研究目的:

旨在评估rTMS联合rPMS是否能更有效地改善PSD患者的吞咽功能以及探索其是否能通过促进脑功能重塑和调节吞咽相关神经通路,从而为临床康复提供新的治疗策略。  

Objectives of Study:

This study aims to evaluate whether combined rTMS and rPMS can more effectively improve swallowing function in patients with post-stroke dysphagia (PSD), and to explore whether it promotes brain functional remodeling and modulates swallowing-related neural pathways, thereby providing new therapeutic strategies for clinical rehabilitation.

组别:

rTMS + rPMS 刺激组

样本量:

18

Group:

rTMS + rPMS stimulation group

Sample size:

干预措施:

高频 rTMS 刺激:使用“8”字形线圈,刺激位点位于患侧 M1 区,频率:10Hz,强度:80%静息态运动阈值(以健侧拇短展肌静息运动阈值为参考),20 次丛内刺激,每丛爆发/刺激包含 20 个脉冲,每次脉冲持续2s,间歇 15s,共 1200 个脉冲,持续17分钟。每天 1 次,每周 6 次,疗程 12 天。 高频 rPMS 刺激:使用直径为3cm的定制柱形线圈,刺激点位于舌骨上肌群,频率、强度、脉冲总数等参数与rTMS相同。

干预措施代码:

Intervention:

High-frequency rTMS stimulation: Using a figure-of-8 coil, the stimulation site was located at the affected M1 area. Parameters: frequency 10 Hz, intensity 80% of the resting motor threshold (referenced to the resting motor threshold of the healthy abductor pollicis brevis muscle), 20 trains of stimuli, each burst/train containing 20 pulses, with each pulse lasting 2 s and an inter-train interval of 15 s, totaling 1200 pulses over 17 minutes. Administered once daily, 6 times per week, for a total treatment course of 12 days. High-frequency rPMS stimulation: Using a custom cylindrical coil with a diameter of 3 cm, the stimulation point was located at the suprahyoid muscle group. Parameters such as frequency, intensity, and total number of pulses were consistent with those of rTMS.

组别:

rTMS 伪刺激+ rPMS 真刺激组

样本量:

Group:

rTMS Sham + rPMS Active Group

Sample size:

干预措施:

rTMS 假刺激:使用“8”字形线圈,仪器设备、刺激参数、刺激部位均与 rTMS 真刺激组相同,但当定位完成后,进行磁刺激时线圈平面与脑部表面垂直,将无感生电流输出,不产生刺激。 高频 rPMS 刺激:使用直径为3cm的定制柱形线圈,刺激点位于舌骨上肌群,频率、强度、脉冲总数等参数与rTMS相同。

干预措施代码:

Intervention:

rTMS Sham Stimulation: A figure-of-8 coil was used. The equipment, stimulation parameters, and stimulation site were identical to those in the rTMS active stimulation group. However, after positioning was completed, during magnetic stimulation, the coil plane was placed perpendicular to the scalp surface. This orientation ensured that no induced current was output, resulting in no effective stimulation. High-frequency rPMS Stimulation: A custom cylindrical coil with a diameter of 3 cm was used. The stimulation point was located at the suprahyoid muscle group. Parameters such as frequency, intensity, and the total number of pulses were consistent with those used in rTMS.

This configuration ensured that no induced current was generated, resulting in no effective stimulation. rPMS Sham Stimulation: A custom coil was used. The equipment, stimulation parameters, and stimulation site were identical to those in the rPMS active stimulation group. However, after positioning was completed, during the delivery of stimulation, the coil plane was oriented perpendicular to the longitudinal axis of the body. This configuration ensured that no induced current was generated, resulting in no effective stimulation.

干预措施代码:

Intervention:

High-frequency rTMS stimulation: An "8"-shaped coil was used, with the stimulation site located at the contralateral M1 area. Parameters: frequency 10 Hz, intensity 80% of the resting motor threshold (referenced to the resting motor threshold of the healthy abductor pollicis brevis muscle). Each session consisted of 20 trains of stimuli, with each train containing 20 pulses. Pulse duration: 2 s, inter-train interval: 15 s, totaling 1200 pulses per session. Session duration: 17 minutes. Administered once daily, 6 sessions per week, over a 12-day treatment course. rPMS sham stimulation: A customized coil was used, with identical equipment, stimulation parameters, and stimulation site to the real rPMS group. However, after positioning, the coil plane was perpendicular to the body's longitudinal axis during stimulation, resulting in no induced current output and thus no effective stimulation.

随机方法(请说明由何人用什么方法产生随机序列):

随机分组方案由统计专业人员按分段方法产生,区组长度(Block Size)为8,4组试验(A/B/C/D组)分配模式为:ABCDDCBA、ACBDBDCA...,当受试者符合纳入以及排除标准时,由专人按照入组顺序确定相应分组,对受试者进行试验。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization scheme was generated by statistical professionals using a block randomization method, with a block size of 8. The allocation pattern for the four trial groups (A/B/C/D) was set as: ABCD DCBA, ACBD BDCA, etc. When a subject met both the inclusion and exclusion criteria, designated personnel assigned the corresponding group based on the order of enrollment and proceeded with the trial.

盲法:

单盲法:通过对受试者设盲,来控制和减少因受试者心理因素(如期望效应、安慰剂效应、紧张情绪等)所导致的偏差,从而更客观地评估干预措施的真实效果。

Blinding:

Single-blind method: By blinding the subjects, it controls for and reduces biases caused by participants' psychological factors (such as expectation effects, placebo effects, anxiety, etc.), thereby enabling a more objective evaluation of the true effectiveness of the intervention.
