"Manning will receive a credit of 1,293 days for the time he has been confined prior to the sentence, including 112 days of credit for abusive treatment he was subjected to in the brig at the Quantico Marine Base."[1]
The math isn't clear, but it seems to confirm he was somehow compensated for the horrible treatment. I would call it psychological abuse, not sure if it equates to torture. Given that it's a sort of admission of wrongdoing, I suspect the days of credit were part of the plea deal--otherwise he'd be persuing further actions over it.

Consider that more people kill themselves because they can't bear psychological pain than they do because they can't bear physical pain.
