Jane,

You have to be careful about that site because some of that information is really outdated. What it says was true about 5 years ago, but now there is prove from independent studies.
Traditional desensitization threapy takes a lot of time and the client must think about the traumatic events over and over again for hours. EMDR works much quicker than that, and the time you think about the traumatic memories is much less. Most T's who are trained in EMDR can would tell you that it is much quicker relief than the traditional methods they used a long time ago.

I belive that the eye movements or any bilateral stimulation isn't doing all the work, EMDR is a combination of the eye movements and cogitinive therapy together.

Now I don't beleive that what was said about EMDR works by forcing the 2 sides of the brain to work together, is rather simplistic. and not really how it works. But claiming there is no scientific proff by looking at that web site that contains outdated info, isn't proff either that it doesn't work.
