Abstract:
EMDR combines stimuli that evoke divided attention – e.g. eye movements – with exposure to traumatic memories. Our objective was to investigate psycho-physiological correlates of EMDR during treatment sessions. A total of 55 treatment sessions from 10 patients with PTSD was monitored applying impedance cardiography. Onset of every stimulation/exposure period (n = 811) was marked and effects within and across stimulation sets on heart rate (HR), heart rate variability (HRV), pre-ejection period (PEP) and respiration rate were examined. At stimulation onsets a sharp increase of HRV and a significant decrease of HR was noticed indicating de-arousal. During ongoing stimulation, PEP and HRV decreased significantly while respiration rate significantly increased, indicating stress-related arousal. However, across entire sessions a significant decrease of psycho-physiological activity was noticed, evidenced by progressively decreasing HR and increasing HRV. These findings suggest that EMDR is associated with patterns of autonomic activity associated with substantial psycho-physiological de-arousal over time. [Author Abstract]

Abstract:
This study investigates changes of stress-related psychophysiological reactions after treatment with EMDR. 16 patients with PTSD following type I trauma underwent psychometric and psychophysiological assessment during exposure to script-driven imagery before and after EMDR and at 6-month follow-up. Psychophysiological assessment included heart rate (HR) and heart rate variability (HRV) during a neutral task and during trauma script listening. PTSD symptoms as assessed by questionnaire decreased significantly after treatment and during follow-up in comparison to pretreatment. After EMDR, stress-related HR reactions during trauma script were significantly reduced, while HRV indicating parasympathetic tone increased both during neutral script and during trauma script. These results were maintained during the follow-up assessment. Successful EMDR treatment may be associated with reduced psychophysiological stress reactions and heightened parasympathetic tone.

Language: English

Abstract:
“Where I am? I am somewhere between heaven and earth, but I don't know where exactly." "My therapist waited for my anger, but it just isn't there...nowhere” – “I can't imagine anything helpful when I feel bad, I just don't have the energy... it's all too much for me." – “I just want to give up...” Reaction to traumatic events can vary a lot. This is true even when a PTSD has been diagnosed. Contrary to the 'classical' hyper-arousal response to traumatic memories there is also a different pattern of response that is characterized by a lack of an increase in heart rate, and very different pattern of neural activations, despite having a severe case of acute and subsequent PTSD'[l] and may go along with (peri- and posttraumatic) dissociation, emotional numbness, exhaustion, withdrawal and depression. The above statements belong to people with this pattern of response who have experienced subsequent difficulties already in the stabilization phase of their trauma-therapy. First, I will present an understanding of this symptomatology, the hypothesis being a predominance of the dorsal vagal system (see: Polyvagal Theory [2] and activation of the early withdrawal reflex (or: fear-paralysis reflex). This goes along with particular cognitive and especially emotional and physical features. Second, I will present a way to work with this condition, taking into account that the completion of "interrupted action." In this case does not imply an outward (fight or fight response) but an inward orientation withdrawal). EMDR with an adjusted protocol and tactile bilateral stimulation provides the way to process and pull through this interrupted (or unsatisfied) organismic withdrawal and the fear mostly associated with this process. Returning from this deep and primary withdrawal from life brings back the energy and the patient turns back towards life; vagal predominance subsides and the stuck impulse to withdraw releases. 1.

Abstract:
The basic theoretical postulations on PTSD are given in the first part of the work. Hypotheses are given on PTSD as being a kind of conditioned emotional reaction to trauma and, possibly, an illness that has disturbed REM sleep mechanism at its roots. The second part describes behavioural and cognitive techniques that have been proven empirically to be successful in the treatment and the prevention of this disorder. [Author Abstract]

Abstract:
The present study was designed to isolate the effects of the eye-movement component of the Eye Movement Desensitization and Reprocessing (EMDR) procedure in the treatment of fear of public speaking. Seventy-one undergraduate psychology students who responded in a fearful manner on the Fear Survey Schedule II and on a standardized, self-report measure of public speaking anxiety (Personal Report of Confidence as a Speaker; PRCS) were randomly assigned to one of four groups in a 2 × 2 factorial design. The two independent variables assessed were treatment condition (imagery plus eye movements vs. imagery alone) and type of imagery (fear-relevant vs. relaxing). Dependent variables assessed were self-reported and physiological anxiety during exposure and behavioral indices of anxiety while giving a speech. Although process measures indicated exposure to fear-relevant imagery increased anxiety during the procedure, no significant differences among groups were found on any of the outcome measures, except that participants who received eye movements were less likely to give a speech posttreatment than participants who did not receive eye movements. Addition of the eye movements to the experimental procedure did not result in enhancement of fear reduction. It was concluded, consistent with the results of past research, that previously reported positive effects of the EMDR procedure may be largely due to exposure to conditioned stimuli (ScienceDirect).

