Medical care providers, social services, and legal systems are needed to make critical decisions regarding child abuse however the diagnosis is difficult because the differential diagnosrelys on individualized experiences, and empirical data. Especially, although, subdural hematoma is one of the commonest features of the abused children, the mechanism is unknown. We constructed an infant anthropometric dummy that had a realistically shaped physical model of an infant head to help visualize and clarify the mechanism of acute subudural hematoma during shaking or falling accident. Intracranial brain motion during shaking was more significant than the case in falling because significant reverse rotational motion between the skull and brain occured during shaking. Therefore, the risk of acute subudural hematoma in shaking was significantly higher than the falling situation.
