Stroke represents the most common etiology, with approximately 65% of acute stroke patients experiencing pharyngeal swallowing difficulties. Clinical manifestations of dysphagia vary widely in severity and may include residue, reflux, delayed swallowing initiation, aspiration, and cricopharyngeal muscle dysfunction. Due to its detrimental effects on nutrition, respiration, and psychosocial well-being, dysphagia significantly impairs patients' quality of life. Furthermore, the inability to swallow safely and efficiently can lead to serious complications such as aspiration pneumonia, malnutrition, and depression. The traditional swallowing rehabilitation treatment has limited effect in clinical practice, which makes it necessary to search for new effective swallowing methods.\n\nConventional swallowing rehabilitation often yields limited clinical benefits, highlighting the urgent need for more effective therapeutic strategies. Transcranial direct current stimulation (tDCS) is a non-invasive and safe neuromodulation technique that has shown promise in the field of neurorehabilitation. Its mechanisms extend beyond immediate cortical modulation and cerebral blood flow changes to include the regulation of synaptic plasticity, neurotransmitters such as glutamate and GABA, and excitability in remote subcortical regions. In recent years, tDCS has been increasingly applied to various neurological disorders, including post-stroke motor impairment, dysphagia, aphasia, depression, addiction, and spinal cord injury-related movement disorders. Currently, tDCS is being explored to elucidate its regulatory effects on cerebellar swallowing control, positioning it as a potential innovative treatment for neurogenic dysphagia.",[68],"Dysphagia After Stroke","NOT_YET_RECRUITING","2025-10-01",{"date":72,"type":73},"2025-10-08","ACTUAL",{"date":75,"type":62},"2025-12-01",{"date":77,"type":62},"2027-12-31",{"name":5,"class":6}]
