Electromyography (EMG) & Nerve Conduction Studies (NCS)

Getting a detailed look at underlying pain

Nerve Conduction Studies (NCS) and Electromyography (EMG) are diagnostic tests used to evaluate the electrical signals sent from muscles and nerves to other parts of the body. These tests allow Kayal Pain & Spine Center’s award-winning team to understand how the body is functioning and to detect abnormalities that may be causing you pain or discomfort.

During an EMG, a small pin will be placed into the muscles being evaluated. Once the pin is in place, you’ll be asked to flex or tighten that muscle and the electromyograph will record electrical signals from the muscle as it is being used.

The NCS procedure also records electrical signals, focusing on the sensory and motor nerves. During this test, sensors are placed on the skin and a small electrical pulse is sent to activate the nerves. It’s common for muscles to twitch as the electrical signals are being recorded.

The experts at Kayal Pain & Spine Center will use the results of the EMG and NCS tests to help identify likely causes of specific symptoms. For example, certain conditions will only impact particular nerve groups with severity levels consistent across patients. This allows your surgeon to use the nerve signal results to help determine which diseases or disorders are causing symptoms. As a result, EMG and NCS can be used to diagnose many common conditions, including carpal tunnel, motor neuron disease, radiculopathy and myopathies.


Pre-Op & Aftercare

What to expect before, during and after electromyograph

The electromyograph test takes about 15 to 30 minutes. Preparation is relatively simple. You can continue following your regular routines, including taking most prescription medication. Pacemakers and defibrillators are safe to use as well.

During the procedure, you will remain in your clothes, so be sure to wear clothing that can be removed quickly or allows easy access to the areas of your body being tested. In addition, ensure the area is clean and do not apply any lotions or powders to the skin being tested before the procedure.

After the exam, you should not experience significant side effects. Some patients feel discomfort or soreness for a day or two after the exam. It’s also possible to get a small bruise from the pin test. Regardless, you will be able to carry on with your regular routines without restriction and can drive home after the procedure.



Discover the advantages

EMG and NCS tests provide significant insight into the function of the muscles and nerves within the body, allowing your doctor at Kayal Pain & Spine Center to make accurate diagnoses of many common conditions. While imaging tests like MRI and CT scan are excellent at capturing pictures, the body can only be evaluated as it was the moment the image was taken. Additional function tests, like EMG and NCS, help provide a more holistic view of how the body is operating and what conditions may be causing pain or other symptoms.

Electromyography and nerve conduction studies also allow your Kayal Pain & Spine specialist to diagnose conditions that cause mysterious symptoms, including tingling, numbness and weakened muscles. Finding the source of these symptoms is essential but can’t always be accomplished with other tests.

Kayal Pain & Spine Center’s elite team uses EMG and NCS tests to diagnose the cause of your pain with greater accuracy and to develop strategic treatment plans that are right for your specific condition.
