EMDR is now accepted as a treatment of choice by numerous mental health departments and trauma organizations.
EMDR has a broad base of published case reports and controlled research that supports it as an empirically validated treatment of trauma and other adverse life experiences. The Department of Defense/Department of Veterans Affairs Practice Guidelines have placed EMDR in the highest category, recommended for all trauma populations at all times. In addition, the International Society for Traumatic Stress Studies current treatment guidelines have designated EMDR as an effective treatment for PTSD (Foa, Keane, Friedman, & Cohen, 2009) as have the Departments of Health of both Northern Ireland and Israel (see below), which have indicated EMDR to be one of only two or three treatments of choice for trauma victims. The American Psychiatric Association Practice Guideline (2004) has stated that SSRI's, CBT, and EMDR are recommended as first-line treatments of trauma. Most recently, the World Health Organization (2013) has stated that trauma-focused CBT and EMDR are the only psychotherapies recommended for children, adolescents, and adults with PTSD. “Like CBT with a trauma focus, EMDR aims to reduce subjective distress and strengthen adaptive cognitions related to the traumatic event. Unlike CBT with a trauma focus, EMDR does not involve (a) detailed descriptions of the event, (b) direct challenging of beliefs, (c) extended exposure, or (d) homework.” (p.1)
See Shapiro (1999, 2001, 2002) for procedures, protocols, theories, and discussion of clinically valid research criteria. See Shapiro (2012) for a comprehensive narrative of cases, and in-session transcripts, and "EMDR for Trauma" in APA Psychotherapy Videotape series. More than twenty randomized studies support EMDR therapy as an effective and efficient treatment of trauma. More than two-dozen randomized studies and a recent meta-analysis (Lee & Cuijpers, 2013) have demonstrated the positive effects of the eye movement component.

EMDR was listed as an effective and empirically supported treatment for PTSD, and was given an AHCPR “A” rating for adult PTSD. This guideline specifically rejected the findings of the previous Institute of Medicine report, which stated that more research was needed to judge EMDR effective for adult PTSD. With regard to the application of EMDR to children, an AHCPR rating of Level B was assigned. Since the time of this publication, two additional randomized studies on EMDR have been completed (see below).

Trauma-focused CBT and EMDR are the only psychotherapies recommended for children, adolescents and adults with PTSD. "Like CBT with a trauma focus, EMDR therapy aims to reduce subjective distress and strengthen adaptive cognitions related to the traumatic event. Unlike CBT with a trauma focus, EMDR does not involve (a) detailed descriptions of the event, (b) direct challenging of beliefs, (c) extended exposure, or (d) homework." (p. 1)
EMDR has been compared to numerous exposure therapy protocols, with and without CT techniques. It should be noted that exposure therapy uses one to two hours of daily homework and EMDR uses none. The most recent meta-analyses are listed here.

Twelve sessions of EMDR eliminated post-traumatic stress disorder in 77.7% of the multiply traumatized combat veterans studied. There was 100% retention in the EMDR condition. Effects were maintained at follow-up. This is the only randomized study to provide a full course of treatment with combat veterans. Other studies (e.g., Boudewyns/Devilly/Jensen/Pitman et al./Macklin et al.) evaluated treatment of only one or two memories, which, according to the International Society for Traumatic Stress Studies Practice Guidelines (2000), is inappropriate for multiple-trauma survivors. The VA/DoD Practice Guideline (2004) also indicates these studies (often with only two sessions) offered insufficient treatment doses for veterans.

Both EMDR and prolonged exposure produced a significant reduction in PTSD and depression symptoms. This is the only research comparing EMDR and exposure therapy that equalized homework. The study found that 70% of EMDR participants achieved a good outcome in three active treatment sessions, compared to 29% of persons in the prolonged exposure condition. EMDR also had fewer dropouts.

Both EMDR and stress inoculation therapy plus prolonged exposure (SITPE) produced significant improvement, with EMDR achieving greater improvement on PTSD intrusive symptoms. Participants in the EMDR condition showed greater gains at three-month follow-up. EMDR required three hours of homework compared to 28 hours for SITPE.

Both EMDR and exposure therapy plus cognitive restructuring (with daily homework) produced significant improvement. EMDR was more beneficial for depression, and social functioning, and required fewer treatment sessions. Subsequent reevaluation of the data indicated that “For pre- to post-treatment IES mean change score, EMDR patients also appeared to have had better treatment outcome than E+CR patients” and EMDR therapy was a predictor of positive outcome: Karatzias, A., Power, K.

