Abstract:
Objective:To compare with video-fluoroscopic swallowing function test(VFSS),so as to evaluate the application value of ultrasonography in the test of dysphagia after stroke.Methods:A total of seventy-two patients with dysphagia after stroke who admitted to The Second Affiliated Hospital of Hainan Medical University from January 2022 to July 2023 were selected as cases group,and a total of 45 healthy aged with normal swallowing function were selected as healthy control group at the same time.All of them underwent video X-ray fluoroscopic examination of swallowing function and quantitative assessment of ultrasound.Quantitative assessment of ultrasound was performed by twice to compare the internal consistency of ultrasound test.Meanwhile,the correlation between ultrasound and VFSS results was tested to verify the validity of ultrasound quantitative assessment.The VFSS was used as gold standard to analyze the sensitivity and specificity of ultrasound assessment.The differences of abnormal grade of Geniohyoid muscle;movement time,movement distance and the change of tongue muscle thickness of semi quantitative description of ultrasound between two groups were compared.Results:The intra group correlation coefficient(ICC),movement time,movement distance and movement speed of grade description of muscle abnormalities of cases group were respectively 0.90,(1.743±0.235)s,(6.323±0.823)mm and(3.826±0.778)mm/s,which intra reliabilities were high correlation(ICC=0.90,0.82,0.87,0.85,P＜0.01),which inter reliabilities of these indicators were high correlation(ICC=0.86,0.85,0.88,0.87,P＜0.01),respectively.The positive results of ultrasound test highly correlated with the results of VFSS examination(r=0.91,P＜0.01).The movement distance,the average movement speed and the changes of the thickness of tongue muscle in patients of cases group were significantly smaller than those of healthy control group,but the movement time was larger than that of healthy control group(t=9.03,30.49,-7.02,22.69,P＜0.05),respectively.The results of the ultrasound on the muscles of all patients in cases group existed abnormality.Conclusion:Ultrasound technique can quantitatively assess dysphagia after stroke.Compared with VFSS technique,ultrasonography can measure and determine the related data of the movement of swallowing muscle,and dynamically record movement parameters of geniohyoid muscle and the changes of the thickness of tongue muscle.At the same time,it can detect the grade of muscle abnormalities of patients with dysphagia,which will contribute to further explore the potential pathological mechanism about muscle,and promote the healthy management for patients with dysphagia.