Language: English

Format: Conference

Abstract:
Despite the emergence of many theories on biological EMDR mechanisms, research is still needed to understand the healing processes of EMDR. We conducted four experiments to explore the effects of EMDR on PTSD with 17 to 22 patients suffering from one unique trauma. The first experiment evidenced attentional bias in PTSD towards negative words that disappeared after successful EMDR Therapy. The second experiment has shown a less efficient control of emotion in PTSD as compared to healthy controls. This altered emotional suppressing measured through psychophysiological responses was restored after symptoms disappearance following EMDR. The third experiment also using psychophysiological measures confirmed the increased fear sensitization and delayed fear extinction in PTSD and again the restoration of a normal fear conditioning and extinction processes after EMDR. The last experiment explored the negative emotional cerebral mechanisms using functional magnetic resonance imagery in PTSD. Activities in prefrontal structures were modified in PTSD as compared to healthy controls. After the EMDR treatment accompanied by symptoms removal, the prefrontal responses were not different between PTSD patients and their controls. Theoretical issues of these results will be discussed in order to integrate cognitive, psychophysiological and cerebral mechanisms observations.

A pesar del emerger de muchas teorías sobre los mecanismos biológicos del EMDR, la investigación aún necesita entender el proceso de curación que se produce en EMDR. Hemos realizado 4 experimentos para explorar los efectos del EMDR en TEPT de 17 a 22 pacientes que sufrieron un único trauma. El primer experimento evidencia un sesgo atencional del TEPT ante las palabras negativas que desaparecen después de una terapia exitosa de EMDR. El Segundo experimento mostró una baja eficiencia del control de las emociones en los TEPT comparados con el control de individuos sanos. Esta alterada supresión emocional medida a través de respuestas psicofisiológicas fue restaurada después de una desaparición de los síntomas realizando EMDR. El tercer experimento también confirma mediante medidas psicofisiológicas el aumento de la sensación de miedo y un retraso en la extinción del mismo en el TEPT. De nuevo tras administrar una terapia EMDR se produjo una restauración a una condición normal de miedo y un proceso de extinción. El último experimento explica los mecanismos negativos emocionales cerebrales usando resonancia funcional magnética en TEPT. La actividad en las estructuras prefrontales fue modificada en el TEPT comparado con el control. Después del tratamiento de EMDR acompañado de una remisión de los síntomas, las respuestas prefrontales no fueron diferentes entre los pacientes con TEPT y los controles. Cuestiones teoréticas sobre estos resultados serán discutidas con el fin de integrar cognitivamente, psicofisiológicamente y observar los mecanismos cerebrales del EMDR.

Language: English

Format: Journal

Abstract:
This study aimed to investigate the psychophysiological correlates and the effectiveness of different dual-attention tasks used during eye movement desensitization and reprocessing (EMDR). Sixty-two non-clinical participants with negative autobiographical memories received a single session of EMDR without eye movements, or EMDR that included eye movements of either varied or fixed rate of speed. Subjective units of distress and vividness of the memory were recorded at pre-treatment, post-treatment, and 1 week follow-up. EMDR-with eye movements led to greater reduction in distress than EMDR-without eye movements. Heart rate decreased significantly when eye movements began; skin conductance decreased during eye movement sets; heart rate variability and respiration rate increased significantly as eye movements continued; and orienting responses were more frequent in the eye movement than no-eye movement condition at the start of exposure. Findings indicate that the eye movement component in EMDR is beneficial, and is coupled with distinct psychophysiological changes that may aid in processing negative memories.

Abstract:
EMDR is presented by its founder [Shapiro] as a method for allowing long delayed learning to take place through as yet unknown neural mechanisms which are triggered by the repetitive eye movements of the procedure. In Stekete and Goldstein's appraisal of research examining EMDR's effectiveness we begin to see the contours of an empirical response to some of the earlier miraculous and enigmatic clinical case reports using this procedure.