The only randomized study to show exposure statistically superior to EMDR on two subscales (out of 10). This study used therapist assisted “in vivo” exposure, where the therapist takes the person to previously avoided areas, in addition to imaginal exposure and one hour of daily homework (@ 50 hours). The EMDR group used only standard sessions and no homework.

All treatments led to significant decreases in PTSD symptoms for subjects in the treatment groups as compared to those on a waiting list, with a greater reduction in the EMDR group, particularly with respect to intrusive symptoms. In the 2-3 weeks of the study, 40-60 additional minutes of daily homework were part of the treatment in the other two conditions.

60 railroad employees who had experienced fatal grade crossing accidents were evaluated for workshop outcomes, and for the additive effects of EMDR treatment. Although the workshop was successful, in this setting, the addition of a short session of EMDR (5-40 minutes) led to significantly lower, sub clinical, scores which further decreased at follow up.
Sprang, G. (2001). The use of eye movement desensitization and reprocessing (EMDR) in the treatment of traumatic stress and complicated mourning: Psychological and behavioral outcomes. Research on Social Work Practice, 11, 300-320.
In a multi-site study, EMDR significantly reduced symptoms more often than the CBT treatment on behavioral measures, and on four of five psychosocial measures. EMDR was more efficient, inducing change at an earlier stage and requiring fewer sessions. Positive recall of the deceased was significantly greater post treatment in the EMDR condition.

Results indicate that the EMDR approach can be effective in a group setting, and in an acute situation, both in reducing symptoms of posttraumatic and peritraumatic stress and in “inoculation” or building resilience in a setting of ongoing conflict and trauma.
Adaptive Information Processing and EMDR Procedures
The Adaptive Information Processing model (Shapiro, 2001, 2002, 2007) is used to explain EMDR's clinical effects and guide clinical practice. This model is not linked to any specific neurobiological mechanism since the field of neurobiology is as yet unable to determine this in any form of psychotherapy (nor of most medications). This section includes literature to provide an overview of the model and procedures, as well as selected research and case reports that demonstrate the predictive value of the model in the treatment of life experiences that appear to underlie a variety of clinical complaints.

The study evaluated the impact of EMDR treatment on bias mechanisms in depressed subjects in regard to negative emotional valence evaluation. “The results indicated that it generated important cognitive emotional changes in such mechanisms.” Priming tests indicated changes in the negative valence evaluation of emotional information indicative of recovery with decreased reaction times in the neutral and positive stimuli processing.”

“Five consecutive cases of phantom limb pain were treated with EMDR. Four of the five clients completed the prescribed treatment and reported that pain was completely eliminated, or reduced to a negligible level. . . The standard EMDR treatment protocol was used to target the accident that caused the amputation, and other related events.”
Mechanism of Action
EMDR contains many procedures and elements that contribute to treatment effects. While the methodology used in EMDR has been extensively validated (see above), questions still remain regarding mechanism of action. However, since EMDR achieves clinical effects without the need for homework, or the prolonged focus used in exposure therapies, attention has been paid to the possible neurobiological processes that might be evoked. Although the eye movements (and other dual attention stimulation) comprise one only one procedural element, this element has come under greatest scrutiny.Randomized controlled studies evaluating mechanism of action of the eye movement component follow this section.

Changes in heart rate, skin conductance and LF/HF-ratio, finger temperature, breathing frequency, carbon dioxide and oxygen levels were documented during the eye movement condition. It was concluded the “eye movements during EMDR activate cholinergic and inhibit sympathetic systems. The reactivity has similarities with the pattern during REM sleep.”
Lee, C.W., Taylor, G., & Drummond, P.D. (2006) The active ingredient in EMDR: Is it traditional exposure or dual focus of attention? Clinical Psychology and Psychotherapy, 13, 97-107
This study tested whether the content of participants’ responses during EMDR is similar to that thought to be effective for traditional exposure treatments (reliving), or is more consistent with distancing which would be expected given Shapiro’s proposal of dual focus of attention. Greatest improvement on a measure of PTSD symptoms occurred when the participant processed the trauma in a more detached manner, which indicates the underlying mechanisms of EMDR and exposure therapy are different.

