ARCCA engineers are called upon often to study swimming pool diving accidents that lead to spine and spinal cord injuries. When diving into a shallow swimming pool there is a risk of injury from striking the bottom of the pool head first. If at the time of the head strike the torso is still in motion, the loading from the torso through the neck structure can compress the neck into the stopped head, leading to a neck injury. If sufficient force is present, it can be severe enough to lead to paralysis.
