The pulse might feel like a tingling in your muscle. This is what stimulates the nerve to send a signal to your muscle.
You’ll sit or lie comfortably while your provider places electrodes on your skin.It does, however, use small electrical pulses. What Does a Nerve Conduction Study Feel Like?Ī nerve conduction study doesn’t use needles. If you need the test in more than one muscle, your provider will take the electrode out and repeat the process.You will also “hear” your muscles, meaning that you hear the echo of waves being sent through that muscle.
A machine records this activity and shows it on a monitor. The electrode measures your muscle’s electrical activity.After measuring your muscle at rest, your provider may ask you to move the muscle, such as bending your arm.You’ll sit or lie comfortably while your provider puts a very thin needle with an electrode into your muscle.Plus, to help with EMG testing of hand and foot muscles, doctors apply a freezing spray to the area to lessen discomfort.ĭon’t let fear of pain stop you from getting a test that can help doctors diagnose and treat you. The EMG electrode is about the size of an acupuncture needle, so it’s hair-like and goes under the skin easily. In reality, while an EMG test does involve needles and some discomfort, most patients find it easy to tolerate. Studies find that people expect EMG tests to be more painful than they actually are. Whether EMG tests are painful is a topic of some discussion. You’ll be able to do whatever activities you had scheduled. There is no recovery time involved with either test. Your doctor will likely perform them during the same visit. In other words, the tests use electricity to help diagnose conditions that involve your nerves or your muscles. These tests are both part of a subspecialty of physical medicine and rehabilitation called electrodiagnostic medicine. This test looks at how well the electrical signals travel from your nerves to your muscles. It examines the electrical signals your muscles make-both when you’re using them and resting them.Ī nerve conduction study is similar to an EMG test, but slightly different. Types of Electromyography TestsĪn EMG test checks how healthy your muscles are. If your doctor wants to see how the signals in your nerves and muscles are working, they’ll recommend you get an electromyogram (EMG) and nerve conduction study (NCS). Specifically, your nerves send signals to your muscles to tell them to move. Your muscles and nerves are full of electrical signals.
