Abstract:
What exactly happens on a neuroendocrine level in acute, chronic and complex PTSD? Is there a relationship between this unusual neuroendocrine profile and a number of medical disorders of unknown origin which, often, do not respond to traditional symptomatic medical treatment? This seminar will review and examine the results of extensive neuroendocrine research relative to these trauma-induced disorders. The data from these research bases will be integrated with neuroendocrine research findings regarding autoimmune compromises associated with chronic trauma. Anomalous conditions, such as Fibromyalgia, Chronic Fatigue Syndrome, Reflex Sympathetic Dystrophy (RSD), Systemic Lupus Erythematosis, Hashimoto’s Thyroiditis, Sjogren’s Syndrome, and Rheumatoid Arthritis will be examined. This presentation will illustrate the neuroendocrine and causal relationship between the various forms of PTSD and these medical disorders. Accordingly, the implications for treatment will be examined.

Abstract:
Respiratory Sinus Arrhythmia: Insights into Autonomic Function in PTSD: Studies of cardiac responses to trauma-related cues have defined the mainstream of laboratory research in posttraumatic stress disorder. Examinations of respiratory sinus arrhythmia now challenge the view that exaggerated sympathetic tone and reactivity provide a sufficient account of the autonomic abnormalities seen in this diagnosis.
Alterations in autonomic tone during trauma therapy with EMDR: It has been hypothesized that EDMR, by pairing stimuli that evoke divided attention with exposure to trauma memories, elicits repetitive orienting responses followed by enhanced parasympathetic tone, resulting in significant within-session psychophysiological de-arousal. We monitored 10 standard EMDR treatments for PTSD (55 sessions) with impedance cardiography. Heart rate (HR), parasympathetic tone (RMSSD), sympathetic tone (PEP), and respiration rate (RESP) were assessed. Markers were set at the onset of every stimulation/exposure period (N = 811). Effects within and across stimulation sets were examined. An orienting response, with associated sharp increase of parasympathetic tone and significant decrease of HR, was found at stimulation onsets. During ongoing stimulation, sympathetic arousal increased while parasympathetic tone decreased, responses consistent with stressrelated arousal during trauma exposure. However, across entire sessions there was a significant pattern of psychophysiological de-arousal, evidenced by progressively decreasing HR and increasing RMSSD. These findings suggest EMDR is associated with distinct patterns

Abstract:
Eye Movement Desensitisation and Reprocessing (EMDR) is increasingly being recognised as a coherent therapeutic procedure in the treatment of Post Traumatic Stress Disorder (PTSD) and other anxiety disorders, yet we still do not fully understand by which process or mechanisms it might work. We consider a number of models implicating orienting or investigatory reflexes as a significant contributor to the success of EMDR as a treatment method. A series of experiments were designed to test the predictions derived from these models, examining the physiological effects of eye-movements following auditory challenge compared to an eyes-stationary condition. A significant physiological de-arousal effect is observed in conditions requiring eye-movements similar to those used in the EMDR protocol. We go on to consider the implications for this de-arousal effect in the treatment of PTSD and present preliminary data from a case series designed to examine the unique contribution of EMDR when used with treatment resistant clients. A range of psychometric and psychophysiological process and outcome measures were utilised in this study, providing a detailed evaluation of change over the course of the treatment design. Specialised software was developed for use in this study, in addition to a computerised test and software is provided, along with data obtained from this test.

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.

Language: English

Format: Journal

Abstract:
Explanations for the effects of the rapid eye movements induced during Eye Movement Desensitization Reprocessing (EMDR; Shapiro, 2001) have drawn upon an analogy with the eye movements of REM sleep (Kuiken, Bears, Miall, and Smith, 2002). An extension of that analogy posits two orienting systems, one involving threat-fear related mnemonic contextualization and another involving loss-pain related monitoring of conflicting response alternatives. In a study involving individuals who had recently experienced significant loss or trauma, we found that experimentally induced saccadic eye movements decreased reaction times to unexpected stimuli among those reporting traumatic distress (characterized by hyperarousal and intrusive thoughts) and increased reaction times among those reporting separation distress (characterized by vivid reminiscences and the sense of a foreshortened future). Also, we found that saccadic eye movements increased the perceived strikingness of metaphoric sentence endings among those reporting amnesia for events related to either loss or trauma. The eye movements of both EMDR and REM sleep may differently affect the attentional and cognitive reorienting activity of those living with the consequences of loss or trauma. These differences may be evident in their waking reflections and in their dreams.

