| Abstract: |
| Objective: To explore the effectiveness and safety of acupuncture in patients with post-stroke dysphagia by an update meta-analysis. Methods: Potentially eligible RCTs aimed to evaluate the effects of acupuncture vs. non-acupuncture treatments, such as rehabilitation training or routine medication on the swallowing difficulty after stroke were searched from PubMed, Cochrane Library, China National Knowledge Infrastructure, and other database from the earliest record to June 2016. Patient demographics, regimens for acupuncture, type of controls, methods of randomization, and measurements of the clinical symptoms of dysphagia were retrieved. The relative risk (RR) and 95% confidence interval (CI) of effective rate of dysphagia was calculated after intervention performed following admission. Subgroup analyses and a meta-regression analysis were performed to describe the heterogeneity. Results: Twenty-nine RCTs comprising 2,190 patients were included. The included studies had a medium quality grade based on the Consolidated Standards of Reporting Trials (CONSORT) and Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) checklist. Acupuncture therapy provided a higher effective rate compared with non-acupuncture treatments [RR=1.33, 95% confidence interval (CI), 1.25 to 1.43]. Subgroup and meta-regression analyses suggested that acupuncture intensity and measurement method were main sources of heterogeneity and resulted in a significant difference for pooled effect size. No severe adverse events were documented in these RCTs. Conclusions: Our meta-analysis provides a new evidence supporting the efficacy and safety of acupuncture in treatment to post-stroke dysphagia in short-term compared with rehabilitation or medication. More high-quality and large-scale research studies are needed. |
