Spinal cord injuries are among the most devastating and life-changing injuries
a person can sustain. They happen in an instant - a car accident, a bad
football tackle, a fall on a wet floor - and suddenly one's world
is permanently altered. Often, the injury isn't even the victim's
fault but the result of the negligence of another person. It's a situation
that many have difficulty accepting and adapting to.
Unfortunately, medical bills often come hand-in-hand with the spinal cord
injury. Add to this the costs of therapy, the value of lost wages and
the difficulties in maintaining one's career after the accident, and
the financial damage caused by the injury can be substantial.
Despite all this hardship, many people suffering from
paralysis never give up hope that they will someday walk again. And thanks to a
California company, that dream has come true for one woman.
The woman was paralyzed from the waist down after a skiing accident 21
years ago. Although she can no longer use her legs, she still undertook
therapy to keep them strong, in the hopes that someday the technology
would exist that would allow her to walk. Then, in 2010, she got a call
from engineering firm called Berkeley Bionics asking her to test out a
new form of bionic legs.
The 50-pound exoskeleton is designed to copy the natural gait of human
beings. While wearing the device, the woman found she was able to walk
- slowly, and with difficulty, but definitely walking.
The device works by reading the movement of the user's hips. When the
user shifts his or her right hip forward, the device senses the motion
and takes a step with the right foot. The device has learning capabilities
that allow it to adapt to each specific user's motions. Balance is
assured with a walking stick in each hand.
Unfortunately, the device does have some limitations. It requires the assistance
of a therapist to use it safely, and it requires a fair amount of training
and effort to use. Even so, for the woman who hasn't been able to
walk in 21 years, it's a dream come true.
