Does it hurt?
Parts of the test are uncomfortable but not severely painful. The anxiety before the test can be more of a factor than the test itself. A majority of the time spent with the patient is setting up the studies and running the computer; a very small amount of the time involves electrical stimulation or use of the pin electrode.
The electrical stimulation of the nerve conduction study could be compared to a static electricity shock from a doorknob after walking across carpet.
The pin insertion could be compared to being pinched by someone's fingernails. (And how do we know this? We have done it on ourselves first!)
Is sedation or anesthesia used?
No, the test is fairly well tolerated and the patient needs to be awake to follow instructions, if possible, during the exam. However, a very mild dose of medication can be arranged if a patient or caregiver feels that it would be advisable based on past experience with procedures.
Please call the Pediatric Rehabilitation office at 513-636-7480 if this is a consideration or if you have questions.
Are there any side effects from an nerve conduction test or EMG?
There are no real side effects, but patients may experience some minor irritation at the pin insertion sites. Otherwise, there are no lasting effects from either the nerve conduction test or the EMG.
Is there an age limit on this test?
No, an EMG can be performed on any individual from infancy to old age. Infant and toddler exams can be more restricted because of inability to cooperate because of their young age.
Can the caregiver be in the room during the exam?
Yes, we have no restrictions on caregiver / parent presence in the room. It is up to these individuals as to whether they prefer to be in the room or not. It most cases, the parents / caregivers choose to stay in the room.
What should be done if the child becomes frightened during the test?
Reassure the child that everything will be explained to them before anything is actually done and that most children do very well during this test.
We make special effort to make the child as comfortable as possible. We have a large mat table where they can lie down and they can bring their favorite music on a portable player with headphones if this would be helpful (or anything else that can distract from the test). We also have a TV with DVD player available.
Will I get test results the same day?
The examining physician can give you an idea of any obvious abnormalities at the end of the test. However, more detailed interpretation will be done at a later time with a full report sent to the physician who referred the child.
The referring physician can better discuss the results as he / she will have knowledge of the EMG results along with the results from any other tests being done.
Who does the actual testing?
A physician (MD) who has received specialized training and has extensive experience will perform the test. At times there may be a physician in training present who will be observing or performing certain parts of the exam under direct supervision of the attending physician.
