Michelle Knight, one three Cleveland women who survived a decade of imprisonment and torture by Ariel Castro, told Phil McGraw she was often "tied up like a fish" while being repeatedly sexually and physically abused.
In a clip released Tuesday, Dr. Phil asked Knight what Castro used to tie her up once he had abducted her.
"One of those orange extension cords," Knight said. "I was tied up like a fish, an ornament on the wall. That's the only way I can describe it. I was hanging like this," she said. "I was tied by my neck and my arms with the extension cord."
Knight motioned to her hands to indicate that she was hanging sideways on the wall with her feet and head at the same heights.
Dr. Phil told CNN's Anderson Cooper on Monday that he was impressed by Knight's determination to survive Castro's abuse.
"It's astounding to me that she had the strength that she did," he told "Anderson Cooper 360". "Now think about this. He chained her to this pole around her neck, put a motorcycle helmet (on her head), strapped it tight, closed the visor and leaves her there for days and days at the time."
When she was not hanging from the wall, she was taken down to what Dr. Phil described as a "just nasty" basement where Castro chained her to a pole and placed a motorcycle helmet on her head while he repeatedly sexually assaulted her.
"She did hold on to hope," Dr. Phil said. "She had one beacon ahead of her, and that was her 2-and-a-half-year-old son. She said, 'I have to live for him. And I'm fighting to stay alive for him.'"
Knight was 21 when she disappeared in 2002. Knight said Castro initially thought she was a prostitute. Knight was rescued in May along with two other young women, Amanda Berry and Gina DeJesus.
Castro pleaded guilty to 937 counts of rape, kidnapping, torture and aggravated murder and was sentenced to life in prison without parole plus 1,000 years by an Ohio Judge on Aug 1. He was found dead in his jail cell on Sept. 3.
Knight will be the first of the three women to publicly tell her story with a two-part appearance on the "Dr. Phil Show", which will air on Tuesday and Wednesday.
