I work extensively with EMDR. It has a particular protocol that when followed is quite helpful for many. EMDRIA.org is a link for the site that supports the trainings and explanations about this approach. Take a look at the explanation for clients section. It an evidenced based protocol that is highly effective for trauma and negative beliefs or cognitions that can result from traumatic situations or have been internalized. When these negative cognitions interfere with life EMDR can be used to help clear this and raise better cognitions or beliefs. It does not involve replaying the story. It can also be used for phobias, blocks and even athletic enhancement. f
Francine Shapiro is the mother of this approach. I value it highly.
