OBJECTIVE Mild traumatic brain injury (mTBI) accounts for more than 75% of traumatic brain injuries every year. This study examines the temporal association between non-blast mTBI and the onset of neurologic sequelae to illuminate risks of post-concussive syndrome, epilepsy and chronic pain. METHODS A large historical prospective study was conducted(More)
In large-scale computer simulation models it is often neeessary to perform a screening experiment to reduce the number of factors to be examined in subsequent analysis. This study evaluated the results of a Plackett-Burman screening design using three different analysis strategies: 1) an approach due to Box and Meyer (1993); 2) an approach due to Hamada and(More)
OBJECTIVE Military personnel are at increased risk for traumatic brain injury (TBI) from combat and noncombat exposures. The sequelae of moderate to severe TBI are well described, but little is known regarding long-term performance decrements associated with mild TBI. Furthermore, while alcohol and drug use are well known to increase risk for TBI, little is(More)
BACKGROUND Little is known regarding long-term performance decrements associated with mild Traumatic Brain Injury (mTBI). The goal of this study was to determine if individuals with an mTBI may be at increased risk for subsequent mishaps. METHODS Cox proportional hazards modeling was utilized to calculate hazard ratios for 518,958 active duty U.S. Air(More)
