Eye Movements Matter, But Why? Psychophysiological Correlates of EMDR Therapy to Treat Trauma in Timor-Leste

A conceptual framework for a neurophysiological basis of art therapy for PTSD

Post-traumatic stress disorder (PTSD) is a heterogeneous condition that affects many civilians and military service members. Lack of engagement, high dropout rate, and variable response to psychotherapy necessitates more compelling and accessible treatment options that are based on sound neuroscientific evidence-informed decision-making. Art therapy incorporates elements proven to be effective in psychotherapy, such as exposure, making it a potentially valuable treatment option. This conceptual paper aims to inform the neurophysiological rationale for the use of art therapy as a therapeutic approach for individuals with PTSD. A narrative synthesis was conducted using literature review of empirical research on the neurophysiological effects of art therapy, with supporting literature on neuroaesthetics and psychotherapies to identify art therapy factors most pertinent for PTSD. Findings were synthesized through a proposed framework based on the triple network model considering the network-based dysfunctions due to PTSD. Art therapy's active components, such as concretization and metaphor, active art engagement, emotion processing and regulation, perspective taking and reframing, and therapeutic alliance, may improve symptoms of PTSD and prompt adaptive brain functioning. Given the scarcity of rigorous studies on art therapy's effectiveness and mechanisms of alleviating PTSD symptoms, the suggested framework offers a neurophysiological rationale and a future research agenda to investigate the impact of art therapy as a therapeutic approach for individuals with PTSD.

A Stage 1 Pilot Cohort Exploring the Use of EMDR Therapy as a Videoconference Psychotherapy During COVID-19 With Frontline Mental Health Workers: A Proof of Concept Study Utilising a Virtual Blind 2 Therapist Protocol

Objective

The COVID-19 pandemic has had a major impact on the delivery of psychological treatment. Due to social distancing requirements, the provision moved to videoconferencing psychotherapy (VCP). There is a paucity of empirical data supporting the efficacy of EMDR therapy as a VCP. This stage 1 pilot study tested an EMDR therapy scripted protocol, such as Virtual Blind 2 Therapist (VB2Tr), on frontline mental health workers as a VCP regarding fitness for purpose, distinctiveness, relevance, and efficiency.

Methods

A total of 24 participants were recruited for the study. The design included a one-session treatment intervention with pre, post, 1-month, and 6-month follow-up (FU) measurements. This treatment session used a “Blind 2 Therapist” EMDR therapy scripted protocol as videoconference psychotherapy that involves non-disclosure of traumatic memory. The research explored the treatment effect on the core characteristics of trauma memory, including subjective disturbance, belief systems, memory intensity (MI), vividness, and levels of emotionality. Additionally, the research explored participants’ experiences of adverse and benevolent childhood experiences (ACEs/BCEs) during their childhood.

Results

Regarding the four tests, namely, fitness for purpose, distinctiveness, relevance, and efficiency, results are favourably suggesting potential clinical benefits of using EMDR as videoconference psychotherapy. Although this is a proof-of-concept study showing positive results, no clinical population or control group was used. The purpose of the study is to explore the potential for scalability toward a larger clinical trial. The treatment intervention was achieved irrespective of either ACEs/BCEs during childhood.

Conclusion

The research tentatively supports the case for EMDR therapy as a credible treatment when used as video conference psychotherapy and in using the Blind 2 Therapist protocol. However, more research is needed to scale toward a clinical trial.

Effects of rhythmic eye movements during a virtual reality exposure paradigm for spider-phobic patients

Rhythmic eye movements performed during eye movement desensitization and reprocessing (EMDR) therapy have been shown to evoke a physiological de-arousal pattern.

OBJECTIVES

Here, we examined whether the efficacy of a virtual reality exposure therapy (VRET) paradigm for phobic patients could be improved by adding rhythmic eye movements.

DESIGN

Spider-phobic patients (N = 53) were randomly assigned to either a group performing rhythmic eye movements or a control group undergoing exposure without such eye movements.

METHODS

During the VRET session, heart rate, electrodermal activity, eye movements, and subjective fear ratings were recorded. Participants underwent behavioural avoidance tests before and after treatment as well as a follow-up 10-14 days later. Questionnaire data were assessed before exposure and at follow-up.

RESULTS

There were clear treatment effects in both groups with almost no group differences (i.e., the subjective fear ratings and the skin conductance response).

