Abstract：Objective: To observe the geniohyoid muscle activity parameters and hyoid activity parameters in patients with dysphagia after stroke by real-time B/M ultrasound, and to explore its clinical value and application in the evaluation of dysphagia after stroke. Methods: Totally 30 patients with dysphagia after stroke in Taizhou Hospital of Zhejiang Province from January 2021 to December 2021 were selected as the observation group, and another 30 healthy subjects as the control group. Pharyngeal dysphagia was detected by pharyngography (VFSS) in all patients in the observation group. Pharynx ultrasonography was performed by the same ultrasound doctor in both groups. When all subjects swallowed 5 mL dilute fluid, the maximum distance, minimum distance and required time between hyoid and mandible were measured or calculated, hyoid mobility, distance shortening rate, geniohyoid muscle activity, activity time and activity speed were calculated, and the differences between the two groups were compared. Results: The observation group had lower activity range and speed of geniohyoid muscle, and longer activity time than the control group, with statistical difference (P<0.05). The range of motion,velocity and shortening rate of distance from mandible to hyoid in patients with dysphagia after stroke were lower
than those in the control group, and the activity time was longer than that in the control group (P<0.05).Conclusion: B/M mode ultrasound can quantitatively detect the dynamic parameters of hyoid and geniohyoid muscles, which is helpful to accurately analyze the degree of dysphagia in patients with dysphagia after stroke and provide quantitative indexes for clinical rehabilitation evaluation and treatment.
