EMG or electromyography is the procedure that is done in order to test the muscles activity. Frequently the EMG test is done along with another test that evaluates the conducting works of the nerves. This is identified to be a nerve conduction study. For the reason the two test are frequently done at the similar day by similar personnel, the danger and methods normally apply to the two tests.
The muscular movement engrosses the action of the nerves and in need of electrical current. The electrical current is weaker compare to the one that can be seen in the wiring in every house. In several medical conditions the electrical activity of the muscles and the nerves is not that usual. To finds and describe these electrical properties in the nerve and in the muscle might aid your doctor to determine the condition that you will have.
The EMG test might help the diagnosis of the compression of the nerve and the injury like the carpal tunnel syndrome, the nerve root injury like the sciatica and with other issues of the nerves and the muscles. Less usual medical condition includes muscular dystrophy, myasthenia gravis and amyotrophic lateral sclerosis. The EMG test is frequently performed once the patients experience unexplained weakness in the muscles. The EMG test aids to determine between the conditions of the muscle in which the problems starts in the muscle and the weakness in the muscle because of the disorder in the nerves. The EMG test can as well as knows the real weakness, in contrast to the weakness from lessens employment due to the pain or insufficient motivation. The EMG test can be utilized also to detach the level of the injury or nerve irritation.
Aside from the help that the EMG test, there are as well as risk in doing this kind of test. People normally acquire tine quantity of irritation while in the process of doing the test due to the pin insertion. The needles that are employed are disposable in order to avoid risk in infection. During the nerve conduction studies, tiny electrodes are being plastered on the skin and put around the fingers. Typically, there are short and mild chock that in a certain way could be horrible. Some of those who already experience it felt that it is somewhat irritating.
During on the process of EMG test, tiny pins and needles are place within the muscles to calculate to the electrical activity. The needles that are not being employed are not the same as the one that are being utilized in injecting medications. Due to the medication that was injected, the felt pain is lesser compare to shots. You will be required to contract your muscles by moving a little volume while conducting the test.
The person who will conduct the test will explain to you the whole method. Frequently the activity of the muscle is monitored by means of a speaker during doing the test that might create a soft roaring or popping noise. The technician of the EMG will look at the oscilloscope that looks like a tiny television set while doing the test. The procedure will take place for about 30 until 60 minutes