Abstract:
Researchers have published evidence supporting both the “working memory“ and the “REM/Orienting Response“ hypotheses as mechanisms underlying the documented treatment effects of EMDR on patients with posttraumatic stress disorder. Hornsveld et al. (2011) provide additional evidence of the impact of eye movements (EMs) on aspects of positive memory recall, but overstate their findings relevance to resource development and installation (RDI: Korn & Leeds, 2002) and to the interhemispheric interaction hypothesis (Propper & Christman, 2008). Most likely multiple mechanisms underlie the observed effects of EMDR and RDI. The needed RDI test is to randomly assign patients with Disorders of Extreme Stress not Otherwise Specified with measured coping difficulties to alternate conditions: one an RDI procedure without bilateral (or other distracting) sensory stimulation and one with bilateral EMs.

Language: English

Format: Conference

Abstract:
EMDR therapy is widely recognized as an empirically supported trauma treatment and was given an “A” rating in the most recent practice guidelines of both the DVA/DOD and the International Society for Traumatic Stress Studies. Meta-analytic findings report similar effect sizes for trauma-focused cognitive behavioral therapy (TF-CBT) and EMDR therapy in the treatment of posttraumatic stress disorder (PTSD). However, there are distinct differences between the two modalities in both theory and practice. Unlike TF-CBT exposure therapies, with EMDR therapy there is only intermittent attention to the index trauma, homework is not required and detailed descriptions of the memory are not needed. Further, the eye movement component has been the subject of more than 20 randomized controlled trials that have reported positive effects supporting both working memory and orienting response/REM hypotheses. These effects include a rapid decrease in physiological arousal and negative emotion, as well as increased episodic memory retrieval and recognition of true information. Videotaped clinical sessions will illustrate these findings, as well as the differences between EMDR therapy and prolonged exposure.

Format: Dissertation/Thesis

Abstract: Eye movement desensitization and reprocessing (EMDR) is a widely applied therapy for posttraumatic stress disorder (PTSD). In this therapy patients make eye movements while recalling traumatic memories. It is suggested that EMDR taxes working memory and this reduces ratings of the vividness and emotionality of traumatic memories. Although this has been studied extensively for the effectiveness of eye movements, research on bilateral beeps is scarce. Whit a sample of 42 students we compared the effectiveness of eye movements and bilateral beeps. Results indicate that eye movements are more effective in reducing vividness and emotionality of negative memories. Indirectly testing a mechanism proposed by the Working Memory Theory, we found that participants with a larger working memory focused their attention more on the memory as compared to students with a smaller working memory. In sum we conclude that bilateral beeps are inferior to eye movements in the reduction of vividness and emotionality of memories

Eye Movement Desensitization and Reprocessing (EMDR) represents a promising approach to treatment of posttraumatic stress disorder. The empirical findings provide evidence for the effect of EMDR on decreasing of subjectively perceived vividness and emotional burden of autobiographic memories and on reducing arousal of the autonomic nervous system by shifting the balance towards parasympathetic activation. Recent hypotheses suggest that the effects of EMDR rely on neurobiological mechanisms employed in dual focus attention, orienting reflex and REM sleep. This reprocessing seems to provoke a specific neurobiological response that makes the information processing in central nervous system more efficient, particularly in individuals with PTSD [Author Abstract].

Language: English

Format: Conference

Abstract:
Methods: Sixty-two non-clinical participants with negative autobiographical memories received a single EMDR session that involved fixed or varied rate eye movements, or exposure without eye movements. 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 (SUDs) than EMDR-without eye movements. Psycho physiological measures were continuously recorded throughout each session. Results: 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. Conclusion: These findings indicate that eye movements in EMDR are beneficial, and are coupled with distinct psycho physiological changes that may aid in the processing of negative memories. Implications for clinical practice, directions for future research, and the importance of building bridges between East & West whilst conducting EMDR research will also be discussed.

