In the biomechanics lab at San Diego State, Goble tests his device, called B-trackS. It’s designed to precisely measure an athlete’s ability to maintain proper balance. Balance is one of the things that’s affected when a person suffers a concussion.
As an athlete stands on B-trackS, a squiggly line appears on a computer monitor.
“The green line is a representation of sway, so if he moves right, the line goes right,” Goble says. “If he moves left, it goes left. And so, it’s just tracking how much he sways, and we know that the more you sway, the worse your balance is.”
