研究目的:

1.采用随机对照临床试验,考察作用于初级运动皮层的经颅电刺激(经颅直流电刺激(tDCS),叠加直流偏置的经颅随机噪声刺激(tRNS+DC-offset)对慢性疼痛患者的镇痛效果。 2.结合心理问卷、疼痛心理物理测量、静息态功能连接等多维度指标探究tDCS和tRNS+DC-offset的作用机制。  

Objectives of Study:

1.A randomized controlled clinical trial was conducted to investigate the analgesic effects of transcranial electrical stimulation targeting the primary motor cortex—specifically transcranial direct current stimulation (tDCS) and transcranial random noise stimulation with a DC offset (tRNS+DC-offset)—in patients with chronic pain. 2.Multidimensional indicators, including psychological questionnaires, psychophysical measurements of pain, and resting-state functional connectivity, were combined to explore the mechanisms of action of tDCS and tRNS+DC-offset.

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:

1. 数据采集 使用病例记录表采集患者的信息,包括人口学变量,临床症状,疼痛敏感性,情绪功能,生活质量等的评估;使用功能磁共振设备采集患者的脑静息态数据; 2. 数据管理 基于病例记录表采集的患者信息,包括人口学变量,临床症状,疼痛敏感性,情绪功能,生活质量评估结果将在收集后的一天内以扫描文档的方式上传至加密网盘,并且纸质文档将根据患者编号分装到单独的档案袋中;患者的脑静息态数据在采集一天内以相关数据文件的格式上传至加密网盘,并且在加密硬盘中进行备份。

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

1) Data Collection Patient information including assessment of demographic variables, clinical symptoms, pain sensitivity, emotional functioning, and quality of life will be collected using a case record form; patient resting state data will be collected using a functional magnetic resonance device; 2) Data Management Patient information based on the case record form including assessment of demographic variables, clinical symptoms, pain sensitivity, emotional functioning, and quality of life will be uploaded as a scanned document to an encrypted web drive within one day of collection, and paper documents will be separated into separate archive bags according to patient number; patient resting state data will be collected in a separate file within one day of collection. uploaded as scanned documents to an encrypted web drive within one day of collection and the paper documents will be separated into individual file bags based on patient number; patient's cerebral resting state data will be uploaded to an encrypted web drive in the format of the relevant data file within one day of collection and backed up on an encrypted hard drive.