Abstract:
"The Body Keeps the Score" (B. v.d. Kolk, 1996) Clients who suffer from traumatic stress are often afraid about disturbing and painful somatic symptoms. Structural dissociation alienates from body reactions. Nevertheless it is the body that "holds" the discomfort and painful memory of neglect and violence. Trauma Survivors tend to perceive their body as hostile. They suffer from Alexithymia deficiency of interpreting the meaning of body reactions and muscle activation. Trauma Survivors are easily irritated and tend to react with rage on very slight provocations and freeze when they are frustrated. Even minor problems cause fear and helplessness. The Polyvagal Theory (S. Porges 2010) proves the neurological aspect of behavioral patterns. Neurozeption describes how we perceive others in a neurological way. Certain behavioral patterns are established through life experiences. This research underlines Francine Shapiros AIP model and confirms the importance of a body orientated approach. We know that experiencing the effect of eye movement -‐ and other bilateral stimulation, is a gentle and powerful way to bring the voice of the body into the therapeutic space. EMDR helps to integrate cognitive, emotional and body sensations. Using movement and body orientated skills in difficult processes f.e. with severely and/or early traumatised clients, even enhances the effect of EMDR. Content of the Workshop: Short theoretical implications: Polyvagal Theory and AIP Model. Stabilisation and Movement -‐ creating a „Moving Container“: How to create a safe place of relationship and attachment between the client and the therapist by using movement and bodywork? The body is the most powerful resource: How to use movement to access this power. How to recognize and dissolve dissociation by body and movement awareness. EMDR Process and Movement : How to widen the „window of tolerance“ by using movement and deeper levels of body consciousness. Adding a fourth level of attention to the EMDR process: cognition -‐ emotion -‐ body scan -‐ movement. Movement and reflex feedback as interweave technique in difficult processes. Methods used in the Workshop: Lecture and Video Presentation. Practical demonstration of some movement orientated techniques. Discussion.

“El cuerpo lleva la cuenta” (B. v.d. Kolk, 1996), los clientes que sufren de estrés traumático tienen a menudo miedo sobre sus síntomas somáticos preocupantes y dolorosos. La disociación estructural aliena las reacciones del cuerpo, sin embargo es el cuerpo el que “mantiene” el disconfort y el recuerdo doloroso de negligencia y violencia. Los supervivientes a un trauma suelen tender a percibir su propio cuerpo como hostil. Sufren de Alexitimia, deficiencias para interpretar las señales corporales y la activación muscular. Son fácilmente irritables y tienden a reaccionar con ira, con leves provocaciones y se “congelan” cuando están frustrados. Incluso problemas de fuerza menor causan miedo y desesperanza. La teoría polivagal (S. Porges 2010) prueba el aspecto neurológico de los patrones de comportamiento. La neurocepción describe cómo percibimos a los otros desde un punto de vista neurológico. Ciertos patrones de comportamiento están establecidos a través de las experiencias vitales. Esta investigación se basa en el modelo SPIA de Francine Shapiro y confirma la importancia del enfoque orientado al cuerpo. Sabemos que al experimentar el efecto de la estimulación ocular, y otras estimulaciones bilaterales, es un camino poderoso y suave para traer la voz del cuerpo dentro del espacio terapéutico.

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]

Abstract:
A core feature of post-traumatic stress disorder (PTSD) is hypervigilence to threatening material. This study measured processing of threat material in PTSD with simultaneously acquired initial eye movements and electrodermal activity, following presentation of threatening and neutral words. Ten PTSD subjects and 10 controls were presented with 4 words in parafoveal range. On trials in which a threat word was present, PTSD subjects demonstrated initial eye fixations on the threat word more than controls. PTSD subjects also demonstrated more orienting responses on all trials than controls. These results suggest that processing of threat information in PTSD can be usefully investigated with convergent psychophysiological methodologies.

Language: English

Format: Journal

Abstract:
Background: Eye movement desensitisation and reprocessing (EMDR) has attracted controversy and has led to publications covering a wide range of psychological problems treated by EMDR, in particular, PTSD. There is growing clinical evidence of the effectiveness of EMDR, but a lack of a convincing theoretical basis to explain its rapid effect. Method: This paper argues that a combination of Pavlovian and Darwinian theory provide a theoretical explanation for the therapeutic effectiveness of EMDR. Results: We suggest that the investigatory component of the orienting reflex is an evolutionary development enabling organisms to assess their environment for both opportunities and threats. We propose that EMDR is rapidly effective because it is a clinical method of Pavlovian conditioning by which the positive visceral element of the investigatory reflex can be paired with clinically-induced noxious memories to remove their negative affect. Conclusion: Compared with established forms of treatment for PTSD, EMDR is rapid, with resulting clinical and economic benefits. Our suggested theoretical basis for EMDR has implications for further explanatory research and for developments in EMDR treatment. [Author Abstract]

