Eye Movement Therapy is a therapy where the patient, guided by the therapist, performs movements with the eyes in order to treat psychological trauma and the resulting blockages. Eye Movement Therapy helps to alleviate the emotional burden linked to traumatic events. 

This therapy is specifically aimed at people with a notable behavioral change, conscious or unconscious, following a trauma (accident, sexual assault, terrorist attack, moral or physical harrassment, rape, etc.). 
These people regularly relive the traumatic event in the form of flashes or dreams and can have strong and uncontrolled reactions which will considerably modify their attitudes in their daily life. 

Eye movement activates all parts of the brain and provides the patient with new emotional and cognitive resources.
The alternating movement of the eyes restarts the processing of information, allowing the individual to move beyond the traumatic phase, to modify their perception and to draw new resources from their present reality. 
In fact, Eye Movement Therapy helps unblock negative emotions stored in the nervous system, then helps the brain reprocess the experience so that it is assimilated.
