EMG/NCS Tests, or Electromyography and Nerve Conduction Studies, are tests that measure nerve and muscle function. A physician will typically order this test for patients who have pain, weakness, numbness, or tingling in their arms, legs, head, neck or spine.
Some of the most common medical conditions that would require an EMG/NCS Test include:
- Carpal Tunnel
- Tarsal Tunnel
- Low back and neck pain
- Diabetic or Thyroid conditions
- Muscular Dystrophy
EMG/NCS Frequently Asked Questions
Who will perform your test?
Dr. David Boyce, PT, EdD, ECS, OCS, is an Associate Professor of Physical Therapy at Bellarmine University and co-owner of ProRehab Physical Therapy. He is Board Certified in Clinical Electromyography and has been practicing EMG/NCS for over 20 years.
How is the test performed?
During the nerve conduction (NCS) portion of the exam electrodes are placed on different nerve or muscle sites of the limbs (hands, feet, arms). A small electrical stimulus is applied to the skin that is recorded from the electrodes. During the EMG portion of the exam a very fine wire is placed into the muscle that records the electrical activity of that muscle. A patient typically experiences very minimal, if any, discomfort during the EMG/NCS test. We always make the test as comfortable as possible for patients.
How long does the test take?
In most cases the test is 30-45 minutes. More involved testing can take up to 45-60 minutes.
Who will receive the results of my test?
We will make sure that your doctor receives the results no later than 24 hours following the test. In many cases the results can be faxed immediately after the completion of your test.
What type of information does an EMG/NCS Test provide to my doctor?
The test results assist your doctor in correctly diagnosing your condition and also provides valuable information on your neurological and musculoskeletal system. In addition, it may assist in the management of your condition.
What should I wear?
No special clothing is required; come as you are! If you prefer not to wear a gown during the testing you may want to wear shorts and a tank top.
What should I NOT wear?
Please do not apply any lotions, creams or Vaseline to your skin prior to test. This makes the nerve conduction portion of the exam difficult to perform.
Will insurance cover the cost of my test?
In most cases yes! However, some insurances only cover a portion of the exam. You may also be responsible for a co-pay if your insurance calls for one.
If you have additional questions, please do not hesitate to give the Highlands clinic a call.
