Electromyography (EMG)

Electromyography (EMG) and other nerve conduction testing is conducted at the Electromyography and Evoked Potential Lab.

An electromyogram is a test that can help determine the cause of symptoms that might indicate muscle or nerve damage. An EMG uses a needle or electrodes that are attached to the skin to measure and record the electrical activity in the muscle. When possible, doctors may ask patients to contract muscles, rest muscles or change their position.

Because few children love needles or large machines, they are sometimes afraid of these tests. Fortunately, there is little to worry about. EMG and other nerve conduction tests are extremely safe and complications are quite rare. These tests can also be done while the patient is under general anesthesia.

We are happy to provide some recommendations for helping your children with fear or anxiety on the day of the test. If your child is of school age, it often helps to explain to them what is going to happen and that they are going to the hospital to have some pictures taken. It is important to be honest and to tell them it is OK to cry if it hurts. We recommend that you tell toddlers the same information but that you wait to tell them until right before the test, as their memories tend to be shorter. Also, we recommend that you tell toddlers that you will be there the whole time. For infants, we recommend bringing a favorite blanket, pacifier or toy.
