Objective: To evaluate the effect of functional electrical stimulation on lower-limb function in stroke patients with hemiplegia. Methods: Through the computer search PubMed, Cochrane, web of science, CNKI, Wanfang, Weipu and other databases for randomized controlled trials of functional electrical stimulation on improving lower-limb function of stroke patients with hemiplegia. After screening literature, quality evaluation and data extraction, meta-analysis was conducted. Results: A total of 13 randomized controlled trials were conducted in 643 patients. The results of meta-analysis showed that the intervention effect of FES group was better than that of routine group in improving lower-limb motor function [MD=4.78,95%CI (3.27,6.29),P<0.001], balance function [MD=8.88,95%CI (5.85,11.92),P<0.001] and activities of daily living [MD=16.74,95%CI (8.48,25.0),P<0.001] of stroke patients with hemiplegia. Conclusion: FES intervention on the lower-limb of stroke hemiplegic patients on the basis of routine rehabilitation is helpful to further improve the lower extremity motor function, balance function and daily life activity ability of the patients.
