Electromyography (EMG) Test
Electromyography (EMG) is a test that assesses the health of the muscles and the nerves controlling the muscles. EMG may help diagnose nerve compression or other injuries such as carpal tunnel syndrome, nerve root injuries such as sciatica, and other problems of the muscles and nerves.
The test is performed by inserting a needle electrode through the skin and into the muscle. The electrical activity of the muscles is detected by the electrode and displayed on an oscilloscope. The activity may also be heard through a speaker. After placement of the electrodes, you may be asked to contract the muscle. The presence, size, and shape of the wave form produced on the oscilloscope provide information about how the muscle responds when the nerves are stimulated.
What to expect DURING AN ELECTROMYOGRAPHY (EMG) TEST:
The EMC test will take approximately 30 minutes to 1 hour. Please refrain from using body lotions or oils on your skin the day of the test. No other preparation is necessary.
There may be some discomfort during the insertion of the electrodes and the area may feel tender and appear bruised for a few days following the test. The EMC test will not incapacitate you nor with anything be injected into your body and it will not affect your work status or ability to drive.
