Patients with co-morbid chronic pain and post-traumatic stress disorder (PTSD) pose significant treatment challenges. This study evaluated the effectiveness of an interdisciplinary pain rehabilitation program (IPRP) in improving pain and PTSD outcomes, as well as reducing medication use. In addition, the mediating effect of pain catastrophizing, which is theorized to underlie the pain and PTSD comorbidity, was examined. Participants included 83 completers of an IPRP with chronic pain and a provisional PTSD diagnosis. Significant improvements were found for pain outcomes, PTSD symptomatology, depressive symptoms, physical performance, and medication use (i.e., opioids and benzodiazepines). At discharge, 86.7% of participants reliably improved in at least one key measure of functioning and 50.6% demonstrated reliable improvement in PTSD symptomatology. Change in pain catastrophizing mediated improvements in pain interference and PTSD symptomatology. Results support the potential utility of an interdisciplinary pain treatment approach in the treatment of patients with comorbid pain and PTSD.

检查疼痛康复对慢性疼痛和创伤后症状的有效性。

患有合并症的慢性疼痛和创伤后应激障碍（PTSD）的患者面临重大的治疗挑战。这项研究评估了跨学科疼痛康复计划（IPRP）在改善疼痛和PTSD结果以及减少用药方面的有效性。此外，还研究了理论上证明是疼痛和PTSD合并症基础的疼痛灾难性疾病的介导作用。参加者包括83名完成IPRP的慢性疼痛和PTSD临时诊断的人。发现在疼痛结局，PTSD症状，抑郁症状，身体机能和药物使用（即阿片类药物和苯二氮卓类药物）方面有显着改善。出院时，至少有一项关键功能指标和50位参与者中有86.7％的参与者可靠地得到了改善。有6％的人表现出PTSD症状的可靠改善。灾难性疼痛的变化介导了疼痛干预和PTSD症状的改善。结果支持跨学科疼痛治疗方法在合并症疼痛和PTSD患者治疗中的潜在效用。
