1. Aetna considers eye movement desensitization and reprocessing (EMDR) therapy medically necessary for the treatment of post-traumatic stress disorder (PTSD).

    

2. Aetna considers EMDR therapy experimental and investigational for all other indications (including those listed below) because its effectiveness for indications other than PTSD has not been established:

Eye movement desensitization and reprocessing (EMDR) therapy is a complex method of psychotherapy that combines a range of therapeutic approaches with eye movements or other forms of rhythmical stimulation (e.g., sound and touch) in ways that stimulate the brain's information processing system.  Eye movement desensitization and reprocessing was introduced in 1989 as a treatment for post-traumatic stress disorder (PTSD).  Since then, it has been proposed as a treatment of various psychiatric and behavioral disorders including phobias, panic and anxiety disorders, as well as eating disorders.

Guidelines on PTSD from the National Institute for Clinical Excellence (NICE, 2005) state that all people with PTSD should be offered a course of trauma-focused psychological treatment (trauma-focused cognitive behavioral therapy (CBT) or EMDR).  National Institute for Clinical Excellence guidelines note that these treatments should normally be provided on an individual outpatient basis.

Guidelines on PTSD from the American Psychiatric Association (APA, 2004) stated that CBT and EMDR have been shown to be effective for core symptoms of acute and chronic PTSD.  These guidelines note, however, that no controlled studies of EMDR have been conducted that would establish data-based evidence of its efficacy as an early preventive intervention for PTSD.  The APA guidelines state that stress inoculation, imagery rehearsal, and prolonged exposure techniques may also be indicated for treatment of PTSD and PTSD-associated symptoms such as anxiety and avoidance.  The APA guidelines observe that the shared element of controlled exposure of some kind may be the critical intervention.

In reviewing the evidence supporting EMDR, the APA found that, like many of the studies of other cognitive behavior and exposure therapies, most of the well-designed EMDR studies have been small, but several meta-analyses have demonstrated efficacy similar to that of other forms of cognitive and behavior therapy.  The AAP noted that studies also suggest that the “eye movements are neither necessary nor sufficient to the outcome, but these findings remain controversial.”  “Although it appears that efficacy may be related to the components of the technique common to other exposure- based cognitive therapies, as in the previously described cognitive behavior therapies, further study is necessary to clearly identify the effective subcomponents of combined techniques.  Follow-up studies are also needed to determine whether observed improvements are maintained over time” (APA, 2004).

Advocates of EMDR therapy state that it is a specialized approach and method that requires supervised training for full therapeutic effectiveness and client safety.  Training is considered mandatory for appropriate use.  However, a meta-analysis of the literature on EMDR by Davidson and Parker (2001) found that the effectiveness of EMDR was not affected by whether the therapist providing the treatment was trained by the EMDR Institute.

There are insufficient data to support the use of EMDR in the treatment of other psychiatric and behavioral disorders including anger, guilt, phobias, dissociative disorders, eating disorders, and panic and anxiety disorders other than PTSD.  In a randomized study on the effectiveness of EMDR treatment on negative body image in eating disorder inpatients, Bloomgarden and Calogero (2008) conclued that further research is needed to determine whether or not EMDR is effective for treating the variety of eating pathology presented by eating disorder inpatients.

In a case series, Schneider et al (2008) assessed EMDR therapy for patients with chronic phantom limb pain (PLP).  A total of 5 subjects with PLP ranging from 1 to 16 years were included in this study.  All patients were on extensive medication regimens prior to EMDR therapy; 3 to 15 sessions of EMDR were used to treat the pain and the psychological ramifications.  Patients were measured for continued use of medications, pain intensity/frequency, psychological trauma, and depression.  Treatment with EMDR resulted in a significant decrease or elimination of PLP, reduction in depression and PTSD symptoms to sub-clinical levels, and significant reduction or elimination of medications related to the PLP and nociceptive pain at long-term follow-up.  The authors concluded that the overview and long-term follow-up indicate that EMDR therapy was successful in the treatment of both PLP and the psychological consequences of amputation.  The latter include issues of personal loss, grief, self-image, and social adjustment.  These results suggest that (i) a significant aspect of PLP is the physiological memory storage of the nociceptive pain sensations experienced at the time of the event, and (ii) these memories can be successfully reprocessed.  They stated that further research is needed to explore the theoretical and treatment implications of this information-processing approach.

