Wearable cyborg uses brainwaves to let people walk again

Tokyo (CNN)Kristen Sorensen was 55 when she became paralyzed from the neck down last year.

“It came out of nowhere,” says Sorensen. “I’d been fine and exercising every day, but it just started with tingling in my fingertips then progressed.”
Diagnosed in October 2018 with Guillain Barre syndrome, a rare disorder that affects the body’s nervous system, she never expected to walk again.
    But earlier that year, the Brooks Cybernic Treatment Center in Jacksonville, Florida, became the first US center to use a unique rehabilitative technology developed in Japan — the Hybrid Assistive Limb (HAL).
    HAL — essentially a wearable cyborg — helps those with spinal cord injuries and muscular dystrophy regain their movements and strengthen their nerves and muscles. Known as exoskeletons, they’re a type of lightweight suit, with joints powered by small electric motors, that serve as mechanical muscle.
    Here’s what’s truly mind-blowing: Patients use their brain waves to control them.
    When Sorensen heard about the brain wave-controlled exoskeleton, which was developed by Japanese roboticist Yoshiyuki Sankai, she knew she had to give it a try. She was determined to walk at her daughter’s wedding a few months later in December.
    But it’s not just those with disabilities or injuries who stand to benefit. By 2050, there will be more than 2 billion people over age 60, according to the World Health Organization (WHO), and exoskeletons could offer a solution to the world’s aging population.
    In the future, as human bodies wear down with age, an exoskeleton — powered by active minds — could help people stay on their feet.
    With such huge potential applications available, the global medical exoskeleton market will be worth an estimated $2.8 billion by 2023, according to research company Markets and Markets.

    Tech for good

    The brain behind HAL is bespectacled billionaire roboticist Sankai. He heads up Japanese company Cyberdyne — founded in 2004 — where his vision has been to create these “wearable cyborgs” designed to “fuse man, machine and information.”
    And while the name of Sankai’s firm might recall the scary Cyberdyne Technologies that created villainous robots in US science-fiction blockbuster “Terminator,” the Japanese roboticist wants to create tech not for war, but for peace and rehabilitation.
