous, MD, offers on-site EMG testing to determine the cause of your pain so treatment can begin as soon as possible.

Electromyography is a diagnostic testing resource that records the electrical impulses in your muscles. This type of test can also evaluate the functionality of the nerve cells that control your muscle movements.
The test uses small sensors, known as electrodes, that collect the electrical signals and translate the data into graphs or numbers. This information is what Dr. Waltrous uses to understand the results of your testing.
You may need an EMG if you’re experiencing pain or other symptoms that may indicate a muscle or nerve disorder. These symptoms may include:
Testing can determine if you have a disorder or disease that causes your pain, such as a herniated disc, carpal tunnel syndrome (CTS), or a muscle disorder.
An EMG involves two types of testing procedures. In one procedure, Dr. Waltrous places electrodes on the surface of your skin near the area experiencing pain. This delivers a low electrical current, which can cause your muscles to spasm or twitch at times.
Another type of EMG procedure involves the insertion of a slender needle into your muscle tissue. This test allows Dr. Waltrous to assess if you have abnormal electrical activity in your muscle while it’s at rest. It also determines the level of activity during muscle contractions.
In the needle EMG, Dr. Waltrous asks you to contract or relax your muscle during different phases of the test.
Immediately after your EMG, you can expect to go home. There may be some minor bruising in the area of needle insertion that goes away in a few days on its own.
Dr. Waltrous reviews the results of your test and may recommend additional testing procedures for diagnostic purposes. If he’s able to make a diagnosis after the EMG, he can discuss his ideas for treatment with you based on your condition.
If you have unexplained nerve pain that interferes with your ability to stay active, schedule a consultation at Maryland Sports, Spine and Musculoskeletal Institute online or by phone today to learn more about the diagnostic benefits of an EMG.