de Roos et al (2010) examined if a psychological treatment directed at processing the emotional and somatosensory memories associated with amputation reduces PLP.  A total of 10 consecutive participants (6 men and 4 women) with chronic PLP after leg amputation were treated with EMDR.  Pain intensity was assessed during a 2-week period before and after treatment (mean number of sessions = 5.9), and at short-term (3 months) and long-term (mean of 2.8 years) follow-up.  Multi-variate ANOVA for repeated measures revealed an overall time effect (F[2, 8] = 6.7; p < 0.02) for pain intensity.  Pair-wise comparison showed a significant decrease in mean pain score before and after treatment (p = 0.00), which was maintained 3 months later.  All but 2 subjects improved and 4 were considered to be completely pain-free at 3 months follow-up.  Of the 6 subjects available at long-term follow-up (mean of 2.8 years), 3 were pain-free and 2 had reduced pain intensity.  The authors concluded that these preliminary results suggested that, following a psychological intervention focused on trauma or pain-related memories, substantial long-term reduction of chronic PLP can be achieved.  However, they stated that larger outcome studies are needed.

In a pilot study, Sandstrom and colleagues (2008) examined the effects of EMDR in women with post-traumatic stress after childbirth.  This study consisted of a "before and after" treatment design combined with follow-up measurements 1 to 3 years after EMDR treatment.  Quantitative data from questionnaires (Traumatic Event Scale [TES]) were collected.  In addition, qualitative data from individual interviews with the participants were collected as well as data from the psychotherapist's treatment notes of the EMDR treatment sessions.  A total of 4 women with post-traumatic stress following childbirth (1 pregnant and 3 non-pregnant) were included in this study.  All participants reported reduction of post-traumatic stress after treatment.  After 1 to 3 years, the beneficial effects of EMDR treatment remained for 3 of the 4 women.  Symptoms of intrusive thoughts and avoidance seemed most sensitive for treatment.  The authors concluded that EMDR might be a useful tool in the treatment of non-pregnant women severely traumatized by childbirth; however, they stated that further research is needed.

Bae et al (2008) stated that while CBT is considered to be the first-line therapy for adolescent depression, there are limited data on whether other psychotherapeutic techniques are also effective in treating adolescents with depression.  This report suggested the potential application of EMDR for treatment of depressive disorder related, not to trauma, but to stressful life events.  At present, EMDR has only been empirically validated for only trauma-related disorders such as PTSD.  These researchers reported the findings of 2 teenagers with major depressive disorder (MDD) who underwent 3 and 7 sessions of EMDR aimed at memories of stressful life events.  After treatment, their depressive symptoms decreased to the level of full remission, and the therapeutic gains were maintained after 2 and 3 months of follow-up.  The effectiveness of EMDR for depression is explained by the model of adaptive information processing.  Given the powerful effects observed within a brief period of time, the authors suggested that further investigation of EMDR for depressive disorders is warranted.

Torun (2010) noted that vaginismus is a type of sexual dysfunction in which spasm of the vaginal musculature prevents penetrative intercourse.  The main diagnostic criterion is the presence of recurrent or persistent involuntary spasm of the musculature of the outer third of the vagina that interferes with sexual intercourse.  In many cases, associated pain or the fear of pain may contribute to its persistence.  These researchers reported 2 patients who presented with vaginismus that developed secondary to childhood sexual trauma, which was treated with the EMDR.  Randomized controlled trials with PTSD patients and with victims of sexual abuse have shown that EMDR is effective.  The standard 8-phase EMDR protocol was used in both of the presented cases.  Following 3 sessions of EMDR, the patients exhibited a substantial reduction in self-reported and clinician-rated anxiety, and a reduction in the credibility of dysfunctional beliefs concerning sexual intercourse.  The authors concluded that these findings support the notion that EMDR could be an effective treatment alternative for patients with vaginismus of traumatic etiology.  Thes preliminary results need to be validated with well-designed studies.
