Biomechanics

Biomechanics is a subspecialty of biomedical engineering that unites the fields of physics and engineering with human anatomy and physiology to study the effects of force on the human body. ARCCA biomechanical experts use generally accepted scientific principles to evaluate injury causation. A causal assessment by a medical doctor typically does not consider the forces of an event and therefore cannot truly opine on injury causation. Biomechanics eliminates such incomplete assessments and relies on well-established principles to perform a thorough scientific evaluation of an event.

Brain Injuries: ARCCA’s biomechanical experts have considerable experience in the cause and prevention of the full spectrum of traumatic brain injuries (TBI). Whether the TBI is diffuse or focal, our experts are skilled at determining the mechanism of injury and evaluating the mechanism(s) in the context of a specific event.  We provide this service to various clients and organizations seeking to evaluate and/or mitigate brain injuries. ARCCA’s biomechanical experts continue to conduct research and testing with respect to various causative factors and mechanisms for brain injury.

Spinal Injuries: Spinal injury mechanisms are well-defined in the scientific community and are dependent upon direction and magnitude of forces applied to the human body.  Understanding these injury mechanisms enables the ARCCA biomechanical expert to determine injury causation. For example, to establish a causal relationship between an event and an intervertebral disc herniation, the spine has to be exposed to significant compressive and bending forces.

Fatal Injuries: ARCCA biomechanical experts use their skills to evaluate a specific set of circumstances to identify where the fatal trauma occurred. For example, in an automotive accident with multiple impacts to a vehicle that resulted in fatal injuries to an occupant we can identify where in the sequence the fatal injuries were created and what causative factors led to the fatality.

Soft Tissue Injuries: Rather than diagnosing soft tissue injuries, our biomechanical experts focus on how such an injury could occur and specifically look at the nature of the forces required to cause a mechanism for such an injury.  They evaluate the available evidence for the possibility of a causal link between the diagnosed injury and a specific event. This assessment is determined by gathering data from testing under a variety of conditions.

Orthopedic Injuries: Injuries to the shoulder and knee joints can be associated with direct blunt trauma or induced through indirect loading. For example, rotator cuff trauma is a result of indirect loading through the arm into the shoulder joint. Alternatively, a clavicle fracture can be the result of sudden blunt force trauma to the shoulder joint. Such orthopedic injuries can be assessed by an ARCCA biomechanical expert to evaluate the possibility of a cause-and-effect relationship.
