Electrodiagnosis (EDx) Testing: Electromyography and nerve conduction studies
Electrodiagnosis describes a type of diagnostic test that obtain information about the function of the body by measuring either the electrical activity in the body or the response the body has to an electrical stimulus.
Thrive Health Systems offers electrodiagnostic testing to look at the function of the nerves in the body. The goal of this testing is to determine if there is a problem with a nerve, like it being entrapped; and if so, to find out where that problem is and how bad that problem is.
This test also looks for evidence that a disease process may be affecting many nerves or many muscles. Dr. Karl Robinson, DC, NP has been trained extensively in using electrodiagnostic testing to look at conditions of the peripheral nervous system and neuromuscular system, including nerve conduction studies (NCS), needle electromyography, and evoked potentials (EP).
The NCS (nerve conduction study) part of the exam involves passing brief electrical impulses through nerves and measuring how those nerves respond. Essentially, this procedure looks at the function of the nerves. This part of the test is non-invasive, but it is often considered to be the least comfortable. Most people will say that this part is "uncomfortable but not painful." The NCS does, however, give us very useful information about the function of the nerves, as well as diseases and entrapments of nerves.
Electromyography (EMG) is another form of Electrodiagnosis. It is a diagnostic technique to used evaluate the electrical activity within your muscles.
Because your muscles are controlled by your nerves, the data your doctor gets from an EMG includes information on both the nerves and the muscles, as well as the spinal cord & disorders of the junction between muscles and nerves.
This part of the exam involves a very thin needle that is placed into a muscle to evaluate the electrical activity within that muscle. In this case, the needle acts something like a very sensitive antenna, receiving very subtitle information that your doctor may use to evaluate your neuromuscular system. This part generally doesn't take that long and usually involves between 5 & 15 muscles.
Dr. Robinson is a chiropractic neurologist and a family nurse practitioner with experience in performing and interpreting thousands of electrodiagnostic tests. He has also been board certified with the American Board of Electrodiagnostic Specialties since 2009.
As a member of the Thrive Health Systems team, he is able to provide his expertise in this test when clinically indicated. Dr. Robinson strongly believes in making every effort to reduce any inherent discomfort of this type of test, while not sacrificing the quality of the data obtained.
