Spinal cord injuries / paralysis are fatal because they cut the communication between the brain and extremities - damaged nerves can not transfer signals from the brain to the limbs, making them unusable. However, recently, a team of scientists from Ohio State University and Battelle partnered to use an innovative technology called Neurobridge (created by Battelle) that helps quadriplegics move their limbs with just their thoughts!
Ivan spotted wearing Neurobridge technologyAs mentioned above, the nerves are crucial to the movement of the limbs and fatal accidents that cause injury to the
spine and nerve damage drastically affect limb movement. This is where Neurobridge comes to rescue. A small chip (smaller than a pea) is implanted in the part of the brain that controls movement of the arm and hand. This chip reads and interprets brain signals, sends them to a computer that sends them to recode and a sleeve that the patient is using, and simulates the appropriate muscles, allowing them to move the desired end. A total of one tenth of a second of thought in limb movement is needed. So essentially, it fails completely (damaged) nerves responsible for transmitting signals from the brain to the limb and sent directly to the muscles instead.
This remains a clinical study (approved by the FDA) which is working with five patients. Currently, the study focuses on the arms and hands, but the future possibilities are endless. To begin brushing, flossing, using their hands to eat with a spoon or fork, etc can be a big boost to the morale and confidence of a paralyzed person.
What scientists have achieved so far is a big step forward, and only going to continue doing this kind of progress in the future.
