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.
The amount of time the complete treatment will take depends upon the history of the client. Complete treatment of the targets involves a three pronged protocol (1-past memories, 2-present disturbance, 3-future actions), and are needed to alleviate the symptoms and address the complete clinical picture. The goal of EMDR therapy is to process completely the experiences that are causing problems, and to include new ones that are needed for full health. "Processing" does not mean talking about it. "Processing" means setting up a learning state that will allow experiences that are causing problems to be "digested" and stored appropriately in your brain. That means that what is useful to you from an experience will be learned, and stored with appropriate emotions in your brain, and be able to guide you in positive ways in the future. The inappropriate emotions, beliefs, and body sensations will be discarded. Negative emotions, feelings and behaviors are generally caused by unresolved earlier experiences that are pushing you in the wrong directions. The goal of EMDR therapy is to leave you with the emotions, understanding, and perspectives that will lead to healthy and useful behaviors and interactions.
Finding ways to guide yourself into the relaxation response and address the long-term effects of trauma are key elements in treating fibromyalgia. What may work for one person, may not for another. That is why it is important to survey many alternate treatments to gain a better quality of life.
