Psychophysiological monitoring during EMDR Evidence for stimulation associated changes in autonomic tone
We report about an empirical investigation of EMDR working mechanisms. 55 EMDR sessions were psycho physiologically monitored including start and end of each stimulation set (N = 811). The results demonstrate a sharp increase of parasympathetic tone (RMSSD) and a prolonged decrease of heart rate as soon as stimulation begins. Observations during treatment sessions show a significant psychophysiological dearousal in terms of a decrease of HR and a significant increase of parasympathetic tone. Both the deconditioning hypothesis (dearousal during session) as well as the accelerated information processing hypothesis (enhancement of parasympathetic tone during stimulation) are supported by our empirical results.
