 This study will evaluate: 1 the TCM diagnostic differentiation patterns of people who have PTSD as defined by the Diagnostic and Statistical Manual, 4th edition; 2 if an acupuncture treatment approach is acceptable to people with PTSD; and 3 if an acupuncture treatment approach is associated with a reduction in PTSD symptoms that is comparable to that of standard treatments. Because symptoms of depression, insomnia, and pain are often associated with PTSD, we will also evaluate the potential benefit of an acupuncture approach to depression, insomnia, and pain symptoms in people with PTSD.
