Intro to SCI
A spinal cord injury turns your life upside-down. You go from running around not worried about a thing, to being in a wheelchair unable to walk or worse. It's a hard adjustment that takes a lot of time to get used to.
But why is a tear or a bruise to the spinal cord so serious? The reason - the spinal cord can't fix itself. Unlike a broken bone, a hurt spinal cord does not get better. Like an amputated arm, it cannot grow back. Doctors however are working hard to figure out how to heal it. They're getting close, but they still have a ways to go.
Here are all the ways a body can change when a spinal cord injury occurs:
You may be wondering, why are some people with spinal cord injuries unable to move anything while others can move their arms, but not their legs? It all depends on where the spinal cord the injury happens. The higher it is on your spinal cord (the closer it is to your head) the worse the injury is. And the lower your injury is, the less you'll be paralyzed.
For those who injure their spinal cords in their neck, they're called quadriplegics (definition: paralysis of all four limbs or of the entire body below the neck ). These people sometimes can't move their arms or their legs. Some however can move their arms if their spinal cord is damaged in the neck, the injury is just lower in the neck.
And for anyone who hurts their spinal cord in the back, they're called paraplegics (definition: paralysis of both lower limbs due to spinal disease or injury ). These folks usually can move more. Most can move their arms like normal, their hands and fingers too, but most have no leg movement.
Also, if the spinal cord is torn in two (called a "complete" injury) this is the worst damage you can happen to a spinal cord. Many people with an injury like this can't move or feel anything below their level of injury. If a spinal cord is injured but was not torn in two, you have a much better chance of maybe feeling or moving again (this is called an "incomplete" injury).
