EMG & Nerve Conduction

Informative Nerve Testing Process

Electrodiagnostic studies at Center for Advanced Pain Management and Rehabilitation, LLC are a way that we can diagnose conditions in your muscles or nerves. These tests help narrow down the causes of your back pain, neck pain, numbness, tingling, and strength loss. These tests include two parts: nerve testing (nerve conduction studies or NCS) and muscle testing (electromyography or EMG).

NCS testing is done by placing small electrodes on your skin. A stimulator will then deliver small electrical currents to the nerves, which will cause your nerves to fire. The electrical signals that your nerves and muscles produce are picked up by our computers and we then interpret the information to see how quickly or slowly your nerves are functioning. These results are compared to average nerve function speed to see if your nerves are reacting properly.

EMG testing is done by placing small needles in the muscles of your arms, legs, or back so that we can evaluate the electrical activity caused by muscle contractions. Our specialized computers will be able to see and hear how your muscles and nerves are functioning. This test can also determine whether or not your muscles are receiving signals from your nerves properly.

"I had a great experience in Dr. Chen’s office. Before I went there, the traditional MDs’ diagnoses were that my vertebrae degenerations would have made my back / leg pains persistently recur for the rest of my life. However, the doctors in Dr. Chen’s office and the Chief Physical Therapist there, Mrs. Chen (Ph.D. of Biology and M.S. of Physical Therapy), miraculously cured my pains, at least not recurring for the past several years."
