Abstract: Objective To explore the effects of videofluoroscopic swallowing study (VFSS) in the assessmentof penetration/aspiration in post-stroke patients, and study the frequency of penetration/aspirationfollowing stroke.Methods Total 70 post-stroke patients and 80 normal adults were assigned to study group andcontrol group respectively. VFSS was done during swallowing on them. Abnormal signs on VFSSwere compared between two groups. The frequency of penetration/aspiration and residue of oraland pharyngeal cavity were investigated.Results Aspiration wasn’t seen in control group. Penetration/aspiration were seen in swallowingall kinds of alimentary boluses. Most of them were moderate/severe penetration or aspiration. Silentaspiration was seen in 24.4% patients with aspiration. The frequency of moderate/severe pharyngealresidue was higher in severe penetration/aspiration group than in non-severe penetration/aspirationgroup (P <0.05).Conclusion Aspiration is common in convalescent patients with stroke in restoration stage.Aspiration can been seen in swallowing all kinds of alimentary boluses. VFSS can confirmpenetration/aspiration.
