The National Biomechanics Institute is the preeminent biomechanics consulting firm in the United States. The interdisciplinary academic, research and professional backgrounds of our partners, staff, and affiliates allow NBI to perform in-depth scientific research and analyses, as well as rapid-response evaluations. NBI’s experts use scientific and engineering principles to analyze human motion, loading and injury potential in a variety of transportation, industrial, and recreational settings. Our biomechanical analyses involve scientific evaluation of human movement and loading during a dynamic event, and the evaluation of that movement for purposes of assessing injury mechanics and injury potential. We examine the relationships between the forces applied to the human body, the motions of the human body, and the physical, mechanical damage to structures of the body. We aim to relate these forces and motions to conditions that are diagnosed by medical personnel. Through additional accident reconstruction and human factors analyses, we analyze the role of humans in a case, from accident causation to injury mitigation. Using this interdisciplinary approach and adhering to the scientific method, NBI is able to determine whether a claimed injury is consistent with the exposure to a certain action or environment.
