Background: Whether NMES helps the recovery of upper limb function in patients with hemiparesis has not been confirmed. We conducted this meta-analysis to examine the effectiveness of neuromuscular electrical stimulation (NMES) for upper limb hemiparesis after stroke.Methods: Data sources such as Pubmed, Embase and Cochrane library databases were searched for all relevant studies that were carried out before December 1, 2018.We selected the randomized controlled trials (RCTs) which included chronic and acute stroke patients with upper extremity dysfunction. Then the intervention group which applied NMES was compared with a control group without NMES. Results: A total of 16 RCTs involving 691 patients were discerned from 248 searched articles. According to the forest plot ,NMES had a significant benefit on FMA-ue scale(SMD=0.44,95%CI 0.13 to 0.74,P=0.006).Also, NMES was positive for ARAT(SMD=0.31,95%CI 0.05 to 0.58,P=0.019)and MAL-AOU(SMD=0.59,95%CI 0.15 to1.04,P=0.009),but not for wrist MAS(SMD=-0.12,95%CI -0.43 to 0.19,P=0.434) or BI(SMD=0.51,95%CI -0.65 to 1.66,P=0.392).Conclusion: NMES application has beneficial impacts on upper extremity motor function in patients with stroke. This study suggests that NMES ought to be applied as a beneficial rehabilitation means in improving the upper function.
