Client's interested in EMDR as treatment for trauma will generally meet for 90 minute sessions weekly during the most active work. EMDR includes an eight-phase treatment. Eye movements (or other bilateral stimulations) are used. The client and therapist will select a memory to target in which the client will hold different aspects of the event or thought in his/her mind. It is believed that the bilateral stimulation connects the biological mechanisms that are involved in Rapid Eye Movement (REM) sleep. This accesses internal memory associations and the client starts to process the disturbing feelings and related (associated) memories. The purpose is to transform the meaning of painful events at the emotional level, therefore, when the memory is recalled, after successful treatment, there is no longer distress and pain felt. For example, a client that was raped may shift from feeling horror, helplessness, and self-disgust to holding a firm belief that, "I survived it, I am strong, and it was not my fault." The goal is to help the client feel more empowered by experiences that once debased them. EMDR works in the past, present, and future.
