Computer Simulation of Stair Falls to Investigate Scenarios in Child Abuse

Abstract

Computer simulation techniques are useful for investigating the biomechanics of stair falls. Using our simulation model, we determined that stair characteristics have an effect on potential for lower extremity injuries. Although absolute values of biomechanical measures should not be relied on in an unvalidated model such as this, relationships between accident-environment factors and biomechanical measures can be studied through simulation. Future efforts will focus on model validation.

Femur loading in feet-first fall experiments using an anthropomorphic test device

“…26 Computer simulation studies of pediatric falls have shown influence of fall height, surface properties, and impact position on lower extremity loads. 26, 27 Additionally, the increase in lower extremity loads with increasing height seen in this study is consistent with prior ATD studies. 11, 13…”

Stair-Related Injuries to Young Children Treated in US Emergency Departments, 1999–2008

“…6,9 This study identified an estimated 3534 fractures to the humerus and 4527 to the femur. Research shows that femur fractures can occur from falls down stairs under certain conditions, 20,21 such as when a caretaker falls with the child; however, multiple injuries do not commonly result from stair-related falls. 21 Therefore, the presence of multiple injuries warrants more investigation to ruleout intentional injury.…”

Digital games and virtual reality applications in child abuse: A scoping review and conceptual framework

“…It seems that the use of mathematical models as a noninteractive type of computer simulation is a more suitable solution for diagnosing cases of child maltreatment. For example, Thompson and Bertocci (2013) [53], and Bertocci et al (2001) [54] developed computer simulation models to study the biomechanics of pediatric bed fall, and stair falls, respectively. In this study, experts recommended that SGs can be used for questionnaire-based diagnosis of child abuse.…”
