There are several reasons that you may need an
ELECTROMYOGRAM (EMG)
Let us test the electrical activity of your muscles!
Used to detect abnormal electrical activity,
EMGs can help diagnose a variety of diseases and conditions. An electromyogram (EMG) records the electrical activity in muscles; when muscles are active, they produce a current. This current is usually proportional to the level of muscle activity. This test is usually performed when patients have unexplained muscle weakness, and can distinguish between muscle conditions in which the problem begins in the muscle and muscle weakness due to nerve disorders.
​
The EMG can also be used to detect true weakness, as opposed to weakness from reduced use because of pain or lack of motivation. EMGs can also be used to isolate the level of nerve irritation or injury. It can detect pinched nerves, peripheral nerve damage (damage to the nerves in arms and legs), disc herniation, and much more.
WHAT TO EXPECT
PRIOR TO YOUR EMG​
You should arrive for your EMG with clean, dry skin. Please do not use body lotions, oils, etc; as this interferes with the test and may result in rescheduling and/or repeating the EMG test.
​
THE PROCEDURE
Your skin will be prepared with alcohol wipes to ensure transference. There are two portions to this test:
1) Nerve Conduction Study: Electrodes will be placed on your skin and an electrical impulse is introduced.
2) Electromyography: A small thin needle is inserted just beneath the skin's surface.
​
AFTER THE PROCEDURE
You may experience slight discomfort, but it should not affect your daily activity. The discomfort can be resolved with ice treatment for 10-15 minutes. The results of your EMG test will be prepared and forwarded to your referring or Primary Care Physician within 3-5 working days after your test.
