TUCSON, Ariz. (AP) — Even Rep. Gabrielle Giffords' doctors are starting to call her recovery a miracle.
Few people who take a bullet to the brain — just 10 percent — survive such a devastating wound.
Yet doctors say the critically injured congresswoman has been making steady progress each day since the assassination attempt on Saturday. Six people were shot and killed.
Mrs. Giffords is moving both legs and both arms, has opened both eyes and is responding to friends and family, doctors said Thursday. They've helped her sit up and dangle her legs from the bed, and she is able to lift her legs.
With her closest friends from Congress holding her hand Wednesday evening, Mrs. Giffords opened her left eye and tried to focus on loved ones for the first time.
"It was raw courage. It was raw strength. It was so beautiful and so moving," said Sen. Kirsten Gillibrand, New York Democrat. "She wanted us to know that she was with us a hundred percent and understood everything we were saying."
Mrs. Giffords' neurosurgeon, Dr. Michael Lemole, called it "a major milestone," and said the congresswoman was clearly responding to the gathering of friends and family.
After five days of pushing for caution, Dr. Lemole said: "We're wise to acknowledge miracles."
The next milestone will be removing her breathing tube, and perhaps have her sit in a chair on Friday, said Dr. Peter Rhee, trauma chief at University Medical Center, who has treated soldiers in Iraq and Afghanistan. Doctors want to make sure Mrs. Giffords doesn't regress and are watching for pneumonia and blood clots.
It's a far cry from Saturday when a shocked nation braced for the worst for the 40-year-old Arizona congresswoman. Several news outlets erroneously declared her dead soon after the shooting rampage that killed six. Stunned by the day's events, crowds held candlelight vigils outside the hospital and Mrs. Giffords' Tucson office.
After her surgery, Dr. Richard Carmona, the former surgeon general and family friend who looked at Mrs. Giffords' brain scans, gave a bleak outlook.
"With guarded optimism, I hope she will survive, but this is a very devastating wound," he said.
But as the days ticked by, doctors shared signs of improvement. There was a glimmer of hope early on: Mrs. Giffords was able to squeeze a doctor's hand in the emergency room.
By Sunday, Dr. Lemole said he was "cautiously optimistic" about her survival. She could follow basic commands when they briefly eased up on her sedation.
Doctors were encouraged Monday that there was no further brain swelling, and Mrs. Giffords could raise two fingers of her left hand and even flashed a thumbs-up.
The following day, doctors said Mrs. Giffords was breathing on her own, but still connected to a respirator as a precaution. She was also moving both arms. Doctors gave their most confident prognosis yet: She will survive.
"She has no right to look this good and she does," Dr. Lemole said.
As her sedation was scaled back, Mrs. Giffords became more alert and moved on her own — touching her wounds and fixing her hospital gown. She even scratched her nose, Dr. Lemole said.
The encouraging news continued when Mrs. Gillibrand and Rep. Debbie Wasserman Schultz, Florida Democrat, stood in the hospital room Wednesday, talking, joking and touching their friend.
"She was rubbing our hands and gripping our hands so ... we knew she could hear and understand what we were saying and she moved her leg, and so we knew she was responding," Mrs. Gillibrand said. "And the more we joked about what we were going to do, she started to open her eyes."
Mrs. Giffords' husband, Mark Kelly, realized the significance of the moment. "Gabby, open your eyes, open your eyes," he said, according to Mrs. Gillibrand.
Said Mrs. Schultz: "It felt like we were watching a miracle."
So how did Mrs. Giffords survive the gunshot wound? The path of the bullet, quick and quality medical care, and a stroke of luck meant the difference between life and death, say her doctors and brain experts.
Doctors think the bullet pierced the front of Mrs. Giffords' head and exited the back, slicing the left side of the brain, which controls speech abilities and muscles on the right side of the body.
Had the bullet damaged both sides of the brain or struck the brain stem, which connects to the spinal cord, the outcome would likely be worse — extensive permanent damage, vegetative state or death.
"So far, she's passed with flying colors of each stage" of her recovery, said neurologist Dr. Marc Nuwer of the University of California, Los Angeles, who is not involved in the congresswoman's treatment.
Most gunshot victims are not that fortunate. Several years ago, a Tucson police officer was shot in the head during a chase. His heart was beating when he was rushed to University Medical Center, but doctors couldn't control the bleeding in the brain and he died, Dr. Rhee said.
When Mrs. Giffords arrived at the hospital, doctors first checked to make sure she didn't have any other injuries. They took a brain scan and wheeled her to the operating room in a swift 38 minutes.
The same attack in the desert many miles away from a trauma center may have led to a different ending.
It's too early to tell the extent of damage Mrs. Giffords suffered, but experts say it's rare for people with gunshot wounds to the head to regain all of their abilities. Damage to the left side of the brain can result in memory loss, difficult reading and hand-eye coordination problems. Mrs. Giffords' doctors have not been able to determine how well she can speak since she still has a breathing tube.
"Her full-time job now for the next year is working on her recovery and rebuilding her life around her disability whatever it may be," said Dr. Stephan Mayer, professor of clinical neurology at Columbia University Medical Center in New York, who has no role in Mrs. Giffords' care.
