This Exoskeleton Could Help Stroke Victims Walk
Ekso Bionics has just received clearance from the FDA to market a bionic exoskeleton for use in the treatment of stroke and spinal cord injuries, according to a press release from the robotics company. Although there are at least two other robotic exoskeletons already on the market, the Ekso GT is the first to receive explicit FDA approval for rehabilitating stroke patients—a major coup for the company.
“This clearance marks a major milestone towards our goal of establishing exoskeletons as standard of care in the rehabilitation clinic,” said Thomas Looby, president of Ekso Bionics. Looby adds that he hopes that the announcement, “will translate into broader adoption of exoskeletons by hospitals and rehabilitation clinics and better outcomes for patients.”
Ekso is not the only robotic exoskeleton on the market. ReWalk and HAL, two other prominent exoskeletons that have already enjoyed their share of successes in the burgeoning bionics industry, even have some advantages over Ekso.
ReWalk, produced by Argo Medical Technologies, was actually the first exoskeleton to gain FDA approval, back in 2014. While the suits cost a prohibitive $70,000, they are already helping some paralyzed patients to walk again, with motion sensors and motorized joints that can detect and adjust to subtle changes in upper body movement. HAL, produced by Cyberdyne, is even more sophisticated, with sensors that attach to a patient’s skin and pick up the weak signals that the brain is sending to the unresponsive, paralyzed limbs.
But Ekso captured our hearts with the touching story of Mark Pollock, who became the first person with complete paralysis to actively work with a robotic device to walk again. Since Ekso includes a computer system that tracks motion while employing spinal stimulation, the device was able to collect data on Pollock’s movements as he began to actively assist the robot, flex his knee and raise his leg, all by his own power. And that’s the real hope for the future—baby steps toward an exoskeleton that could one day cure paralysis.
