Insights
Investigating child abuse indicators, this study simulated falls using a pediatric test device. Findings show bruises from falls typically appear on the head and torso
Area of Science:
- Pediatrics
- Forensic Science
- Biomechanics
Background:
- Unexplained bruises in children can indicate physical abuse.
- Bruise location helps differentiate abusive from accidental trauma.
- Limited data exists on bruising from falls in children.
Purpose of the Study:
- To predict potential bruising locations from simulated falls in children.
- To analyze impact sites during rearward falls using a pediatric test device.
Main Methods:
- A 12-month-old pediatric anthropomorphic test device (ATD) with force-sensing skin was used.
- Simulated rearward falls were conducted onto carpet and tile surfaces.
- Impact data was mapped onto a computerized body image.
Main Results:
- Impacts, and potential bruising, were concentrated on the occipital head and posterior torso.
- Fall simulations identified specific posterior body regions at risk for bruising.
Conclusions:
- This research provides data on expected bruising patterns from falls in young children.
- Findings can aid in distinguishing accidental falls from physical abuse in pediatric cases.
Abstract:
Children presenting multiple unexplained bruises can be an early sign of physical abuse. Bruising locations on the body can be an effective indicator of abusive versus accidental trauma. Additionally, childhood falls are often used as falsely reported events in child abuse, however, characterization of potential bruising locations associated with these falls does not exist. In our study we used a 12-month old pediatric anthropomorphic test device (ATD) adapted with a custom developed force sensing skin to predict potential bruising locations during rearward falls from standing. The surrogate bruising detection system measured and displayed recorded force data on a computerized body image mapping system when sensors were activated. Simulated rearward fall experiments were performed onto two different impact surfaces (padded carpet and linoleum tile over concrete) with two different initial positions (standing upright and posteriorly inclined) so that the ATD would fall rearward upon release. Findings indicated impact locations, and thus the potential for bruising in the posterior plane primarily within the occipital head and posterior torso regions.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
