In an historic move, the VA has agreed to pay for robotic
legs for eligible paralyzed veterans with spinal cord injuries. The powered
exoskeleton, called the ReWalk, was approved for in-home use by the FDA in 2014,
but the $77,000 price tag meant few insurers would cover it.
The device consists of leg braces with motion sensors and
motorized joints that can respond to changes in upper body movement and shifts
in balance. There is also a computerized control system and a tilt sensor. Worn
outside the clothing, there is a support belt around the waist to keep the suit
in place as well as a backpack for the computer and rechargeable battery.
Crutches must be used for stability, and FDA regulations require that an
assistant be nearby.
The ReWalk not only improves quality of life, but also
provides additional health benefits. VA pilot studies show that paraplegics who
used the device as little as four hours a week for three to five months saw
improved bladder and bowel function, improved sleep, less fatigue, and decreased
back pain. Research into the long-term effects and benefits of this device are
ongoing.
The ReWalk is not for everyone, however. It does not work
for quadriplegics due to the need to use the arms and upper body with the
device. There are also very specific weight and height requirements.
The VA has started training staff at twelve healthcare centers
to provide the system, and the program is expected to expand. Already, 45
paralyzed veterans have been evaluated and meet the requirements for the
device.
