These sisters clearly have a strong bond that nothing can break. When dealing with something like cerebral palsy, that sisterly support is sure to be a big help. Cerebral palsy is a movement disorder that can cause poor coordination, stiff or weak muscles, trouble swallowing, speech issues, tremors, and more. With CP, symptoms can vary greatly from person to person. There are also a variety of causes, most of which occur during pregnancy. Today, management of cerebral palsy is centered on the best ways to maximize independence and overall healthy development. This is done by using medications, therapy and surgery, when necessary. There is also new evidence to suggest that intensive therapy in childhood can help greatly.
