One of the most effective treatments for anxiety, stress and trauma is Eye Movement Desensitization Reprocessing (EMDR), founded by Dr. Francine Shapiro. Research shows that many times talking about a trauma can be retraumatizing to a person (van der Kolk, 1996). EMDR is specifically designed to circumvent discussing traumatic memories by having the memory get processed in the brain, moving it from the right hemisphere where there is much reactivity and emotion and no separation of time, into the left hemisphere, where the emotional reaction is no longer and logic and reason are able to be accessed for integrating the experience.
EMDR can be used through a variety of of kinesthetic interventions, such as an alternation of tapping on shoulders, knees, moving one's finger to have a person's eyes follow, and so forth, which all involve bi-lateral brain stimulation. fMRIs show that through these techniques, traumas become "metabolized" or processed in a way that is much quicker than just by using talk-therapy. EMDR is not recommended for all types of trauma, such as complex trauma, and a thorough evaluation needs to occur before beginning treatment.
