Electromyography (EMG), by definition, is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Electromyography equipment includes tiny devices called electrodes that are used to transmit or detect electrical signals. A nerve conduction study uses electrodes taped to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points. In certain cases, a needle electrode inserted directly into a muscle records the electrical activity in that muscle. An Electromyography test can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

You are being sent for electromyography testing because you have numbness, tingling, pain, weakness, or muscle cramping. Some of the tests that the EMG doctor may use to diagnose your symptoms are nerve conduction studies, needle EMGs, and evoked potentials. The EMG doctor will examine you to decide which tests to do.
Nerve conduction studies show how well the body’s electrical signals are traveling to a nerve. This is done by applying small electrical shocks to the nerve and recording how the nerve works. These little shocks cause a quick, mild, tingling feeling. The doctor may test several nerves.
Make sure to notify your doctor about any over-the-counter or prescription medications you may be taking. It’s also important to tell your doctor if you have a bleeding disorder, or if you have a pacemaker or implantable defibrillator. You may not be able to have an electromyography procedure if you have any of these medical conditions or devices.
It is important to take certain measures for electromyography test beforehand which are as follows.
Also, if you are prone to having cold hands or feet, try to wear warm gloves or socks on the day of your test.
The tests usually take 60 to 90 minutes. You can do any of your normal activities, like eating, driving, and exercising, before the electromyography tests. There are no lasting side effects. You also can do your normal activities after the tests.
An electromyography test is a very low-risk exam. However, you may feel sore in the area that was tested. The soreness may last for a few days and can be relieved with an over-the-counter pain reliever, such as ibuprofen.
In rare cases, you may experience tingling, bruising, and swelling at the needle insertion sites. Make sure to tell your doctor if the swelling or pain becomes worse.
