ELECTROMYOGRAPHY (EMG TEST)

WHAT IS ELECTROMYOGRAPHY?

Electromyography (EMG) is a test that measures the electrical activity of the muscles and nerve cells controlling them. Such nerve cells are called motor neurons and they transmit electrical signals that cause muscles to contract and relax. An EMG translates these signals into graphs or numbers, helping doctors diagnose muscle and nerve disorders.

      WHY IS AN EMG PERFORMED?

      An EMG can help doctors learn the cause of tingling, numbness, muscle weakness, muscle cramps, paralysis, and involuntary muscle twitching. The results of an EMG will help your doctor treat that disorder.

      COMPONENTS OF AN EMG TEST

      An EMG test comprises of two components:

      Nerve conduction study is performed first and involves placing surface electrodes on your skin where you are experiencing symptoms. The electrodes will assess the ability of motor neurons to transmit electrical signals.

      Needle EMG is performed after the nerve conduction study and involves inserting needle electrodes directly into the muscle tissue to assess muscle activity at rest and when they are contracted.

      PREPARING FOR AN EMG

      On the day of the test, bathing is recommended to make sure there are no oils, lotions, creams, or perfume on the skin. Do not apply these items before the test. Before the procedure, you will likely be asked to change into a hospital gown. The neurologist will ask you to lie on an examination table and the two components of the EMG test (Nerve conduction study and Needle EMG) will be performed.

      HOW LONG IS AN EMG TEST?

      The procedure normally takes between 30 and 60 minutes.

          WHAT ARE THE RISKS OF AN EMG TEST?

          An EMG is a low-risk procedure. In rare cases you may experience bruising and discomfort on the areas where needle electrodes were inserted but they can be relieved with OTC painkillers.
