Our Biomechanical experts can determine the cause of the trauma and its relationship to the injury based upon environmental conditions, incident dynamics, and medical diagnosis.


Biomechanical Engineering applies the principals of mechanical engineering to the study of the human body.  This includes human anatomy and physiology specifically relating trauma to injury.  Forensic biomechanics focuses on a person and their interaction with the environment to determine whether the interaction caused injury in matters involved in litigation.  We are able to determine the mechanism of injury based on medical records and environmental conditions to validate or contest a claim.  We can also review the mechanical aspects of a product and the product’s interaction with the human body to assess if a product was properly designed and utilized.  At CESI our professionals are also able evaluate difficult and unusual cases in which the causation of the injury or the dynamics of an incident is not completely understood.  With our 3-D scanning capabilities, we are able to render rooms and environments with precision to enable accurate representation of accident mechanics and environments.

Accident Reconstruction

From low speed rear end collisions to high speed rollover incidents, our experts can analyze all aspects of traffic accidents, including occupant dynamics as they relate to injuries and reconstruction of the vehicle dynamics.  We can determine the occupant kinematics, how injuries occur within a vehicle, and evaluate restraint systems and protective devices to establish if they function properly and if the injuries are consistent with the incident circumstances.

Amusement Park Accidents / Safety

Although precautions may have been taken to ensure safety, there are still times when an incident involving injury occurs at an amusement park.  We have extensive experience with amusement park incidents.  From the guarding of a ride to the interaction of the patrons with the ride, our experts can assess the functionality of the rides and the reasonableness of the safety parameters.

Biomedical Engineering

When injuries involving medical products and devices occur, we have the ability to investigate and evaluate this type of case.  The devices can range from infusion pumps and oxygenators to vascular and orthopedic devices.  We have expertise in the design, approval, implementation, and application of a variety of biomedical devices that are used in clinical settings.  In addition, we can evaluate pharmaceutical delivery system parameters and safeguards.

Bodily Injury

Bodily injuries can happen in many different circumstances.  Using the mechanics of the body and it’s interaction with the environment, we can determine the means in which injuries were incurred.  With this process we can conclude, if the injury occurred in the manner reported.

Occupant Biomechanics

Occupant Biomechanics are helpful in relating the application of mechanical engineering to occupant injury.  Our experts can determine occupant movements and the injury mechanics by using the vehicle damage and dynamics, injury location, cabin deformation and the nature of the injury.

Playground Accidents / Safety

Playgrounds are constructed in many different ways and fitted with various types of recreational equipment for public use.  We have certified playground inspectors that can analyze playground design for compliance with existing safety standards as well as analyze how the injuries occurred.

Slip, Trip & Fall

When a slip, trip or fall occurs, our experts can analyze the mechanics of the incident to determine whether the built environment was a cause or factor.  The examination of the incident site and/or documentation of the incident site conditions are used to determine whether a hazard was present.  We can evaluate design, construction, and maintenance practices that may be applicable to the incident location.  When applicable, slip-resistance testing of the walking-surface can be performed to establish whether the walking-surface reasonably complied with codes, standards and practices, and the interaction of the incident footwear with the walking-surface can be evaluated.

Unusual Accidents

At times, an accident occurs that is beyond the normal scope of personal injury.  Our experts have extensive experience analyzing unusual and uncommon incidents and accidents. Understanding the environment and how the human body can react to that environment, along with the injury location, our experts can reconstruct accidents resulting from unusual circumstances to determine their nature and cause.
