Electromyography (EMG) Test

This is a test in which very small electrodes are placed into your muscle tissue. It looks at the electrical impulses of your muscle tissue. This test is used to determine whether or not there are involuntary or spontaneous muscle movements. Involuntary or spontaneous means muscle movements that happen by themselves. This may indicate injury or disease of the nerves which supply that muscle.

PREPARATION FOR TEST

No preparation or fasting is necessary. Some stimulants such as caffeine and tobacco may need to be avoided for 2-3 hours before test or as instructed by your caregiver.

NORMAL FINDINGS

No evidence of neuromuscular abnormalities.

Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.

MEANING OF TEST

Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.

OBTAINING THE TEST RESULTS

It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
