Biomechanical Analysis
& Investigation


At Pittsburgh Biomechanics, we provide our clients with the Biomechanical Analysis and investigation that they need to consider when involved in accident related cases. Our engineers help our customers, including legal and insurance agencies, understand the role that biomechanics can play in a wide range of accident scenarios. The Biomechanical Analysis contains five key components, including:

Material Review ▸

Accident Analysis/Reconstruction ▸

Kinematics of Human Motion ▸

Injury Analysis ▸

Expert opinion/conclusions ▸

Experts from Pittsburgh Biomechanics have been relied upon countless times to provide testimony defending the resulting conclusions from our comprehensive Biomechanical Analysis Report.

On-site Inspection

On-site inspection of evidence (i.e., vehicles, accident scene, safety equipment, etc.) when reconstructing an accident helps to better understand exactly how an accident could have occurred. It allows the opportunity to gather photographs and measurements that will ultimately be used in the final analysis when recreating an accident scenario.

Exhibits / Graphics

Courtroom graphics and exhibits are an important tool to help the general public to better understand the science and engineering involved in injury biomechanics.


Pittsburgh Biomechanics completes a thorough review of all materials pertaining to a subject incident.  This material includes, but is not limited to:

  • Police Accident Report(s)
  • Occupational Incident Reports
  • Medical Records
  • Photographs
  • Witnesses’ Testimonies
  • Legal Documentation (Verified Bills of Particulars, summons, etc.)
  • Vehicle Repair Estimates

Additionally, our engineers and scientists provide on-site inspection of evidence, if available and applicable.

All reviewed materials are identified in our final Biomechanical Analysis where all medical records are summarized and the subject incident explained in detail.



The majority of Pittsburgh Biomechanics’ cases involve injuries resulting from vehicular accidents . We utilize our expertise in accident analysis and reconstruction to quantify the severity of an automobile incident in terms of velocity and/or acceleration changes of a vehicle during the impact phase of an accident. We do this by implementing the laws of physics and engineering principles in evaluating the damage to vehicles and calculating the forces required to deform vehicular structures.  All contributing factors are considered, including but not limited to road conditions, vehicle geometry/dimensions, angle of impact, and the role of vehicle occupants.

Once engineering analysis from reconstruction is complete, a final report is presented with supporting data. As expert engineering witnesses, Pittsburgh Biomechanics explains the results of the reconstruction, answers any questions related to the investigation, and/or provides testimony if necessary.



In motor vehicle accidents, vehicle occupant motions can be assessed based on the determined severity of the incident and the laws of physics. Interactions between the human body and interior vehicle structures are also examined. The forces and loads acting on vehicle occupants, as calculated during the accident analysis, are compared to data available from biomechanical literature. This literature includes crash tests and research studies of human body mechanics and tissue tolerance. An evaluation is then performed to determine if the motions and forces experienced by a vehicle occupant during a subject incident could be related to his or her alleged pathologies.

Outside of vehicular accidents, but in similar fashion, human motion is assessed based on the severity of an incident and the laws of physics.  All interactions between the human body and outside structures are examined to determine the loads and forces acting on a person while involved in an accident. As with vehicular accidents, an evaluation is performed to determine if the motions and forces experienced by a person during a subject incident could be related to his or her alleged pathologies.



In any personal injury case, it must be determined if the alleged pathologies were a direct result of the incident.  Biomechanics, by definition, is the science of how the human body responds to applied pressure and internal forces.  Pittsburgh Biomechanics evaluates the mechanism of injury to determine if the forces applied exceed the strength and tissue tolerances of the involved person(s).  Our experts are oftentimes called upon during litigation proceedings to provide this analysis and testify regarding the causal relationship between the claimed injury and the subject incident.



Pittsburgh Biomechanics concludes the biomechanical analysis with the determination if a subject accident could have caused the injuries being claimed by an individual.  Our opinions are presented with a reasonable degree of medical and biomechanical engineering certainty. They are based on the information reviewed as well as the education, experience, and knowledge of our engineers and scientists.
