研究目的:

本研究旨在通过多模态评估手段,探讨tDCS刺激右侧初级体感皮层对急性缺血性脑卒中患者咳嗽反射中枢通路的调控作用。 主要目的:验证连续5天RS1区阳极tDCS干预能否有效降低患者对柠檬酸刺激的咳嗽反射阈值(LogC2/LogC5),重建有效的气道防御机制,并探索其对降低住院期间卒中相关性肺炎发生率的临床价值。 次要目的:利用床旁高密度脑电与功能连接分析技术,探究连续RS1区阳极tDCS干预对皮层神经电生理活动的调控效应,旨在阐明连续干预对受损“感觉-认知”脑网络的累积重塑与长时程神经可塑性改变。  

Objectives of Study:

The aim of this study is to investigate the regulatory effect of tDCS stimulation of the right primary somatosensory cortex on the central pathway of cough reflex in patients with acute ischemic stroke by multimodal evaluation. Primary objectives: To verify whether andic tDCS intervention in RS1 region for 5 consecutive days could effectively reduce the cough reflex threshold to citric acid stimulation (LogC2/LogC5), reestablish an effective airway defense mechanism, and explore its clinical value in reducing the incidence of stroked associated pneumonia during hospitalization. Secondary objectives: Using bedside high-density electroencephalography (EEG) and functional connectivity analysis techniques, we investigated the regulatory effect of continuous anodal tDCS intervention on cortical neurophysiological activities in RS1 region, in order to clarify the cumulative remodeling and long-term neuroplasticity changes of the impaired sensory-cognitive brain network after continuous intervention.

Group:

Active tDCS group

Sample size:

干预措施:

在常规康复基础上,受试者接受右侧初级体感皮层(RS1)阳极经颅直流电刺激(tDCS)。刺激电流强度设置为2.0mA,单次刺激时间为20分钟,共接受连续5次干预。

干预措施代码:

Intervention:

On the basis of conventional rehabilitation, the subjects receive anodal transcranial direct current stimulation (tDCS) over the right primary somatosensory cortex (RS1). The stimulation current intensity is set to 2.0 mA for 20 minutes per session, for a total of 5 consecutive sessions.

组别:

假刺激组

样本量:

30

Group:

Sham tDCS group

Sample size:

干预措施:

在常规康复基础上,受试者接受右侧初级体感皮层(RS1)假tDCS刺激。电极配置和持续时间(20分钟)与真刺激组相同,但刺激器仅在初始30秒电流强度渐增,随后30秒电流渐弱至0,其余时间不通电,共接受连续5次干预。

干预措施代码:

Intervention:

On the basis of conventional rehabilitation, the subjects receive sham tDCS over the right primary somatosensory cortex (RS1). The electrode configuration and duration (20 minutes) are identical to the active group, but the stimulator only delivers a ramp-up current for the initial 30 seconds and a ramp-down current for the subsequent 30 seconds, remaining off for the rest of the time, for a total of 5 consecutive sessions.

盲法:

本研究采用三盲设计(受试者盲、评估者盲、数据分析盲)。 1. 受试者盲:假刺激组采用与真刺激组相同的电极配置,仪器仅在起始30秒内输出微电流以模拟头皮感觉,随后断电,以保证受试者无法区分真假刺激。 2. 评估者盲:负责数据采集与疗效评估的人员独立于干预操作者,错峰入病房,严格实施信息隔离。 3. 数据分析盲:脑电预处理及统计分析由第三方人员在数据揭盲前独立完成。

Blinding:

The study used a triple-blind design (subject blind, evaluator blind, and data analysis blind). 1. Subject blind: The sham stimulation group used the same electrode configuration as the real stimulation group. The instrument only output microcurrent in the first 30 seconds to simulate scalp sensation, and then power off to ensure that the subjects could not distinguish the real and false stimuli. 2. Assessor blindness: the personnel responsible for data collection and efficacy evaluation were independent of the intervention operators, and were admitted to the ward at different peak times to strictly implement information isolation. 3. Blinding of data analysis: EEG preprocessing and statistical analysis were completed independently by a third party before unblinding of the data.
