By activating these nerves, their performance can be assessed. Nerve conduction study – Miniscule electric shocks are employed to stimulate the nerves at several different points.Each needle has a microscopic electrode that measures the normal and abnormal signals given off by a muscle. Needle exam for muscle testing – Extremely thin needles are placed in several muscles.While both might result in a small amount of discomfort, it is so negligible that most patients undergo the procedure without the need for any pain medication. Is an EMG test painful?Īn EMG nerve test might occur in two parts. The length of the procedure hinges on the condition being tested and the results of the test. Duration of an EMG testĪn electromyography test typically takes between 30 to 60 minutes.

In addition to helping your doctor determine the specific location of the injury, the test provides information about the degree to which the muscle and/or nerve damage has occurred.ĮMG testing is being used for a variety of medical conditions ranging from relatively simple like carpal tunnel syndrome to more complex conditions like ALS. Your doctor will order an electromyography test if you are showing signs of muscle or nerve disorder. The test translates the electrical signals into numbers or graphs, which, in turn, helps your physician diagnose your condition. How does it help?Īn EMG measures the muscles response or electrical activity that results from a nerve’s stimulation of the muscle. These nerve cells send out electrical signals that are responsible for muscle contraction and relaxation. The diagnostic test assesses the health of muscles and the nerve cells that control these muscles. What is an EMG test?Įlectromyography is used to determine neuromuscular abnormalities. They are indispensable solutions required to get to the bottom of what causes nerve pain, neuropathy in hands, neuropathy in legs, or several other specific neuropathy types like diabetic peripheral neuropathy and peripheral polyneuropathy, among a number of other debilitating conditions. Often performed at the same time, an Electromyography (EMG) test and a Nerve Conduction Velocity (NCV) test are comprehensive and accurate tests that will help your physician assess whether you have muscular or nerve damage.ĭuring electrodiagnostic testing, both EMG and NCV calculate the amount of electrical activity of your muscles and nerves. If you want to get to the bottom of what’s causing the discomfort, a couple of highly effective tests will give you the answers you seek. When your muscles are weak or sore, or when you experience tingling, numbness or any other abnormal sensation there is a strong possibility that there is a problem with your muscles or nerves.
