Background: Previous studies have found that high-frequency repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere could improve swallowing function, but whether intermittent theta burst stimulation (iTBS), which has similar excitatory effect and higher efficiency, can also improve swallowing function for dysphagia after stroke remains unclear. Objective: This trial aimed to explore the efficacy and safety of bilateral cerebellar transcranial magnetic stimulation with iTBS for dysphagia after stroke. Methods: Seventy patients with dysphagia after stroke were divided into 2 treatment groups: true bilateral cerebellar iTBS and sham bilateral cerebellar iTBS. The true iTBS group underwent ten 100% resting motor threshold (RMT) iTBS sessions for 2 weeks. In the sham iTBS group, the parameters were the same except that the figure-eight coil was perpendicular to the skull. Both groups received traditional swallowing rehabilitation treatment 5 times a week for 2 weeks. Swallowing function was assessed with the Fiberoptic Endoscopic Dysphagia Severity Scale (FEDSS), Penetration/Aspiration Scale (PAS), Standardized Swallowing Assessment (SSA), and Functional Oral Intake Scale (FOIS) at baseline, 2 weeks after the intervention, and at 4 weeks of follow-up. Results: There were significant time and group interaction effects in both multi-factorial adjusted and unadjusted FEDSS, PAS, SSA, and FOIS score ( P < .001). In the pairwise comparison of the swallowing...
