PTSD and Complementary Alternative Medicine - Research Opportunities
VA Office of Research and Development
Complementary and Alternative Medicine treatment for Post-Traumatic Stress Disorder (PTSD) was the subject of the meeting held May 17, 2011 in Washington DC. Participants who attended included representatives of the Department of Defense, Department of Veterans Affairs, and the Department of Health and Human Services (National Institutes of Health, National Center for Complimentary and Alternative Medicine).
An evidence review identified that the highest quality evidence exists for acupuncture. However, strong conclusions cannot reliably be drawn on the basis of a single Randomized Control Trial (RCT). The greatest breadth of evidence exists for relaxation interventions-three RCTs were identified that examined forms of breathing and muscle relaxation. In each case, the trials were preliminary and design flaws limited interpretation of study findings, which were positive overall. Further conclusions cannot be made in the absence of well-designed investigations of these modalities.
The evidence base for meditation therapies is similarly limited by a paucity of well-designed trials, although early evidence is promising. In addition to a lack of scientific rigor and the need to replicate preliminary findings, the current literature is limited to concentrative meditative techniques. No RCTs of other common mind-body interventions, including mindfulness meditation and yoga, were identified in our review of the published, peer-reviewed literature. For manipulative and body-based CAM therapies, the evidence base is extremely limited, and for movement-based and energy therapies, we identified no RCTs, published or in progress. Based on the discussion at the meeting an addendum to the report will examine CAM treatments in depression and anxiety disorder.
In a survey presented at the meeting concerning CAM practice in the Department of Veterans Affairs, in 2011, 89% of VA facilities offer CAM therapies compared to 84% in 2002. Of facilities offering CAM, more directly provide CAM therapies compared to a 2002 (65% versus 45%). The five most common CAM provided are Meditation (72% of VA hospitals); Stress Management / Relaxation Therapy (66%); Guided Imagery (58%) Progressive Muscle Relaxation (53%); and Biofeedback (50%).
Participants identified that efforts should be undertaken to improve documentation of CAM in the VA electronic health record. A Veterans Affairs CAM working group is developing clinical directives related to the use of CAM therapies within the VA. The workgroup will also recommend standards for credentialing and privileging CAM providers within VA.
Study design issues for PTSD and CAM include: defining fidelity, clarification therapeutic dose, defining controls/placebos, and qualitative / quantitative data collection strategies. Participants recommended that the study of the underlying mechanism should be included in studies. Examples of mechanism measures include - control of attention, relaxation response, norepinephrine, epinephrine, cytokines, neuropeptides, cortisols, hyperarousal, heart rate variability, and advanced imaging such as Positron Emission Tomography, functional Magnetic Resonance Imaging and Magnetoencephalography. CAM approaches may need to be modified to ensure appropriateness for the PTSD patient population. Sleep is an important issue for PTSD and outcome measures should include this domain. Similarly, there may be promise in evaluating outcome measures which focus on pain, treatment adherence, anxiety, adjustment issues, adverse effects, family and social functioning, depression and other co-morbidities.
The VA Office of Research and Development (ORD) is in the process of reviewing applications for the recent Request for Application (RFA) focused on meditative based treatments for PTSD. Depending on scientific review and available funding it is anticipated that up to 3 projects will be supported and will begin in the fall of 2011. ORD will discuss the results of this meeting with VA research offices and post a meeting summary on the ORD internet page. The VA Office of Research and Development has a continuing interest in this topic and encourages investigators to apply for support through merit review mechanisms.
The VA Office of Mental Health is pursuing development of clinical demonstration projects which would examine current treatment and practice of meditation for PTSD at 4 to 8 sites. Meeting participants noted that it is important for the demonstration projects to examine how changes in provider type, setting, and context impact patient CAM outcomes, and potential adverse events associated with CAM treatments.
Meeting participants identified the following issues for consideration. 1) developing CAM manuals and moving treatment approaches towards standardized versions of CAM; 2) using common measures across sites; 3) exploring provider acceptability of CAM treatment in this population; and 4) developing plans if there are a lack of qualified instructors for CAM.
In 2007, a national survey identified that 38.3% of adults use Complementary and Alternative Medicine (CAM). CAM use is greater in women and those with higher education and income. The most CAM use reported was of natural products (17.7%) followed by deep breathing (12.7%) and meditation (9.4%). A recent publication examined CAM use in active duty military personnel who participated in the millennium cohort study. Over a 12 month period, 39% indicated that they used at least one CAM treatment. Individuals reporting one or more health conditions were more likely to use CAM.
