Born with cerebral palsy at a time when doctors recommended institutionalization, the parents of Kathleen Friel insisted that she would be raised at home like any other child. As a young child, “Kathleen taught herself to do everything … her own way. How to fasten buttons. How to cut up food. And when she couldn’t grasp her favorite cereal … she licked her finger and dipped it in. She rewrote the rules for even the smallest movements.” In time, Kathleen would rewrite the rules in the scientific world despite prejudice for the way her body worked. After college, her interest in revising long-held ideas took shape through her study of monkeys with brain injuries to see if they could make new connections in their brain by engaging in repeated movements. It turned out they could, and the research and treatment were transferable to humans with cerebral palsy. Dr. Friel’s accomplishments and personality come through clearly in this well-crafted narrative. End matter provides more information about cerebral palsy and Dr. Friel’s research and advocacy.
