Purpose: To assess the efficacy and safety of MBSR in patients with low back pain. Data Sources: Searches of MEDLINE/PubMed, Scopus, the Cochrane Library, and PsycINFO to 15 June 2016. Study Selection: Randomized controlled trials (RCTs) that compared MBSR with usual care or an active comparator and assessed pain intensity or pain-related disability as a primary outcome in patients with low back pain. Data Extraction: Two reviewers independently extracted data on study characteristics, patients, interventions, outcome measures, and results at short-and long-term follow-up. Risk of bias was assessed using the Cochrane risk-of-bias tool. Data Synthesis: Seven RCTs involving 864 patients with low back pain were eligible for review. Compared with usual care, MBSR was associated with short-term improvements in pain intensity (4 RCTs; mean difference [MD],-0.96 point on a numerical rating scale [95% CI,-1.64 to-0.34 point]; standardized mean difference [SMD],-0.48 point [CI,-0.82 to-0.14 point]) and physical functioning (2 RCTs; MD, 2.50 [CI, 0.90 to 4.10 point]; SMD, 0.25 [CI, 0.09 to 0.41 point]) that were not sustained in the long term. Between-group differences in disability, mental health, pain acceptance, and mindfulness were not significant at short-or long-term follow-up. Compared with an active comparator, MBSR was not associated with significant differences in short-or long-term outcomes. No serious adverse events were reported. Limitation: The number of eligible RCTs was limited; only 3 evaluated MBSR against an active comparator. Conclusion: Mindfulness-based stress reduction may be associated with short-term effects on pain intensity and physical functioning. Long-term RCTs that compare MBSR versus active treatments are needed in order to best understand the role of MBSR in the management of low back pain. Primary Funding Source: None.
