Paralysis occurs when a vertebra or vertebrae become injured within the spinal column. This can imply that the vertebrae may have been compressed, fractured, or even shattered. With the fragile anatomy of the spinal column, various activities can lead to spinal injury. People are at much higher risk for injury if not taking proper precautions or using proper form when dealing with heavy objects. Luckily, not all spinal injuries end up resulting in paralysis of some sort. However, it is essential to prevent the possibility of paralysis so one does not have to use this technology. If the spinal cord does, however, get injured, the electrical signals cannot effectively pass through the fragile nerves. Because these electrical signals aren’t being transmitted, the brain may lose control over some part of the body. Unfortunately, in the United States, paralysis effects around 1.9 million people. Some patients being worse than others, paralysis can sometimes effect the entire body, leaving them immobile. With this new development introduced by Courtine and his team, they are confident that paralysis may soon be an issue of the past.
