Somatosensory Evoked Potential (SEP)

The test

• You can print the pamphlet about the Somatosensory Evoked Potential (PDF).
• A somatosensory evoked potential (SEP) checks how well the spinal cord conducts a message from the arms and legs to the brain.
• Your child will feel a "tingling" sensation, or their big toe or thumb might twitch.
• This does not hurt but may feel uncomfortable.

Preparation for a somatosensory evoked potential

• Most children are sedated for this test as it is very important for them to lie still. See Preparation for Being Sedated.
• Please sleep deprive as well.  See instructions for Sleep Deprivation.  
• Please wear loose clothing or bring shorts and a t-shirt to change into.