CONCLUSIONS

Contrary to our expectation, the implementation of rhythmic eye movements during virtual exposure did not enhance the effectiveness of the treatment. However, the eye movement group did show a significantly lower heart rate during exposure compared with the control group which might indicate a less stressful treatment.

PRACTITIONER POINTS

One-session Virtual Reality Exposure Therapy reduced fear of spiders effectively. Performing rhythmic eye movements during exposure did not enhance therapy effects. Rhythmic eye movements during exposure resulted in lower heart rate than standard exposure.

EMDR as Treatment Option for Conditions Other Than PTSD: A Systematic Review

Eye Movement Desensitisation and Reprocessing (EMDR) is a treatment for post-traumatic stress disorder (PTSD). The technique is known to facilitate reprocessing of maladaptive memories that are thought to be central to this pathology. Here we investigate if EMDR therapy can be used in other conditions. We conducted a systematic literature search on PubMed, ScienceDirect, Scopus, and Web of Science. We searched for published empirical findings on EMDR, excluding those centred on trauma and PTSD, published up to 2020. The results were classified by psychiatric categories. Ninety articles met our research criteria. A positive effect was reported in numerous pathological situations, namely in addictions, somatoform disorders, sexual dysfunction, eating disorders, disorders of adult personality, mood disorders, reaction to severe stress, anxiety disorders, performance anxiety, Obsessive-Compulsive Disorder (OCD), pain, neurodegenerative disorders, mental disorders of childhood and adolescence, and sleep. Some studies reported that EMDR was successful in usually uncooperative (e.g., Dementia) or unproductive cases (e.g., aphasia). Moreover, in some severe medical conditions, when psychological distress was an obstacle, EMDR allowed the continuation of treatment-as-usual. Furthermore, the effects observed in non-pathological situations invite for translational research. Despite a generally positive outlook of EMDR as an alternative treatment option, more methodologically rigorous studies are needed. We discuss the advantages and limitations and possible implications for the hypothesised mechanisms of action.

Eye Movement Desensitization (EMD) to reduce posttraumatic stress disorder-related stress reactivity in Indonesia PTSD patients: a study protocol for a randomized controlled trial

Background

Posttraumatic stress disorder (PTSD) may develop after exposure to a traumatic event. Eye Movement Desensitization and Reprocessing (EMDR) is an evidence-based psychological treatment for PTSD. It is yet unclear whether eye movements also reduce stress reactivity in PTSD patients. This study aims to test whether eye movements, as provided during Eye Movement Desensitization (EMD), are more effective in reducing stress reactivity in PTSD patients as compared to a retrieval-only control condition.

Methods

The study includes participants who meet criteria of PTSD of the public psychological services in Jakarta and Bandung, Indonesia. One hundred and ten participants are randomly assigned to either an (1) Eye Movement Desensitization group (n = 55) or (2) retrieval-only control group (n = 55). Participants are assessed at baseline (T0), post-treatment (T1), 1 month (T2), and at 3 months follow-up (T3). Participants are exposed to a script-driven imagery procedure at T0 and T1. The primary outcome is heart rate variability (HRV) stress reactivity during script-driven imagery. Secondary outcomes include heart rate (HR), pre-ejection period (PEP), saliva cortisol levels, PTSD symptoms, neurocognitive functioning, symptoms of anxiety and depression, perceived stress level, and quality of life.

Discussion

If the EMD intervention is effective in reducing stress reactivity outcomes, this would give us more insight into the underlying mechanisms of EMDR’s effectiveness in PTSD symptom reduction.

Treating a 16 Year Old with a History of Severe Bullying: Supplementing Cognitive Behavioural Therapy with EMDR within the Context of a Case Formulation Approach

This article describes the use of a case formulation approach, integrating evidence-based treatment in the context of individual clinical traits. It focuses on the supplementation of cognitive behavioural therapy (CBT) with eye movement desensitization and reprocessing (EMDR) in the treatment of a young person, presenting with an initial diagnosis of obsessive-compulsive disorder (OCD). A case formulation suggested the possibility of a differential diagnosis of Adjustment Disorder, indicating the usefulness of the addition of EMDR sessions to process memories of severe bullying. Previous studies promote the idea of using EMDR in cases that do not meet the threshold for Post-Traumatic Stress Disorder (PTSD), in order to reduce the presentation of anxiety. Earlier research suggests that each of these models has specific strengths and attributes in the treatment of mental health difficulties and, whilst based within the context of a well-established case conceptualisation, can be effectively integrated.

