Yoga Pranayama Intervention for PTSD Criteria Symptoms in Veterans
An Interventional, Single Arm Study
Kelly F Doyle, DNP-C, PMHNP
Margaret Knight, PhD, PMHCNS-BCProject Chair
Background Statement
¤ PTSD has been identified by the House Committee on Veterans Affairs as one of the signature wounds of Veterans returning from OEF/OIF
¤ In 2005, 14 years after the Gulf War, Veterans reported PTSD rates of 15.2%
¤ According to the Department of Veterans Affairs Strategic Plan, rates of PTSD are steadily rising within the Veteran population.
(Department of Veterans Affairs Strategic Plan Refresh Fiscal Year 2011-2015, 2011).
Background
¤ In 2012, Department of Defense (DoD) spent approximately $294 million and VA spent approximately $3 billion on PTSD care for service members and veterans (IOM, 2014)
¤ Rates of PTSD per VA diagnostic data are above 30% in Viet Nam and combat veteran populations (U.S. Department of Veteran Affairs, 2012)
¤ First line treatment is currently pharmacological (SSRI, alpha-1 adrenergic blockers, benzodiazepines), but not consistently effective.
¤ Difficult to treat, many resistant symptoms such as criteria D & E (APA, 2012)
Statistics and Epidemiology
¤ alarming rise in MH disorders including PTSD related veteran suicides – est.22/day (U.S. Department of Veteran Affairs, 2012)
¤ OEF/OIF prevalence 13.8% (Tanielian et al., 2008)
¤ Gulf War – 12.1% (Kang, et al., 2003)
¤ *(NVVRS) showed a lifetime PTSD prevalence of 30.9 % among male and 26.9% among female Vietnam theater Veterans.
*Using DSM-IV criteria
IOM & DoD Recommendations
¤ IOM call for more research into forms of contemplative neuroscience interventions for PTSD (IOM, 2014)
¤ VA strategic plan calling for more research for PTSD interventions. (Office of the Secretary: Department of Veterans Affairs Strategic Plan Refresh Fiscal Year 2011-2015., 2011)
Intervention Background
¤ Clinical guidelines for yoga interventions are still in their infancy
¤ Past studies – distinguishing different forms of yoga in a consistent way, combining many types/styles in one intervention
¤ Lack of useful lexicon hampers developing unifying theory (Brown, 2005a)
¤ Recently investigators are making an effort to: ¤ improve study design ¤ increase randomization and generalizability¤ and formally assess comorbidities of participants I screening that
could potentially serve as confounding variables
Intervention Background
¤ Few effective evidence-based options: cognitive processing therapy (CPT) and prolonged exposure therapy (PE) cognitive behavioral therapy (CBT) (Karlin, Ruzek, & Chard, 2010) Eye Movement and Desensitization and Reprocessing (EMDR)¤ 2-3 weeks before any effect detected ¤ Can be iatrogenic - can induce intrusive thoughts, difficult memories,
and emotions. (Raza & Holohan, 2015) ¤ far less effect on the hyper-arousal symptom criteria (E)
¤ Drop out rates from these therapies are as high as 54.0% (Brown, 2012) EMDR better, faster results.
¤ In many studies, yoga with pranayama, has been shown to be more effective than existing EB treatments for residual and resistant symptoms (Pascoe & Bauer, 2015)
Literature Review
¤ Yoga with pranayama (breathing; Sanskrit translation – “Extension of the life force”) shows more significant effect size than mixed forms (Johnston et al., 2015)
¤ Three studies that used only yoga pranayama, all found that: ¤ yoga-breath interventions may help relieve distressing, treatment resistant
symptoms and psychological distress of PTSD¤ reduces the prevalence of PTSD-like symptoms (Descilio et al., 2010; Kim et al., 2013;
Seppala et al., 2014).
¤ Significant decreases in treatment resistant hyper-arousal symptoms on PCL-5 after six week sessions (Mitchell et al. 2014; van der Kolk et al., 2014)
Literature Review
¤ Improvement with autonomic dysfunction, negative affect, sleep, and emotion regulation (Seppala et al., 2014)
¤ Improvement in associated symptoms of anxiety, “re-experiencing,” and depression (Streeter et al., 2010)
¤ Seven recent controlled trials using pranayama showed significant improvements in PTSD symptoms post-intervention.
¤ Body-based contemplative practices used as prescribed therapeutic interventions are highly preferred and indicated for high-trauma populations such as war veterans and torture survivors (Britton et al., 2013)
Problem Statement
¤ As noted, not all symptoms are treated effectively with medication –most will persist.
¤ Resistant symptoms treated with PE, CPT, and EMDR as well as symptom targeted therapies (sleep, anxiety) not effective.
¤ Treating target resistant criteria (D and E) (the negative affect and hyper-arousal symptoms) is a problem in treatment
¤ Poor outcomes with current – PE and CPT 59% of individuals still had PTSD after 12 weeks of treatment, and 78% remained symptomatic at 6-month follow-up (Schnurr, et al., 2007)
Research Question
Does a six-week trauma-sensitive yoga breathing (Ashtanga Pranayama) intervention show a clinically significant
reduction of symptoms in a veteran population diagnosed with PTSD?
Screening Guidelines - Inclusion

Screening Guidelines - Exclusion
Exclusion Criteria
¤ unstable medical condition
¤ current or lifetime bipolar I or psychotic disorder
¤ pregnancy or breastfeeding status

Framework

Intervention
Demographics
Six week-Twelve session Ashtanga Pranayama Yoga
45 minute sessions
Dependent Variables
PCL-5 scores
The State-Trait Anxiety Inventory (STAI)
The Pittsburgh Sleep Quality Index (PSQI)
Screening scores on affect and mood.
Monitor Scores at start,
completion, and one month follow-
up
Does a six-week, trauma-sensitive yoga breathing
intervention show a clinically significant reduction of symptoms in a veteran
population diagnosed with PTSD?
Design
¤Quasi-experimental Design¤ Single arm interventional study¤ No control group
Sample and Setting
¤ Thirty veterans with clinical or sub-clinical PTSD
¤ Two intervention groups – two groups of fifteen
¤ Durham VA Medical Center or nearby CBOC
Instruments
¤ A multimethod approach - self-report symptom measures and psychophysiological testing to assess the effects of Ashtanga Pranayama yoga:
¤ Posttraumatic Stress Disorder Checklist for DSM-5 ¤ MASQ = Mood and Anxiety Symptoms Questionnaire ¤ The Pittsburgh Sleep Quality Index (PSQI) ¤ Salivary cortisol levels (if possible)
Intervention
¤ Ashtanga Pranayama group/class
¤ Two groups of fifteen, run sequentially
¤ Expert consultant design of Ashtanga Pranayama program
¤ 60 minute class, six weeks, two classes a week.
¤ 15 minute home practice program to do twice a week
Data Analysis
¤ Differences in the pre-intervention to post-intervention measurements
¤ Baseline and post data will be assessed
Limitations
¤ Challenges scheduling teaching time for classes
¤ Homogeneity of population
¤ Possible pre-study comorbidities in participants
¤ Small sample size
¤ Recruiting participants – isolation is significant barrier for PTSD population
¤ Drop out rates
