"It sends a stimulation to the appropriate nerve to help them pick up the foot to give them a normal gait pattern when they walk," said Brian Karban, an orthotist at Hanger Prosthetics and Orthotics.
The device, about the size of an iPod, is strapped around the calf, and a gentle electric signal is sent from the device to the leg, telling the foot to lift and lower.
The WalkAide helped regenerate communication between Gomez-Trost's brain and her foot.
"When I first put it on all I could say was awesome, awesome," she said.
Without the WalkAide, Gomez-Trost limped along with the help of a cane. Using the device, she is able to climb stairs with no visible limp.