CAM is coming into the mainstream of healthcare, with rapid growth in utilization over the last several years. CAM use in Post-Traumatic Stress Disorder (PTSD) was the subject of the meeting held May 17, 2011 in Washington DC. Participants who attended included representatives of the Department of Defense, Department of Veterans Affairs (VA), and the Department of Health and Human Services (National Institutes of Health, National Center for Complimentary and Alternative Medicine).
Remarks of VA Deputy Secretary W. Scott Gould
In his opening remarks, the VA Deputy Secretary emphasized that the VA has begun the following activities:
- First, conducting a comprehensive literature review of all types of meditation;
- Second, develop a classification scheme for the various types of meditative techniques;
- Third, constructing a research effort that includes meditation and, based on the literature review, supporting the development of new research appropriate to the level of scientific/clinical evidence that can be marshaled at this time.
Fourth, adopting evidence based methods to evaluate results consistently across studies.
The Deputy Secretary emphasized that collaborating with one another will help us advance this research more quickly and more effectively. The Deputy Secretary emphasized that one particular treatment to evaluate is meditation. Meditative techniques should be culturally sensitive, easily learned, and translate across different veteran populations. The VA and DoD have dedicated funds for this research; additional funding sources are also sought.
PTSD and CAM evidence review
The evidence review sought to address the following questions:
- In adults with PTSD, are mind-body CAM therapies (e.g., acupuncture, yoga, meditation) more efficacious than control for PTSD symptoms and health-related quality of life?
- In adults with PTSD, are manipulative and body-based CAM therapies (e.g., spinal manipulation, massage) more efficacious than control for PTSD symptoms and health-related quality of life?
- In adults with PTSD, are CAM therapies that are movement-based or involve energy therapies more efficacious than control for PTSD symptoms and health-related quality of life?
- For treatments evaluated in Key Questions 1-3 that lack randomized controlled trials, is there evidence from other study designs that suggests the potential for treatment efficacy?
- Randomized Controlled Trials (RCTs) for Key Questions (KQs) 1-3
- Prospective, comparative and non comparative studies for KQ 4
- Population: Adults > 18 yrs who met diagnostic criteria for PTSD, validated severity measures, or clinical diagnosis; in acute-phase treatment
- Interventions: Mind-body, manipulative or body-based, movement-based, or energy therapies
- Comparators: Any control condition (including no treatment) or active therapy (e.g., evidence-based, cognitive-behavioral therapies for PTSD)
- Outcomes: PTSD diagnosis and symptom severity, health-related quality of life, functional status, patient satisfaction, and treatment adherence, reported ? 6 weeks post intervention
- Setting: Community, outpatient mental health or general medical.
- Non-English language publication
- Studies not conducted in Westernized countries
- Patient populations with psychosis, acute suicidality, or substance abuse
- Studies that included a CAM therapy in both intervention and control arms
- Interventions commonly considered standard therapy (e.g., biofeedback, or relaxation skills training as part of CBT)
- PTSD as a comorbid rather than primary diagnosis
- Intervention used in a continuation or maintenance phase of treatment
- Relaxation: excluded if the control and/or description of intervention/CAM components unclear (e.g., "3 relaxation skills taught")
Additionally, an assessment of risk of bias: applied quality criteria described in Agency for Healthcare and Research Quality (AHRQ) Methods Guide for Effectiveness and Comparative Effectiveness Reviews was conducted.

Considered in sum, the highest quality evidence exists for acupuncture. However, strong conclusions cannot reliably be drawn on the basis of a single RCT; replication of findings is required. The greatest breadth of evidence exists for relaxation interventions-three RCTs were identified that examined forms of breathing and muscle relaxation. In each case, the trials were preliminary and design flaws limited interpretation of study findings, which were positive overall. Further conclusions cannot be made in the absence of well-designed investigations of these modalities.
The evidence base for meditation therapies is similarly limited by a paucity of well-designed trials, although early evidence is promising. In addition to a lack of scientific rigor and the need to replicate preliminary findings, the current literature is limited to concentrative meditative techniques. No RCTs of other common mind-body interventions, including mindfulness meditation and yoga, were identified in our review of the published, peer-reviewed literature. However, 17 ongoing and/or unpublished studies registered with ClinicalTrials.gov, suggesting that this is a burgeoning area of research. Approximately half of these trials are ongoing, and the majority are recruiting active military and/or Veteran samples. Thus, a significantly larger, broader, and stronger evidence base can be anticipated within the next several years.
For manipulative and body-based CAM therapies, the evidence base is extremely limited, and for movement-based and energy therapies, we identified no RCTs, published or in progress. Research on CAM therapies for PTSD appears to be on the rise, as suggested by the 17 pertinent RCTs identified in ClinicalTrials.gov.
