After a doctor X-rayed one prisoner's badly broken feet, his colleague gave interrogators the go-ahead to force him to stand for 52 hours.
They were employed in an $81-million dollar CIA interrogation program which ran for at least seven years under the Bush administration beginning in 2002.
Public documents suggest it was led by two military psychologists, John Bruce Jessen and James Mitchell, whose techniques are widely seen as torture.
A lawsuit filed in 2017 by the American Civil Liberties Union on behalf of former prisoners shines new light on the grisly details of the tactics the doctors approved for use on terrorism suspects in an attempt to extract information from them after the events of September 11, 2001. These tactics, which range from water-boarding to "walling" — a method that involves pushing a person into a flexible plywood wall so hard that it creates a disturbing sound that pierces the ear — are widely considered torture by experts.
