The Role of Eye Movement Desensitization and Reprocessing (EMDR) Therapy in Medicine: Addressing the Psychological and Physical Symptoms Stemming from Adverse Life Experiences. Addressing the Psychological and Physical Symptoms Stemming from Adverse Life Experiences. Permanente Journal, 2014 Winter;18(1):71-77:
A substantial body of research shows that adverse life experiences contribute to both psychological and biomedical pathology. Eye movement desensitization and reprocessing (EMDR) therapy is an empirically validated treatment for trauma, including such negative life experiences as commonly present in medical practice. The positive therapeutic outcomes rapidly achieved without homework or detailed description of the disturbing event offer the medical community an efficient treatment approach with a wide range of applications.

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.
