[TPM SLIDESHOW: Rep. Gabrielle Giffords: On The Job In Arizona]
The doctors are now doing physical therapy with Giffords, including dangling her legs over the side of the bed, which Lemole said helps gauge the strength in her legs.
"I will say that she is able to move both of those legs to command," Lemole said. "That's huge."
Lemole acknowledged the "intangibles" that aid in the recovery process, referring to the company of friends and family.
"Miracles happen every day," he said. "A lot of medicine is outside of our control, and we're wise to acknowledge miracles."
Dr. Peter Rhee said one patient still remains in critical condition, and four remain in fair condition.