Language: English

Format: Journal

Abstract:
Eye Movement Desensitization Reprocessing (EMDR) is a controversial treatment for PTSD that requires clients to make rapid eye movements while revisualizing a traumatic event. Although seemingly effective, the process by which EMDR exerts its effects is poorly understod. We propose that EMDR's eye movements facilitate the orienting response, i.e., the attentional adjustment to unexpected stimuli. Since the orienting response has been implicated in spontaneous transformations of dream content during REM sleep, we reasoned that, similarly, activation of the orienting response during EMDR may facilitate content transformations in traumatic memories. To examine this hypothesis, 25 undergraduates completed 20 seconds of eye movements or 20 seconds of visual fixation before each of two tasks: (1) a covert visual attention task, in which a cue indicated the likely position of a subsequent target, and (2) a sentence rating task, in which sentences with either metaphoric or non-metaphoric endings were rated for strikingness. Repeated measures ANOVAs indicated that the eye movement manipulation facilitated attentional adjustments to targets presented in invalidly cued locations and increased the extent to which metaphoric sentence endings were found striking. Together these results suggest that the eye movements in EMDR induce attentional and semantic flexibility, thereby facilitating transformations in the client's narrative representation of the traumatic event. The implications of these findings for theories of dream formation and metaphor comprehension are also considered. [Author Abstract]

Abstract:
Objectives: Theoretical models implicating the orienting reflex as an explanatory mechanism in the eye-movement desensitization and reprocessing (EMDR) treatment protocol are contrasted and tested empirically. We also test whether EMDR effects are due to a distraction effect. Design: A repeated measure design is used in two experiments. The first experiment employed two independent variables, eye condition (moving vs. stationary) and tone (a pseudo-randomized series of low and high intensity tones). In Expt 2, eye condition was replaced by attentional demand conditions (low or high). In both cases, electrodermal responses served as the dependent variable. Method: Participants were recruited from the Psychology Department at Cardiff University. In Expt 1, participants were required to either pursue a moving stimulus following auditory challenge or engage in an eyes-stationary task. In Expt 2, the task following auditory challenge required participants to identify specific items from letter strings in low and high attentional demand conditions. Results: Lower levels of electrodermal arousal were identified in tasks eliciting eye movements, compared to no eye movements. This effect was not due to the attentional requirements of the task. Conclusions: Eye movements following auditory challenge result in an effect of psychophysiological de-arousal. This supports the reassurance reflex model of EMDR proposed by MacCulloch and Feldman (1996).

Abstract:
Eye movement desensitization and reprocessing can reduce ratings of the vividness and emotionality of unpleasant memories--hence it is commonly used to treat posttraumatic stress disorder. The present experiments compared three accounts of how eye movements produce these benefits. Participants rated unpleasant autobiographical memories before and after eye movements or an eyes stationary control condition. In Experiment 1, eye movements produced benefits only when memories were held in mind during the movements, and eye movements increased arousal, contrary to an investigatory-reflex account. In Experiment 2, horizontal and vertical eye movements produced equivalent benefits, contrary to an interhemispheric-communication account. In Experiment 3, two other distractor tasks (auditory shadowing, drawing) produced benefits that were negatively correlated with working memory capacity. These findings support a working-memory account of the eye movement benefit in which the central executive is taxed when a person performs a distractor task while attempting to hold a memory in mind.

In Experiment 2, horizontal and vertical eye movements produced equivalent benefits, contrary to an interhemispheric-communication account. In Experiment 3, two other distractor tasks (auditory shadowing, drawing) produced benefits that were negatively correlated with working-memory capacity. These findings support a working-memory account of the eye movement benefits in which the central executive is taxed when a person performs a distractor task while attempting to hold a memory in mind.

Abstract:
A new interweave technique is described for when patients are slow to desensitize or when they are emotionally overwhelmed during EMDR treatment. The interweave is comprised of two parallel components: a finger-touching go/no-go tracking task as well as a semantic priming task. The theoretical rationale for the finger-touching task is explained relative to neuroimaging studies of the anterior cingulate cortex and other areas. The rationale for the semantic priming task is explained relative to research about dopaminergic activation projecting from the ventral tegmentum as well as novelty generated orienting responses. A two-stage model is proposed for constructing effective EMDR stimulation techniques.