Table 1: Evidence Summary
Evidence review discussion
The term CAM was used in the discussion to refer to a category of therapies - mind-body medicine (e.g., meditation, yoga, and acupuncture), manipulative, and body-based practices (e.g., spinal manipulation, massage therapy). Meeting participants at times did not identify the particular CAM therapy that was the focus of their comments. Another issue relates to the definition of CAM, some regard biofeedback, progressive muscle relaxation, or other treatments as CAM, while others consider these techniques to be standard treatment. Regarding classification of PTSD, current thinking is that PTSD is a disorder of physical and emotional dysregulation rather than as an anxiety disorder.
Comments raised by meeting participants:
Since many veterans with PTSD also suffer from co-morbid anxiety and depressive disorders, what does the CAM research show in these conditions that might relate to the outcomes in PTSD? There is also overlap with pain and PTSD. Does the exclusion of substance use disorders limit the evidence base?
Response - The eligibility criteria were inclusive - all adults, treated in primary care, mental health care or the community, with PTSD - diagnosed clinically or by exceeding a threshold on a symptom scale. Related illnesses (e.g. major depressive disorder or other anxiety disorders) were not included and we recognize and acknowledge this as a limitation in the discussion. Given the short timeline for this project, a review of CAM for related conditions was not feasible. However, related conditions will be addressed in a supplement to this report.
Consistent with the AHRQ EPC methods manual, we give reasons for exclusion on articles undergoing full text review. However, we had a porous filter at the citation screening phase (using 2 reviewers) and are confident that we did not exclude potentially relevant studies. We also completed a quality check on a substantial subset of the citation screening decisions and verified accurate exclusions. We updated the report to reflect this validation process.
- Why were maintenance phase treatments excluded?
Response - Maintenance phase treatment addresses a different question. That is, once a patient remits from PTSD, does continued treatment decrease risk of relapse? Studies addressing maintenance phase treatments are typically studied through randomized discontinuation trials. The clinical issue and type of studies are sufficiently different, that it should be evaluated as a separate question. That said, we did not exclude any studies at the FTR stage due to maintenance phase treatment and our collective recall is none of these studies were excluded at the citation screening phase.
Could we learn more from the existing evidence - particularly relaxation literature?
Response - Relaxation therapy was not excluded. However, relaxation therapy is frequently used as a placebo control in trials of therapy (such as CPT or Prolonged exposure). In these trials, relaxation therapy was typically not described in sufficient detail to understand the components and in the instances when it was described, it did not meet the definition of an adequate test of relaxation therapy. Therefore, these studies were excluded. To include studies where relaxation is not described and conceptualized as a control intervention would almost certainly be an unfair evaluation of relaxation. To draw a parallel to medication studies, including relaxation studies that did not describe the relaxation intervention would be equivalent to evaluating studies of a pill with unknown contents.
We included studies of relaxation vs. control or vs. an empirically supported active therapy (e.g. Cognitive Processing Therapy, Prolonged Exposure Therapy). We did not include studies of relaxation for other disorders (e.g. Major Depressive Disorder). Studies evaluating relaxation for closely related conditions have the potential to yield useful, but indirect evidence about relaxation therapies efficacy for PTSD. However, these studies were outside the scope of the current review.
A recent review focused on meditation practices and health supported by the Agency for Healthcare Research and Quality identified six studies evaluating relaxation response and several outcome measures (muscle tension, heart rate, and blood pressure) in healthy populations. The combined results of two studies showed a small non-significant change in muscle tension favoring relaxation response compared to biofeedback. The combined results of three trials showed a significant reduction in heart rate favoring rest compared to relaxation response. The combined results of two studies indicated a small, non-significant reduction in blood pressure favoring relaxation response compared to rest.
- What about chronic versus acute patients?
Response - There were too few studies to make any comparisons of chronic versus acute PTSD
- What about non randomized studies - observational / qualitative, pre-post, other clinical populations (e.g. anxiety and depression)?
Response - Our study included non-randomized comparative studies evaluating eligible CAM treatments for PTSD. However, there were few of these studies. The review group identified a small number of non-comparative, non-RCT studies for PTSD that were not included in the report. These non-comparative studies give extremely limited information about treatment effects and were excluded. However, in response to feedback that even this limited information could be informative; the group will briefly summarize these non-comparative studies in key question four.
