 U.S. Rep. Gabrielle Giffords’ condition is improving at Memorial Hermann-Texas Medical Center, but officials at the Houston hospital did not provide any updates on the building of fluid in her brain, according to a statement issued on Sunday afternoon. 
  
 “Her rehabilitation will continue in the Neuro ICU until her physicians determine she is ready for transfer to TIRR Memorial Hermann,” the hospital said Sunday on its website. 
  
 On Saturday, one of her doctors said a buildup of fluid in Giffords' brain likely will keep her in intensive care until at least the end of this week, delaying the start of full-fledged rehabilitation. 
  
 Dr. John Holcomb, a trauma surgeon and retired Army colonel, said doctors would have to decide whether a catheter draining the fluid can be removed and Giffords can be transferred to The Institute of Rehabilitation and Research (TIRR), or if a permanent shunt needs to be inserted. 
  
 "No one expects her to go rapidly to TIRR," said Holcomb, also vice chair of surgery and chief of the acute-care surgery division at the University of Texas Medical School at Houston, Memorial Hermann's academic partner. "We just have to wait and see if the fluid buildup issue resolves itself." 
  
 Holcomb said the fluid buildup was down a little Saturday and doesn't appear to be infected. 
  
 He said Giffords was a little more alert and responsive Saturday, the day after she was flown from Tucson to Houston and two weeks after a gunman shot her and 18 others, six fatally, as she met with a crowd of constituents. 
  
 The bullet entered at the left side of Giffords' forehead and exited the back of the skull, damaging some tissue but missing large portions. 
  
 Holcomb described Friday's trip from Tucson to Houston as "stressful" for Giffords. 
  
 Some therapy in ICU 
  
 Doctors at University Medical Center in Tucson inserted the catheter on Tuesday after fluid collection showed up in a CT scan. 
  
 Doctors didn't publicly mention the issue until Friday, when Houston doctors said Giffords couldn't be moved to TIRR with the drain in place. She could be transferred with a permanent shunt. 
  
 Giffords is undergoing therapy in the ICU, but it is greatly limited compared to the options at TIRR, one of the nation's top brain rehabilitation centers. 
  
 Dr. Gerald Francisco, TIRR's chief medical officer who is working with the congresswoman at the trauma center ICU, said Saturday's therapy consisted of Giffords sitting, standing and moving in bed. 
  
 He said she responded well, able to pick up her leg and put it on the bed, for instance, when instructed. 
  
 An abnormal collection of cerebrospinal fluid, a watery-like substance in which the brain floats, is not uncommon after trauma, said experts, either immediately or for many days later. 
  
 Though it's often just a temporary setback, they said there's no rule of thumb to know when it will resolve itself and in what cases a permanent shunt is required. 
  
 "It's not unusual to keep a drain in for two weeks," said Dr. Ray Sawaya, chairman of neurosurgery at Baylor College of Medicine and UT M.D. Anderson Cancer Center. "You prefer to wait as long as you can before deciding to put in a permanent shunt — that's a lifelong commitment — but the risk of infection goes up exponentially the longer a catheter is in." 
  
 No risk for travel 
  
 Brain trauma experts did not think it was unusual that Giffords was transferred from Arizona to Texas before the issue was resolved, noting that fluid collections can occur suddenly and don't cause travel risks if the patient is otherwise stable. 
  
 Plans to fly Giffords to Houston to rehab at TIRR were finalized Wednesday, the day after the catheter's insertion. 
  
 Holcomb said he thought Giffords' husband, Mark Kelly, a League City astronaut, and other family members were eager to have the congresswoman closer to Kelly's home. 
  
 Indeed, Kelly tweeted Saturday night that Giffords was "Doing great in her new room. Lots of rehab with TIRR staff tomorrow."

 Just a couple of decades ago, rehab was little more than physical therapy for shuffling stroke victims and wheelchair-bound quadriplegics, a last resort after doctors had done all they could. 
  
 Now it's a sophisticated science at the forefront of treating people like Giffords, who was shot in the forehead two weeks ago while meeting constituents in Tucson. An early start on rehab is key to limiting permanent damage, and the Houston hospital where she will be treated uses high-tech tools to push the brain to rewire itself. 
  
 The Arizona congresswoman arrived Friday at the Texas Medical Center, where she is expected to spend a few days in intensive care before moving to TIRR Memorial Hermann rehab hospital. Dr. Gerard Francisco, the hospital's chief medical officer, said Saturday that she was "even more alert today" and progressing nicely with therapy. 
  
 Instead of doctors making you well, rehab means "teaching you how to help yourself" to get your life back, said Dr. William Donovan, a former medical director of the rehab hospital who still works there part-time. 
  
 It's frustrating when your muscles and mind won't work the way you want them to. Emotional challenges, post-traumatic stress and physical problems like seizures, headaches and infections loom as risks that could complicate her recovery. 
  
