UNASSIGNED: The purpose of this study was to investigate swallowing kinematics and explore kinematic factors related with penetration- @entity1173 in @entity1 with post- @entity64 . Videofluoroscopic images of 68 @entity1 with post- @entity64 and 34 sex- and age-matched healthy controls swallowing a thin liquid were quantitatively analyzed using two-dimensional motion digitization. The measurements included the movement distances and velocities of the hyoid and larynx, and the maximal tilt angles and angular velocities of the @entity2582 . All velocity variables were significantly decreased in the @entity64 @entity1 compared to the controls. There was a significant difference in the maximal horizontal displacement of the larynx, but there were no significant differences in other displacements of the larynx, the maximal displacements of the hyoid bone, and the maximum tilt angle of the @entity2582 between the two groups. The maximal tilt angle of the @entity2582 was lower in the @entity1173 subgroup than in the no penetration/ @entity1173 and penetration subgroups as well as the controls. The maximal tilt angle from the y axis showed a dichotomous pattern at 90   of the angle, and all 11 @entity1 with an angle <90   showed either penetration or @entity1173 . In the ROC curve of the angle for prediction of @entity1173 , the area under the curve was 0.725 (95  % CI 0.557-0.892, P  =  0.008). This study suggested that sluggish rather than decreased hyolaryngeal movements during swallowing are a remarkable feature of post- @entity64 . The association of reduced epiglottic movement with the risk of @entity1173 in @entity1 with post- @entity64 was supported by the quantitative analysis.
