EMDR works with the neuro-networks in the brain in a way that helps to release past trauma and beliefs and bring you more into present time. This is done through what is called bilateral stimulation, which is a stimulation of the right and left hemispheres of the brain. I usually do this by using equipment that produces sound tones in each ear and buzzers in each hand. The bilateral stimulation used in EMDR seems to unlock the nervous system and allow the brain to process the experience that has been stuck. The ability to process trauma is naturally built into the nervous system. EMDR helps to get the mind out of the way and allow that to happen.
I have over 20 years experience with EMDR. I have found it to be helpful with any and all issues that people bring. I often combine EMDR with Somatic Experiencing, which I find to be highly effective. I also utilize EMDR to facilitate clients being present in the body with their direct experience in the moment.
