Electromyogram (EMG)

  • What is an Electromyogram?

    An electromyography (EMG) evaluates 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 and to evaluate disorders of the peripheral nervous system.

    An EMG involves the insertion of a pin electrode (tiny needle) through the skin into the muscle tissue, which records the electrical activity of the muscle onto a computer. The results allow the neurologist to diagnose any abnormal muscle or nerve activity. This test helps to tell the difference between a nerve root disease and a muscle disease.

  • An EMG is commonly done if an examination shows reduced muscle strength. Results of an EMG will 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 EMG test 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.