Language: English

Format: Journal

Abstract:
Numerous studies have provided evidence for the efficacy of eye movement desensitization and reprocessing therapy (EMDR) in the treatment of PTSD, including recent studies showing it to be more efficient than therapist-directed flooding. But few theoretical explanations of how EMDR might work have been offered. Shapiro, in her original description of EMDR, proposed that its directed eye movements mimic the saccades of rapid eye movement sleep (REM), but provided no clear explanation of how such mimicry might lead to clinical improvment. We now revisit her original proposal and present a complete model for how EMDR could lead to specific improvement in PTSD and related conditions. We propose that the repetitive redirecting of attention in EMDR induces a neurobiological state, similar to that of REM sleep, which is optimally configured to support the cortical integration of traumatic memories into general semantic networks. We suggest that this integration can then lead to a reduction in the strength of hippocampally mediated episodic memories of the traumatic event as well as the memories' associated, amygdala-dependent, negative affect. Experimental data in support of this model are reviewed and possible tests of the model are suggested. [Author Abstract]

Abstract:
10 patients suffering from PTSD following a severe traumatic event, were assessed with event-related brain potentials (ERPs) in a modified oddball paradigm containing auditory standard, target, and novel tones. ERPs were assessed before and after a treatment session using the eye movement desensitization and reprocessing method. Compared to a control group that underwent sham treatment, ERPs of the patients showed a reduction of the P3a component in the post-treatment recording, suggesting a reduced orienting to novel stimuli and reduced arousal level after the treatment. Moreover, psychometric assessment revealed a marked improvement of the PTSD symptoms after treatment. [Author Abstract]

Language: English

Format: Journal

Abstract:
Patients with PTSD demonstrate abnormal psychophysiological responses to stressful events. Given that eye movement desensitization and reprocessing (EMDR) therapy appears to be a treatment of choice for trauma victims, the aim of the present study was to determine if psychophysiological responses to stress decreased after a single EMDR session. 6 PTSD patients were treated by an EMDR therapist. Their psychophysiological responses (heart rate and skin conductance) were recorded before and after the EMDR session under two conditions: (a) in a relaxed state and (b) while visualizing their own traumatic event. At the end of the session, all patients had a significant reduction in their PTSD symptoms, which confirms previous results demonstrating the efficacy of the EMDR approach. Second, after only one EMDR session, heart rate and skin conductance during the trauma recall decreased significantly as compared to a relaxing state. [Author Abstract]

Abstract:
Eye movement desensitization (EMD) was investigated in an experimental multiple baseline across subjects design. Six subjects who met the diagnostic criteria for PTSD were included in the study. While the EMD technique advanced by Shapiro has been reported to be clinically effective, major methodological issues have been raised which remain to be addressed. One issue raised is whether exposure to the traumatic image is sufficient to account for the reported clinical effects of EMD or whether the addition of saccadic eye movements is central to the treatment. This study attempted to address this concern by comparing two EMD-based procedures: a Non-saccade phase (without the saccadic eye movements) which functioned as a control and a second that included saccadic eye movements. Dependent variables included self-report information (SUDs, behavioral symptoms reports) and physiological data (heart rate and systolic blood pressure). The results showed no significant decreases in SUDs level with the EMD minus the saccadic eye movements procedure. However, five of the six subjects reported clinically significant decreases in their SUDs levels with the inclusion of the saccadic eye movements. This study appears to corroborate previous work employing single-case design as well as pre and postcomparisons. [Author Summary]

Abstract:
4 Vietnam veterans diagnosed with PTSD were treated with 12 sessions of eye movement desensitization and reprocessing (EMDR), targeting their combat memories. An extensive multimodal assessment battery showed very substantial clinical improvement for 3 of the veterans along a number of psychological dimensions that characterize the disorder, but not along several physiological parameters. A fourth veteran showed only very modest changes. The results are discussed in terms of the importance of several issues, including numbers of treatment sessions and differential effects of treatment on cognitive-behavioral and physiological symptoms.

Format: Dissertation/Thesis

Abstract:
This study explored the effects of eye movements, as compared with eye stabilization and an attention control in reducing anxiety related to public speaking in a non-clinical sample. Nineteen subjects with public speaking anxiety identified their worst memory of speaking in public and either moved their eyes in cadence with the experimenter's fingers, fixated their eyes on the experimenter's fingers, or simply talked about negative experiences related to public speaking. Reduction in anxiety was measured by the Subjective Units of Disturbance scale (Wolpe, 1982) or the Personal Report of Confidence as a Speaker (Paul, 1966). Cognitive change was measured by the Validity of Cognition scale (Shapiro, 1989). Global symptoms were measured by the Symptom Checklist-90-Revised (SCL-90-R, Derogatis, 1983). Analysis of the data indicated that there was no significant difference between groups on any of the measures. This study did not explore the efficacy of Eye Movement Desensitization and Reprocessing (EMDR), but rather the effects of eye movements alone. According to the results of the this study, eye movements are not sufficient to create the kind of changes seen in the EMDR literature.

