ABSTRACT

Objective To explore the effects of videofluoroscopic swallowing study (VFSS) in the assessment of dysphagia in post-stroke patients. To study the representation and rehabilitative outcome of dysphagia following stroke. Methods Seventy post-stroke patients and 80 normal adults were assigned to study group and control group and underwent VFSS. Abnormal signs on VFSS were compared between 2 groups. Aspiration patients received swallowing therapy for 4 weeks followed by VFSS again. Abnormal signs on VFSS were compared with those of pre-treatment. Results Penetration/aspiration, oral retention and pharyngeal retention occurred respectively at a frequency of 5.0%, 13.4% and 25.3% in control group in mild status, 45.0%,46.5%, 48.9% in study group in moderate to severer status. 10 times of silent aspiration were seen, accounting for 24.4% of all aspiration. The frequency of severe penetration/ aspiration decreased after the treatment (P
