  Abstract: Objective To investigate the efficacy of a severity-graded intervention protocol for post-stroke dysphagia based on Fiberoptic Endoscopic Evaluation of Swallowing (FEES) assessment. Methods This randomized controlled trial enrolled 72 patients with post-stroke dysphagia admitted to the 900th Hospital of PLA Joint Logistics Support Force from June 2024 to June 2025. Participants were divided into an experimental group and a control group. The experimental group received a stratified intervention based on three levels determined by Fiberoptic Endoscopic Evaluation of Swallowing (FEES) combined with the Penetration-Aspiration Scale (PAS), while the control group received standardized conventional rehabilitation therapy. Both groups underwent 4 weeks of treatment. The improvement in swallowing function and clinical efficacy were compared between the two groups. Results After 4 weeks of intervention, the overall response rate in the experimental group was significantly higher than in the control group (P<0.05). Compared to baseline, both groups showed significant reductions in the Penetration-Aspiration Scale score, swallowing function scores, and Water Swallow Test score (P<0.05), while scores on the Functional Oral Intake Scale and the Quality of Life scale showed significant increases compared to pre-treatment levels (P<0.05). Furthermore, the experimental group demonstrated significantly greater improvements in all scales compared to the control group (P<0.05). During the treatment period, the incidence of aspiration pneumonia in the experimental group (2.8%) was lower than that in the control group (13.9%), but the difference was not statistically significant (P = 0.076). Conclusion FEES-PAS guided personalized graded intervention significantly improves swallowing function in post-stroke dysphagia patients, effectively promoting functional recovery and demonstrating substantial clinical value for broader application.
