Effectiveness of an mHealth Intervention, Based on Rehabilitation and a Personalised Nutrition Plan, in the Recovery and Improvement of Dysphagia in Patients Diagnosed With Stroke

The goal of this clinical trial is to evaluate the efficacy of an mHealth intervention as a complement to usual clinical practice for the improvement and recovery of dysphagia in patients who have suffered a stroke. The main question it aims to answer is: \- Does the mHealth intervention improve the recovery of dysphagia in post-stroke patients compared to usual care alone? Researchers will compare patients receiving the mHealth intervention plus usual care to see if the combined approach leads to better dysphagia outcomes, reduced negative consequences (e.g., malnutrition, pneumonia), and improved quality of life compared to usual care alone. Participants will be recruited and: * Receive a diagnosis and usual care for post-stroke dysphagia. * Be assigned to either the mHealth intervention group (using a smartphone/tablet app for information and follow-up) or the control group (usual care only). * Be followed up to assess dysphagia recovery, reduction in negative outcomes (like aspiration pneumonia, dehydration), and changes in quality of life.
