Biofeedback as an Adjunctive Treatment for Post-stroke Dysphagia

The aim of the study is to evaluate whether the effect of biofeedback treatment is more effective than a control treatment in the recovery of dysphagia.

This study will be a multicentric randomized, single-blind controlled study. The investigators intend to recruit 100 patients who have suffered a stroke and have dysphagia. Fifty patients will undergo training with bio-feedback (experimental group) and the other fifty patients will undergo standard training, using only verbal feedback rather than visual feedback (control group). Our hypothesis, based on the results obtained in some previous studies, is that in the control group the efficacy of the treatment will be lower in the absence of immediate visual feedback of strength, timing, coordination and efficacy of the swallowing act.
