Abstract:
Objective To evaluate the effect of the modified balloon dilatation intervention on the pharyngeal constriction function of the brainstem stroke survivors with dysphagia using videofluoroscopy-based digital analysis.Methods Thirty brainstem stroke survivors with pharyngeal dysphagia were recruited and randomly divided into a treatment group and a control group,with 15 in each.The treatment group was treated with the modified balloon dilatation in addition to the routine treatment of 30min,respectively,once a daily,3 days a week,whiled a control group was treated with routine treatment of 30min twice a day,3 days a week.Before and after the treatment,the rate and duration of pharyngeal constriction were measured in both groups.Results After the treatment,the rate of pharyngeal constriction in the treatment group was (0.20 ± 0.030),(0.14 ± 0.05) and (0.15 ± 0.04) when swallowing thin liquid,thick liquid and pasty food,significantly better than before the treatment.The duration of the pharyngeal constriction was (990.34 ±96.14),(1010.47 ± 133.64) and (1180.10 ± 121.27) ms,respectively,also significantly better than before the treatment.In the control group,significant differences were also observed in the rate and duration of pharyngeal constriction before and after the treatment.Conclusions Digital analysis based on videofluoroscopy can be used to quantify swallowing function effectively,and the rate and duration of pharyngeal constriction can be used to evaluate the pharyngeal function before and after treatment.
