Effects of Mild Traumatic Brain Injury (Sports-related Concussion) on Eye-head-hand Coordination
Despite the prevalence of mild traumatic brain injuries (sports-related concussions are estimated to occur over 3.5 million times annually in the U.S.), prevention, identification, treatment, rehabilitation, and determination of recovery time-points are largely inadequate due to the paucity of parametric factors that can be easily and reliably measured both in the field and in the clinic. We have designed a battery of visual-spatial tasks that require coordination of the eyes, head and hand and address sensorimotor plasticity, spatial working memory, and orientation in order to identify parameters that reliably track behavioral markers of mTBI. Current work in the lab is focused on effects of mTBI and of normal aging on eye-head and hand coordination in human subjects. Using techniques developed during our earlier work (see below) to characterize changes in coordinated visual orienting behaviors.
