Advantage MRI

Medical Diagnostic Imaging Center located in Hermosa, Chicago, IL

Your nervous system is an incredibly vast and complex feature of your body, sending millions of signals each second to keep your body functioning properly. At times, it is important to measure these signals using an electromyography (EMG), also known as a nerve conduction study. Gregory T. Goldstein, MD, and the team at Advantage MRI in the Hermosa neighborhood of Chicago, Illinois, has extensive experience performing EMGs in an accurate and professional manner. To schedule your appointment, call or book online today.


What is an EMG?

As you are reading this, your body is sending nerve signals throughout your body, helping you to interpret the words in front of you, regulate your heart rate, digest your food, feel the seat underneath you, and help you move your body, no matter how small the movements may be. All of this depends on the proper functioning of your nerves to conduct these message impulses to their proper destination. 

Unfortunately, issues with this system can occur, causing neurological symptoms that can range from mild-to-severe. An EMG is a method to test how well your nerves are conducting the signals that are being sent out. EMGs measure the strength and speed at which these signals are traveling and can serve to diagnose neurological abnormalities.

When is an EMG used?

An EMG may be used if you or your doctor suspect that your nervous system may not be functioning optimally. Since the nervous system is involved in almost all processes in your body, a wide range of indications could lead to an EMG. Some of these include:

  • Numbness or tingling in part of your body
  • Pain in part of your body 
  • Muscle weakness
  • Apparent neurological conditions

Based on the results of the test, your doctor can diagnose a wide range of neurological conditions, including:

  • Spinal conditions such as herniated discs
  • Muscular dystrophy
  • Carpal tunnel syndrome
  • Pinched nerves
  • Multiple sclerosis

Your doctor will determine whether or not you need an EMG based on your symptoms. 

What should I expect at my appointment?

The process for an EMG is rather straightforward and intuitive. The team at Advantage MRI will connect an electrode to your skin in the area of the nerve that is being tested. They will then use another electrode to send a small signal through the affected area, which will then be received by the other electrode. 

This will provide information as to the speed and strength that the signal is received, which can be compared to normal nerve function to determine if any abnormalities exist. The team at Advantage MRI is highly trained and experienced at performing EMGs and will be happy to answer any questions that you may have.
