Meditation for adults with non-specific low back pain: a systematic review and meta-analysis.
OBJECTIVES
We aim to determine the effectiveness of meditation for adults with non-specific low back pain.


METHODS
We searched PubMed, EMBASE, PEDro, Scopus, Web of Science, Cochrane Library, and PsycINFO databases for randomized controlled trials that investigated the effectiveness of meditation in adults with non-specific low back pain. Two reviewers rated risk of bias using the PEDro scale and the certainty of the evidence using the GRADE approach. Primary outcomes were pain intensity and disability.


RESULTS
We included eight trials with a total of 1,234 participants. Moderate-certainty evidence shows that meditation is better than usual care for disability at short-term (SMD = -0.22; 95% CI = -0.42 to -0.02). We also found that meditation is better than usual care for pain intensity at long-term (SMD = -0.28; 95% CI = -0.54 to -0.02). There is no significant difference for pain intensity between meditation and minimal intervention or usual care at short and intermediate-term. We did not find differences between meditation and minimal intervention for disability at intermediate-term or usual care in any follow-up period.


CONCLUSIONS
We found small effect sizes and moderate-certainty evidence that meditation is slightly better than minimal intervention in the short-term for disability. Low-certainty of evidence suggests that meditation is slightly better than usual care for pain in the long-term. Meditation appears to be safe with most trials reporting no serious adverse events.