It was suggested that the topic area of meditation include strategies that build off meditative techniques such as yoga, and other movement based forms of meditation. Lessons also might be learned from the incorporation of mindfulness in cognitive behavioral therapy. Another potential question for a different literature review might be to consider which CAM treatments may be the most likely candidates for greatest potential benefit based on how well the theoretical mechanisms of action match the key features of PTSD that would be targets for improvement (i.e. hyperarousal, numbing, avoidance and re-experiencing). For example, mindfulness meditation could be a candidate due to the findings that mindfulness meditation reduces hyperarousal and promotes openness to versus avoidance of experience, e.g. distressing images, memories, emotions.
Recommendations / Next Steps
The team that developed the evidence review will also perform a search for systematic reviews that evaluate eligible CAM treatments for related mental health disorders such as depression and anxiety disorder. The team will use a formal process to identify eligible reviews, and apply criteria to rate the quality of eligible reviews. In the report they will summarize and critically discuss each fair or good quality systematic review. Included reviews will be limited to those published within the past 5 years. A separate summary will be developed as a supplement to the current report.
Health Care Analysis and Information Group (HAIG) Survey 2011
In 2011, 89% of VA facilities offer CAM therapies compared to 84% in 2002. Of facilities offering CAM, more directly provide CAM therapies compared to a 2002 (65% versus 45%). The five most common CAM provided are Meditation (72% of VA hospitals); Stress Management / Relaxation Therapy (66%); Guided Imagery (58%) Progressive Muscle Relaxation (53%); and Biofeedback (50%);. If facilities offer CAM, they are providing more types of CAM therapy compared to 2002. The most common reasons for providing CAM therapy are for wellness promotion and patient preference. The most common reasons for not providing CAM are lack of providers, perceived lack of patient interest, and perceived lack of evidence for efficacy.
Of the facilities that offer meditation, 79% offer mindfulness meditation, 13% offer mantra repetition meditation, and 8% offer Transcendental Meditation. The top five most common conditions associated with CAM treatment are stress management, anxiety, PTSD, depression, and back pain. The greatest use of CAM therapies is in the mental health field. A variety of VA providers offer CAM therapies - psychologists, physicians, recreational therapist, nurses, physical therapists, occupational therapists, social workers, and others. The survey indicated that documentation of CAM therapies in the medical record is poor. Additionally CPT and HCPCS codes are usually not used. The survey indicated that the belief by health care providers in the scientific evidence of the effectiveness of CAM therapies appears greater than the actual documented evidence of effectiveness.
There is a wide array of clinical practice approaches to CAM. CAM modalities can help connect patients with mental health services and provides an entry way to other evidenced-based treatment modalities as needed.
- Efforts should be undertaken to improve documentation practices in CPRS.
- Educational material should be developed for patients and health care providers.
- A considerable amount of CAM is used but it is not well documented. Better application of CPT codes would allow more accurate reporting and investigation of CAM.
- Credentialing issues arise when attempting to hire a CAM provider, resulting in CAM mostly being offered by standard providers. CAM providers can't be hired in the VA as there is no occupation code. In addition, many CAM providers are not licensed. Acupuncturists are a notable exception. Legislative approval/support would be needed to establish occupational codes for CAM providers. Many of the relevant CAM fields do not have a certifying body.
- Within VA, there is not much local knowledge across service lines about what CAM treatments are being offered. VA facilities are providing CAM, more often for general wellness versus mental health conditions such as PTSD. There is a need to distinguish CAM as used for treatment versus wellness and self-administered or offered by a practitioner.
Recommendations / Next Steps
Efforts should be undertaken to improve documentation of CAM in the VA. A CAM working group led by Dr. Ezeji-Okoye is working on clinical directives related to the use of CAM therapies within the VA. The workgroup will also recommend standards for credentialing and privileging CAM providers within VA.
Research Opportunities and Design Issues
CAM therapies are likely to have modest treatment effect sizes. Additionally, providing CAM as an adjunctive treatment can make sample sizes needed to conduct the study a challenge. Selection of appropriate outcome measures is also important. It should not be lost that CAM treatments are desired by patients, so quality of life, perceived health status, and satisfaction should be considered.
Meditation at its basic level is learning to train attention. This is also a central ingredient in many other CAM techniques (tai chi, yoga, etc.). How does learning to focus attention or training attention affect/help existing strategies for managing PTSD?
Design issues include: defining fidelity, clarification therapeutic dose, defining controls/placebos, and qualitative / quantitative data collection strategies. Touch based / movement therapies should also be investigated, but may not be appropriate for every veteran patient suffering from PTSD. The study of the underlying mechanism should be included in studies, but may conflict with perceptions regarding the holistic philosophy of CAM. Examples of mechanism measures include - control of attention, relaxation response, norepinephrine, epinephrine, cytokines, neuropeptides, cortisols, hyperarousal, heart rate variability, and advanced imaging such as Positron Emission Tomography, functional Magnetic Resonance Imaging and Magnetoencephalography.
