Dr. Treinen has also attained certification for Low Speed Rear Impact Automobile Crash Reconstruction. This accredited post-graduate course is an auto crash reconstructionist (ACR) program offered by Spine Research Institute of San Diego in conjunction with the Engineering Extension Service of Texas A&M University System. This program provides firsthand experience of actual full-scale, human volunteer crash testing of various types of crashes with various types of human volunteers and crash test dummies so that we can better understand how people can get hurt in car crashes. In these studies the vehicles, the human volunteers, and the crash test dummies are all hooked-up to multiple accelerometers and then the actual crashes are recorded with high-speed video cameras. Before and after the crashes the vehicles and the human subjects are studied extensively to determine what damage/injuries are sustained from the given crashes. The data from the accelerometers is collected and compared with the vehicular damages and reviewed through the lenses of the high-speed video cameras. This is the only such course conducted in the world. Completion of this course certifies that its graduates have cutting edge knowledge into how occupants sustain injury in auto crashes.
