What is Electrodiagnostic Medicine?An electrodiagnostic exam uses sensors to check the electrical activity of muscles and nerves in order to determine if they have been damaged. Electrodiagnostic medicine specialists are the technicians that perform these exams and the physicians who interpret the results to determine which treatments are necessary. An electrodiagnostic exam can tell you how well the nerves and muscles of the body are functioning or connected. Nerves work by conducting electrical impulses, and muscles are controlled by electrical charges from nerves. Certain symptoms, injuries, or illnesses can indicate a problem with the function of this electrical system within the body. A patient may be referred for an electrodiagnostic exam for conditions such as:
- Carpal tunnel syndrome
- Limb trauma, such as a very deep cut that may have injured the nerves
- Amyotrophic lateral sclerosis, or Lou Gehrig's disease, which can destroy nerve cells
- Unexplained numbness, pain, or weakness
