In this study, we are evaluating the effectiveness of a yoga intervention to treat
posttraumatic stress disorder (PTSD), its associated symptoms of chronic pain and insomnia,
and biological and physiological responses to trauma and PTSD in women Veterans who
experienced military sexual trauma (MST). If effective, this yoga intervention could reduce
PTSD symptoms and chronic pain, improve sleep quality, and decrease the body's automatic
"fight or flight" stress response and the damage this stress response causes in the body,
including heart disease and diabetes. This intervention could improve these women Veterans'
quality of life and social functioning, for example, going to work and having satisfying
relationships with family and friends. This study may support an innovative, complementary
and alternative PTSD treatment for women Veterans who experienced MST. This new,
evidence-based PTSD treatment could supplement current PTSD treatments. Clinical guidelines
for this yoga intervention could be implemented nationally in the VA health care system.
