Stroke Clinical Trial - Taste Stimulation for Post-stroke Dysphagia

Status Recruiting

Clinical Trial Summary

The goal of this clinical study is to compare the effect of favourate taste stimulation of oral cavity and tounge, with sour and traditional single thermal stimulation in post-stroke patients with dysphagia. The main questions it aims to answer are: 1. Whether favourate taste stimulation of oral and tounge is better than traditional thermal stimulation in improving swallowing function of patients with dysphagia. 2. It has been reported that taste of sour stimulation can increase the frequency of swallowing. In this study, we want to know which is better for improving swallowing function between favourate taste stimulation and sour taste stimulation. 3. Functional near-infrared spectroscopy (fNIRS) will be applied in this study to understand the neural mechanism of taste stimulation in improving swallowing function. Participants screened as post-stroke dysphagia will accept swallowing evaluation and fNIRS test before and after treatment. The treatment include taste stimulation and traditional swallowing training. Researchers will compare favourate taste stimulation with sour-taste stimulation and single thermal stimulation to see if the swallowing function improved faster and better in favourate taste stimulation group.

Clinical Trial Description

Taste perception can help to initiate swallow. Different taste has different impact on swallowing function. Patients with post-stroke dysphagia always have taste impairment and initiation delay of swallowing. In this study, patients with dysphagia after stroke will be recruited and treated with favourate taste stimulation or sour taste stimulation or non-taste stimulation for 2 weeks. Traditional swallowing rehabilitation will be applied base on the status of patients. Before and after the treatment, participants completed swallowing assessment, including quantitative measurement of hyoid displacement, functional oral intake scale (FOIS), dysphagia severity rating scale (DSRS), and standardized swallowing assessment (SSA). In order to understand the effect of taste stimulation on brain network, fNIRS will be conducted.The participants have to conduct these examination three to four weeks after the treatment to undertand the long-time effect of taste stimulation. ;

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.