Abstract:
The purpose of this study is to evaluate the short-term effectiveness of eye movement desensitization (EMD) in reducing negative affect associated with traumatic memory in PTSD patients. In addition to evaluating the general efficacy of the EMD technique, we were also interested in controlling for the possible contribution of an exposure effect in accounting for any positive outcome. Shapiro finds that the technique can be effective in only one session. The present study uses two sessions of EMD offered to veterans diagnosed with combat-related PTSD. [Adapted from Text, p. 30]

Abstract:
Comments on the book by Francine Shapiro (see record 2001-05049-000). I was fortunate to observe Shapiro’s concern for the principles of science in the development of eye movement desensitization and reprocessing (EMDR). She insisted that EMDR be called experimental until after there was supportive peer-reviewed literature, limited training to mental health professionals, and strongly encouraged research. EMDRIA and its peer-reviewed journal have generally continued in this admirable direction. However, when an association is organized around a specific method of treatment rather than a problem area or a more general philosophy of approach, the question of orthodoxy must be addressed. At its best, orthodoxy ensures that practice is consistent with what has been demonstrated to be worthwhile, and all benefit from adherence. Also, there are aspects of the adaptive information processing (AIP), as it is described in the text, that are debatable and some that appear even self-contradictory. One example is Shapiro’s claim that the AIP is a “psychophysiological” model while also denying that enough is known about the details of psychophysiology to offer an explicit model.

Abstract:
Eye movement desensitization and reprocessing (EMDR) is an established treatment for post-traumatic stress disorder (PTSD). However, its working mechanism remains unclear. This study explored physiological correlates of eye movements during EMDR in relation to current hypotheses; distraction, conditioning, orienting response activation, and REM-like mechanisms. During EMDR therapy, fingertip temperature, heart rate, skin conductance, expiratory carbon dioxide level, and blood pulse oximeter oxygen saturation, were measured in male subjects with PTSD. The ratio between the low and high frequency components of the heart rate power spectrum (LF/HF) were computed as measures of autonomic balance. Respiratory rate was calculated from the carbon dioxide trace. Stimulation shifted the autonomic balance as indicated by decreases in heart rate, skin conductance and LF/HF-ratio, and an increased finger temperature. The breathing frequency and end-tidal carbon dioxide increased; oxygen saturation decreased during eye movements. In conclusion, eye movements during EMDR activate cholinergic and inhibit sympathetic systems. The reactivity has similarities with the pattern during REM-sleep. [Author Abstract]

Abstract:
Recent years have seen significant advances in understanding psychosocial stress and its clinical management. Now in a thoroughly revised and expanded third edition, this comprehensive work reviews effective stress management techniques and their applications for treating psychological problems and enhancing physical health and performance. Bringing together recognized leaders in the field to present their respective approaches and demonstrate the nuts and bolts of intervention, the volume is structured for optimal use as a clinical reference and text. All chapters retained from the prior edition have been extensively rewritten, and many new chapters have been added. Part I examines conceptual foundations and describes basic mechanisms of stress and relaxation. Part II, the largest section, covers the full range of methods, including progressive relaxation, hypnosis, biofeedback, meditation, cognitive methods, and other therapies. Each tightly edited chapter: (1) Details the method's history, theoretical underpinnings, and evidence base; (2) Spells out assessment procedures and techniques; (3) Provides step-by-step implementation guidelines; (4) Considers common treatment obstacles and how to overcome them; (5) Discusses strategies for increasing patient motivation and adherence; and (6) Illustrates the method with an in-depth case example. New to the third edition are chapters on mindfulness meditation, neurofeedback, EMDR, breathing retraining, heart rate variability biofeedback, exercise therapy, and Qigong. Finally, Part III explores applications in mental health, behavioral medicine, and sport psychophysiology (another new topic in this edition), shedding light on which approaches are most suitable for particular problems. The concluding chapter reviews the clinical research literature and offers clear recommendations for improving outcomes. This timely, authoritative book is an indispensable resource for clinical and health psychologists, psychiatrists, social workers, counselors, nurses, and other professionals interested in learning and using stress management techniques. It will serve as a text in graduate-level courses in stress management, behavioral medicine, social work in health care, and related areas.

