Procedure - EMG

If you are experiencing numbness, tingling, weakness, or cramping in your muscles, come to Ogden Clinic for an EMG test in Utah. An EMG test, or electromyography, measures the health of muscles, but also the motor neurons (nerve cells) that control the muscles of the body. The EMG test measures the electrical activity given off during muscle contractions in order to diagnosis different kinds of muscle disorders including:

  • Conditions that affect the nerve root (ex. a herniated disk in the spine)
  • Conditions that affect the brain and/or spinal cord (ex. polio)
  • Conditions that affect nerves outside of the spinal cord (ex. carpal tunnel syndrome)
  • Diseases that affect the connection between muscles and nerves (ex. myasthenia gravis)
  • Disorders like muscular dystrophy

Before having an EMG test at Ogden Clinic, it is important to let your neurologist know if you have a pacemaker or other type of electrical medical device, are a hemophiliac, or are using blood-thinning medications of any kind.

How It Works

Depending on the location and severity of your symptoms, your Ogden Clinic neurologist will use electrode patches or needles to test for electrical activity in the muscles. The electrode patches may send currents through your skin that will cause you to spasm or twinge, but it will be not be painful. The electrode needles may cause some pain and discomfort at the injection site, so let the neurologist know if you need to take a break during the EMG test. Throughout the test, your doctor will ask you to contract and rest your muscles at different times. This will help them analyze whether the activity happens while the muscles are at rest.

After the conclusion of your EMG test, you may notice some slight bruising at the needle injection sights, but these should fade within a few days. If the bruises do not fade let your doctor know immediately.

If you have questions regarding your muscle spasms or numbness in your extremities, contact Ogden Clinic to make an appointment for an EMG test. Our Utah neurologists will help you understand your condition and how to manage your symptoms.
