Doctors say Rep. Gabrielle Giffords can walk a little and is even trying to improve her gait.
Giffords uses her left side and has begun making limited use of her right arm and leg, a common effect of a bullet wound on the left side of the brain, said Dr. Gerard Francisco, chief medical officer at Houston's TIRR Memorial Hermann who works with Giffords daily.
"Her left side is perfect," said Pia Carusone, her legislative chief of staff. "She can do whatever you can do."
She said that even in her wheelchair Giffords has stringent posture: tall, tight, strong - like always.
Nurse Kristy Poteet said Giffords pushes a cart up and down the hospital halls as therapy, focusing on using the correct muscles. More therapy comes from games of bowling and indoor golf.
An Arizona Republic report - containing interviews over the past few days with her husband, doctors and others close to her - gives the latest picture of her recovery 15 weeks after being shot.

The physicians place her in the top 5 percent of patients recovering from her type of brain injury, the newspaper said.
"She shows a lot more independence right now," Francisco said. "She's her own person."
Giffords' husband, Mark Kelly, told the Republic that his wife longs to leave the rehab center for good, repeating "I miss Tucson." When that day comes, Giffords told Poteet she plans to "walk a mountain."
Dr. Dong Kim, the neurosurgeon who oversees Giffords' care, said most of the physical and speech recovery happens within 12 months.
Those closest to Giffords tell of a woman progressing from severe brain trauma, but their words are without heightened expectations.
She speaks most often in a single word or declarative phrase: "love you," "awesome," those close to her said.
There were hopeful language signs even in March when Kelly said Giffords learned about the people killed during the Tucson rampage Jan. 8.
Kelly said he was reading a newspaper story about her out loud when she noticed he skipped a paragraph. That paragraph told of the casualties in the Tucson shooting - news that set Giffords grieving.
"So many people, so many people," Giffords repeated. Poteet said she would find Giffords with heavy looks on her face, repeating "no-no-no-no-no."
For that reason, Kelly said he hasn't told her that the victims included her friends and colleagues Gabe Zimmerman and Judge John Roll, or a 9-year-old girl, and three others, the kind of older constituents she loves to help.
Kelly said he wants her to be able to process the emotions without fighting so hard for the words.
"The challenge is she knows what she wants to say, and she knows everything that's going on around her," Carusone said, but can't always express it.
