EMG & NCV (Electromyogram & Nerve Conduction Velocity) Studies

If your physician suspects that your condition is a result of decreased nerve function, he/she may order an EMG and/or NCV to examine the integrity and functionality of your nerves.  After the exam, a report is generated and sent to your physician who will go over the results with your at your next office visit.

​

Before Your Test:

​

• Please arrive at least 15 minutes prior to your appointment time. The entire test will last approximately 45-60 minutes.

​

• Please confirm your appointment time and location.

​

• Loose fitting clothing is best, however, you may be asked to wear a gown depending on which nerves are being tested.

​

• We ask that you refrain from applying lotions, oils and/or moisturizers to your skin the day of your EMG study. Otherwise, these items will need to be removed before your study begins.

​

• There are no lasting side effects after the EMG test. There may be mild soreness where the electrode is placed, similar to a tiny prick. However, the sensation goes away quickly. You may apply ice to any sore spots when you get home. Most patients tolerate this very well.

​

• Please inform us if you are taking any blood thinners, such as Coumadin, aspirin, or Plavix, as mild bruising and bleeding may occur.

​

• Please inform us if you have any electrical implants, such as a pacemaker or defibrillator, as this equipment may interfere with the EMG study.

 

 

You have been scheduled for a comprehensive neurodiagnostic evaluation by your healthcare provider. The test should take approximately 60 minutes. A single needle electrode is used during the EMG portion of the test. This needle is the same gauge as an acupuncture needle. During the NCV portion of the test a slight electric impulse is sent through your nerve. This may feel similar to a TENS unit. Generally speaking patients report a slight discomfort during the procedure. A common patient response is “it is not painful, it just feels strange”.
