Effect of a Cooling Sensation Flavor on the Swallow Response in

Status Recruiting

Clinical Trial Summary

Current oropharyngeal dysphagia (OD) treatment in older patients is based on compensatory strategies (fluid thickening and texture modified diets) that improve swallow safety but do not improve the swallowing function. One of these strategies is thickening products, which are used to reduce pharyngeal bolus velocity by increasing viscosity of fluids. There are several studies demonstrating the therapeutic effect of thickeners in reducing the prevalence of penetrations and aspirations, and their use has been correlated with reduced prevalence of respiratory infections, aspiration pneumonia and hospital readmissions. In recent years, new neurorehabilitation treatment strategies for OD have been developed such as peripheral (electrical or chemical stimulation) or central stimulation (transcranial direct current stimulation or repetitive transcranial magnetic stimulation). The investigators suggest that new generation treatments for OD have to combine thickened fluids and about peripheral stimulation using transient receptor potential (TRP) channels agonists. The aim of this study is to evaluate the therapeutic effect of a cooling sensation (CS) flavor in a pre-thickened oral nutritional supplement (ONS) drink on the biomechanical mechanism of the swallow response in chronic post-stroke patients with OD. The investigators designed a randomized, crossover, interventional and open-label clinical study. The study includes 2 groups: 1) n=25: 1st visit: stimulation with Control, 2nd visit: stimulation with CS; and 2) n=25: 1st visit: stimulation with CS, 2nd visit: stimulation with Control. Each patient will attend a total of 2 visits, with a washing period of at least 7 days between visits. The procedures to be performed during each visit are: clinical assessment of swallowing with V-VST, spontaneous swallowing frequency measurement using electromyography, and collection of a sample of saliva using a Salivette®.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
