And the other is becoming paraplegic.

Or if you're a paraplegic like I've visited the folks at Berkley Bionics they've developed eLEGS.

I took this video last week. Here's a paraplegic patient actually walking by strapping on these exoskeletons.

You're what we call a partial paraplegic, and you'll have all of the injuries that go along with that.

And I don't imagine that you will realize this when you look at this photograph of him, but he's paraplegic.

For those who have disabilities the paraplegic there's the era of brain computer interface, or BCI, where chips have been put on the motor cortex of completely quadriplegic patients and they can control a curser or a wheelchair or, eventually, a robotic arm.
