During this test, you will be lying on an examination table, next to an EMG machine (which looks like a desktop or laptop computer). The test consists of two parts, though at times one may be done without the other. The first part is called Nerve Conduction Studies. In this part some...
The person who administers the test will explain the procedure. Often muscle activity is monitored through a speaker during the test, which may make a popping or soft roaring noise. The EMG technician will be looking at an oscilloscope, which looks like a small TV set during the procedure. ...
Tell the healthcare provider if you have any metal in or on your body. Myelography is an x-ray of your spinal cord. Contrast liquid will be injected into the area around your spinal cord before the pictures are taken. An electromyography (EMG) is a test that checks for damage to the ...
Blood testswill show the level of damage to your muscles. An electromyography (EMG)is used to test the function of your muscles and the nerves that control them. Wires are placed on the area of muscle being tested. Needles that enter your skin may be attached to the electrodes. The electr...
Hemoglobin A1C is a common test to determine your averageblood sugarlevels for the past three months. Normal A1C level is below 5.7%, while levels between 5.7-6.4% indicate prediabetes. Anything 6.5% and above means you have diabetes.
In addition to these traditional techniques, biosensor recordings such as eye tracking, EEG, EDA / GSR, EMG, and ECG, as well as computer-guided automatic facial expression analysis procedures, are used. Check out: What Is Facial Expression Analysis? (And How Does It Work?) All of these qu...
Nerve conduction velocity test vs. electromyography NCV vs. EMG Nerve conduction studies are often done at the same time as electromyography (testing muscle response). By comparing the results of how quickly the nerve conducts electricity and how a muscle responds to the signal to contract, it ma...
An EEG is a test that detects the brain's electrical activity. Used to evaluate head injuries or neurological disorders, an EEG...

Once the determination is made that a patient has a clinical picture consistent with possible nerve damage, the EMG/NCS study is scheduled. The test generally starts with the NCS, or nerve conduction studies portion and involves the patient lying flat on a comfortable table. Then, grounding and...