 No one can predict how she will do, or what her "new normal" will be, as the hospital's CEO, Carl Josehart puts it. A CT scan on arrival showed "really minimal" injury for the mortal wound she had, said Dr. Dong Kim, neurosurgery chief for University of Texas Health Science Center. 
  
 The type of bullet, its path, good trauma care and her general health before the injury bode well for her, but "a bigger impact on recovery is the amount of family and social support after the injury," said Mark Sherer, a neuropsychologist at the rehab hospital. 
  
 After doing a head-to-toe mapping of her injuries and abilities, "we'll have to figure out how to meet each and every deficit," Francisco said. 
  
 The first step: setting a goal, such as being able to live independently or to return to work or school. 
  
 "We try to tailor that to what's realistic," Josehart said. 
  
 His hospital is a modern, six-story, red-brick building with hacienda-style arches and signs with the "O" in Memorial Hermann made into a hopeful yellow sunburst. The rooms are standard hospital ones _ no VIP suites, the doctors quip. 
  
 A large gym can treat 30 to 40 patients at a time with state-of-the-art equipment. There are therapy pools, treadmills with harnesses to help support weight and sophisticated recumbent bikes that send electrical signals to help muscles move. 
  
 A day's stay costs several thousand dollars, and the hospital treats a mix of public insurance, private pay and uninsured patients. About two-thirds have brain injuries _ everything from gunshot wounds to strokes _ and most of the rest are spinal cord injuries. 
  
 "In the early days of rehabilitation _ 20, 30 years ago _ it was not uncommon for patients to be in a rehab hospital for a year," Josehart said. 
  
 Now, three to six months is a very long stay, partly due to better treatments and new technology that allow more care to be given at home _ portable lifts to help people out of wheelchairs, for example. 
  
 How does someone get better in rehab? 
  
 "Practice, practice, practice, and I'm not being facetious," said Dr. Paul Schulz, a UTHealth neurologist who works at the hospital. 
  
 A patient having trouble speaking _ as doctors suspect Giffords might _ could be given a Ouija board and asked to form words on it. Or encouraged to sing what they are trying to say to a familiar tune like the ABC's or Happy Birthday while tapping their fingers, said Dr. David Lacey, medical director of rehab services at Wake Forest University Baptist Medical Center. 
  
 That engages more body systems and encourages new connections and nerve growth, he explained. 
  
 "Sometimes you can break through the speech deficit by using the auditory pathway. They can get the word out rather than just thinking of the word and saying it," said Lacey, who is not involved in Giffords' care. 
  
 At the Houston hospital, therapists sometimes test cognitive function by showing patients the word "red" written in blue, and ask them to read the word. Impaired people often say "blue," distracted by the color, and that can signal the need for training like flash card drills, Schulz said. 
  
 "You have to do it with a lot of empathy because you don't want to frustrate the person," he said. "A lot of times you say 'very good' even if it's not the right answer because you want to keep them motivated on the task." 
  
 Computer games like Nintendo's Wii can be used to enhance coordination, and as rehab progresses, patients can join basketball and hockey teams or do gardening and other hobbies. They go on field trips to the grocery store or the airport to practice going through security screening and boarding a plane. 
  
 Doctors hope Giffords will do all these things, but Lacey cautions: 
  
 "Very positive early recovery does not guarantee an excellent long-term outcome. It certainly puts her more in that category of people who are likely to do much better, but some patients can plateau and not progress much further." 
  
 Mark Steinhubl wishes he could give Giffords advice. The 20-year-old was shot in the head two years ago in downtown Houston and had rehab at Memorial Hermann. He still can't see out of one eye or hear out of one ear, but he can walk and talk and is a sophomore majoring in chemical engineering at Texas A&M. 
  
 "She needs to realize that it won't be instantaneous like I thought it would be," he said. "I felt like I was accomplishing something every day, meeting a benchmark." 
  
 When he came into the rehab hospital on a stretcher, "I couldn't even sit up," Steinhubl said. When he left a month later, "I didn't walk out, I ran out."

Output:
A slight setback in Gabrielle Giffords’ seemingly miraculous recovery: Fluid buildup in her brain is likely to delay full-fledged rehabilitation, the Houston Chronicle reports. She is expected to remain in intensive care this week, and then doctors will determine whether she can move on to the rehab center, or if she will need a permanent shunt. Even so, Giffords was reportedly more alert and responsive yesterday than she was Friday when she arrived in Houston, and doctors say she responded well to therapy including sitting, standing, and moving while in bed. When she moves on to rehab, it will be with the aim of getting her life back, the AP adds. Rehabilitation used to be seen as a last resort, but has been updated in the past few decades—and the Houston hospital Giffords is at uses state-of-the-art tools. But she faces a hard, and likely sometimes frustrating, road, doctors warn. “Practice, practice, practice” is the only way to get better, says one. The good news? As she improves, some of her rehab could include fun activities like playing Wii, gardening, going on field trips, or joining sports teams.
