Face down restraint is being used against adult mental health patients in Wales, despite government advice to the contrary.
Figures given exclusively to In Focus show that the controversial method of controlling patients has been used more than 800 times across Wales since April 2012.
In 2005, however, the Welsh Government published guidance in which it said: "under no circumstances should any individual be ever be restrained in a face down position."
It's prompted mental health campaigners to call for an outright ban on the practise, which has been described as life threatening.
'Helen' has first hand experience of what it is like to be restrained, face down.
She was diagnosed with bipolar disorder in the early 90s and it was during a manic episode that she was restrained.
I wasn't in there because I had committed a crime and I needed to be held down. I was ill. People have got to understand it's an illness. It was almost abusive. Well, it was abusive. I didn't sign up for that when I went to get help for my illness. You've got to fight for your life. I didn't know what they were doing I hadn't experienced it before. I hate to think anyone else could be going through that now. It's inhumane.
