Just to add to that article (and also the name of the therapy), EMDR is not limited to eye movements. It started out as a patient's eyes following the therapist's finger moving back and forth. It was found that other types of movements can stimulate bilateral processing in the brain... this can include eye movements to follow the therapist's finger, following a light that moves back and forth, holding small instruments in the hands that alternately buzz, and also tapping on the shoudlers or knees with arms crossed-- the therapist OR the patient can do the tapping. The selection of the physical movement usually depends on comfort, connection, and level of trust. I started out using the buzz things or even the light with my T-- but because of my need for a strong face to face connection, we stopped using those. Sometimes I follow his finger with my eye movements, and sometimes he does continuous, alternative tapping on my knees while I am experiencing the memory.
