PainSci summary of Li 2014?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★☆☆☆?2-star ratings are for studies with flaws, bias, and/or conflict of interest; published in lesser journals. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.
This is a review of massage therapy for fibromyalgia that epitomizes the “garbage in, garbage out” problem with meta-analysis: there was virtually no research on this topic worth analyzing to begin with, and trying to pool the results of several weak studies is meaningless. To the extent that the study results are generally inconclusive and ambiguous, the conclusions of any review are going to have more to do with the authors’ opinions and biases than hard data. In this case, they report “significant” positive results without mentioning that they only mean “statistically significant,” and the effect size is barely-there — clinically insignificant. They also boast about traditional Chinese massage in the abstract, which is odd. And they fail to note that a much of the data did not even measure the effect on pain, just mood. So here’s my conclusion: whoop-de-doo. There’s really nothing here, except maybe massage for fibromyalgia being damned by faint, ambiguous praise.

BACKGROUND: Although some studies evaluated the effectiveness of massage therapy for fibromyalgia (FM), the role of massage therapy in the management of FM remained controversial.
OBJECTIVE: The purpose of this systematic review is to evaluate the evidence of massage therapy for patients with FM.
METHODS: Electronic databases (up to June 2013) were searched to identify relevant studies. The main outcome measures were pain, anxiety, depression, and sleep disturbance. Two reviewers independently abstracted data and appraised risk of bias. The risk of bias of eligible studies was assessed based on Cochrane tools. Standardised mean difference (SMD) and 95% confidence intervals (CI) were calculated by more conservative random-effects model. And heterogeneity was assessed based on the I(2) statistic.
RESULTS: Nine randomized controlled trials involving 404 patients met the inclusion criteria. The meta-analyses showed that massage therapy with duration ≥5 weeks significantly improved pain (SMD, 0.62; 95% CI 0.05 to 1.20; p = 0.03), anxiety (SMD, 0.44; 95% CI 0.09 to 0.78; p = 0.01), and depression (SMD, 0.49; 95% CI 0.15 to 0.84; p = 0.005) in patients with FM, but not on sleep disturbance (SMD, 0.19; 95% CI -0.38 to 0.75; p = 0.52).
CONCLUSION: Massage therapy with duration ≥5 weeks had beneficial immediate effects on improving pain, anxiety, and depression in patients with FM. Massage therapy should be one of the viable complementary and alternative treatments for FM. However, given fewer eligible studies in subgroup meta-analyses and no evidence on follow-up effects, large-scale randomized controlled trials with long follow-up are warrant to confirm the current findings.
