On the basis of routine treatment and routine swallowing rehabilitation training, iTBS treatment was given to the representative area of mylohyoid cortex on the affected side and cTBS treatment was given to the representative area of mylohyoid cortex on the healthy side

On the basis of routine treatment and routine swallowing rehabilitation training, iTBS treatment was given to the representative area of mylohyoid cortex on the affected side and sham cTBS treatment was given to the representative area of mylohyoid cortex on the healthy side

On the basis of routine treatment and routine swallowing rehabilitation training, sham iTBS treatment was given to the representative area of mylohyoid cortex on the affected side and sham cTBS treatment was given to the representative area of mylohyoid cortex on the healthy side

The stimulation intensity of TBS was 80%RMT, with a total of 600 pulses, five times a week for two weeks. In the bilateral stimulation group, iTBS treatment was given to the representative area of mylohyoid cortex on the affected side and cTBS treatment was given to the representative area of mylohyoid cortex on the healthy side. In the unilateral stimulation group, iTBS treatment was given to the representative area of mylohyoid cortex on the affected side and sham cTBS treatment was given to the representative area of mylohyoid cortex on the healthy side. In the sham stimulation group, sham iTBS treatment was given to the representative area of mylohyoid cortex on the affected side and sham cTBS treatment was given to the representative area of mylohyoid cortex on the healthy side. When giving sham stimulation, put the coil vertically so that the coil is perpendicular to the patient's skull surface , it will not produce real therapeutic effect.

The Rosenbek Penetration-aspiration scale assesses the patient's swallowing function by assessing the severity of penetration and aspiration. The results of Rosenbek Penetration-aspiration scale are divided into 8 grades from 1 to 8, and the lower the score, the better the swallowing ability.

The Standardized Swallowing Assessment scale is divided into three parts: clinical examination, water test, and normal eating, and is used to evaluate the safety and effectiveness of swallowing. The highest score of Standardized Swallowing Assessment scale is 46, and the lowest score is 18. The lower the score, the better the swallowing function.

fNIRS is a brain function detection technology, which can indirectly reflect the brain neural activity by detecting the content of oxygenated and deoxygenated hemoglobin in the cerebral cortex in real time. In this study, fNIRS was used to assess brain region activation and network connectivity characteristics during swallowing tasks.
