Electrical Pulses Help Paralyzed Patients Move
"Four people who were paralyzed below the waist for more than two years were able to voluntarily wiggle their toes and flex their legs, thanks to a promising study that some are heralding as a breakthrough in spinal-cord-injury treatment."
And four years later…
From Wheelchairs to Walkers
"These data leave big questions about what's next. These are just case studies, really, the lowest level of medical evidence. More rigorous studies will be needed. And it's not clear at all exactly why this worked, or how, or, most importantly, who will benefit most. "Now I think the real challenge starts, and that’s understanding how this happened, why it happened, and which patients will respond, says Kristin Zhao, Ph.D., co-principal investigator and director of Mayo Clinic’s Assistive and Restorative Technology Laboratory, in a prepared statement.
Better medical devices will be needed in order to run larger studies, says Louisville's Harkema."The hurdle is the technology," she says. "The technology is just off the shelf for pain. It's not designed for this use." The next step, she says, is for Medtronic or another device company to design a device that is adapted for treating spinal cord patients.
"This tells you there is hope in the future," says Mushahwar. "The technology is developing, and it is developing at a faster rate than you would expect."
They’re not ninjas yet but this is amazing, isn't it?
