The former Team USA Olympic high jumper who was paralyzed in a training accident in California last month says he's making HUGE progress -- and can now move his arm!!!
As we previously reported, 2-time Olympic high jumper Jamie Nieto fell on his head while training Olympic hopefuls last month ... and suffered major damage to his spinal cord.
But in a new video shot from his hospital bed, the 39-year-old said he's "getting better every day. Just feeling a lot better."
Nieto -- who underwent emergency surgery following the life-threatening accident -- is also trying to walk again .
