The purpose of this study is to develop the method to distinguish child abuse from accident injury by using anthropomorphic test dummy. In this study, shaking assumed child abuse and falling events assumed unintentional injury were examined. As the experimental conditions, two posture of shaking and gender difference in shaking were defined to clarify these effects on head injury risk outcomes. And also, four fall heights and three surfaces for falling were examined. Subdural hematoma (SDH) and skull fracture were evaluated by the peak change of angular velocity and HIC, respectively. As the result of experiments, shaking events cause SDH due to higher peak change of angular velocity, which exceeds the tolerance value, than the case in fallings. Moreover, both the shaking posture and gender affects greatly on the peak change of angular velocity. On the other hand, falling events cause skull fracture because of the higher HIC value than shaking cases.