How Does Eye Movement Desensitization and Reprocessing Therapy Work? A Systematic Review on Suggested Mechanisms of Action

Background: Eye movement desensitization and reprocessing [EMDR] is an innovative, evidence-based and effective psychotherapy for post-traumatic stress disorder [PTSD]. As with other psychotherapies, the effectiveness of EMDR contrasts with a limited knowledge of its underlying mechanism of action. In its relatively short life as a therapeutic option, EMDR has not been without controversy, in particular regarding the role of the bilateral stimulation as an active component of the therapy. The high prevalence of EMDR in clinical practice and the dramatic increase in EMDR research in recent years, with more than 26 randomized controlled trials published to date, highlight the need for a better understanding of its mechanism of action.

Methods: We conducted a thorough systematic search of studies published until January 2018, using PubMed, ScienceDirect, Web of Knowledge and Scopus databases that examined the mechanism of action of EMDR or provided conclusions within the framework of current theoretical models of EMDR functioning.

Results: Eighty-seven studies were selected for review and classified into three overarching models; (i) psychological models (ii) psychophysiological models and (iii) neurobiological models. The evidence available from each study was analyzed and discussed. Results demonstrated a reasonable empirical support for the working memory hypothesis and for the physiological changes associated with successful EMDR therapy. Recently, more sophisticated structural and functional neuroimaging studies using high resolution structural and temporal techniques are starting to provide preliminary evidence into the neuronal correlates before, during and after EMDR therapy.

Discussion: Despite the increasing number of studies that published in recent years, the research into the mechanisms underlying EMDR therapy is still in its infancy. Studies in well-defined clinical and non-clinical populations, larger sample sizes and tighter methodological control are further needed in order to establish firm conclusions.

The Effectiveness of Eye Movement Desensitization and Reprocessing Therapy to Treat Symptoms Following Trauma in Timor Leste

The effectiveness of eye movement desensitization and reprocessing (EMDR) therapy for treating trauma symptoms was examined in a postwar/conflict, developing nation, Timor Leste. Participants were 21 Timorese adults with symptoms of posttraumatic stress disorder (PTSD), assessed as those who scored ≥2 on the Harvard Trauma Questionnaire (HTQ). Participants were treated with EMDR therapy. Depression and anxiety symptoms were assessed using the Hopkins Symptom Checklist. Symptom changes post-EMDR treatment were compared to a stabilization control intervention period in which participants served as their own waitlist control. Sessions were 60-90 mins. The average number of sessions was 4.15 (SD = 2.06). Despite difficulties providing treatment cross-culturally (i.e., language barriers), EMDR therapy was followed by significant and large reductions in trauma symptoms (Cohen's d = 2.48), depression (d = 2.09), and anxiety (d = 1.77). At posttreatment, 20 (95.2%) participants scored below the HTQ PTSD cutoff of 2. Reliable reductions in trauma symptoms were reported by 18 participants (85.7%) posttreatment and 16 (76.2%) at 3-month follow-up. Symptoms did not improve during the control period. Findings support the use of EMDR therapy for treatment of adults with PTSD in a cross-cultural, postwar/conflict setting, and suggest that structured trauma treatments can be applied in Timor Leste.

Couple Therapy When One Spouse Has Cancer: Integration of EMDR and Relationship Enhancement Therapies

A diagnosis of cancer can be a major challenge for a couple. Some will navigate without major upheaval, but others will face difficulties that shake the foundations of the relationship. Eye movement desensitization and reprocessing (EMDR) therapy can be beneficial to both individuals in helping them resolve the present issues as well as past traumas that are hindering their ability to cope with the illness in the most effective way. This article describes how a couple therapy treatment developed by Johnson and Moore (2012, 2014) can be used for couples facing medical challenges. The treatment integrates individual EMDR therapy for each partner with conjoint couple therapy using Nonviolent Communication (Rosenberg, 2003) and Relationship Enhancement therapy (Guerney, 1987). The goals are to create a calming atmosphere between the couple, resolve the presenting problems, improve communication between the partners, and deepen the relationship. A descriptive case example describes the application of this treatment model to a couple who were struggling with the impact of the husband’s serious medical problems on the marriage. The article also provides direction for addressing various challenges in couple work.
