Simbex Press Release

Lebanon, NH - July 6, 2005 - Simbex LLC, a world-renowned research and development company and developers of the Head Impact Telemetry™ (HIT™) System, announced that its HIT™ System will be used in a study to evaluate Mild Traumatic Brain Injury (MTBI) in women athletes.

Researchers from the Wayne State University Department of Biomedical Engineering, major contributors to the Federal Motor Vehicle Safety Standard (FMVSS), Federal Aviation Administration (FAA) standards and the National Highway Traffic Safety Administration (NHTSA) standards on the subject of head trauma, are leading an important study funded by NOCSAE into the risks of sports-related MTBI for female athletes. Of the many studies that have been done on the subject of the biomechanics of MTBI, all have focused on male athletes. No studies have ever been published that specifically focus on the biomechanics and risks to women of MTBI in sports.

Boxing provides an ideal, impact-rich, supervised activity for MTBI research. The study will include one hundred amateur boxers (fifty male and fifty female) of varying skill and weight class. The boxers will be pre-tested to assess their motor, sensory, coordination and cognitive abilities and certain bio-chemical levels to establish baseline levels before a competitive bout (four, two minute rounds maximum). The athletes will be retested directly after the fight and following a 24-hour period of rest to measure any changes of those parameters.

The HIT™ System will be used to measure the impacts to the head during each competition. The peak impact magnitudes, the number of impacts, the locations of the impacts and a history of the cumulative impacts are measured and written to a permanent database. A rolling history of physiological and cognitive assessment measures can be compared to the corresponding history of head impacts to search for relevant correlations and connections. "A study like this could lead to a better understanding of the biomechanics of MTBI, and it would not have been practical before the HIT™ System technology became available. We just didn't have the ability to measure the magnitude and character of impacts for such a large group," said Marianne Wilhelm, PhD, the principal investigator from Wayne State University.
