Francine Shapiro PhD. created the EMDR Institute as a way to train clinicians in an effective way to trauma after discovering this process. On the site are links to pages that explain EMDR in detail.
The EMDR International Association (EMDRIA) is the professional association for clinicians who are trained in and use this therapy.
Eye Movement Desensitization and Reprocessing (EMDR) therapy is an extensively researched, effective psychotherapy method proven to help people recover from trauma and other distressing life experiences, including PTSD, anxiety, depression, and panic disorders.
The American Psychiatric Association, the International Society for Traumatic Stress Studies, the Substance Abuse and Mental Health Services Administration, the U.S. Dept. of Veterans Affairs/Dept. of Defense, The Cochrane Database of Systematic Reviews, and the World Health Organization among many other national and international organizations recognize EMDR therapy as an effective treatment.
