What is an electromyogram?

Electromyogram (EMG) is a medical test that is performed to measure electrical activity in the muscles at rest and during contracture. The aim of this diagnostic test is to learn more about the cause of the patient's muscle weakness or other muscle problems and distinguish between the problems that come from the muscles and the problems that come from the nerves. Electromyograms can be carried out in a medical office, clinic or hospital using a machine known as an electromyograph and are outpatient procedures. Electromyogram studies electrical pulses in the muscles, while the nerve lines test studies nerves in terms of electrical pulses. Looking at both results, the doctor can determine whether the nerves or muscles are responsible for the patient's health problem and determine the severity of the patient's condition.

v e electromyogram, electrode needles are inserted into the muscle and the deduction is taken, while the muscles are at rest than the patient is asked to close the muscle to take second reading. SomeElectromyograms are performed more with surface electrodes than needles if the doctor feels that needles would be invasive or unnecessary. The nervous lines test uses surface electrodes, with one electrode issuing a slight electrical pulse, while the others have read this pulse as the nerves are performed.

This test can be slightly painful because it hurts to put needles. If only superficial electrodes are used, the patient should not take pain or discomfort. The results can be read on the print that provides information collected by an electrician machine used to perform a test in a format that is easy to understand and read. Once the test is lit, the patient may usually leave immediately if further testing has not been planned or the doctor wants to discuss the results with the patient.

combination of electromyography and nerve conduct studies can be used to diagnose or exclude large groupsY conditions related to the nervous system and muscles. Information from these tests can also be used to monitor the procedure of degenerative conditions or to determine how well the patient reacts to medicines. The cost of the electromyogram varies depending on the clinic performing the procedure, but the test is usually covered with insurance because it is a necessary diagnostic tool.
