Evaluation of a Yoga Intervention for Post-Traumatic Stress Disorder (EYIPTSD)

March 19, 2013 updated by: Sat Bir Khalsa, PhD, Brigham and Women's Hospital
The main objective of this preliminary randomized controlled clinical trial is to establish efficacy and feasibility of a yoga-based treatment for PTSD in military veterans as compared to a delayed yoga treatment (waitlist control) group. Secondary objectives are to evaluate PTSD characteristics that may also be improved with the treatment and acceptability and compliance with the treatment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Specific Aims:

  1. To evaluate the hypothesis that a 10-week yoga-based intervention will reduce PTSD severity to a statistically and clinically significant degree relative to a pretreatment baseline evaluation and to a waitlist control group.
  2. To evaluate the hypothesis that PTSD patients will show improvement in regulation of physiological arousal in the autonomic nervous system relative to pretreatment.
  3. To evaluate that hypothesis that symptoms associated with PTSD such as depression, anxiety, insomnia and quality of life will also be improved.
  4. To evaluate the hypothesis that military veterans with PTSD can be successfully recruited into a yoga intervention study and will find the intervention acceptable and tolerable and will exhibit high compliance.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male and female military veterans and active duty military personnel aged 18 and older
  • A DSM IV diagnosis of post-traumatic stress disorder
  • Potential subjects on medications are eligible to participate in the study
  • Potential subjects who receive ongoing medical or psychological treatment are eligible to participate in this study as long as these treatments do not include more than one hour weekly of relaxation and mind-body based stress reduction strategies (strategies directly related to meditation and yoga)
  • Potential subjects are eligible to participate in this study if they have sufficient mental and physical ability to fully participate in the parameters of the study. Subjects must be able to understand and comply with instructions in the group yoga sessions and home practice, complete questionnaires, participate in clinical interviews, and take part in all data collection activities. Subjects with severe mental or physical concerns that may prevent them from understanding and/or complying with the treatment will be excluded. For example, potential subjects confined to wheelchairs will not be eligible, although subjects with artificial limbs who are able to reasonably participate in the intervention may be deemed eligible. These determinations will be made during discussions with potential subjects on a case by case basis during the screening process

Exclusion Criteria:

  • Potential subjects are ineligible if pregnant and in their third trimester.
  • Potential subjects are ineligible if they are confined to a wheel chair.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Yoga treatment
Behavioral: Yoga treatment
The 10-week Kripalu-style yoga treatment will consist of 20 biweekly 90-minute group training/practice sessions. In addition, subjects will also receive CD's and written instructions for the daily 15-minute sessions, which they will use to guide them through the yoga procedures to be done at home.
Other Names:
  • Kripalu Yoga
No Intervention: Waitlist
Waitlist control, no active treatment, treatment as usual, active treatment offered after waitlist control period. This study began as a single arm treatment trial and then transitioned to a randomized controlled trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
