The following information was taken directly from EMDRIA.com which is an organization that provides EMDR training and continuing education to therapists.
How was EMDR developed?
In 1987, psychologist Dr. Francine Shapiro made the chance observation that eye movements can reduce the intensity of disturbing thoughts, under certain conditions.
Dr. Shapiro studied this effect scientifically and, in 1989, she reported success using EMDR to treat victims of trauma in the Journal of Traumatic Stress.
Since then, EMDR has developed and evolved through the contributions of therapists and researchers all over the world. Today, EMDR is a set of standardized protocols that incorporates elements from many different treatment approaches.
How does EMDR work?
No one knows how any form of psychotherapy works neurobiologically or in the brain. However, we do know that when a person is very upset, their brain cannot process information as it does ordinarily. One moment becomes "frozen in time," and remembering a trauma may feel as bad as going through it the first time because the images, sounds, smells, and feelings haven’t changed. Such memories have a lasting negative effect that interferes with the way a person sees the world and the way they relate to other people.
EMDR seems to have a direct effect on the way that the brain processes information. Normal information processing is resumed, so following a successful EMDR session, a person no longer relives the images, sounds, and feelings when the event is brought to mind. You still remember what happened, but it is less upsetting. Many types of therapy have similar goals. However, EMDR appears to be similar to what occurs naturally during dreaming or REM (rapid eye movement) sleep. Therefore, EMDR can be thought of as a physiologically based therapy that helps a person see disturbing material in a new and less distressing way.
How long does EMDR take?
One or more sessions are required for the therapist to understand the nature of the problem and to decide whether EMDR is an appropriate treatment. The therapist will also discuss EMDR more fully and provide an opportunity to answer questions about the method. Once therapist and client have agreed that EMDR is appropriate for a specific problem, the actual EMDR therapy may begin.
A typical EMDR session lasts from 60 to 90 minutes. The type of problem, life circumstances, and the amount of previous trauma will determine how many treatment sessions are necessary. EMDR may be used within a standard "talking" therapy, as an adjunctive therapy with a separate therapist, or as a treatment all by itself.
Does EMDR really work?
Approximately 20 controlled studies have investigated the effects of EMDR. These studies have consistently found that EMDR effectively decreases/eliminates the symptoms of post traumatic stress for the majority of clients. Clients often report improvement in other associated symptoms such as anxiety. The current treatment guidelines of the American Psychiatric Association and the International Society for Traumatic Stress Studies designate EMDR as an effective treatment for post traumatic stress. EMDR was also found effective by the U.S. Department of Veterans Affairs and Department of Defense, the United Kingdom Department of Health, the Israeli National Council for Mental Health, and many other international health and governmental agencies. Research has also shown that EMDR can be an efficient and rapid treatment.
What kind of problems can EMDR treat?
Scientific research has established EMDR as effective for post traumatic stress. However, clinicians also have reported success using EMDR in treatment of the following conditions:
Sexual and/or Physical abuse
Body dysmorphic disorders
