Quick Radar Scan used for Concussion Diagnosis
People with concussions don’t walk normally. Their brain impairment is equivalent to have a blood alcohol of 0.05. The alteration in their gait is more pronounced when they perform cognitive tasks while walking. In April 2011 researchers at Georgia Tech Research Institute demonstrated the use of a simple radar test in the field to diagnose concussions. When people with a concussion walk toward the radar device while saying the 12 months of the year backwards their gait is detectably different on radar than the gait of a normal person. The radar technique is effective and is quicker and cheaper than existing techniques which utilize motions sensors and make people wear reflective markers on their clothes.
