EMG Tests for Injured Workers

Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities.

    Electromyography (EMG)

    During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle. The electrical activity picked up by the electrodes is then displayed on an oscilloscope (a monitor that displays electrical activity in the form of waves). An audio-amplifier is used so the activity can be heard. EMG measures the electrical activity of muscle during rest, slight contraction and forceful contraction. Muscle tissue does not normally produce electrical signals during rest. When an electrode is inserted, a brief period of activity can be seen on the oscilloscope, but after that, no signal should be present.

    Before Your EMG Test

    • Your doctor will explain the procedure to you and offer you the opportunity to ask any questions that you might have about the procedure.

    • Generally, fasting is not required before the test. In some cases, cigarettes and caffeinated beverages, such as coffee, tea, and cola may be restricted two to three hours before testing.

    • Notify your doctor of all medications (prescribed and over-the-counter) and herbal supplements that you are taking and if you have a pacemaker.

    • Dress in clothes that permit access to the area to be tested or that are easily removed.

    • Stop using lotions or oils on your skin for a few days before your procedure, or at least stop using them on the day of the exam.
