Two-year-old Reese has Cerebral Palsy. The muscles on the left side of her body are very stiff, making walking, running, and jumping difficult. But now she's getting a Botox injection that will relieve the muscle stiffness and enable Reese to do things she can't usually do.

"She's very proud of herself, she'll run and she'll say I'm running, I'm hopping you can see her whole personality has changed from it also now that she can do more and that is due to the Botox," said Rachael Fortney, Reese's Mom.

Botox can be a very effective treatment for children with cerebral palsy or who have suffered a stroke.

"Botox is used in adults and in children to treat the stiffness and the cramping of the muscles," said Dr. Paola Pergami, WVU Pediatric Neurologist. "It is a local injection in the specific muscles which is stiff and it will relieve the stiffness of by stopping the transmission of the signal of the nerve to the muscle."

By relieving muscle stiffness, Botox makes physical therapy for children easier and more effective. But the relief is not permanent.

"A standard injection lasts about three months," Dr. Pergami said. "So normally it starts working in about three days to a week. It reaches the real effect in two weeks and it lasts up to two or three months."

The only side effects of pediatric Botox is pain at the injection site and possible muscle weakness for a few days.
