About 60% of the Nation’s service members are injured each year, half due to participation in sports, exercise and recreational activities. Approximately 1 million service member medical visits occur each year involving musculoskeletal injuries. 
The Wall Street Journal quotes Colonel Dallas Hack, the Brain Health and Fitness Research Coordinator of the U.S. Army Medical Research and Material Command, “Eighty percent of traumatic brain injuries in the military occur outside of the combat zone, with mechanisms that are similar to those experienced by collegiate athletes.”
The concussion crisis is as pervasive in the military as it is in sport. Dr. Tamara Moreland, Director of Physical Therapy at the Ft. Campbell Wounded Warrior TBI Clinic, has explained that concussions go unreported in the military. Similar to the athlete’s situation, the service member doesn’t want to miss their deployment or risk not being promoted.
TRAZER challenges the service members’s visual, cognitive, neuromuscular/musculoskeletal and cardiorespiratory systems. Its simultaneous measurement of both cardiorespiratory and movement performance assists in determining whether the service member exhibits movement deficits that may potentially place him or her at higher risk of concussion and/or musculoskeletal injury. Reaction time to unplanned visual cues provides a measure of cognitive prowess at progressively higher work rates, which decreases reaction times, thereby improving performance and readiness.
In summary, TRAZER detects movement deficits that may expose a healthy service member to a higher risk of concussion, and conversely, to determine if a concussed service member has fully recovered his motor skills post brain injury.
