Evidence for Dry Needling in the Management of Myofascial Trigger Points Associated With Low Back Pain

OBJECTIVE: To evaluate the current evidence of the effectiveness of dry needling
of myofascial trigger points (MTrPs) associated with low back pain (LBP). DATA SOURCES: PubMed, Ovid, EBSCO, ScienceDirect, Web of Science, Cochrane Library,
CINAHL, and China National Knowledge Infrastructure databases were searched until
January 2017. STUDY SELECTION: Randomized controlled trials (RCTs) that used dry
needling as the main treatment and included participants diagnosed with LBP with
the presence of MTrPs were included. DATA EXTRACTION: Two reviewers independently
screened articles, scored methodologic quality, and extracted data. The primary
outcomes were pain intensity and functional disability at postintervention and
follow-up. DATA SYNTHESIS: A total of 11 RCTs involving 802 patients were
included in the meta-analysis. Results suggested that compared with other
treatments, dry needling of MTrPs was more effective in alleviating the intensity
of LBP (standardized mean difference [SMD], -1.06; 95% confidence interval [CI],
-1.77 to -0.36; P=.003) and functional disability (SMD, -0.76; 95% CI, -1.46 to
-0.06; P=.03); however, the significant effects of dry needling plus other
treatments on pain intensity could be superior to dry needling alone for LBP at
postintervention (SMD, 0.83; 95% CI, 0.55-1.11; P<.00001). CONCLUSIONS: Moderate
evidence showed that dry needling of MTrPs, especially if associated with other
therapies, could be recommended to relieve the intensity of LBP at
postintervention; however, the clinical superiority of dry needling in improving
functional disability and its follow-up effects still remains unclear.
