I cannot say for sure, I think its a type of therapy to de-sensetize people to sensory issue. I personally think it would cause me more pain than help me as from what I hear it basically involves being exposed to sensory input that's uncomfortable and painful till you get used to it and learn to deal with it with a smile on your face.

I am however a pessimist though so don't take my word for how it would be. But yeah no way would I subject myself to that If I am right about how it works.
