About this trial

The goal of this clinical trial is to learn whether individualized transcranial temporal interference stimulation can improve swallowing in adults with swallowing difficulties after an ischemic stroke. It will also evaluate the safety and tolerability of this stimulation. The main questions it aims to answer are:

* Does active temporal interference stimulation combined with swallowing rehabilitation improve swallowing safety more than sham stimulation combined with the same rehabilitation? * What side effects or medical problems occur during and after the stimulation?

Researchers will compare active stimulation with sham stimulation, which uses the same equipment but does not deliver sustained therapeutic stimulation.

Participants will:

* Receive active or sham stimulation for 30 minutes per session, 5 days per week for 2 weeks * Receive the same task-specific swallowing rehabilitation after each stimulation session * Undergo swallowing assessments, brain imaging, and neurophysiological testing * Attend follow-up assessments 4 and 12 weeks after treatment

Eligibility criteria

Qualifiers

Age 18 to 80 years

First-ever unilateral supratentorial ischemic stroke confirmed by computed tomography or magnetic resonance imaging

Stroke onset 14 to 90 days before randomization

Oropharyngeal dysphagia confirmed by videofluoroscopic swallowing study, with a worst Penetration-Aspiration Scale score of 3 to 7 during prespecified standardized bolus trials

Disqualifiers

Brainstem or primary cerebellar stroke, bilateral cerebral infarction, previous symptomatic stroke, intracranial hemorrhage, or progressive neurological disease

Pre-stroke dysphagia, structural oropharyngeal disease, previous treatment for head and neck cancer, or another condition that independently explains dysphagia

Tracheostomy, current mechanical ventilation, uncontrolled pneumonia, severe hypoxemia, or hemodynamic instability

History of epilepsy, seizure after the index stroke, unexplained loss of consciousness, or current use of medication considered to confer an unacceptable seizure risk
