Brief Summary

The purpose of this study was to observe the effect of Theta burst transcranial magnetic stimulation (TBS) on swallowing function in patients with dysphagia after stroke (PSD). Functional near- infrared spectroscopy (fNIRS) was used to detect the changes in activation and functional connectivity of related brain regions in PSD patients treated with intermittent TBS（iTBS）stimulation on the affected side and consistent TBS（cTBS） stimulation on the healthy side. To investigate the effects of TBS on swallowing related cortical excitability in stroke patients with dysphagia and explore its possible mechanism, and provide theoretical basis for the treatment of PSD patients.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

Bilateral stimulation group

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

Group Type: EXPERIMENTAL

Theta burst transcranial magnetic stimulation

Intervention Type: DEVICE

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.

Unilateral stimulation group

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
