The effects of tongue pressure resistance feedback training on post-stroke dysphagia / 中华物理医学与康复杂志

ABSTRACT

Objective:To explore the clinical utility of tongue pressure resistance feedback training in the treatment of post-stroke dysphagia.Methods:Twenty stroke survivors with dysphagia were randomly divided into an experimental group and a control group. Both groups were given conventional swallowing rehabilitation training, while the experimental group was additionally provided with tongue pressure resistance feedback training. Before and after the treatment, MBSImp analysis and the Rosenbek penetration aspiration scale were used to quantify the control of the tongue, food delivery, oral residue, laryngeal elevation, hyoid bone movement, epiglottis turnover, larynx closure, vestibular larynx closure, pharyngal peristalsis and contraction, opening of the upper esophageal sphincter UES, contraction of the base of the tongue, pharyngeal residue and aspiration.Results:No significant differences were observed between the two groups before the intervention. Afterward the average pharyngeal period and aspiration score of the experimental group had decreased significantly compared with the control group′s values.Conclusions:Tongue pressure resistance feedback training is effective in improving pharyngeal swallowing and reducing the risk of aspiration after swallowing.
