How to prepare for the examination

For the EEG test, your hair needs to be clean and dry. Do not use any hair products like hair gel or spray. Furthermore, hair extensions and other additions to the hair should be removed. Take all your regular medication if you need to prior to EEG.

EEG is a painless procedure which is used to measure electrical activity of your brain. The examination includes putting small sensors (electrodes) on your head. The electrodes are wired (or wireless) to the computer, which helps determine your brain’s functioning. Computer measures your electrical brain activity and shows it as wavy curves on the screen or paper. Some disorders, such as epilepsy, can be recognized according to changes of the normal pattern of brain activity. The procedure takes one and a half to one hour. There are a few subtypes of EEG examinations and your doctor will determine which type fits you the most according to the symptoms you have.

EEG after a sleepless night is an examination similar to standard EEG but will require from you not to sleep more than three hours in the last 24 hours before the examination. Children under the age of 12 are required to stay awake from midnight till the time of examination. Do not drink or eat food containing caffeine from midnight to the time of examination. EEG after sleep deprivation lasts 1-2 hours.

For EMG examination, you should shower on the day of examination. Clean your arms and legs thoroughly so the skin can be clean.

Do not use lotions, bathing oils and creams. Wear comfortable and wide clothes which you can take off easily. Eat your normal daily meals.

Take all your usual medications (except in examinations of the neuromuscular junction when our personnel will inform you to avoid taking drugs 48 hours prior to examination which cause the change of function of the neuromuscular junction). Bring a list of medications you take, especially if you take anticoagulant and/or antiplatelet drugs

EMG (electromyography) and peripheral nerve conduction sensitivity (NCS), along with EMNG (electromyoneurography), is a procedure with which electrical activity of certain muscles and nerves is measured. It is most commonly used for examining symptoms such as pain, numbness or muscle weakness. Examination lasts less than one hour. Maximal nerve conduction velocity is the most important information in the examination of peripheral nerve conduction. The examination is usually done separately on the motor and sensory nerves. The symptoms which required this type of examination are usually different motor and sensory disorders. The examination of the nerve conduction velocity is usually done at the end of the EMNG test, and usually on nerve sin the regions of the most prominent changes determined on EMG. The examination includes using a series of mild electrical stimuli which are applied to specific regions on your arms or legs. Although the examination is usually painless, you can experience mild local tingling during it.

Electromyography (EMG) is a technique of examining and recording electrical activity which occurs under muscle activation. EMG is is used as a diagnostic tool in states that include pain, numbness, tingling or motor weakness. The EMG part of the examination includes inserting very thin needles in various muscles (if indicated) and putting a superficial electrode on the skin above the muscle (if earlier diagnosis do not require using needles and with sensitive patients). Superficial electromyography is completely painless while electromyography using needles can sometimes cause discomfort when inserting the needle, but most of the times it is not painful. During examination, you will be asked to flex and relax certain muscles. The results of the examination are available when it ends.

The examination gives us valuable information about the state of the patient's muscles and nerves which help your physician to make a diagnosis and determine the adequate treatment method for your disease or state. The examination leaves no long-term consequences. Symptoms do not have to be present for the results of the test to be reliable.
