According to the article, paralyzed rats have regained mobility by means of chemical and electrical stimulation of the spinal cord. Recent experiments have given rise to much success, there was even an account of this method producing similar results in a human as it has in rats. The process involves stimulating the spinal nerves by injecting specific chemicals into the spine, followed by the electrical stimulation of the base of the cord. Although this is not sufficient to trigger motion, in experiments with rats, with the support of a harness and a treat for encouragement, the injured rats were capable of improving body movement. The key is accessing the brain, the actual desire to move, to enhance the impulse. The success is deemed a profound advancement and a sign that research is heading in the right direction. Until several successful trials are completed it is wrong to falsely give hope to those who suffer from paralysis, but based on the path science has taken, we will likely see further improvements to the technology and the success of its application in our future.
