Clinical Electrophysiology Laboratory
In our neurology department, electrophysiological tests are used in the diagnosis of all neurological diseases and many neurological diseases due to drugs used for various reasons. These tests are electroencephalography (EEG), electromyography (EMG). These tests are not just a group of laboratory tests, they are an extension of neurological assessment. They do not only confirm or falsify a clinically suspected condition; they reveal ambiguous, silent, or previously unsuspected abnormalities, and they also allow to determine the location, type, and degree of the abnormality.
EMG is the examination of nerves and muscles in our body by electrical methods. Electrical conduction functions of nerves are measured using linear electric current at an intensity that will not disturb the patient that much. For this purpose, a low-intensity electric current is applied to the fingers and skin areas on the nerves, and this current is collected from another part of the nerve or skin with computer tools and measured. Thus, it is understood whether the nerve is functioning properly or not.
In which cases electromyography (EMG) should be performed;
Numbness or weakness in the arms and legs,
Numbness in dialysis patients,
Numbness due to diabetes,
Frequent numbness, burning and pain in the hands and feet,
In people working exposed to toxic substances,
In rheumatic diseases,
It is used in the detection of sensory defects due to drug use and poisoning.
How is EMG made?
EMG basically consists of two main examinations: Nerve conduction studies and needle EMG. These tests include different tests among themselves. The doctor who takes the EMG decides which tests will be performed on which patient. Nerve conduction examination is performed with low-voltage and very short-term electrical stimulations. In this way, the functions of movement and sensory nerves are tested. Needle EMG, on the other hand, is a test that provides information about both the muscle itself and the nerve structures that operate that muscle, which the muscles examine by placing a thin needle electrode.
Which Diseases Is EMG Requested To Diagnose?
EMG test is often required for back and neck hernias, nerve diseases, nerve entrapment, nerve cuts, sciatic nerve injuries, spinal cord diseases, muscle weakness, numbness of the hands and feet, nerve damage in diabetes.
Diseases diagnosed by EMG test
Polyneuropathies (multiple nerve ending inflammations)
Carpal tunnel syndrome (nerve compression in the wrist)
Ulnar groove syndrome (nerve compression at the elbow)
Root pressure nerve compression due to waist and neck hernias
Nerve injuries that occur in babies during birth
Injuries, crushes and ruptures of nerves
Nerve involvement due to diabetes.
How long does EMG take?
EMG is a dynamic test. The doctor can extend the examination and perform additional examinations depending on the situation. Therefore, depending on the disease, it can take between 5 minutes and 1 hour. What is EEG? It is a test required in many brain diseases, especially in epilepsy, in which advanced computer system is used to determine the bioelectrical activity of the brain, and in all kinds of consciousness changes that may be due to metabolic, inflammatory and toxic causes. Special creams, electrodes are glued to certain areas of the head. Bioelectric currents coming out of certain areas of the brain are recorded and examined on the computer. During the examination, electricity is not given to the brain. It is absolutely not harmful to the patient. Electrophysiological problems related to the brain are detected and treatment is directed in case of disease. In our center, patients over 12 years of age can be monitored for short-term sleep (1-2 hours) EEG in addition to standard EEG examination according to the condition of the disease. Routine EEG (Normal EEG ) : lasts from 20 to 30 minutes. Sleep-Wake EEG: It lasts an average of 1 hour (20 minutes awake, 40-60 minutes asleep),
In Which Problems does the EEG Method Applied?
In the diagnosis and follow-up of epilepsy, the most common reason for the diagnosis of epilepsy (fainting, convulsions)
Diagnosis of epilepsy in cases such as loss of consciousness, fainting
In some sleep and behavioral disorders,
In many nervous diseases
In the investigation of the causes of headaches,
In the evaluation of brain function,
EEG shooting is required.
Routine (Normal) EEG:
Alertness is known as EEG si. The shooting time lasts an average of 20-30 minutes. It is done by placing an average of 23 small electrodes on the scalp of the hair with the help of a kind of gel and recording the electrical activity of the brain with the help of a computer. It is evaluated by a neurologist and EEG Trases are printed out from the computer.
It is an average of 1 hour. It is performed in such a way as to see at least one sleep cycle (40 minutes) and 20 minutes of wakefulness for a short period of time.
At the beginning of the sleep-alertness EEG examination, routine(wake) EEG records are obtained. After 10-20 minutes of wakefulness, the patient is allowed to sleep and the examination continues. Sleep helps reveal abnormal electrical activity in the brain.
