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. How should I Prepare For the Test? Tell the EMG doctor if you are taking aspirin, blood thinners (LIKE Coumadin) or have hemophilia.
Can I drive afterwards? You will be able to drive after your test or do anything else that you would normally do.
Few preparations are needed on the day you have an EMG. You do not need to fast, or eat any particular kinds of food before the test. You can drive yourself to and from the appointment, do you do not need to bring a friend or relative with you. You can count on resuming your regular activity after the test is complete.
Often, the nerve conduction test is followed by EMG. In this test, a needle is placed into a muscle and you are told to contract that muscle. This process can be uncomfortable during the test. You may have muscle soreness or bruising after the test at the site where the needle was inserted.
An EMG usually takes 30 to 60 minutes. Afterward, you may be given a pain reliever if you have any soreness. After EMG testing, you may feel a tingling sensation for a couple of days. You may develop small bruises or swelling where the needle was inserted.
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.
As the nerve is stimulated, you will experience a brief electrical shock. This may feel uncomfortable, but it usually isn't painful. The entire procedure usually takes about 20-30 minutes to complete. In some cases, nerves may be tested in multiple locations, which can make the procedure take slightly longer.
The nerve conduction study is generally a safe test. However, there are some minor risks associated with this test: You can get an infection where the needle was inserted. Your doctor will talk with you about steps you can take to prevent infection.
Nerve conduction tests may take from 15 minutes to 1 hour or more. It depends on how many nerves and muscles your doctor tests.
The discomfort, or mild pain experienced by some patients, following the application of electrical stimulation during nerve conduction studies (NCS) is transient and self-limiting and will not initiate or aggravate pre-existing symptoms beyond the duration of the actual investigation.
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. You must tell your examiner if the test is painful because this can interfere with the results.
EMG is a low-risk procedure, and complications are rare. There's a small risk of bleeding, infection and nerve injury where a needle electrode is inserted.
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.
The tests usually take 20 to 90 minutes. You can do any of your normal activities like eating, driving, and exercising before the tests. There are no lasting side effects. You can also do your normal activities after the tests.
Is an EMG test painful? EMG testing may result in some discomfort, but it is usually well tolerated without any need for pain medication.
Radiculopathy and Degenerative Spine Disease
EMG changes are first seen in the muscles closest to the site of nerve injury, underscoring the importance of examination of the paraspinous muscles. A disadvantage of EMG is the delay in the appearance of reliable abnormalities until 7 to 10 days after a root injury.
An EMG test helps find out if muscles are responding the right way to nerve signals. 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.
Why might I need a nerve conduction velocity test? NCV is often used along with an EMG to tell the difference between a nerve disorder and a muscle disorder. NCV detects a problem with the nerve, whereas an EMG detects whether the muscle is working properly in response to the nerve's stimulus.
Nerves recover slowly, and maximal recovery may take many months or several years. You'll need regular checkups to make sure your recovery stays on track. If your injury is caused by a medical condition, your doctor will treat the underlying condition.
Nerve cells can regenerate and grow back at a rate of about an inch a month, but recovery is typically incomplete and slow. This is a complete nerve injury, where the nerve sheath and underlying neurons are severed. If there is an open cut, a neurosurgeon can see the cut nerve ends at surgery and repair this.
Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings. The MRI scan images are obtained with a magnetic field and radio waves.

Nerve Conduction Studies (NCS) and Electromyograms (EMG)
On the day of your test, bathe or shower, washing your arms and legs well to remove body oils. Do not use any bath oils, lotions or powders as they can interfere with testing. Inform your provider if you are currently taking blood thinners or have a pacemaker.
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.
