研究目的:

本研究旨在探究脑电(EEG)引导的个体化经颅交流电刺激(tACS)在实验性疼痛调控中的有效性及其潜在神经机制。通过采集静息态与疼痛态脑电信号,并结合个体结构磁共振成像(T1)进行源定位分析,本研究拟构建四种刺激策略,包括组靶点刺激、个体化单靶点刺激、个体化双靶点刺激和假刺激,并比较不同刺激策略在镇痛效果上的差异。 本研究以健康受试者为对象,采用辣椒素诱发实验性疼痛模型,在标准化条件下比较四种刺激策略对主观疼痛评分变化的影响,评价脑电引导的个体化刺激是否优于传统组水平靶点刺激,并进一步考察个体化双靶点刺激是否较个体化单靶点刺激具有更优的镇痛效果。同时,本研究将结合刺激前后脑电特征变化,分析疼痛相关脑区及脑网络活动的调节规律,探讨不同刺激策略发挥镇痛作用的可能神经机制。 本研究拟为建立安全、无创、精准、可推广的个体化镇痛神经调控方案提供实验依据,并为非药物镇痛的临床转化提供理论支持。  

Objectives of Study:

This study aims to investigate the analgesic efficacy and potential neural mechanisms of EEG-guided individualized transcranial alternating current stimulation (tACS) in the modulation of experimental pain. By collecting resting-state and pain-state EEG signals and combining them with individual structural MRI (T1) for source localization, the study will establish four stimulation strategies, including group-target stimulation, individualized single-target stimulation, individualized dual-target stimulation, and sham stimulation, and compare their analgesic effects. Healthy participants will undergo a capsaicin-induced experimental pain paradigm under standardized conditions. The study will compare the effects of the four stimulation strategies on subjective pain ratings, evaluate whether EEG-guided individualized stimulation is superior to conventional group-level targeting, and further examine whether individualized dual-target stimulation provides greater analgesic benefit than individualized single-target stimulation. In addition, changes in EEG features before and after stimulation will be analyzed to characterize the modulation of pain-related brain regions and brain networks, thereby exploring the neural mechanisms underlying the analgesic effects of different stimulation strategies. This study is expected to provide experimental evidence for the development of a safe, non-invasive, precise, and clinically translatable individualized neuromodulation approach for pain relief, and to offer theoretical support for the clinical translation of non-pharmacological analgesia.

Intervention:

The study includes four stimulation conditions: group-target stimulation, individualized single-target stimulation, individualized dual-target stimulation, and sham stimulation. In the active tACS conditions, EEG-guided transcranial alternating current stimulation will be delivered at a frequency of 40 Hz, with a current intensity of 1.5 mA for 30 minutes. For group-target and individualized single-target stimulation, the stimulation target is the right sensorimotor cortex. For individualized dual-target stimulation, the stimulation targets are the right sensorimotor cortex and the left dorsolateral prefrontal cortex.

随机方法(请说明由何人用什么方法产生随机序列):

随机序列由不参与受试者招募、刺激实施及结局评估的独立研究人员生成。采用计算机随机数字表法/随机化软件(如 SPSS 或 Excel 随机函数)生成四种刺激条件(组靶点刺激、个体化单靶点刺激、个体化双靶点刺激、假刺激)的施加顺序,并为每位受试者分配唯一的随机序列编号。随机结果由专人保存,在受试者完成入组后按预设序列实施相应刺激。研究主要结局评估与数据分析阶段尽量在盲态下进行,以减少偏倚

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

The randomization sequence will be generated by an independent researcher who is not involved in participant recruitment, stimulation delivery, or outcome assessment. A computer-generated randomization method (e.g., random number table, SPSS, or Excel random function) will be used to determine the order of the four stimulation conditions (group-target stimulation, individualized single-target stimulation, individualized dual-target stimulation, and sham stimulation) for each participant. Each participant will be assigned a unique randomization code. The allocation list will be kept by designated personnel, and the corresponding stimulation condition will be implemented according to the predefined sequence after enrollment. Outcome assessment and data analysis will be conducted under blinded conditions as far as possible to minimize bias.

是否公开试验完成后的统计结果:

公开/Public

盲法:

本研究采用受试者盲法和结局评估者盲法。受试者不知道每次实验所接受的具体刺激条件;结局评估及数据分析人员不知道随机分配顺序及条件编码。刺激实施人员因需要根据随机序列设置刺激参数,原则上不参与主要结局评估与统计分析。

Blinding:

This study will use participant blinding and outcome assessor blinding. Participants will be unaware of the specific stimulation condition administered at each visit. Outcome assessors and data analysts will be blinded to the randomization order and condition codes. The personnel delivering stimulation will not participate in the primary outcome assessment or statistical analysis.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用标准化的数据采集与管理流程,包括病例记录表(Case Report Form, CRF)和电子数据采集/管理系统(Electronic Data Capture, EDC)两部分。CRF用于记录受试者基本人口学信息、纳入与排除标准、随机分配顺序、刺激条件、疼痛评分、量表结果、不良事件及实验完成情况等。脑电数据、MRI影像数据、刺激参数及其他原始实验数据统一由加密电子数据库进行存储和管理。所有受试者均采用唯一研究编码进行去标识化处理,身份信息与研究数据分开保存,仅限授权研究人员访问。数据录入后将进行核查、逻辑校验和定期备份,以保证数据的真实性、完整性和安全性。研究结束后,数据将按相关规范长期保存,并仅用于经批准的科研目的。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

A standardized data collection and management procedure will be used in this study, including a Case Report Form (CRF) and an Electronic Data Capture/management system (EDC). The CRF will be used to record demographic information, eligibility criteria, randomization order, stimulation conditions, pain ratings, questionnaire results, adverse events, and study completion status. Raw EEG data, MRI data, stimulation parameters, and other experimental data will be stored and managed in a secure encrypted electronic database. All participants will be assigned unique study codes and all data will be de-identified. Personal identifiers will be stored separately from research data, and access will be restricted to authorized study personnel only. Data entry will undergo verification, logic checks, and regular backup to ensure accuracy, completeness, and security. After study completion, the data will be retained in accordance with relevant regulations and used only for approved research purposes.