“Specifically, the EM manipulation used in the present study, reported previously to facilitate episodic memory, resulted in decreased interhemispheric EEG coherence in anterior prefrontal cortex. Because the gamma band includes the 40 Hz wave that may indicate the active binding of information during the consolidation of long-term memory storage (e.g., Cahn and Polich, 2006), it is particularly notable that the changes in coherence we found are in this band. With regard to PTSD symptoms, it may be that by changing interhemispheric coherence in frontal areas, the EMs used in EMDR foster consolidation of traumatic memories, thereby decreasing the memory intrusions found in this disorder.”

The article explores the differences between memory reconsolidation and extinction. This new area of investigation is worthy of additional attention. Reconsolidation may prove to be the underlying mechanism of EMDR, as opposed to extinction caused by prolonged exposure therapies. “Memory reconsolidation after retrieval may be used to update or integrate new information into long-term memories . . . Brief exposure … seems to trigger a second wave of memory consolidation (reconsolidation), whereas prolonged exposure . . leads to the formation of a new memory that competes with the original memory (extinction).”

Study involving biofeedback equipment has supported the hypothesis that the parasympathetic system is activated by finding that eye movements appeared to cause a compelled relaxation response. More rigorous research with trauma populations is needed.
Randomized Studies of Hypotheses Regarding Eye Movements
A number of International Practice Guideline committees have reported that the clinical component analyses reviewed by Davidson & Parker (2001) are not well designed (International Society for Traumatic Stress Studies/ISTSS (2000); DoD/DVA). Davidson & Parker note that there is a trend toward significance for eye movements when the studies conducted with clinical populations are examined separately. Unfortunately even these studies are methodologically flawed. As noted in the ISTSS guidelines (Chemtob et al., 2000), since these clinical populations received insufficient treatment doses to obtain substantial main effects, they are inappropriate for component analyses. However, as noted in the DoD/DVA (2004) guidelines, numerous memory researchers have evaluated the eye movements used in EMDR. These studies have found a direct effect on emotional arousal, imagery vividness, attentional flexibility, and memory association. In addition, a new study has examined the hypothesis that the eye movements cause a “distancing effect” (Lee & Drummond, 2008) and is listed below as well.

Combat Veteran Treatment
As noted in the American Psychiatric Association Practice Guidelines (2004, p.18), in EMDR “traumatic material need not be verbalized; instead, patients are directed to think about their traumatic experiences without having to discuss them.” Given the reluctance of many combat veterans to divulge the details of their experience, this factor is relevant to willingness to initiate treatment, retention and therapeutic gains. It may be one of the factors responsible for the lower remission and higher dropout rate noted in this population when CBT techniques are used.
As described previously, Carlson et al. (1998) reported that after twelve treatment sessions, 77.7% of the combat veterans no longer met criteria for PTSD. There were no dropouts and effects were maintained at 3- and 9-month follow-up. In addition, the Silver et al., (1995) analysis of an inpatient veterans’ PTSD program (n = 100) found EMDR to be superior to biofeedback and relaxation training on seven of eight measures. All other randomized studies of veterans have used insufficient treatment doses to assess PTSD outcomes (e.g., two sessions; see ISTSS, 2000; DVA/DoD, 2005). Sufficient treatment time must be used for multiply traumatized veterans (e.g., see below: Russell et al., 2007). However, in a process analysis, Rogers et al. (1999) compared one session of EMDR and exposure therapy with inpatient veterans, and a different recovery pattern was observed. The EMDR group demonstrated a more rapid decline in self-reported distress (e.g., SUD levels decreased with EMDR and increased with exposure).
As stated in the American Psychiatric Practice Guidelines (2004, p. 36), if viewed as an exposure therapy, “EMDR employs techniques that may give the patient more control over the exposure experience (since EMDR is less reliant on a verbal account) and provides techniques to regulate anxiety in the apprehensive circumstance of exposure treatment. Consequently, it may prove advantageous for patients who cannot tolerate prolonged exposure as well as for patients who have difficulty verbalizing their traumatic experiences. Comparisons of EMDR with other treatments in larger samples are needed to clarify such differences.”
Such research is highly recommended. In addition, since EMDR utilizes no homework to achieve its effects it may be particularly suited for front line alleviation of symptoms (see Russell, 2006; Wesson & Gould, 2009). Further, the prevalent somatic and chronic pain problems experienced by combat veterans indicate the need for additional research based upon the reports of Russell (2008), Schneider et al., (2007, 2008) and Wilensky (2007), which demonstrate EMDR’s capacity to successfully treat phantom limb pain (see also Ray & Zbik, 2001). The ability of EMDR to simultaneously address PTSD, depression, and pain can have distinct benefits for DVA/DoD treatment.
