The suit has been created by a team of 150 researchers at the Walk Again Project led by Brazilian neuroscientist Dr. Miguel Nicolelis.
"It's like putting a man on the moon," said Nicolelis. He added that the technology is just the beginning of a future "in which people with paralysis may abandon the wheelchair and literally walk again."
The exoskeleton works by the cap picking up signals from the brain, relaying them to a backpack which contains a computer that decodes the signals and sends them to the legs.
After practice, the brain should start associating the movements of the legs with the vibrations the device makes on the patient's arm, which gives the patient the sensation of having operational legs.
The plan is to have the patient do the symbolic kick-off with one of the official Brazuca balls. The World Cup begins Thursday at 4 p.m. with Brazil vs Croatia.
