What is an EMG?
An EMG (Electromyography test) is a nerve conduction study, typically done on the upper and/or lower extremities. The study is used to determine if a patient has nerve or muscle damage. Small electrodes are placed on the skin and a small electric charge is sent through them to determine the rate at which the nerves are firing. Next, an acupuncture-type pin is inserted into muscle tissue to measure the electrical activity inside the muscles. The entire test typically takes 20-30 minutes and is performed in our office.
Who gets an EMG?
EMGs are performed on patients who potentially have nerve and/or muscle damage. If you have experienced numbness, tingling, and/or muscle weakness; or if your doctor has told you have radiculopathies, muscular dystrophy, or nerve disorders such as carpal tunnel, you may want to ask your primary doctor about having an EMG done.
