EMG/NCS Testing

Discover the Root Cause of Your Radiating Pain, Radiculopathy, Sciatica, Pinched Nerves, and More…

If you have radiating symptoms in your arms, hands, legs, or feet such as numbness, tingling, burning, or pins and needles, you could be suffering from a nerve impingement. It is very important that the root cause of the nerve impingement be discovered.

For example, the sciatic nerve travels from the lower spine, all the way to the back of your legs, and even supplies the nerves to different parts of the feet. While you may experience symptoms in your legs or feet, the problem could be coming from higher up the nerve pathway.

This is where EMG / NCS testing comes into play. With specific testing of the nerve impulse along the pathway, we can discover where the true impingement is, and then prescribe the correct treatment plan that will relieve the compression and improve the health of the affected area.

What is an EMG/NCS Test?

NCS stands for Nerve Conduction Studies and EMG for Electromyography. The test has two parts. Nerve conduction studies (NCS) are used to measure the health of your nerves. A mild impulse is administered to the skin directly overlying the nerve.

The response is measured by the second set of electrodes applied to the surface of the skin. An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerves control the muscles in the body by electrical signals (impulses), and these impulses make the muscles react in specific ways. Nerve and muscle disorders cause the muscles to react in abnormal ways.

Measuring the electrical activity in muscles & nerves can help find diseases that damage muscle tissue (such as myopathy and muscular dystrophy) or nerves (such as amyotrophic lateral sclerosis or peripheral neuropathies). EMG and nerve conduction studies must be done together to give more complete information.

Do you suffer from any of the following?

  • Back Pain
  • Neck Pain
  • Numbness or tingling in the hands
  • Numbness or tingling in the feet
  • Burning sensation in hands or feet
  • Weakness in the legs
  • Weakness in the arms and hands
  • Sensation of pins and needles
  • Diabetes
  • Neuropathy

If you answered ‘YES’ to any of the above, then you might be a candidate for EMG/NCS Testing and you can ask your doctor or Physical Therapist if this test is appropriate for you.

Thank you for your kind and professional care. Your wonderful staff is dedicated to helping patients feel stronger and better! Thanks again.

How to prepare for this test:

  • Do not use any body or hand lotion for the day of the test.
  • Let us know if you have a pacemaker or defibrillator.
  • Make sure that you know the kind of medications you are taking.
  • Let us know if you are taking aspirin.

The results of the EMG/NCS testing can be very valuable for your Doctor & Physical Therapist to determine various conditions that can affect your nerves and muscles and to manage your care more effectively.