Format: Conference

Abstract:
This presentation will introduce the basics of EMDR therapy and provide an overview of treatment. Both the theoretical foundation and recent research findings will be explored. EMDR is an evidence-based psychotherapy supported by more than 20 randomized controlled studies. Meta-analyses have indicated that the effects of EMDR on PTSD symptoms are comparable to those of trauma-focused CBT. However, EMDR therapy does not require homework, sustained arousal, detailed descriptions of the index trauma, or extended exposure to the event. While the eye movement component has been the subject of controversy, in the past decade an additional 20 randomized trials have evaluated the eye movements and demonstrated significantly superior effects compared to “exposure-only” conditions. The eye movements have been shown to (a) decrease the emotionality and vividness of memories, (b) create physiological relaxation responses, (c) facilitate access to associative memories and (d) lead to an increase in recognition of correct information. Two dominant theories regarding the role of the eye movements have emerged: (1) disruption of working memory and (2) elicitation of an orienting response. The research and clinical implications will be examined. The goals of this presentation parallel those of the conference itself by allowing participants to evaluate ways in which EMDR therapy offers innovations in both conceptualization and clinical treatment. These innovations include ways to support therapy retention and increase stability for those clients ordinarily considered too fragile to tolerate memory processing. Outreach can also be increased through the use of consecutive-day trauma treatment. Relevant research will be reported on the use of EMDR therapy with diverse populations. Participants will learn how the adaptive information processing theory that guides EMDR therapy practice offers a reconceptualization of (a) psychopathology, (b) therapeutic change, (c) the therapy relationship, (d) preparation for processing and (e) the multiple methods included in the therapy. The presentation will provide participants with the theoretical basis for EMDR therapy, an overview of the eight treatment phases, the three-pronged selection of processing targets, pertinent research, as well as applications to the full range of trauma victims. Videotaped sessions will demonstrate diverse treatment effects and provide participants with comparisons to other research-supported trauma treatments. 1-Describe the relevant research findings 2-Identify the components of the standard EMDR therapy three-pronged approach to processing 3-Contrast EMDR therapy with other empirically supported trauma treatments

Abstract:
We tried to “dissect” the EMDR method in the component desensitization through rapid eye movement (EMD), that is also the original part, to explain the neurophysiological functioning, Charney et al, say that a lot of persistent symptoms of PTSD are caused by an elevate arousal of NVS, particularly due to the increase of norepinephrine. Others hypothesize, again, that EMDR method is rapid because it is based on Classic Conditioning. Pavlov found that every stimulus of environment causes to the organism (animal or human) an immediate orienting response due to the arousal of the Autonomic Nervous System. In this situation the animal begins to look around moving its eyes laterality (as it happens during ocular movements of EMD); if it perceives a danger in the environment it stimulates a visceral negative response (hyperactivation that means fear) that leads an an avoidance behaviour (stiffening) and/or fighting. In other cases it causes a visceral positive response (de-arousal process that means reassurance) that leads to an approach behaviour through interaction or exploration.
The EMD should produce an orienting reflex in the patient in a protective sitaution like a psychotherapeutic setting; that means an important reduction of neuro-vegetative nervous system activity (dearousal) and some visceral positive response. We propose an experimental design with a single subject (ABACADA) by interruption treatment and by monitoring Neurophysiological functions through biofeedback instruments to test this neurophyiological hypothesis.

Abstract: Desensitisation and Reprocessing) and REM sleep. [Background] Eye movement desensitization and reprocessing (EMDR) is a new innovative treatment with a high success rate for psychological disturbances rooted in traumatic memory. However, the neurophysiological mechanisms of EMDR have not yet been elucidated. Why is saccadic eye movement effective for the reprocessing of previously established conditioned reflex? [Aims] The present research analysed (i)the topographical changes of EEG (and ERP) and REM sleep after EMDR treatment, and (ii)the subjective units of emotional distress (SUDs) and VOC. [Methods] Subjects (13 males and 20 females) were assigned to three groups according to varied conditions (control, provocational, and EMDR), and engaged in sets of horizontal saccadic-eye movements lasting approximately 30 seconds per set. Topographical changes of EEG and ERP activities were recorded from 14 placements over frontal, central, parietal, temporal and occipital scalp locations in the international 10-20 system with linked mastoides (A1-A2). Electrodes were also placed on the lateral canthus and above the supercillium of the left eye in order to measure the electrooculographic and electromyographic responses. [Results and Conclusions] The statistical significance of topographical EEG differences and REM densities during the pre-0post EMDR treatment situations, were evaluated using an ANONA and Mann-Whitney U test. The neurophysiological and psychological data indicate that the density of eye movement during REM sleep increased after provocation and EMDR, and the left frontal activities might indicate a treatment efficacy. It supports the hypothesis is that REM sleep is intimately involved with the mechanisms of emotional and memory reprocessing.

