干预措施:

HD-tDCS干预:使用Starstim 8(Neuroelectrics, Spain)设备,对左侧背外侧前额叶(L-DLPFC,电极位置F3)施加HD-tDCS刺激。参考既往研究,阳极置于F3,阴极置于FC1、AF3、F7、FC5,电流强度2mA,持续时间30分钟,共进行10次干预。 健康教育:所有受试者将接受标准化健康教育,包括腰痛科普、运动指导、生活方式建议等。干预前研究人员进行15分钟一对一指导,并提供图文手册供日常练习。

干预措施代码:

Intervention:

HD-tDCS Intervention: HD-tDCS will be applied using the Starstim 8 device (Neuroelectrics, Spain) to the left dorsolateral prefrontal cortex (L-DLPFC, electrode position F3). Based on previous studies, the anode will be placed at F3, and the cathodes will be placed at FC1, AF3, F7, and FC5. The current intensity will be set to 2mA, with a duration of 30 minutes for each session. A total of 10 interventions will be conducted. Health Education: All participants will receive standardized health education, which will include information on low back pain, exercise guidance, and lifestyle recommendations. Prior to the intervention, researchers will provide 15 minutes of one-on-one instruction and offer a pictorial manual for daily practice.

干预措施:

假刺激干预:接受模拟真刺激的假刺激过程,前30秒升至1mA,15秒内迅速降至0mA,最后30秒升至1mA,再15秒内迅速降至0mA,确保安慰剂效应。 健康教育:内容、实施方式与实验组完全一致。

干预措施代码:

Intervention:

Sham Stimulation Intervention: Participants will undergo a sham stimulation process, which simulates the real stimulation. The current will rise to 1mA within the first 30 seconds, then quickly drop to 0mA within 15 seconds. The current will then rise again to 1mA during the last 30 seconds and drop quickly to 0mA within the following 15 seconds, ensuring the placebo effect. Health Education: The content and implementation method will be identical to the experimental group.

随机方法(请说明由何人用什么方法产生随机序列):

采用计算机生成的随机数表进行受试者分配,按照1:1的比例随机分配至以下两组:实验组(HD-tDCS 组):接受真实的HD-tDCS刺激;对照组(假刺激组):接受安慰剂刺激。随机分配过程由独立研究人员执行,该人员不参与数据收集和分析,以确保研究人员对受试者分配情况不产生干扰。

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

Participants will be assigned using a computer-generated random number table, with a 1:1 ratio for the following two groups: Experimental Group (HD-tDCS Group): Receives real HD-tDCS stimulation. Control Group (Sham Stimulation Group): Receives placebo stimulation. The randomization process will be carried out by an independent researcher who is not involved in data collection or analysis, ensuring that the researchers do not interfere with the participant assignment.

盲法:

本研究采用双盲设计,受试者不会被告知自己属于实验组还是对照组。对照组采用假刺激方法(仅在前30秒和后30秒提供1mA电流模拟真实刺激感),以减少安慰剂效应的影响。负责数据收集、疼痛评分、抑郁评估和EEG记录的研究人员对受试者的组别保持盲态,避免主观偏倚影响研究结果。参与干预实施的技术人员仅按照系统生成的刺激方案执行实验,而不知晓受试者具体分组情况。HD-tDCS设备由预设模式控制,实验过程中无法手动调整受试者的刺激模式,确保技术人员无法区分实验组和对照组。研究数据将在实验结束后由独立统计分析师处理,并采用代码编号(如Group A/B)隐藏受试者组别,直到数据分析完成后才解盲,以确保分析过程的客观性。

Blinding:

This study will use a double-blind design, meaning participants will not be informed of whether they belong to the experimental group or the control group. The control group will receive sham stimulation (with 1mA current provided only during the first and last 30 seconds to simulate the real stimulation experience), to minimize the placebo effect. The researchers responsible for data collection, pain assessments, depression evaluations, and EEG recordings will remain blinded to the participants' group allocation to avoid subjective bias in the study results. The technicians involved in implementing the intervention will only follow the system-generated stimulation protocol without knowing the specific group assignments. The HD-tDCS device will be controlled by a preset mode, and it will not be possible to manually adjust the stimulation protocol during the experiment, ensuring that the technicians cannot distinguish between the experimental and control groups. The study data will be processed by an independent statistician after the experiment is completed, with participant groups coded (e.g., Group A/B) to conceal group allocation. The unblinding will occur only after the data analysis is completed to ensure objectivity in the analysis process.

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:

结局指标测量时会有两名工作人员在场,一名负责记录,一名负责指导受试者进行测量。这两名工作人员均应有相关评价指标测试经验且受过项目组统一培训,此外,这两名工作人员应不清楚受试者分组情况;本研究所使用的研究工具均为同类研究中广泛应用的工具,信、效度良好,具体内容可见病例报告表(CRF);记录数据应当场记录在CRF上,并同时签上工作人员签名及日期。若需要更改,需要留下更改痕迹并署名及日期。 为提高受试者参与性和完成随访率,研究开始之前做好受试者教育,强调按照要求完成研究的意义和重要性,鼓励受试者按照要求完成研究; 受试者所有评估数据都记录在每个人的病例手册中,并以研究编号数字而非姓名加以标识。研究数据将不会透露给研究小组以外的成员,同时保存在有锁的档案柜中仅供研究人员查阅。 电子采集和管理系统EDC使用医渡云数据库(https://research.yiducloud.com.cn)进行同步管理。

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

Two staff members will be present when the outcome measures are taken, one to record and one to guide the subjects to take the measurements. These two staff members should have relevant experience in evaluation and have received unified training from the program team. In addition, these two staff members should not know the grouping. The research tools used in this study are widely used in similar studies, with good reliability and validity, and the specific contents can be seen in the case report form (CRF). The recorded data shall be recorded on the CRF and signed and dated by the staff member. If CRF needs a change, it needs to leave a change track, sign, and date. In order to improve participants' participation and follow-up completion rate, subjects will be educated before the start of the study, emphasize the significance and importance of completing the study, and encourage participants to complete the study as required. All assessment data for subjects was recorded in each subject's CRF and identified by study number rather than names or any other ID information. The study data will not be disclosed to members outside the research team and will be kept in a locked filing cabinet for researchers' access only.
