HOUSTON (AP) -- Police stood guard as an ambulance took Rep. Gabrielle Giffords from intensive care to a rehabilitation hospital on Wednesday, an encouraging step that came after doctors upgraded her condition from serious to good and removed a tube from her head to drain fluid.
Doctors at Memorial Hermann Texas Medical Center Hospital determined the Arizona congresswoman was healthy enough to move to nearby TIRR Memorial Hermann, where she will continue her rehabilitation work.
Helicopters buzzed overhead and police stopped traffic and blocked the road as an ambulance took Giffords and her husband, astronaut Mark Kelly, a short way to TIRR, which stands for The Institute for Rehabilitation and Research.
Giffords had been in intensive care since her arrival Friday from Tucson, Ariz.
Last week doctors placed a tube in her head to drain excess cerebrospinal fluid. A backup of the fluid can cause pressure and swelling within the brain.
Doctors had said Giffords would remain in the ICU until the tube was removed. In a statement on Wednesday, doctors said they had removed the catheter and that Giffords' recovery had been progressing since her arrival in Houston.
Dr. Gerard Francisco, the head of Giffords' rehabilitation team, said the congresswoman had responded well to therapy in the ICU. However, her move to TIRR will allow her to begin a more intensive program.
"The congresswoman has done very well in her therapy sessions in the ICU," Francisco said in a statement. "It will be good to have her at TIRR Memorial Hermann where we can devote more time to her rehabilitation and recovery."
Giffords was shot in the head Jan. 8 in a rampage that killed six people and injured her and 12 others. The three-term Democratic congresswoman was hit in the forehead while meeting with constituents outside a Tucson supermarket.