CAM approaches may need to be modified to ensure appropriateness for the PTSD patient population. Difficulties in learning meditation due to hyper arousal may require adapting meditative techniques for this population and individualizing techniques when necessary. Potential for disassociation may necessitate reducing overall length of meditations and periods of silent practice. Modifying the environment, time of therapy, intensity, etc. should be considered and these issues could be considered as questions for empirical study. It was suggested that CAM may have an impact on traditional treatment effectiveness, loss to follow up, number of required sessions, and patient adherence to standard therapy.
Sleep is another important issue for PTSD and outcome measures should include this domain. Similarly, there may be promise in evaluating outcome measures which focus on pain, treatment adherence, anxiety, adjustment issues, adverse effects, family and social functioning, depression and other co-morbidities. The potential of CAM as an adjunctive therapy to more proven therapies needs to be addressed. In addition, CAM may offer some Veterans a more acceptable avenue for entering care than more evidence-based therapies. Studies should examine whether offering CAM increases uptake of and retention in more proven therapies such as prolonged exposure therapy.
Self- administered and health care provider-administered approaches should be included. We need better descriptive / observational data. As noted, a challenge is that CAM is not coded consistently in the medical record. PTSD chronicity also merits consideration. Veterans may receive VA services for PTSD well after the initial traumatic exposure (>1 Yr). Fidelity of treatment is an important challenge in a clinical study. We also need to have better measures of CAM treatment fidelity.
Also, it was recommended that it would be premature to initiate large randomized trials of CAM treatments before we have worked out key methodological issues such as fidelity of treatment, outcome measures, and understanding contextual effects. Intent to treat analysis may not be the best approach for CAM therapies. Measuring adherence is important.
CAM therapy can have patient benefits even without treatment efficacy. We should attempt to understand these as well. In CAM study designs, many sham control procedures are difficult and may not be an appropriate control strategy.
Existing studies of non-CAM therapies such as prolonged exposure has often used relaxation therapy as a control, giving us evidence that relaxation therapy in isolation is not as effective as prolonged exposure.
Recommendations / Next Steps
The VA Office of Research and Development (ORD) is in the process of reviewing 21 applications for the recent Request for Application (RFA) focused on meditative based treatments for PTSD. Depending on scientific review and available funding it is anticipated that up to 3 projects will be supported and will begin in the fall of 2011. The VA Office of Research and Development has a continuing interest in this topic and encourages investigators to apply for support through merit review mechanisms.
Clinical Issues / Demonstration projects
VA also will fund demonstration projects to determine the feasibility of incorporating meditation into VA mental health care for PTSD and to examine outcomes for at least two forms of meditation. Demonstration projects also will provide some information on the impact of various contextual factors, such as sequencing of meditation with other evidence-based treatments, provider type, setting, and context, on patient CAM outcomes. Potential adverse events associated with CAM treatments can also be monitored.
A meeting participant noted, based on his experience treating active duty PTSD patients, that many of them have pain in some form, such as persistent headaches. Patients with chronic pain are distracted from living a normal life style, and for patients with PTSD it is a reminder of their injury. In this state, incorporating meditation may be difficult. Based on his experience, acupuncture appeared to provide benefit for these patients.
Questions suggested for consideration in the demonstration projects:
- Which treatments show promise? What is the variation in practice?
- What levels of improvement are relevant for PTSD? What are acceptable outcome measures and what are the clinically important effect sizes?
- Could evaluate those who have sub-threshold PTSD (PTSD symptoms that do not meet full criteria for a PTSD diagnosis).
- Understand links to primary care and other clinical services
- How can we use CAM more effectively?
- Do CAM modalities create a portal that opens patients up to other treatments?
- What are the barriers to engagement in current PTSD treatments and how might CAM address these?
- What are the gaps in our current treatment of PTSD? What is missing in standard methods of treatment?
- What are the risks of CAM? Will CAM raise or lower patient or public confidence in the VA health system?
- What are the risks for using/not using CAM in terms of getting and retaining patients?
Recommendations / Next Steps
The VA Office of Mental Health is pursuing development of clinical demonstration projects which would examine current treatment and practice of meditation for PTSD at 4 to 8 sites. Meeting participants identified the following important issues for consideration.
- Need for developing CAM manuals and the movement towards standardized versions of CAM.
- Leverage existing activities: use common measures across sites
- Develop plans if there are a lack of qualified instructors for CAM
- Acceptability; convincing health care providers and systems of potential benefits particularly for veterans with PTSD.
