| Objective：To explore the value in the evaluation of dysphagia degree, B/M ultrasonography was used to measure the motion parameters of hyoid and geniohyoid muscles in stroke patients with pharynx dysphagia. Methods：Forty stroke patients were selected as the study subjects, all of whom were confirmed to have dysphagia in pharynx by swallowing angiography. Seven pharyngeal indicators in the Video Dysphagia Dysfunction Scale (VDS) were selected for evaluation, with the full score of 60. According to the results, the patients were divided into two groups: <30 score (mild group) and ≥30 score (severe group). Ultrasound was used to measure hyoid displacement, geniohyoid muscle movement distance and movement time during empty swallowing. The tube feeding conditions of the two groups were recorded. Results: Hyoid displacement and geniohyoid muscle movement distance in mild group were higher than those in severe group (P<0.05). There was no significant difference in the movement time of geniohyoid muscle between the two groups. Only few patients in the mild group needed to be fed, and all patients in the severe group needed to be fed, showing statistical difference between the two groups (P<0.05). Conclusion: Ultrasonography can quantitatively detect the kinematology of the hyoid displacement and geniohyoid muscle movement, which is helpful to analyze the degree of dysphagia in patients with pharyngeal dysphagia after stroke, and provide quantitative indicators for clinical rehabilitation treatment. |
