In plain words

What the trial is, and whether it could suit you

Post-stroke dysphagia is a common complication that negatively affects nutritional status, quality of life, and morbidity. Conventional swallowing rehabilitation, including oropharyngeal exercises and neuromuscular electrical stimulation (NMES), is widely used to improve swallowing function. This randomized controlled clinical study aims to investigate the effectiveness of visual biofeedback-assisted oropharyngeal exercises combined with NMES in patients with post-stroke dysphagia. Participants will be randomly assigned to either a visual biofeedback-assisted exercise group or a conventional exercise group, with both groups receiving NMES. Treatment will be administered five days per week for four weeks. Changes in swallowing function, suprahyoid muscle activity assessed by surface electromyography, and muscle stiffness evaluated by shear wave elastography will be analyzed to determine t
