What is electromyography?
Electromyography (EMG) is a diagnostic medical test that evaluates the activity of skeletal muscle. This test is often performed in conjunction with a test called Nerve Guide. This allows the physician to evaluate muscle health simultaneously with testing the activity of the nerves that control these muscles. Electromyography and nervous lines tests can be used to diagnose muscle and nerve diseases such as muscle dystrophy, amyotrophic lateral sclerosis, carpal tunnel syndrome and ischias.
The activity of muscles and nerves creates electricity that works to say the muscles to move, because cell neurons cells broadcast electrical signals that cause muscle cells to withdraw. Healthy muscles and nerves generate characteristic electrical patterns during activity. When someone undergoes electromyography, its muscle electrical activity is recorded and compared with the known normal baseline. This comparison is then used to diagnose muscular disorders. When it is doneAt the same time, nervous activity may also be evaluated for the nerve leadership studies. During this test, several needle electrodes are placed on the patient's skin. The needles are electrodes with a type of electrode with a needle connected. The needle is inserted into the muscle so that its electricity can be seen when muscle move. Electrodes can record electricity emitted muscles and nerves, as well as the strength and speed of electricity transmission. Energy patterns are recorded and interpreted by computer.
No specific preparation is required to undergo EMG, but on the day of the test it is best to avoid using any body creams or skin face creams, as these can reduce adhesive electrodes. Electromyography is not a risky procedure. The amount of electricity to which the patient is exposed. Some people experience discomfort of a similar level of moderate electric shock and jEhly embedded in the muscles cause the level of discomfort of a similar level of injection. There is a very low risk of nerve damage, infection or bleeding caused by the insertion of the needle.
Electromyography in conjunction with the studies of nervous lines can be used to diagnose a wide range of muscle and nerve disorders. In addition to dystrophy that affect muscles, this combination of tests can help diagnose peripheral neuropathy and motor neuron disorders. With this combination of tests, diseases that affect the intersections between nerve and muscle cells such as myasthenia gravis can also be diagnosed.
