Acupuncture for Post-Stroke Dysphagia: A Clinical Study

Overview

Employing a nested design, a partially randomized preference study (Study II) is embedded within a prospective, multicenter cohort study (Study I). The cohort study, with acupuncture as the exposure factor, explores the clinical efficacy and health economic value of different integrated Chinese and Western medicine treatment protocols. The nested partially randomized preference study of different acupuncture protocols generates high-level evidence through randomized cohorts while supplementing real-world decision-making with preference cohort data.

A nested design was employed, incorporating a partially randomized preference study (Study 2) within a prospective, multicenter cohort study (Study 1). Study 1 (Main Cohort): A prospective, multicenter cohort study will enroll patients with post-stroke dysphagia meeting inclusion and exclusion criteria who present at the research center between January 2026 and December 2027. Acupuncture will serve as the exposure factor, naturally forming two cohorts. Primary efficacy outcomes will assess clinical efficacy of acupuncture interventions for PSD, clarify therapeutic advantages of precision acupuncture protocols, explore treatment benefits across PSD subgroups, and evaluate the efficacy and health economic value of diversified integrated Chinese-Western medical approaches to inform guideline updates with evidence-based data. Study 2 (Embedded Study): Employing a prospective, multicenter, partially randomized preference study, we enrolled patients with post-stroke dysphagia meeting inclusion/exclusion criteria who visited the research center between January 2026 and December 2027. Acupuncture intervention grouping followed a "preference-priority, random-supplement" strategy. Specifically: Patients with clear preferences were assigned to their chosen group; those without preferences were randomized 1:1 to either the conventional acupuncture group or the "Tongguan Liqiao" acupuncture group. Swallowing function served as the primary efficacy indicator to evaluate the clinical efficacy of different acupuncture intervention protocols for treating PSD.
