Mark Muhn is used to watching from his wheelchair as his kids win trophies for their achievements on the sports field. He’s been in that wheelchair since 2008, when a skiing accident crushed his spine and left him paralyzed from the chest down.
Last Saturday, though, Mark was the one on the podium with a gold medal draped around his neck. “I’ve watched my kids win, but this time they got to watch me,” he says.
Muhn won gold at the Cybathlon, the world’s first cyborg Olympics, which took place this weekend in a sold-out stadium in Zurich, Switzerland. He competed in a bike race that required the human body and cutting-edge technology to work in tandem. During the race, implanted electrodes sent pulses of electricity into the nerves in his legs to control his dormant leg muscles. With the right pattern of electrical pulses, his paralyzed legs pushed on the bike pedals. [Scroll down for video.]
“You could really see the technology and the pilot working together,” says neural engineer Ronald Triolo, who developed Muhn’s gear as a researcher at the Advanced Platform Technology Center at the VA Medical Center in Cleveland, Ohio. “The total was greater than the sum of its parts.”
