New portable device developed by Georgia Tech and Emory checks for concussions on the sidelines

A player just took a hard knock to the head and is lying on the field. A coach rushes to his side, but the player sits up and seems fine.

He knows who the president is and how many fingers the coach is holding up. But is he ready to get back in the game?

More than 750,000 mild traumatic brain injuries (mTBI) occur in the United States each year. When a player or soldier with even a mild concussion is sent back to the field, another blow to the head can lead to additional life long problems or even second impact syndrome, which has a mortality rate of up to 50 percent. But the injury is difficult to diagnose, even with a quiet room and a several-hour-long test.

Michelle LaPlaca, an assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, and David Wright, assistant director of Emory University's Emergency Medicine Research Center, have developed a new device to detect brain injuries right on the sidelines of a football game, on a battlefield or in the emergency room.

Called DETECT (Display Enhanced Testing for Concussions and mTBI system), the device is a fast, easy to administer and sensitive system for assessing problems associated with concussions. The DETECT device is an integrated system that includes software applications, a portable computer and an LCD display in the headgear.

While a typical mTBI test requires a quiet room and 1-2 hours of testing, DETECT performs neuropsychological tests in an immersive environment in about 7 minutes, regardless of surrounding noise and movement. So, a football player or soldier who just took a hard hit to the head can take the test and either be safely cleared to get back on the field or sent to receive medical attention.

The device blocks external stimuli that could interfere with testing, such as light and sound. This allows the test to be given in virtually any setting, even a bright football field with a roa
