• Benefits

    EMG/EDX is a valuable tool for determining the extent of nerve damage and guiding treatment decisions. This test provides precise information about the functioning of nerves and muscles, allowing your care team to accurately diagnose and localize nerve-related conditions. 

    EMG/EDX can also help differentiate between various types of nerve disorders, such as compression, entrapment, or neuropathy. It also provides a baseline for monitoring the progress of nerve-related conditions over time.

     

  • Risks

    EMG/EDX is generally a safe procedure with minimal risks. However, there are some potential considerations, including pain or discomfort during electrical stimulation, skin irritation, or allergic reaction to the adhesive used to attach electrodes.

  • What to Expect During

    There are two parts to the test. The two are always performed together. 

    Nerve Conduction Velocity: This test, known as a peripheral entrapment neuropathy, identifies areas of nerve compression in the extremity being tested. To perform nerve conduction, your provider will place a small electrode on the skin over the nerve being evaluated. 

    You will feel a static electric shock sensation, similar to walking on a carpet and touching a metal object. This stimulates the nerve to fire and provides graphic evidence of the overall health of the nerve being tested.

    EMG: In an EMG, or Electromyography, your provider will use a special device called an electromyograph to record and analyze the electrical activity produced by your muscles. A fine, sterile needle electrode is inserted into your muscle, and the needle records the electrical activity of your muscle at rest and during contraction.
