Castro kidnap victim Michelle Knight on Dr Phil show
A woman who was held in brutal captivity in an Ohio house for 11 years has said she was hung "like a fish" from her feet and neck.
Michelle Knight is the first of three women who escaped Ariel Castro's abuse to tell her story at length.
In advance clips from an interview on the Dr Phil show, Ms Knight describes her torturous imprisonment.
Castro, who was imprisoned for life for the crimes, died in an apparent suicide in an Ohio jail in September.
Ms Knight, Gina DeJesus and Amanda Berry were freed from his Cleveland house after Ms Berry managed to escape in May and call for help.
He abducted the women from the streets of his Cleveland neighbourhood and held them for about a decade before they were freed.
Ms Knight was 21 when she was kidnapped in August 2002.
Officials have said he kept the women chained for long periods in the house, beating, starving and sexually assaulting them.
Castro pleaded guilty in July to the 937 charges against him, including multiple counts of kidnapping, rape and aggravated murder, in connection with the beating of a pregnant captive until she miscarried.
In a video published ahead of the two-part interview to be broadcast this week, Ms Knight told host Phil McGraw she was "tied up like fish, an ornament on the wall, that's the only way I can describe it".
'Her own voice'
She said she was bound and hung by the neck, arms and feet.
Mr McGraw told the Cleveland Plain Dealer after hearing her story, "you wonder how anyone lasted a day let alone more than a decade".
"In the 12 years of doing the Dr Phil show, no one has changed me like Michelle Knight and her story of survival," he said.
Mr McGraw also said Ms Knight was "eager" to have her own voice after the years of abuse by Castro.
The interview will run over two days on Tuesday and Wednesday.
Mr McGraw said that out of respect for the two other women, Ms Knight would only discuss her own experience.
At Castro's sentencing hearing in August, Ms Knight, the only victim to appear in court, said: "You took 11 years of my life away, but I've got my life back. I spent 11 years in hell. Now your hell is just beginning."
