Effects of meditation on pain intensity, physical function, quality of life and depression in adults with low back pain – A systematic review with meta-analysis
Abstract
Background: Low back pain (LBP) is a common biopsychosocial health problem. Meditation may provide a complementary treatment option for LBP patients. Objectives: The aim of this systematic review with meta-analysis was to examine the effects of meditation on pain intensity, functional disability, quality of life, and depression in LBP populations. Methods: This systematic review was conducted according to the PRISMA Guidelines. PubMed, Web of Science, CENTRAL, CamQuest and PubPsych were searched up to a publication date of June 2020. Inclusion criteria were RCTs or non-RCTs with LBP patients, aged at least 18 years, the application of a specific meditation technique, and pain intensity and/or functional disability as outcomes. Pooled SMDs were calculated at post-treatment and follow up. The Cochrane risk-of-bias tool was used to estimate risk of bias. The overall quality of evidence was assessed using the GRADE approach. Results: 12 studies with a total of 1005 participants were included in this review. Compared to controls, meditation solely showed a significant positive effect on pain intensity (SMD = −0.27 [CI −0.43; −0.11]; p = 0.001; based on 10 studies with 934 participants) and physical quality of life (SMD = 0.21 [CI 0.07; 0.36]; p = 0.005; based on 5 studies with 756 participants) at post-treatment. At follow up (mean 20 weeks, range 4–52) there were no significant effects anymore. The quality of the evidence was moderate due to study limitations and imprecision. Conclusions: Meditation seems to be promising with regard to reducing short-term pain intensity in patients with LBP. However, additional well-designed and large trials are required in order to draw more reliable conclusions.