Abstract:
In this article we review the current literature surrounding needle phobia, concentrating on clinical symptoms, aetiology and treatment options. Clinical symptoms include sudden increase in heart rate and blood pressure on exposure to needles followed by an immediate slowing of the heart and decrease in blood pressure (vasovagal reflex). The various schools of thought surrounding aetiology of this condition include biological, psychological and psychodynamic theories. Treatment options vary from simple education and reassurance to medication and specific behavioural approaches. Consideration should be given to past trauma associated with the phobia and relevant family factors. Careful clinical assessment will not only identify the problem but will also help to indicate appropriate treatment options.

Abstract:
Eye Movement Desensitization and Reprocessing represents a promising approach to treatment of posttraumatic disord-ers. The specific factors underlying its effectiveness rely particularly on bilateral stimulation, which seems to provoke a specific neurobiological response during traumatic recall particularly in individuals with PTSD. The empirical findings provide evidence for the effect of BLS on autonomic nervous system shifting the balance towards parasympathetic acti-vation (reducing arousal) as well as the effect on subjectively perceived vividness and emotional burden of autobiograph-ic memories (decrease). The most credible hypotheses derive the effects from neurobiological mechanisms employed in dual focus attention, orienting reflex and REM sleep. Further research is needed to explore the processes included in the EMDR therapy in more detail and clarify the role of bilateral stimulation.

Abstract:
The clinical phenomena of the conduct of EMDR and Thought Field Therapy were interpreted in light of concepts in the field of classical conditioning with emphasis on the orienting reflex and its external inhibiting effects on conditioned responses. A model was proposed using the temporary suppression through external inhibition of the fear and avoidance conditioned responses to disturbing memories. The clinically helpful effect proposed is the emergence of previously suppressed competing responses to the troublesome memories. Those newly emerged responses are responsible for spontaneous cognitive restructuring of the meaning attribution of the memories, thus lowering SUDS ratings. [Author Abstract]

Abstract:
Introduction: Eye movement desensitization and reprocessing (EMDR) is a relevant technique to improve post-traumatic stress disorder (PTSD) symptoms. Objectives: To compare the electrophysiological profile of patients suffering post traumatic stress disorder before and after EMDR treatment. Aims: The authors are in search of a specific event-related brain potentials profile for post-traumatic stress disorder (PTSD). Methods: Eight patients suffering from post-traumatic stress disorder (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. Results: Psychometric assessment revealed a marked improvement of the PTSD symptoms after treatment. Compared to a control group that underwent sham treatment, ERPs of the patients showed morphological changes in the post-treatment recording, suggesting a reduced orienting to novel stimuli and reduced arousal level after the treatment. Conclusions: EMDR therapy provides clinical improvement and event-related potentials changes that could be used in clinical practice as an interesting marker to assess diagnosis and successful treatment of PTSD.

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:
In 1996, the existence of a cerebral de-arousal reflex was predicted. A suite of computer programs has been developed to administer EMDR and take sequential measurements of changes in PTSD symptoms. Physiological data show that computer-induced eye movements produce de-arousal, causing attitude, and mood changes within and between EMDR treatments. Theories to explain the variation in symptomatology in PTSD in terms of individual differences in "the strength of the nervous system" and the mechanism of EMDR are presented.

