DYSPHAGIA
Swallowing is a set of rapid, highly coordinated neuromuscular actions that begin with lip closure and terminate with upper esophageal sphincter closure after a bolus passes through [At present, there is no standard treatment plan for post-stroke dysphagia. With the increasing use of non-invasive brain stimulation (NIBS) technology, in addition to the sensory and motor training of peripheral swallowing muscles for the treatment of dysphagia, central regulation technology has become a hot topic in the field of swallowing rehabilitation. The NIBS, such as transcranial direct current stimulation (tDCS), can promote brain plasticity, which can improve the swallowing function of patients with post-stroke dysphagia [In our study, combined with conventional swallowing rehabilitation therapy, tDCS therapy was applied to patients with post-stroke dysphagia to observe the effect of the technique. Given the lack of literature on the long-term efficacy of tDCS in treating post-stroke dysphagia, we observed and recorded the swallowing function of patients at the 3-month follow-up. We aimed to explore a more effective and safer rehabilitation training program for post-stroke dysphagia.
