If you’re facing this procedure, let’s remove some of the apprehension by explaining what happens. However, it is not a procedure to be dreaded. In a word, yes, you can expect some discomfort. This is one of the most common questions that patients ask when they’re preparing to undergo an electromyography. The doctor can then look for abnormalities, such as pinched nerves, nerve damage, herniated discs, ALS and other conditions. An EMG measures these impulses through a needle, which acts as an electrode, injected into the muscle tissue. Muscles contract when nerve cells (called motor neurons) send a small electrical impulse into them. Electromyography (EMG) is a test that measures and graphs the electrical activity in your muscles as they move.