Abstract: The aim of the study was to explore the working mechanism of the bilateral stimulation component in EMDR in relation to current hypotheses. Physiological hypotheses (of orienting response and relaxation response) were tested in an analogous experimental setting. Moreover, the clinical advice to use different stimulation speeds for different phases of EMDR was examined at the autonomic level, exploring two different speeds of eye movements. In a within-subject design 42 female students performed 7 short sets each of rapid eye movements (1 Hz), slow eye movements (0.3 Hz) and eye fixation while engaging in negative autobiographical memories. Order of the tasks was counterbalanced. Electrooculogramm (EOG), electrocardiogramm, electrodermal activity and distal pulswave were recorded continuously. Skin conductance level (SCL), heart rate (HR), heart rate variability (RMSSD) and pulse wave transit time (PWTT) were calculated. Performance of the eye movement tasks were controlled through EOG. All three conditions showed a clear-cut de-arousal at stimulation onset, which was 30 indicated by a decrease in HR and SCL and an increase in RMSSD and PWTT. That means, fast and slow eye movements as well as eye fixation initiated a moderate, but clear relaxation response with increased parasympathetic and reduced sympathetic activity. These results suggest that the speed of eye movements do not influence autonomic functions. Furthermore, the results of this study do not support most of the current hypotheses regarding the working mechanism of the bilateral stimulation in EMDR. Alternative explanations are discussed

Abstract:
Negative autobiographical memories are effectively treated using EMDR with patients making eye movements during the recall of negative autobiographical memories. While several studies have measured the effects of different types of stimulations, we are not aware of any research assessing the combined effects of two different stimulations applied simultaneously during the recall of the event. For this preliminary study involving 15 adult patients from both sexes, 4 EMDR counselor therapists measure 17 symptoms of the list proposed by Weimann (1968)). Each patient is evaluated before, during and at the end of each session. We control the effect of the sequence of one versus two types of stimulations by assigning each patient to both conditions but in a random way: (a) first target first session with one type of stimulation following with a second target first session, including two types of stimulation; (b) the inversed sequence. We compare the mean level intensity of each symptom (within factor) between one type vs. two types of stimulations (between factor) using the Anova and the t- Student tests. We hypothesize that an attenuation of intensity of the stress symptoms occurs when the patient is treated simultaneously with two types of bilateral stimulation (eye movements and tactile stimuli), compared to one (eye movements). The paper presents preliminary data, as well as a discussion of the results in the light of the theory of the working memory (Andrade et al.1997) and the reassurance reflex model of EMDR proposed by MacCulloch and Feldman (1996).

Los recuerdos autobiográficos negativos son tratados con efectividad usando el EMDR con pacientes a través del movimiento ocular de ojos durante el acceso al recuerdo negativo autobiográfico. Mientras muchos estudios han medido dos tipos diferentes de estimulación, no estamos al corriente de ninguna otra investigación que informe de los efectos combinados de los dos tipos de estimulación aplicada simultáneamente durante este acceso al recuerdo del evento. En este estudio preliminar contamos con los datos de 15 pacientes adultos de ambos sexos, 4 consultores EMDR midieron 17 síntomas de la lista propuesta por Weimann (1968). Cada paciente era evaluado antes, durante, y al final de cada sesión. Controlamos los efectos de una secuencia en función de los 2 tipos de estimulación, asignando a cada paciente ambas condiciones pero de manera aleatorizada: (a) Primer recuerdo Diana, primera sesión con un tipo de estimulación seguido de un Segundo recuerdo de la primera sesión incluyendo dos tipos de estimulación; (b) invertimos la secuencia anterior. Comparamos la media del nivel de intensidad de cada síntoma (dentro del factor) entre un tipo y dos tipos de estimulación (entre factores) usando cálculos estadísticos de Anoia y una t-‐Student para los resultados. Nuestra hipótesis es que ocurrirá una atenuación de los síntomas de estrés cuando el paciente es tratado simultáneamente con dos tipos de estimulación bilateral (movimientos oculares y estímulos táctiles), comparados con la de un solo tipo (Movimientos oculares). Este artículo presenta el análisis preliminar de los datos, así como la discusión de los resultados en línea con la teoría de la memoria de trabajo (Andrade y cols 1997) y la reafirmación del modelo refractario del EMDR propuesto por MacCulloch y Feldman (1996).

