An Electromyography (EMG) test measures the electrical activity in your muscles to assess the health of the muscle tissue and the nerves that control them. Small needle electrodes are inserted into the muscle, and the electrical signals produced by your muscle fibers are recorded.
EMG testing is essential for diagnosing a variety of conditions that affect the nervous system and muscles. If you’re experiencing symptoms like muscle weakness, numbness, tingling, or pain, an EMG test can help identify the underlying cause. The procedure is minimally invasive and typically performed in a clinical setting, with results that can help guide your treatment decisions.
During the test, small needle electrodes will be inserted into your muscle tissue. The needle will record electrical activity as your muscle contracts. You may be asked to relax or move certain muscles during the test.
The procedure typically lasts around 30 to 60 minutes, depending on how many muscles are being tested.
