The Changes of Masticatory / Swallowing Functions and Oropharyngeal Muscle Mass on Sonography After Comprehensive Swallowing Training and Tongue - Pressure Resistance Training in Stroke Patients With Dysphagia

The aims of this study are: 1. Comparing the ultrasound imaging performance of swallowing and chewing function, tongue pressure and oropharyngeal muscle thickness in stroke patients with different levels of swallowing function 2. To explore the changes in clinical mastication and swallowing functions, tongue pressure and oropharyngeal muscle thickness in patients with dysphagia and stroke after swallowing treatment and neuromuscular electrical stimulation training. 3. To explore the correlation between clinical mastication and swallowing functions, tongue pressure, oropharyngeal muscle thickness and ultrasound imaging results in patients with dysphagia and stroke.
