Abstract: Objective To investigate the factors related with swallowing function after stroke. Methods Stroke patients with dysphagia were reviewed, 296 cases with pseudobulbar paralysis, and 82 cases with bulbar paralysis. Swallowing function was evaluated with videofluoroscopic swallowing study (VFSS). The variable of age, sex, Body Mass Index (BMI), scores of National Institutes of Health Stroke Scale (NIHSS), Simplified Fug- Meyer Assessment (FMA) and modified Barthel Index (MBI), intubation, aspiration, length of hospitalization (LOH), and initiation of rehabilitation intervention were analyzed with Logistic regression. Results Age, NIHSS score, intubation, aspiration, initiation of rehabilitation intervention were the risk factors for poor outcome of swallowing function in all the patients, while the score of MBI was the protective factor for the pseudobulbar paralysis ones. Conclusion The younger the patients, the less the NIHSS score, no intubation, no aspiration, and the earlier the rehabilitation intervened, the more independent the pseudobulbar paralysis patients, the better swallowing function recovered.
