Our biomechanical engineers evaluate injury biomechanics based upon environmental conditions and incident dynamics to inform analyses of causation, liability, and extent of damages in complex litigation and claims.

We investigate injury causation in transportation accidents; slip, trip, and fall events; product failure; machinery accidents; and heavy equipment operations.

Leveraging decades of forensic engineering experience, we determine the effects of impact, loading, and torque on the human body analyzing how mechanical forces impact bones, ligaments, tendons, soft tissue, organs, blood vessels, and nerves. Our analyses assist legal counsel and insurance professionals in assessing causation, mechanism of injury, and consistency of claimed injuries in insurance claims and complex disputes.

Biomechanical Engineering in Litigation

Biomechanical engineering analysis can play a critical role in litigation involving injury causation, liability, and extent of damages, where technical accuracy and scientific rigor are essential. Leveraging decades of combined experience, our biomechanical engineering experts objectively evaluate how forces, motion, and human tolerance may intersect in real‑world events.

We leverage advanced analytical tools, modeling, and state‑of‑the‑art visualization technologies to reconstruct events, assess injury mechanisms, and test the validity of competing theories. Our analyses help legal teams, judges, and juries understand complex biomechanical concepts and equips counsel with credible, defensible insights that inform case strategy and facilitate dispute resolution.

Expert Testimony and Litigation Support

We provide expert witness testimony and litigation support for legal professionals, delivering rigorous, defensible analysis of injury causation and human response to physical forces.

Our experts apply principles of physics, anatomy, and occupant kinematics to evaluate accident dynamics, assess mechanism of injury, and test the consistency of claimed injuries against objective evidence. We are retained by counsel in complex injury and liability matters, developing clear, well‑supported opinions informed by industry standards, peer‑reviewed research, and validated analytical methods.

We prepare expert reports and deliver expert testimony through a “teaching, not telling” approach, effectively translating complex technical and scientific analyses into clear, compelling trial testimony that withstands legal scrutiny.

Industries We Serve

Our biomechanical engineering experts support clients operating in environments where injury risks, product performance, human interaction, and exposure to physical forces are central issues. We deliver objective analysis to organizations and their counsel in sectors including:

  • Aerospace and Aviation
  • Appliances
  • Automotive
  • Consumer Products and Services
  • Food and Beverage

  • Technology, Media, and Telecommunications

Our Biomechanical Engineering Engagements 

Our biomechanical engineering analysis provides legal counsel and insurance professionals with objective, science‑based insight into how an incident occurred, how forces were applied to the body, and whether those forces are sufficient to produce the claimed injuries. 

We collaborate with multidisciplinary experts across our firm – including, accident reconstructionists, human factors experts, forensic accountants, medical billing and nurse consultants, building consultants, and visualization experts – to deliver comprehensive solutions for:

  • Vehicular Accidents
    • Passenger Vehicle, Commercial Vehicle, and Motorcycle Crashes
    • Pedestrian and Bicyclist accidents
    • Rollover Incidents and Low-Speed Collisions
  • Slip, Trip, and Fall Incidents
  • Product Liability and Equipment-Related Accidents
  • Workplace and Industrial Accidents
  • Sports, Recreation, and Personal Injury Incidents
  • Construction Site Accidents
  • Premises Liability Incidents

Motion Capture Services

Our User Experience Research Laboratories (URL) in Phoenix, Arizona, and Redmond, Washington, provide motion capture services to objectively evaluate how the human body moves, loads, and responds during real‑world work activities and product use.

By analyzing posture, repetition, force, and joint mechanics, we help identify musculoskeletal strain, ergonomic risk factors, and injury potential before incidents occur. Our analyses support injury prevention, product design evaluation, and defensible risk management strategies. Leveraging advanced motion capture technology and extensive product development expertise, our experts provide reliable insights that inform safety improvements, reduce risk exposures, and strengthen legal defensibility.
