## Abstract

SUMMARY
In the US, there are more than four sports-related traumatic brain injuries every minute. Sports-related
concussion (SRC) in youth has received heightened attention due to emerging evidence that SRCs can affect
academics, behavior, and neurocognitive processes, such as working memory, concentration, processing
speed, and eye and motor function. A recent Institute of Medicine report on SRCs in youth revealed how little is
known about concussion in the young brain, and called for urgent attention to determine the incidence of SRCs
in boys and girls by sport and demographic; research to identify unbiased, sensitive prognostic and diagnostic
metrics/markers; longitudinal studies to determine outcomes; and to delineate age- and sex-related
biomechanical determinants of injury risk. This innovative hypothesis-driven Bioengineering Research Grant
will generate objective diagnostic tools for use in concussion (Aim 1), new technologies to translate human
outcome metrics to animals to provide a human-like platform to develop and test injury treatments in the future
(Aim 2), and new knowledge regarding high-risk sports settings for youth (Aim 3) that will drive safety
equipment design. The most innovative feature of the study is the integration across Aims to use BOTH male
and female high school students and piglets in a deliberately parallel study design to determine optimal SRC
assessments and identify mechanistic relationships between sex, loading conditions, and SRC symptoms. The
integration of human and animal studies which employ similar neuro-functional assessments leverages the
strengths of each approach: human studies ensure the study of biofidelic physiologic processes, and animal
studies allow application of specific loading conditions and outcomes not easily measured in living humans,
such as neuropathology. Extensive pilot data establish feasibility and sample sizes in all Aims. In Aim 1 an
unbiased numerical assessment suite for SRC will be developed and independently validated to establish
≥95% sensitivity, and determine if these metrics are predictive of days-to-clearance for sports. Because the
Aim 1 objective metrics are nonverbal and effort-independent, they have been “translated” to animals and
reveal human-like physical, cognitive, and sleep symptoms of SRC in animals after rapid controlled head
rotations. In Aim 2, single head rotations and multiple sub-concussive rotations are computationally scaled
from teens to an immature large animal model of mild TBI, to identify the effects of sex and load frequency,
magnitude and direction on neuro-function, biomarkers and neuropathology. Aim 2 will identify biomechanical
settings of greatest risk for the young brain. The biomechanical insights from pigs in Aim 2 are translated to
teens in Aim 3, where head impact sensors are used to quantify biomechanical load exposure by sport and sex,
and the relationships between load exposure and neuro-functional metrics. The proposed studies in an...
