Abstract:
Objective:To investigate the clinical value of ultrasound in evaluating pharyngeal dysphagia after stroke.Methods:Thirty stroke survivors with dysphagia formed the patient group, and 30 healthy persons formed the healthy group. All received pharyngeal ultrasound examinations by the same sonographer. The maximum distance from the hyoid bone to the mandible, the minimum distance, and the required time were measured or calculated. The hyoid bone′s motion, distance shortening rate, geniohyoid muscle activity, activity time, and activity speed were calculated. The differences in each value were compared, and the values were correlated with the videofluoroscopic swallowing study (VFSS) score using Spearman rank correlation. Receiver operating characteristics curves (ROC curves) were used to evaluate the value of hyoid bone and geniohyoid muscle activity for evaluating the severity of pharyngeal swallowing disorders after a stroke.Results:The average range of activity, activity time, and activity speed of the geniohyoid muscle in the patient group were all significantly different from the healthy group′s averages. The hyoid bone′s range of activity, activity time, activity speed, and the rate of shortening of its distance from the mandible were also significantly different, on average. The patients′ VFSS grades correlated strongly with the activity of the geniohyoid muscle, moderately with the geniohyoid muscle′s speed, and weakly with the duration of hyoid bone activity.Conclusion:The speed of geniohyoid muscle activity and hyoid bone activity time can be used to evaluate the severity of pharyngeal swallowing dysfunction after a stroke. Geniohyoid muscle activity is the best indicator.
