Risk functions for human and porcine eye rupture based on projectile characteristics of blunt objects.

Eye ruptures are among the most devastating eye injuries and can occur in automobile crashes, sporting impacts, and military events, where blunt projectile impacts to the eye can be encountered. The purpose of this study was to develop injury risk functions for globe rupture of both human and porcine eyes from blunt projectile impacts. This study was completed in two parts by combining published eye experiments with new test data.

Material properties of human rib cortical bone from dynamic tension coupon testing.

The purpose of this study was to develop material properties of human rib cortical bone using dynamic tension coupon testing. This study presents 117 human rib cortical bone coupon tests from six cadavers, three male and three female, ranging in age from 18 to 67 years old. The rib sections were taken from the anterior, lateral, and posterior regions on ribs 1 through 12 of each cadaver's rib cage.

Thoracic and lumbar spine accelerations in everyday activities.

The purpose of this study was to quantify thoracic and lumbar spine accelerations for men and women of different body sizes during daily activities. Measured spine accelerations were compared to determine if there were significant differences in peak accelerations based on gender, size, and spine location. Each subject performed seven activities, which included sitting in a chair, sitting quickly in a chair, walking at 1.

The effect of gender and body size on linear accelerations of the head observed during daily activities.

The purpose of this study was to determine the effect of gender and body size on peak linear head accelerations during daily activities. Head accelerations were measured for 18 volunteers using a biteplate system. Each subject performed seven activities: sitting in a chair, sitting quickly in a chair, walking at 1.

Evaluating eye injury risk of Airsoft pellet guns by parametric risk functions.

Over 2.4 million eye injuries occur each year in the United States as a result of trauma. New toy guns, commonly referred to as Airsoft guns are increasingly becoming responsible for ocular injuries in children.

Determination of significant parameters for eye injury risk from projectiles.

Background: Eye injuries affect a large proportion of the population and are expensive to treat. This article presents a parametric analysis of experimental data to determine the most significant factors for predicting ocular injuries or tissue lesions.

Methods: Using logistic regression, statistical values were generated to determine significant projectile characteristics for predicting ocular injury in published studies.
