Nerve conduction tests may take from 15 minutes to 1 hour or more. It depends on how many nerves and muscles your doctor tests.
You will be asked to sit or lie down for the test. A neurologist will locate the nerve(s) to be studied. A healthcare provider will attach a recording electrode to the skin over your nerve, using a special paste. He or she will then place a stimulating electrode away from the recording electrode, at a known distance.
How the Test will Feel. The impulse may feel like an electric shock. You may feel some discomfort depending on how strong the impulse is. You should feel no pain once the test is finished.
The tests usually take 60 to 90 minutes. You can do any of your normal activities, like eating, driving, and exercising, before and after the test. There are no lasting side effects from the tests.
In order to get the best results, it is important for your child to be very still and relaxed for this test. We can get the very best results when your child is asleep or very, very drowsy. We recommend that all children be given a mild sedative one hour prior to the time of testing.
Nerve conduction studies are done to: Find and evaluate damage to all the nerves that lead away from the brain and spinal cord to the smaller nerves that branch out from them. Help diagnose nerve disorders, such as carpal tunnel syndrome or Guillain-Barré syndrome.
Do not smoke for 3 hours before the test. Do not eat or drink foods that contain caffeine (such as coffee, tea, cola, and chocolate) for 2 to 3 hours before the test. Wear loose-fitting clothing. You may be given a hospital gown to wear.
Five or more needle insertions may be necessary for the test. You may experience slight pain with the insertion of the electrode, but it is usually painless.
It is best to wear loose clothing that is easy to remove. Do not wear long underwear, pantyhose etc. You may bring a pair of loose-fitting shorts and t-shirt if you wish.
Nerve conduction studies help diagnose nerve damage or disease. When EMG tests and nerve conduction studies are done together, it helps providers tell if your symptoms are caused by a muscle disorder or a nerve problem.

When compared with MRI, nerve conduction studies assess the physiological integrity of the nerve function, while MRI identifies structural abnormalities.
Nerve pain often feels like a shooting, stabbing or burning sensation. Sometimes it can feel as sharp and sudden as an electric shock. You may be very sensitive to touch or cold.
Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft). These procedures can help your nerves regrow.
Localization: Distal third of the leg, immediately posterior to the tibia at a depth of 2–3 cm. Needle insertion just behind the ventral (posterior) surface of the tibia usually passes through some of the soleus, which can be distinguished by selective activation.
Pain is the most common complication of EMG2 causing some level of discomfort in all patients either from the nerve conduction portion or the needle examination. Most surveys find pain more common in the needle portion. The study is typically well tolerated but for some patients it is nearly unbearable.
It is rare that patients need sedation. If you feel you need something, Valium or one of its relatives, (Xanax, Ativan), is usually prescribed. You need to be awake for the procedure, so whatever you take should allow you to be relaxed and not asleep. Plan on resuming normal activities after the procedure.
What should I expect after an EMG test? You may have sore or tender muscles for a few days after the test. The muscle soreness isn't usually severe and should get better in less than a week. You may also see some bruising where the needles entered your skin.
Electromyography (EMG) is a safe and relatively painless test to discover whether your nerves are functioning properly. An EMG is one of the tools we use to detect and diagnose pinched nerves.
An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.
For these mild nerve injuries, nonsurgical treatment options include medication, physical therapy or massage therapy. Peripheral nerve surgery can reconstruct or repair damaged nerves. You may need surgery to repair severely compressed nerves, cut nerves or nerves that are not healing on their own.
Electromyography (EMG) is used to record the electrical activity in muscle. It can identify abnormalities in the muscles or nerves resulting from peripheral neuropathy, nerve degeneration or damage to the protective covering (myelin sheath) that surrounds the nerves in your brain or spinal cord.
