Question:

Answer:

First, your child will lie on an exam table and a clinician will move his or her legs to see how they bend. Then, small reflective balls will be placed on the body. Other sensors will be placed on the legs to tell us when the muscles are working. Then, your child will walk back and forth in the lab so that special cameras can take pictures of the reflective balls that he or she is wearing. Computers then analyze these camera pictures and tell us how your child’s legs and body are moving.
