It is well documented that comorbid post-traumatic stress disorder (PTSD) in chronic pain is associated with a more severe symptom profile with respect to pain, disability and psychological distress. However, very few intervention studies exist targeting both PTSD and pain. The current study is the first randomized controlled trial evaluating the effect of the body-oriented trauma approach of Somatic Experiencing (SE) for comorbid PTSD and low back pain. Although the method is well recognized by clinicians and widely used, SE still needs to be tested in a randomized clinical trial in comparison with an active control group.

There have been recent advances in neuroscience that challenge the completeness of a purely cognitive behavioral model—particularly when dealing with the impact of trauma. What we are learning now is that trauma is not just something that impacts our cognition and behaviors alone.
