Evaluation of a Yoga Intervention for Post-Traumatic Stress Disorder

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.

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.

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.
