NBI - The Leading Biomechanics, Medical, and Forensic Experts – National Biomechanics Institute


Accident Reconstruction

Accident reconstruction applies principles of statics, dynamics and physics to the movements of vehicles before, during, and after a collision.  Through an examination of the respective vehicles, the scene of the accident, and/or still images of the vehicles following the collision, vehicle positions, traveling velocities, change in velocities, directions of impact, and applied forces can be determined.
Utilizing PC Crash 3® software, images and animations reconstructing the accident can be developed as trial exhibits.  Typical cases in which NBI experts are retained include: 
    • Low-Speed (Frontal, Rear-End, Side Impact, Sideswipe)
    • Rollover and High Severity
    • Pedestrian, Bicycle, and Motorcycle
    • Truck and Bus
Biomechanics integrates physics, engineering, and human structural anatomy to determine the motion and loads experienced by the human body.  Using this interdisciplinary approach, Injury biomechanics explores the possible relations between mechanically induced human injury and external events.  Whereas medical doctors are skilled in the art of diagnosing and treating injury, biomechanical doctors deduce injury causation.
Biomechanical experts at NBI are capable at conducting analyses and examining questions pertaining to:
  • Motor Vehicle Accidents
  • Restraint Use
  • Airbag Deployment
  • Slips, Trips & Falls
  • Traumatic Brain Injuries
  • Efficacy of Helmets and Protective Equipment
  • Athletic Apparel and Exercise Equipment
Human Factors & Ergonomics

Human factors & ergonomics examine the interaction between humans, products, processes and systems. By applying principles pertaining to psychology, engineering, industrial design, and anthropometry, human factors scientists aim to optimize occupational health and determine the human related factors that may contribute to an accident.  Application of human factors allows for a determination of pedestrian or driver attention, strategies, visual perceptions and responses during an accident
Medical Analysis
NBI employs, and is affiliated with healthcare professionals across the spectrum of medicine, including medical doctors, doctors of physical therapy, doctors of chiropractic medicine, and nurses. NBI medical doctors have a far ranging set of specialties, including neurosurgery, orthopedic surgery, pain management, anesthesiology, and radiology. When examining medical records pertaining to an accident, NBI medical professionals and affiliates play an integral role in verifying diagnoses and radiological reports. NBI doctors and clinical specialists also examine medical records to determine the necessity and efficacy of treatment plans, including surgical interventions and/or conservative rehabilitation.
