Both tests are usually done together with the NC being done first.

The test duration is approximately 1 hour.

Most children tolerate the procedure well, but some patients benefit from sedation to help them lay still, particularly during the EMG. See the instructions for sedation. 

• The NC test is done first. Electrode stickers will be put on the wrist or ankle. Your child will feel a tingling sensation or tapping which will make the fingers or toes jump. This can feel strange, but doesn't usually hurt. 
  
• If your doctor has requested an EMG, this will be done next.
  
• The tip of a very small, thin needle will be placed into the muscle and the doctor will ask your child to move in a certain way.

Preparation

Sleep deprivation is not necessary for these tests.

Have your child wear loose-fitting clothing that can easily be pulled up over elbows and knees (a t-shirt and shorts/track pants work best).

Bring a comfort item if you feel it will help (stuffed toy, soother, blankie, etc).
