Background: The Mulligan method of manual therapy advocates the use of 'mobilization with movement (MWM)' techniques to effectively manage peripheral joint 'positional fault' dysfunctions.
Objectives: To provide an updated evidence-based systematic review and meta-analysis regarding the effectiveness of MWM techniques.
Data sources: PubMed, EBSCOhost, PEDro, Cochrane Library and Google Scholar between 1st August 2008-31st August 2017.
Study selection: Two reviewers applied the population intervention comparison outcome (PICO) question to screen the studies for this review. Only RCTs/CCTs were included.
Data extraction: Information on study design, subjects, intervention, outcome measures and efficacy results were extracted. Methodological quality was independently assessed by two reviewers using the PEDro Scale.
Data synthesis: Sixteen studies with 576 participants were included in four separate meta-analyses for pain and disability. The I2 index assessed the heterogeneity between studies.
Results: MWMs have demonstrated statistically significant improvements against sham treatment, passive and control intervention techniques for pain [mean difference (95%CI):-16.12 (-19.77, -12.48) & I=72%] and disability [mean difference (95%CI):-17.51 (-22.84, -12.19) 2 2 2 2 & I=88%] or against another manual therapy treatment [pain mean difference (95%CI): -10.43 (-11.38, -9.48) & I=0%], however not against another manual therapy treatment for disability. The clinical significance of the pooled differences was compared against Minimal Clinically Important Difference values.
Limitations: No long-term effectiveness data were identified in any of the included studies.
Conclusions and implications of key findings: The overall post-intervention short-term statistical and clinical significance of MWM techniques has been verified, although the high heterogeneity identified may require further validation of those methods. Systematic review registration number: PROSPERO 2016:CRD42017071595.
