    What Is EMG?

    Electromyography (EMG) is a diagnostic tool used by doctors to diagnose muscle problems. It measures electrical activity in muscles.

    EMG is an important test for diagnosing neuromuscular disorders. Doctors use EMG to measure how well nerves conduct impulses through muscles.


    What does it measure?

    EMG measures the electrical activity of muscles. This helps doctors determine whether there is damage to the nerve cells that control muscles.


    How does it work?

    An EMG machine uses electrodes to measure electrical activity in muscles. Doctors use an EMG machine to help them identify potential sources of pain and weakness in patients who present with these symptoms. They also use EMGs to monitor the progress of rehabilitation after surgery.


    When should I use it?

    If you have any questions about your body, talk to your doctor. However, if you think you might have a problem with your back, neck, shoulder, arm, leg, foot, or hand, ask your doctor to perform an EMG test.


    What are some common uses?

    Doctors use EMG testing to help them determine whether there is a problem with nerves, muscles, tendons, ligaments, joints, bones, or other soft tissues. They also use EMG to check for nerve damage caused by injury or disease.


    What are some other uses?

    EMG is also used to test for certain diseases such as myasthenia gravis, polymyositis, and amyotrophic lateral sclerosis. In addition, EMG is used to evaluate patients who have had surgery to repair damaged nerves.