Abstract:
Eye movement desensitization and reprocessing (EMDR) has been established as an efficacious therapy for posttraumatic stress disorder (PTSD). The working mechanism of the procedure is, however, still partly unknown. It is therefore important to explore the physiological effects of eye movements and alternative bilateral stimulation. This article describes our research on the effects of eye movements during authentic EMDR sessions of chronic PTSD in refugees with war and torture experiences and places this research in the context of other findings. The findings point to definite physiological effects of eye movements; namely a dearousal with increased finger temperature and changes in the balance between the parasympathetic and sympathetic autonomous nervous systems.

Abstract:
Behandlung psychotraumatischer belastungsstörungen mit EMDR
Uns interessierte die Frage, ob die EMDR-Behandlung bei Patienten mit Posttraumatischer Belastungsstörung (PTSD) neben einer Symptomreduktion auch mit einer verbesserten psychophysiologischen Regulationsfähigkeit einhergeht. 15 Patienten (9 w, 6 m) mit PTSD nach Einzeltraumatisierung wurden vor und nach einer EMDR- Behandlung sowie in einer 6-Monate Katamnese per Fragebogen (PDS, IES, STAI, SCL-90-R) sowie mit psychophysiologischen Parameter (HR, HRV) während Konfrontation mit der individuellen traumatischen Erinnerung (Traumaskript) untersucht. Im Vergleich Prä-/Post, sowie Prä-/Katamnese kam es zu einer signifikanten Abnahme der Beschwerden in allen Symptombereichen. Gleichzeitig konnte nach Behandlung und in der Katamnese eine signifikante Verminderung des Anstiegs der Herzfrequenz während Konfrontation mit dem Traumaskript beobachtet werden. Der HF-Anteil der Herzratenvariabilität als Indikator für den Parasympathikotonus nahm im Vergleich Prä-/Katamnese unter Ruhebedingungen sowie während Traumaskript signifikant zu. Die EMDR-Behandlung erwies sich als wirksam hinsichtlich einer Reduktion der traumaassoziierten Symptomatik und einer Reduktion des psychophysiologischen Arousals bei Konfrontation mit der belastenden Erinnerung. Die Zunahme der HRV im Behandlungsverlauf im Sinne eines höheren Parasympathikotonus lässt auf eine Verbesserung der psychophysiologischen Regulationsfähigkeit schließen.

Our question was whether PTSD-patients would show a decrease of trauma associated symptoms as well as improved psychophysiological regulatory capacities after EMDR-treatment. 15 patients (9 female, 6 male) with PTSD after single traumatizations underwent psychometric assessment including questionnaires (PDS, IES, STAI, SCL-90-R) and psychophysiological variables (HR, HRV) during presentation of their individual trauma script before and after treatment and in a 6-month follow-up. Pre-/post as well as pre-/follow-up comparison showed significant decreases in all symptom measures. At the same time HR acceleration during trauma script decreased significantly after treatment. HF-HRV, an indicator for parasympathetic tone, increased significantly during baseline as well as during trauma script in pre-/post comparison. EMDR treatment led to an effective and lasting symptom reduction as well as to a reduction of the psychophysiological arousal associated with the traumatic memory. Enhancement of HRV after treatment in terms of a higher parasympathetic tone might be the result of improved psychophysiological regulatory capacities after successful EMDR treatment.

Abstract:
EMDR has in its short time of existence become an established therapy treating PTSD. The importance of the eye movement (EM) has so far been difficult to demonstrate, given that data supporting possible relationships between physiological variables and the therapeutic effect while conducting EM has not yet been recorded. Although theories have been presented, there is no data to support them. Our dismantling case study presents the first preliminary results from actual treatment studies and compares them with suggested theories. The results are based on three EMDR sessions treating a refugee diagnosed with chronic PTSD. In each session, heart rate, skin conductance, finger temptation, EMG, expiratory carbon dioxide, and oxygen saturation were recorded continuously. Our data demonstrates a strong and consistent trend toward an altered physiological state during EM. The directions of physiological change were consistent in all sessions. All alterations indicated raised activitry in the parasympatic nervous system and were thus compatible with the Stickgold hypothesis suggestion that EMDR increases processing of unprocessed traumatic memories through activation of cholinergic systems. Despite the small scale of our study, these novel and interesting findings generate a new fore further research. Our psychophysiological approach appears to be a promising path.
