By: | Tags: | Comments: 0 | October 11th, 2017


Please arrive 15 minutes prior to your appointment time, if you are an established patient at the Jewett clinic, and 30 minutes prior to your appointment time, if you are new to Jewett. This will help us see you on time, and will allow us to provide the highest quality care to you, by having all your medical paperwork up to date.

You can take all your normal medications prior to the test. Medications will not affect the test results. Even anti -inflammatories, pain medicines and nerve pain medicine (such as Gabapentin or Lyrica) will not affect the test results. Please tell the technician or physician if you are taking blood thinners, but do not stop taking them as scheduled.
You can eat as normal before the test. No fasting is needed.

Please DO NOT apply any lotions, creams or oils to the skin on any of your extremities for 48 hours prior to the test. This significantly interferes with NCV testing, and occasionally, repeat testing at a later date is required, if there is still residual lotion on your skin. Bathing or showering the morning of the test is also recommended. We want you to have the most accurate test as possible.

Please dress in clothing that permits full access to the area being tested. This may include shorts with an elastic waist, if we are testing your legs, or, a loose fitting short sleeve shirt or tank top if we are testing your arms. If you are asked to remove clothing, we will be happy to give you a gown to wear. Please bring a jacket or sweater to keep your extremities warm prior to testing, both in the lobby and exam room. Warm extremities will increase the accuracy of your test.
If you normally wear compression stockings on your legs, please wear them all day, up until your appointment time. We can remove them for you at the time of the test. Any excess swelling can interfere with your test results, and occasionally, EMG/NCV testing cannot be performed if there is severe swelling. Your test will not be accurate if there is moderate or severe swelling.

The physician performing your test will need to know if you have certain medical conditions. Tell the EMG scheduler, as well as the technician and /or physician performing your test, if you:
*have a pacemaker, cardiac defibrillator, spinal cord stimulator, or other implanted electrical device
*take blood thinning medications such as Plavix, Coumadin, Xarelto, Eliquis, Pradaxa, aspirin or others
*have hemophilia, ITP, or blood clotting disorders or other bleeding disorders
*have lymphedema or severe swelling in the extremity we are testing

The duration of the EMG/NCV test is different for each person, depending on what part of your body is being tested. The actual EMG/NCV procedure normally takes between 45 minutes and 1 hour to complete. However, please plan to be at our office for at least 1 ½ hours for your entire appointment. Extra time is usually needed for checking in at the front desk, finishing paperwork, changing into a gown if needed, explaining the procedure to you, and in some cases, explaining results after the test. If you are a new patient to the Jewett Clinic, please plan to be at our appointment for up to two hours. Some patients have more complicated medical conditions that require longer testing time as well, and this can occasionally take up to two hours.

The EMG/NCV exam room is small, and no noise, movement or distraction is permitted during the EMG/NCV test. Your nerve test will be more accurate, more thorough and complete if your family and/or friends wait in the lobby. In special circumstances, companions may be allowed in the exam room. Children and infants are not allowed in the exam room, for safety reasons.

Phones may be allowed in the exam room, only if turned on silent. Phones or other electrical equipment cannot be on the exam table during the exam, for safety reasons, and because the electrical signals emitted by any electrical device can interfere with the test results. The test results will be shared with you after the test, either by the physician performing the test, or at a follow up visit, by your referring provider.

If you have any questions or concerns regarding your upcoming test, we will be happy to answer them for you. Please call our EMG scheduling line at 407-643-1329 for any questions, or see our website at www.jewettortho.com , under the specialty “Electrodiagnostic Medicine” for more information.
