UnlabelledNonspecific chronic spinal pain (NSCSP) is highly disabling. Current conservative rehabilitation commonly includes physical and behavioral interventions, or a combination of these approaches. Physical interventions aim to enhance physical capacity by using methods such as exercise, manual therapy, and ergonomics. Behavioral/psychologically informed interventions aim to enhance behaviors, cognitions, or mood by using methods such as relaxation and cognitive behavioral therapy. Combined interventions aim to target physical and also behavioral/psychological factors contributing to patients' pain by using methods such as multidisciplinary pain management programs. Because it remains unclear whether any of these approaches are superior, this review aimed to assess the comparative effectiveness of physical, behavioral/psychologically informed, and combined interventions on pain and disability in patients with NSCSP. Ten electronic databases were searched for randomized controlled trials (RCTs) including participants reporting NSCSP. Studies were required to have an "active" conservative treatment control group for comparison. Studies were not eligible if the interventions were from the same domain (eg, if the study compared 2 physical interventions). Study quality was assessed used the Cochrane Back Review Group risk of bias criteria. The treatment effects of physical, behavioral/psychologically informed, and combined interventions were assessed using meta-analyses. Twenty-four studies were included. No clinically significant differences were found for pain and disability between physical, behavioral/psychologically informed, and combined interventions. The simple categorization of interventions into physical, behavioral/psychologically informed, and combined could be considered a limitation of this review, because these interventions may not be easily differentiated to allow accurate comparisons to be made. Further work should consider investigating whether tailoring rehabilitation to individual patients and their perceived risk of chronicity, as seen in recent RCTs for low back pain, can enhance outcomes in NSCSP.PerspectiveIn this systematic review of RCTs in NSCSP, only small differences in pain or disability were observed between physical, behavioral/psychologically informed, and combined interventions.Copyright © 2016 American Pain Society.
