Part 1 of 3: preparing for the test

  • Anticipate 5-15 minutes of testing per extremity. 

  • Generally 2 extremities are tested, even if you have symptoms on just one side (the other side would be used as your normal comparison for reference). 

  • The amount of time that the test takes depends on your age, medical conditions, severity of nerve damage (if present), and other factors. 

  • Keep the arm(s) and/or leg(s) warm (room temperature) prior to the study.  This will minimize artifact from having a cold extremity, which can interfere the results.

  • If you are planning on a nerve study of your legs, please bring shorts with you.  If you are planning on a nerve study of your arms, please wear a short sleeve t-shirt or tank top.  It helps to be comfortable during the test, and our disposable shorts and shirts are not as comfortable as your own clothes.  

  • You will need to remove any metal jewelry and watches either prior to or during the test.

  • Although Dr Spears is capable of giving medical advice based on the findings, he only has a narrow view of a bigger picture of your present illness.  The provider who ordered the test is ultimately responsible for further management based on the test results. 

  • The results will be summarized by Dr Spears at the end of the test and a report will be sent to your referring provider. If further questions on Dr Spears' advice are desired, an appointment on a non-procedure day would be needed so that he can comprehensively review your present illness.
