In Active Release Therapy, as pressure is applied, movement is also employed. For example, pressure might be applied to a location on the shoulder while the arm is moved.

There may well be no books for the general public. zI don’t know. There is training for those wishing to be certified in it.
As for Wikipedia having their article on it nominated for deletion: For example, if I wrote an entry on anabolic steroids for Wikipedia, it would be attacked for needing references. However if someone else wrote the article and cited me as the reference, then it would be fine. Perhaps the fly that someone has in their soup is that there may be no book referenced and therefore statements are opinion and unsubstantiated.
