Thirty-seven SID side impact sled tests were performed using a rigid wall and a padded wall with fourteen different padding configurations. The Thoracic Trauma Index (TTI) and Average Spine Acceleration (ASA) were measured in each test. TTI and ASA were evaluated in terms of their ability to predict injury in identical cadaver tests and the harm or benefit of padding of different crush strengths. SID ASA predicted the injury seen in Wayen State University-Collision Deformation Classification (WSU-CDC) cadaver tests better than SID TTI. SID ASA predicted that padding of greater than 20 pounds per square inch (psi) crush strength is harmful (ASA greater than 40 g's). SID TTI predicted that padding of greater than 20 psi predicted that padding of greater than 20 psi crush strength is beneficial (TTI lower than 85 g's). SID TTI predicts the benefit of lower impact velocity. However, SID ASA appears more useful in assessing the harm or benefit of door padding or air bags. (A)
