Electrodiagnostics, including both nerve conduction studies (NCS) and electromyography (EMG), are studies used to help diagnose nerve and muscle diseases.
NCSs demonstrate how the body’s electrical signals travel through the nerve. We use a small electrical shock placed on the skin that activates the nerve and we record how the nerve is working.
For EMG, we use a small, thin, needle electrode that is placed into muscles to help understand the nerve or muscle issue.
Bring a list of all your medications, and tell your EMG doctor if you are taking any blood thinners, have a pacemaker, or a bleeding disorder.
Bring shorts and/or tank top depending on the area of the body being tested.
Do not use body lotion on the day of your test.
You may go about your regular daily activities (eating, working, driving, exercising, etc) before and after the test. There are no lasting side effects to the tests.
Some tests can take up to 2 hours to complete.
The EMG doctor will discuss your test result with you once the examination is completed. The results will also be sent to your referring doctor.
Dr. Ida Cavaliere has a special interest in electrodiagnostics, including both Nerve Conductions Studies (NCS) and Electromyography (EMG). This aspect of her clinical activities focuses on the diagnosis of focal neuropathies, radiculopathies as well as other neuromuscular conditions. Click here to find out more about Dr. Cavaliere.
