THE EVALUATION VALUE OF VIDEOFLUOROSCOPIC SWALLOWING STUDY IN DYSPHAGIA AFTER STROKE

Introduction: To clarify evaluation value of videofluoroscopic swallowing study (VFSS) in dysphagia after stroke. Materials and methods: A total of 106 stroke patients hospitalized in our hospital from January 2019 to December 2021 were enrolled. According to the definition of dysphagia after stroke in the Scottish National Guidelines, 106 patients with this symptom were identified. According to the principle of randomization and single-blind control, they were divided into observation group and control group, with 53 cases in each. The control group received routine swallowing rehabilitation therapy, while the observation group received VFSS examination on the basis of the above-mentioned routine rehabilitation therapy, once a day. After 4 weeks of treatment, water swallow test and Rosenbek aspiration degree grading were assessed between two groups before and after treatment to evaluate treatment efficacy, pharyngeal cavity contraction rate and pharyngeal cavity contraction time. Results: After treatment, pharyngeal cavity contraction rate and duration in two groups presented depletion relative to those before treatment, and pharyngeal cavity contraction rate and duration in observation group presented depletion relative to controls (P< 0.05). Water swallow test grading in two groups presented depletion relative to those before treatment (P< 0.05), and grading in observation group presented depletion relative to controls after treatment (P< 0.05). The observation group was better than the control group in terms of Rosenbek aspiration degree and clinical complications (P< 0.05). The total effective rate in the treatment group was 94.34%, higher than in the control group (86.79%) (P< 0.05). Conclusion: VFSS can accurately assess dysphagia degree after stroke and can significantly improve rehabilitation efficacy of patients with dysphagia after stroke, reduce the of aspiration degree, and decrease occurrence of complications.

Automated summary

The study aimed to evaluate the value of videofluoroscopic swallowing study (VFSS) in dysphagia after stroke. The results showed that VFSS can accurately assess the degree of dysphagia after stroke and improve rehabilitation efficacy, reducing aspiration and complications.
