To conduct a systematic review and meta-analysis to assess the impact of transcranial electrical stimulation (TES), proposed as a potential therapy for post-stroke dysphagia, on swallowing function in stroke survivors.
The PubMed, Embase, Web of Science, and Cochrane Library databases were searched for relevant studies on TES for post-stroke dysphagia. Search results were reviewed following PRISMA guidelines, and the following data were extracted from included studies: study characteristics, demographics, and outcomes. Bias was assessed using the Cochrane tool. Heterogeneity and effect sizes were analysed using I statistics and appropriate effects models. The study protocol was registered with PROSPERO (registration No. CRD42024578243).
Six randomized controlled trials met the inclusion criteria (I = 0.0%). The meta-analysis indicated a significant improvement in dysphagia with TES (standardized mean difference [SMD] 0.43, 95% confidence interval [CI] 0.13, 0.73). Subgroup analysis suggested that low-intensity TES was effective (SMD 0.46, 95% CI 0.09, 0.82), whereas high-intensity TES showed no significant improvement (SMD 0.37, 95% CI -0.17, 0.91). No publication bias was detected.
TES may improve swallowing in stroke patients, with potential benefits from low-intensity protocols.
系统评价和荟萃分析评估经颅电刺激（TES）对脑卒中后吞咽障碍患者吞咽功能的影响，TES 被提议作为一种潜在的治疗方法。
检索 PubMed、Embase、Web of Science 和 Cochrane Library 数据库中关于 TES 治疗脑卒中后吞咽障碍的相关研究。按照 PRISMA 指南对检索结果进行评价，并从纳入研究中提取以下数据：研究特征、人口统计学和结局。使用 Cochrane 工具评估偏倚。使用 I ²统计量和适当的效应模型分析异质性和效应大小。该研究方案在 PROSPERO（注册号：CRD42024578243）中进行了注册。
纳入的 6 项随机对照试验符合纳入标准（I=0.0%）。荟萃分析表明 TES 可显著改善吞咽障碍（标准化均数差[SMD]0.43，95%置信区间[CI]0.13，0.73）。亚组分析表明，低强度 TES 有效（SMD 0.46，95% CI 0.09，0.82），而高强度 TES 无明显改善（SMD 0.37，95% CI-0.17，0.91）。未发现发表偏倚。
TES 可能改善脑卒中患者的吞咽功能，低强度方案可能具有潜在益处。
