This research studied falls in ambulatory children and adults with CP specifically asking how often they’ve fallen, fall-related injuries experienced, circumstances around the fall, the level of fear or concern about future falls, and the extent to which they do or don’t avoid certain activities due to their concern about falling. This study sets a strong foundation for future fall research, quantifying the breadth and depth of the problem across a large spectrum of age and walking ability.
