Abstract:

Objective To evaluate the effect of mirror therapy on lower-limb motor, balance and walking of stroke patients.
Methods Randomized controlled trails (RCTs) about mirror therapy for lower limb function after stroke were recalled in PubMed, Cochrane Library, EMbase, Medline complete, CNKI, Wanfang Data, VIP and CBMdisc. Meta-analysis was conducted using RevMan 5.3 software for eligible RCTs.
Results A total of twelve studies were retrieved, including 590 patients. Mirror therapy improved the scores of Fugl-Meyer Assessment-Lower Extremity (MD = 6.67, 95%CI 5.60 to 7.74; Z = 12.20, P< 0.001), Brunnstrom stages (MD = 0.55, 95%CI 0.28 to 0.82;Z = 3.98, P< 0.001), Berg Balance Scale (MD = 3.45, 95%CI 1.40 to 5.50;Z = 3.30, P = 0.001), mini-BESTest (MD = 1.49, 95%CI 0.65 to 2.33; Z = 3.48, P< 0.001), Brunnel Balance Assessment (MD = 0.66, 95%CI 0.10 to 1.22;Z = 2.32, P = 0.02). However, it was not significant for 10-meter Walking Test (MD = 0.03, 95%CI -0.04 to 0.11; Z = 0.88, P = 0.38) and Timed "Up and Go" Test (MD = -1.43, 95%CI -4.31 to 1.45; Z = 0.97, P = 0.33).
Conclusion Mirror therapy can improve lower extremity motor function after stroke significantly, and somehow for balance. Further research is needed to explore its effects on walking.
