Electromyogram (EMG)

  • What is Electromyogram (EMG)?

    An electromyography (EMG) is a technique used to evaluate the function of nerves and muscles by recording the electrical activity produced by the skeletal muscles. It is an important test used to diagnose neuromuscular disorders. It is often used to evaluate disorders of the peripheral nervous system.

    Electromyography involves the insertion of a pin electrode (tiny needle) through the skin into the muscle tissue, and the electrical activity of the muscle is then recorded on a computer. The results allow the neurologist to diagnose any abnormal muscle or nerve activity. This test helps to differentiate between nerve root and muscle disease.

  • An electromyography is commonly performed if an examination suggests impaired muscle strength. Results of an electromyogram allow your doctor to determine if your muscle weakness is due to an injury of a nerve attached to the muscle, or if the weakness is caused by an underlying neurological disorder.

    Your doctor will request an electromyography testing to be done if your diagnosis suggests peripheral nervous system disorders including carpal tunnel syndrome, peripheral neuropathy, diabetic neuropathy, cervical radiculopathy, lumbosacral radiculopathy, sciatica, plexopathy, or nerve injury from trauma or fractures.
