EMDR - Eye Movement Desensitization and Reprocessing - is a
psychological method for treating experientially based disorders and
emotional difficulties that are caused by disturbing life experiences,
ranging from traumatic events such as combat stress, assaults, and
natural disaster, to upsetting childhood 
events.
EMDR is a complex method that brings together elements from well-established clinical theoretical orientations including psychodynamic, cognitive, behavioral, and client-centered (Shapiro, 2001).
In 1987, psychologist Francine Shapiro made the initial observation that led to the development of EMDR. She discovered that her voluntary eye movements reduced the intensity of negative, disturbing thoughts.
Since that time, EMDR has become one of the most researched psychotherapeutic treatments for posttraumatic stress disorder (PTSD). Empirical evidence suggests that EMDR is one of the most efficient treatments for PTSD. Studies indicate that EMDR may also be effective in treating various mental disorders, including specific phobias, performance anxiety, panic disorder, body dysmorphic disorder, complicated mourning, and chronic pain.
The American Psychiatric Association Practice Guideline for the Treatment of Patients with Acute Stress Disorder and Posttraumatic Stress Disorder has given EMDR the same status as Cognitive Behavior Therapy as an effective treatment for ameliorating symptoms of both acute and chronic PTSD.
