Abstract

Background: Low back pain (LBP) and comorbid post-traumatic stress symptoms (PTSS) are common after traumatic injuries, and a high level of PTSS is associated with more severe pain and pain-related disability. Few randomised controlled trials (RCT) exist targeting comorbid PTSS and chronic pain, and only one has assessed the effect of somatic experiencing.

Objective: The aim of this study was to assess the effect of somatic experiencing (up to 12 sessions) + physiotherapeutic intervention (4-8 sessions) (SE+PT) compared with the physiotherapeutic intervention alone (4-8 sessions) (PT) for pain-related disability in LBP with comorbid PTSS.

Methods: The study was a two-group RCT in which participants (n=114) were recruited consecutively from a large Danish Spine Centre. Patients were randomly allocated to either SE+PT or PT alone. Outcomes were collected at baseline before randomisation, 6 and 12-month post-randomisation. The primary outcome was pain-related disability as measured with the modified version of the Roland Morris Disability Questionnaire at 6-month post-randomisation. Secondary outcomes were PTSS, pain intensity, pain-catastrophising, kinesiophobia, anxiety and depression.

Results: No significant group differences were found on any of the outcomes at any timepoints. Both groups achieved a significant reduction in pain-related disability (20-27%) as measured by the Roland Morris Disability Questionnaire at 6 and 12-month follow up. Also, both groups achieved a small reduction in PTSS.

Conclusions: Although significant effects were achieved for both groups, the additional SE intervention did not result in any additional benefits in any of the outcomes.