Abstract:
Objective: Dual attention stimulation seems to provoke orienting response like patterns of psychophysiological deactivation during “real-life” EMDR treatment sessions (Sack et al, in review). Objective of this study was to investigate the association of psych-physiological effects during dual attention stimulation with treatment outcome as measured by questionnaire and by psychophysiological reactions during presentations of an individualized trauma script.
Methods: A total of 24 EMDR treatment sessions from 10 patients with PTSD were monitored applying impedance Cardiography. The onset of every stimulation/exposure period was marked and effects within and across stimulation sets on heart rate (HR), heart rate variability (RMSSD), pre-ejection period (PEP) and respiration rate were examined. Heart rate reactivity during presentation of an audiotaped trauma script was measured at beginning of every session and additionally one week before the first session and one week after the last treatment session. Statistical correlations between both subjective (Impact of Event Scale, SUD) and objective (heart rate reactivity) measures of treatment outcome with psychophysiological changes during session (orienting response at beginning of stimulation, slope of HR) were computed.
Results: A significant reduction of trauma-related symptoms was noticed over the course of EMDR treatment: (IES one week pre: 61.2(SD 10.9), IES pre: 55.4(SD 19.0), IES post: 13.3(SD 12.2), F(2,27); 32.6, p < .001). Subjective distress during trauma script decreased significantly (SUD one week pre: 6.6(SD 1.4), SUD pre: 6.9(SD1.4), SUD post: 2.1(SD 1.7); F(2, 27); 31.5, p < .001). The statistical analysis of physiological variables is currently in process. Results will be presented at the conference.
Conclusions: The results of this study will allow further insights into the working mechanism of EMDR.

Language: English

Format: Journal

Abstract:
A theoretical model is proposed to explain desensitization during Eye Movement Desensitization and Reprocessing (EMDR) as resulting from the reversal of reciprocal suppression of cognitive processing in the anterior cingulate cortex (ACC). Dual-attention and error monitoring are known to activate dorsal regions of the ACC that mediate metacognitive processing. Neuroimaging research has produced evidence that cognitive areas in the upper ACC may reciprocally suppress affective processing in the lower areas and vice versa. It is therefore proposed that the original eye-to-finger tracking task of EMDR may achieve its therapeutic effect by using error monitoring to reverse suppression of the upper ACC by the lower ACC. Contributions to EMDR effectiveness from resource installation and novelty-driven orienting reflexes may also influence ACC functioning. A distraction effect is proposed to be a negative and potentially disruptive by-product of very interactive stimulation tasks. A semantic priming procedure is suggested to limit distraction effects during more interactive forms of stimulation. [Author Abstract]

Format: Dissertation/Thesis

Abstract:
A dual-task during recall of an emotional memory reduces its vividness and emotionality, which may be due to both tasks competing for limited working memory (WM) resources. The dose-response relationship between WM taxing during memory recall and its benefits was investigated. Additionally, the fear-potentiated startle reflex was measured to obtain more objective information about the expected decrease in vividness and emotionality. Participants recalled negative and positive memories while performing no dual-task, a moderately taxing dual-task (eye movements), or a very taxing dual-task (Tetris), after which vividness, emotionality and the startle reflex were measured. Compared to no dual-task, eye movements and Tetris similarly decreased image vividness and/or emotionality, and the startle reflex. The findings suggest a WM account of EMDR, which indicates that a concurrent task is beneficial because it taxes WM during memory recall; and that WM taxing during memory recall and its benefits are not linearly related.

Abstract:
Our lab specialized in the study of behavioral/cognitive changes following focal brain lesions. Phenomena were once considered mere curiosities - such as phantom limb, anosognosia and synesthesia - have now become "main stream" partly as a result of the work done by us and many colleagues throughout the world. This lecture will focus on disturbances in body image, phantom limbs, anosognosia (denial of paralysis) and somatoparaphrenia (denial of ownership of a limb). A new theory will be advanced to account for these, especially the latter two in terms of asymmetries between the two hemispheres "coping styles"; the left involved in "Freudian defences" aud the right playing thc role of a "devils advocate" or anomaly detector. The spectrum of normal and abnormal personality styles and behavior emerges from a push-pull antagonism between these two opposing tendencies. Vestibular stimulation through calorie cold-water irrigation produces eye movements (nystagmus) and shifts the balance between the two hemispheres during the "orienting" response and produces profound shifts in mood and/or body image. We found that the procedure "de-represses" apparently repressed memories in patient with denial (anosognosia) and there is an obvious analogy here with the therapeutic claims of EMDR. The possibility that bipolar disorder may be based on such alternation between hemispheres was first proposed by us in 1996 and has received some support. Consequently caloric nystagmus might potentially be useful in treating disorders such as bipolar, post-traumatic stress, complex regional pain type 1, and other neuro-psychiatric disturbances as outlined briefly in my book Phantoms in the Brain.
