Hodges places electrodes on the surface of your skin near the area experiencing pain. What can I expect during an EMG?Īn EMG involves two types of testing procedures. Testing can determine if you have a disorder or disease that’s responsible for your pain, such as carpal tunnel syndrome (CTS), a herniated disc, or a muscle disorder. You may need an EMG if you’re experiencing pain or other symptoms that can indicate a nerve or muscle disorder. Hodges uses to understand the results of your testing. The test uses small sensors, known as electrodes, that collect the electrical signals and translate the data into graphs or numbers. This type of test can also evaluate the functionality of the nerve cells that control your muscle movements. Electromyography is a diagnostic testing resource that records the electrical impulses in your muscles.
