Over time, the way to take care of cerebral palsy has changed from fixing a person's physical problems such as spasticity in one leg or arm. Now, the way to take care of cerebral palsy is about making therapies for the body part of a larger purpose of making the person's quality of life better, helping them have choice and make their own decisions about looking after themselves, and helping them be part of society. Much of children's therapy is about helping them walk better. Roughly 60% of people with CP are able to walk by themselves or with mobility aids when they become grown up.
