OBJECTIVE: To evaluate the mean treatment effect of mirror therapy on motor
function of the upper extremity in patients with stroke.
DATA SOURCES: Electronic
databases, including the Cochrane Library, PubMed, MEDLINE, Embase and
CNKSystematic, were searched for relevant studies published in English between 1
January 2007 and 22 June 2017. STUDY SELECTION: Randomized controlled trials and
pilot randomized controlled trials that compared mirror therapy/mirror box
therapy with other rehabilitation approaches were selected. DATA EXTRACTION: Two
authors independently evaluated the searched studies based on the
inclusion/exclusion criteria and appraised the quality of included studies
according to the criteria of the updated version 5.1.0 of the Cochrane Handbook
for Systematic Review of Interventions. DATA SYNTHESIS: Eleven trials, with a
total of 347 patients, were included in the meta-analysis. A moderate effect of
mirror therapy (standardized mean difference 0.51, 95% confidence interval (CI)
0.29, 0.73) on motor function of the upper extremity was found. However, a high
degree of heterogeneity (chi2 = 25.65, p = 0.004; I2 = 61%) was observed. The
heterogeneity decreased a great deal (chi2 = 6.26, p = 0.62; I2 = 0%) after 2
trials were excluded though sensitivity analysis. CONCLUSION: Although the
included studies had high heterogeneity, meta-analysis provided some evidence
that mirror therapy may significantly improve motor function of the upper limb in
patients with stroke. Further well-designed studies are needed.
