I will fully admit that I don't know a lot about EMDR (Eye Movement Desensitization and Reprocessing), but I have seen people talk about it positively and say that it has helped them a lot.
EMDR therapy involves attention to three time periods: the past, present, and future. Focus is given to past disturbing memories and related events. Also, it is given to current situations that cause distress, and to developing the skills and attitudes needed for positive future actions.
After the clinician has determined which memory to target first, he asks the client to hold different aspects of that event or thought in mind and to use his eyes to track the therapist’s hand as it moves back and forth across the client’s field of vision. As this happens, for reasons believed by a Harvard researcher to be connected with the biological mechanisms involved in Rapid Eye Movement (REM) sleep, internal associations arise and the clients begin to process the memory and disturbing feelings. In successful EMDR therapy, the meaning of painful events is transformed on an emotional level. For instance, a rape victim shifts from feeling horror and self-disgust to holding the firm belief that, “I survived it and I am strong.”
