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.
