Electromyography & Nerve Conduction Studies

Dr. Devney has achieved board certification in Electrodiagnostics from the American Board of Electrodiagnostic Medicine (ABEM).  The designation of ABEM Diplomate indicates the highest level of competency and expertise in the electrodiafnostic evaluation of disorders of the neuromuscular system.

Why am I being sent for an EMG and Nerve Conduction study?
You are being sent for an electorodiagnostic assessment because you have numbness, tingling, pain, weakness or muscle cramping.

What does the nerve conduction study show?
NCS's show how well the body's electrical signals are traveling along a nerve.  This is done by applying small electrical impulses to the nerve and recording information such as electrical impulse speed and amplitude.  Several nerves are often tested.

What happens during and EMG?
For this portion of the test, a small pin is placed into various muscles to see if there are any problems.  A new pin is used for each patient, and is thrown away after the test.  There may be a small amount of discomfort while placing the pin.  The doctor tests only the muscles necessary to determine what is wrong.  The doctor will look at and listen to the electrical signals that travel from the pin to the EMG machine.  The doctor then uses his medical knowledge to determine what could be causing your problem.

How long will the test take?
Usually 30-60 minutes depending on the extensiveness of the study.

How should I prepare for the test?
You can do any of your normal activities like eating, driving, and exercise before the test.  Take a bath or shower the morning of the exam to remove oil from your skin.  Do not apply body lotion before the exam.  Tell the doctor if you are taking blood thinners (like Coumadin or Plavix), have a pacemaker, or have hemophilia.
