Paralyzed Man Moves His Hand With the Help of Bionics

Ian Burkhart last felt his hand move in 2010, before he accidentally dived into a sandbar and was paralyzed from the elbows down.  Severed spinal cords are one of the great mysteries of the medical world; without an electric current flowing through the body, the nervous system is useless, and the spinal cord is so specialized and unique, the body can't regenerate cells that can reactivate it.

However Battelle, a non-profit technology research organization, has come closer than anyone to bypassing this problem.  Nick Annetta, an electrical engineer for the group has worked with Ian to reach a breakthrough in medical as well as manufacturing science: creating a bionic apparatus that sends brain signals to a paralyzed limb, successfully moving it.  From the Washington Post:

"...doctors opened Burkhart’s skull. They crowned his head with a small metal cylinder, attached to bone by screws, and ran a wire between it and the chip they stuck like Velcro to his brain.

....The doctors knew the chip was in the right place to pick up the brain signals. The engineers knew their algorithm was translating his thoughts to movements. They believed the film strips strapped around his forearm, which they called a sleeve, would stimulate his muscles to make those movements a physical reality."

Three times a week, Burkhart would practice online with Battelle experts, concentrating on digital "drills" that were essential visualization exercises.  When it became time to try the tech out, Burkhart was able to visualize his hand opening and closing and with the help of the chip in his brain and the sleeve around his forearm, was able to turn his thoughts into motion.
Technology to send electrical impulses to limbs immobilized by spinal cord injuries is rapidly expanding
This is an astounding breakthrough for so many industries.  The medical world may have found a device that can help victims of spinal cord damage become self-autonomous, decreasing the need for expensive round-the-clock care.  The world of neuroscience has inched even closer to harnessing the miraculous possibilities of the brain, and the digital software world has blurred the lines further between computerized and biological thought.  Firms and investors most certainly should take the results of Mr. Annetta and Mr Burkhart's seriously enough to look at how fast the tech can be refined enough for efficiency and cost-effectiveness.  Although the medical aspects are clearly expensive (brain surgery is not getting fit for a dental retainer), the basic concept for the software is quite simple to reproduce, and the training aspects for the patient can only get better as more is learned.  The doctors involved in the experiment speculate as to the future of bionics, bringing up ideas such as portable smart phone apps that would decode and recode the brain signals, instead of a stationary computer system, or wireless chips that would obviously be less cumbersome in practice.

These are all developments that may be down the road, but take this into account: soon after the initial experiment, Burkhart demonstrated the ability to grab a spoon and release it, without any prompt or drills required.  His brain, and the computer, learned faster than anyone anticipated.
