EMG & NCS

Dr. Robinson

Ayse Lee-Robinson M.D., Board Certified in 1989 by the American Board of
Neuromuscular & Electrodiagnostic Medicine and in 1986 by the American Board of
Physical Medicine & Rehabilitation, has over 20 years experience performing EMG and NCS diagnostic studies. The following frequently asked questions will provide some basic information concerning these studies.

What are EDX Studies?

The Electrodiagnostic (EDX) studies your doctor has recommended are tests that will study your muscles and nerves to see if they are working right.  Your EDX studies will include two different tests – Nerve Conduction Studies (NCS) and Electromyogram (EMG).

Why are EDX Tests Ordered?

EDX tests are usually ordered when there is numbness, tingling, pain, weakness, and/or muscle cramping.  These tests will check how well nerve roots, nerves, nerve-muscle junctions and muscles are working.

What are NCS or Nerve Conduction Studies?

NCS test how well signals travel along a nerve and can help find the cause of abnormal nerve function.  Signals are made to travel along the nerve by applying small electrical pulse or shock to a nerve and recording the transmission of this impulse by the nerve. 
The small electric pulses cause a short, mild tingling feeling.  Different nerves will be tested based on the problems you are having.

What is an EMG or Electromyogram?

During this part of the exam, a thin disposable, Teflon coated wire (recording electrode) is inserted into several muscles to record the electrical activity within the muscles.  There may be a small sting when the recording electrode is put in.  Dr. Lee-Robinson examines only the muscles necessary to decide what is wrong.  During the EMG test Dr. Lee-Robinson will look at, listen, and interpret the electrical signals recorded from the muscle by the recording electrode.  She will then use her medical knowledge to determine if there is any abnormal nerve, muscle, nerve to the muscle, or nerve-muscle junction function.

Preparing for Your Test

Tell Dr. Lee-Robinson if you are taking Aspirin, blood thinners like Coumadin, have a pacemaker, or have hemophilia.  Take a bath in order to remove oil on you skin.  Do not use body lotion on the day of the test.  If you have Myasthenia Gravis, inform the doctor’s office of your medication & medication schedule for instruction on taking your medications before the test.

How long will Testing Take?

Your testing will take 45 to 90 minutes.  You can do any of your normal activities, like eating, driving and exercising before the tests.  You can also do your normal activities after the tests.  There are no side effects from this test.

When Will I Know the Results of the Tests?

Ayse L. Lee-Robinson, M.D. will analyze and interpret your test results as she is testing you.  She will usually review the basics of her findings with you towards the end of your test. A written report with details of your results will then be forwarded to your referring doctor within 48 working hours of your test. 

Common Problems EDX Studies can Diagnose:

Pinched nerves at the:

  1. Wrist (Carpal Tunnel Syndrome)
  2. Elbow (Ulnar Palsy)
  3. Knee (Foot Drop)
  4. Neck (Cervical Radiculopathy)
  5. Back (Lumbar Radiculopathy)

And:

  1. Polyneuropathy (Diseases of the Nerve Fibers)
  2. Myopathies (Muscle Diseases)

What Kind of Training do Doctors Board Certified in Neuromuscular and EDX Medicine Have?

M.D's. who are Board Certified in Neuromuscular & Electrodiagnostic Medicine have completed medical school and are M.Ds.  Then an additional 3 or 4 more years training in a residency program is required for the specialty.  Board Certification then requires meeting all training requirements and “a passing performance” in an oral, written and practical examination by the American Board of Neuromuscular & Electrodiagnostic Medicine.
