Understanding an EMG Test

An electromyogram (EMG) gauges the electrical activity of your muscles while resting and also during contractions. This type of nerve conduction study measures the speed with which the nerves transmit electrical signals. The benefits of the test include finding diseases that damage muscle tissue, nerves or the areas between muscles and nerves. They also help determine the cause of muscle twitching, paralysis or weakness.

What to Expect

You should expect the EMG test to last 30 to 60 minutes. It may be performed in your doctor’s office, clinic or hospital. Electrodes will be placed on your skin, so avoid oils, lotions, creams and sprays before the test. You will be seated in a reclining chair or lie on a bed to ensure your muscles are completed relaxed.
•    A needle electrode is inserted into a muscle to record the muscle at rest and during contraction.
•    The electrode may be moved to a different muscle or placed in different areas of the same muscle.
•    The electrical activity in the muscle is monitored and recorded.
•    Your doctor may discuss test results with you immediately following the test.
After the test, you may experience slight tingling or soreness in your muscles. This may last for up to two days. EMGs are very safe tests, although you may experience some swelling or bruising at the needle sites. Call Lakeside Neurocare Limited at 920-223-5580 to learn more about EMG tests.
