Now the second criteria was the levels of injury.
So let's talk about the skeletal level of injury.
That's the vertebra that has the most damage to the bones and ligaments.
So the skeletal level of injury will be the vertebra that has the most damage to the bones and ligaments.
Now, the neurologic level of injury is another level that we look at.
That's the lowest segment of the spinal cord with normal sensory and motor function on both sides of the body.
So we've got the skeletal level and the neurological level.
Now tetraplegia was formerly known as quadriplegia, but you'll hear many people speaking it as tetraplegia now.
It's paralysis of all four extremities.
If you look at the graphic that's why he is green from the neck down, that represents paralysis.
Now, these are from cervical spinal cord injuries, remember those are the vertebra that -
they're very at the top of your spinal cord.
So the degree of arm impairment depends on the level of the actual cervical injury.
So, C4 would likely have relatively less impairment than C3 or higher.
And all is individual, depends on that patient.
But just as a general rule, if I had a C4 injury,
would likely have a little bit less impairment than someone who had C3 which is higher and would be worse.
Paraplegia response - paralysis and loss of sensation in the legs.
So you got it from right across the middle.
The hands may not work very well, also the legs will be paralyzed.
Thoracic, lumbar or sacral spinal cord injuries can end in paraplegia.
Now, how much or how significant the impairment is depends on the actual specific level of the injury.
T6 paraplegia is paralysis below the chest. L1 paraplegia is paralysis below the waist.
So I've got an example for you there.
Looking at the graphic, which level of paraplegia is this? Is it T6 or L1?
Right, it's L1. It's paralysis below the waist.
