Nerve Conduction Study (NCS): Small electrodes are placed on your skin to deliver brief, mild electrical impulses that measure how well your nerves transmit signals. You may feel a quick tingling or tapping sensation.
Electromyography (EMG): A very thin, sterile needle electrode is inserted into selected muscles to evaluate their electrical activity. You may experience mild discomfort during needle insertion, and some muscles may feel sore for a day or two afterward.
The entire study typically takes 45-60 minutes, depending on the number of nerves and muscles being evaluated.
You can return to your normal daily activities immediately after the test.
What to expect
How to prepare
Bathe or shower the day of your appointment.
Do not apply lotions, creams, oils, or powders to your skin on the day of the test, as they can interfere with the recording electrodes.
Wear loose-fitting, comfortable clothing that allows easy access to the area being tested.
Continue taking your regular medications unless your healthcare provider instructs you otherwise.
Inform your provider if you:
Take blood thinners (such as warfarin, apixaban, rivaroxaban, or clopidogrel).
