 Electromyography and Nerve Conduction Tests


Electromyography is used to diagnose nerve and muscle dysfunction and spinal cord disease. And Electromyography test and a Nerve Conduction test are often done together.

Electromyography is performed by a doctor called a neurologist who specializes in disorders of the nerves and nervous system. a Nerve Conduction Test is performed by a technologist.

The Electromyography uses a visual and an auditory signal to detect if there is anything abnormal in the system of muscles and nerves in your body.

During a Nerve Conduction test, your nerves are stimulated and the time between when the stimulation occurs and when your nerves respond is displayed, measured and recorded.

The purposes of these tests are:

  • To see if the muscles and nerves in your body are working properly
  • To assess symptoms such as numbness, tingling and weakness

What to Expect During Your Electromyography Test

  • During your Electromyography test the neurologist will insert a small needle into one of your muscles. This is done so that a very small wire electrode can record any changes in electrical activity when you are moving and when you are at rest.
  • You may feel some discomfort.
  • Your test will take approximately…

 What to Expect During Your Nerve Conduction Test
