When would my doctor consider an electrodiagnostic (EDX) study?
This study is considered when the reason for pain or tingling or weakness is not clear. This study can also be used to determine the severity of a nerve injury or how badly a nerve is being pinched in the neck or back. Occasionally other conditions can mimick a pinched nerve in the back or neck. Electrodiagnostic studies can also help determine if other conditions are occurring.
What should my doctor know about me to determine if I should have an EDX?
The doctor performing the electrodiagnostic test will ask questions about the nature of your pain, tingling and weakness. This will help them determine which nerves and muscles to test. The physician may also ask questions about other conditions which may affect the nerves and muscles, such as diabetes and thyroid problems. Your doctor should know if you have ever had a neck or back surgery.
Are there any reasons I should not have an EDX study?
If you are on blood thinning medications, such as aspirin, plavix, heparin or warfarin (Coumadin), the physician may not perform certain portions of the test. If that information is absolutely necessary, you may be asked to stop blood thinning medication prior to the electrodiagnostic test. If you have a pacemaker or similar device, certain portions of the test may not be able to performed.
