Abstract:
Elevated psychophysiological parameters and heightened physiological reactivity to trauma-related cues
are acquired changes following trauma exposure. Measuring improvement in these variables is an appropriate
evaluation of outcome in treatment studies. Heart Rate Variability (HRV) is a computerized measure
of physiological responsivity derived from Holter ECG recording. Four female outpatients with persistent
post-traumatic symptoms and personal impairment following “small t” trauma exposure underwent a
course of EMDR treatment and were assessed at baseline, end of treatment, day 30 and day 90 of followup,
using self-report symptom scales and 90-min Holter ECG recordings. Symptom scores decreased
between baseline and end of treatment, with improvement maintained at follow-up. Several HRV measures
changed favorably in different recording intervals. HRV is a feasible and sensitive method to measure
physiological changes in the treatment of individuals distressed by “small t” trauma. Further investigation
is advisable to expand these preliminary data.

Abstract:
This study aims to measure psychophysiological
parameters during activation of internal resources k g .
positive memories) and to compare these to activated traumatic
internal networks.
Antecedent studies show that traumatic stimulation on patients
with posttraumatic stress disorder (PTSD) finalizes in various
psychophysiological correlates. During therapy of these patients
a strong demand for activation of internal resources, i.e. activation
of fortitude and positives thoughts, exists. Especially EMDR
therapy uses resource stimulating elements such as position of
power and absorption in preparation for exposure. In this study
standardized EMDR protocols establish a solid basis to explore
individual internal resources.
Researches on trauma stimuli in EMDR- patients show effects
on parasympathetic tonus (Sack 2006) as well as increased cerebral
blood flow in defined brain regions (Levin 1999. Lamprecht
2000). Especially the heart rate variability (HRV) may describe
the sympatheticovagal balance (Cohen, 2002, Porges 1991). This
study focuses on psychophysiological effects and neurobiological
regulative mechanisms of stabilizing methods and activation of
internal resources in PTSD patients and healthy control group.
Methods: Healthy subjects and patients with diagnosed PTSD
(DIAX) listened to a commonly neutral script, an individual
trauma script and an individual absorption script. Following
each script measurements of heart rate variability (HRV), respiratory
flow, skin conductance responses (SCR) and skin blood
flow (LCF, TU50%) took place.
Results: Preliminary results revealed a significant reduced heart
rate variability in patients compared to the healthy controls in
reaction to the stress script as well as to the positive and the
neutral scripts.
Conclusion: To our knowledge this is the first time to be proven
that altered autonomous functions are found in PTSD not only
in reaction to traumatic reminders, but even to a positive, resource
activation situation. This provides our basement for further
research. Detailed analysis of different effects to each script
on both groups are currently underway.
