To perform computational simulations repeated shakings of infant head-brain structure using FiniteElement Method.
Shaken baby syndrome is a form of head trauma that affects the nervous system of infants under the age of 5. This trauma is the result of criminal abuse caused by the violent shaking of an infant’s head by thrusting the child back and forth by the chest or shoulders
Head trauma has been studied extensively using computational simulations, mostly to support automobile crash testing studies. The role of the simulations are two-fold – firstly, they are useful in understanding the mechanisms of injury by “computationally testing” a range of possible scenarios, secondly, they are very useful for designing safety equipment, automobiles etc. to meet required standards that will protect operators. Hence, regulatory bodies like the NHTSA have created a range of validated Finite Element brain for use by automobile manufacturers and other equipment manufacturers in their safety testing . However, these studies typically involve single event impact type closed-head trauma of adult head models. These models are not appropriate for the analysis of SBS since the head/brain models used have significantly different head and neck structures from infant models. Further, Shaken Baby Syndrome is typically the results of a succession of thrusts back and forth over time scales ranging up to few seconds while most head trauma studies have focused on loadings no longer than a few milliseconds.
