What is an evoked potential study?

A stimulus is used to get a response (evoke) from the nerves. This response is called an impulse (potential). This test measures and records how long it takes nerves to respond to the stimulus.
There are three types of this test to study your child’s nerve pathways. 

What needs to be done before the test?

How is it done?

Small electrodes will be placed on your child’s scalp, neck, limbs or back depending on which test is being performed. The electrodes record electrical impulses by the nerves. These are held in place with a clear glue or paste. When the electrodes are removed, the glue or paste will be washed off. There is no need to shave or cut your child’s hair. 

Your child will not receive any shots. During the somatosensory test, your child will feel a tingling feeling on the skin when the nerve is stimulated.

How will I get results of the test?

The results of the test will be sent to the doctor who ordered the test in about 7 to 10 business days. Your doctor will call you to explain the results. 


Call your child’s doctor, nurse, or clinic if you have any questions or concerns or if your child has special health care needs that were not covered by this information.
