研究目的:

1.主要目的:评估真刺激间歇性θ爆发刺激(iTBS)+认知策略训练(CST)与假刺激iTBS+CST相比,在基线、干预后及随访时点对以下结局的疗效与持续性影响:(1)饮食/食物选择决策行为;(2)任务诱发的前额叶血流动力学反应〔功能近红外光谱(fNIRS)氧合血红蛋白(HbO)〕,重点关注左背外侧前额叶(l-dlPFC)与左眶额皮层(l-OFC);(3)体重相关结局(体质指数BMI)。 2.机制目的:检验预先设定的神经—行为通路假设:iTBS诱导的l-dlPFC招募/激活变化有助于提升饮食自我控制,并进一步促进BMI下降。  

Objectives of Study:

1.Primary objective. To evaluate the efficacy and durability of real iTBS + CST versus sham iTBS + CST on (1) dietary decision-making behavior, (2) task-evoked prefrontal hemodynamic responses (fNIRS HbO) in l-dlPFC and l-OFC, (3) weight-related outcomes (BMI) across baseline, post-intervention, and follow-up assessments. 2.Mechanistic objective. To test a prespecified neurobehavioral pathway in which iTBS-induced changes in l-dlPFC recruitment contribute to improved dietary self-control and subsequent BMI reduction.

Group:

Sample size:

干预措施:

采用真实间歇性θ爆发刺激(iTBS)作用于左背外侧前额叶(l-dlPFC;10–20 EEG系统 F3 位点),使用 Magstim Rapid2 刺激器及 70 mm “8”字形线圈。刺激强度设定为静息运动阈值(RMT)的 80%(RMT 以右侧拇短展肌 APB 的运动反应确定)。iTBS 参数为:每个爆发(burst)包含 3 个脉冲(50 Hz),以 5 Hz 重复;刺激列(train)持续 2 s,共 20 个刺激列;刺激列间隔(inter-train interval)为 8 s;总脉冲数 600,总刺激时长 192 s。干预频次与周期为每周 2 次,连续 4 周(共 8 次)。每次 iTBS 结束后,被试立即完成约 15 分钟的认知策略训练(CST)模块:包含 50 个随机试次(25 张高热量与 25 张低热量食物图片),并按照标准化的认知框架指令完成相应评分。

干预措施代码:

Intervention:

Real intermittent theta-burst stimulation (iTBS) over the left dorsolateral prefrontal cortex (l-dlPFC; F3, 10–20 EEG system) using a Magstim Rapid2 stimulator with a 70-mm figure-of-eight coil. Stimulation intensity: 80% resting motor threshold (RMT; determined from right APB). iTBS pattern: bursts of 3 pulses at 50 Hz repeated at 5 Hz; 2-s trains; 20 trains; inter-train interval 8 s; total 600 pulses; total duration 192 s. Schedule: 2 sessions/week for 4 weeks (8 sessions total). Immediately after each iTBS session, participants complete a ~15-min Cognitive Strategy Training (CST) module consisting of 50 randomized trials (25 high-calorie and 25 low-calorie food images) with standardized cognitive framing instructions and ratings (craving and willingness-to-pay).

Intervention code:

组别:

假刺激iTBS联合认知策略训练组

样本量:

40

Group:

sham iTBS + CST group

Sample size:

干预措施:

假刺激过程在发次数、刺激声音、被试体位与研究人员互动等方面均模拟真实 iTBS 程序;同时通过将线圈相对头皮表面旋转 90° 来最大程度降低有效皮层刺激。干预频次与周期为每周 2 次,连续 4 周(共 8 次)。每次假刺激 iTBS 结束后,被试立即完成与真实组相同的约 15 分钟 CST 模块(共 50 个随机试次;包含 25 张高热量与 25 张低热量食物图片),其指令与评分流程与真实组完全一致。

干预措施代码:

Intervention:

Sham iTBS combined with Cognitive Strategy Training (CST). Sham stimulation mimics the active iTBS procedure in session timing, number of trains/bursts, stimulation sound, participant positioning, and staff interaction, while minimizing effective cortical stimulation by rotating the coil by 90° relative to the scalp surface. Schedule: 2 sessions/week for 4 weeks (8 sessions total). Immediately after each sham iTBS session, participants complete the same ~15-min CST module (50 randomized trials; 25 high-calorie and 25 low-calorie food images) with identical instructions and rating procedures as the real group.

随机方法(请说明由何人用什么方法产生随机序列):

随机分组将采用在招募开始前预先生成的计算机生成区组随机序列实施。随机分配表由一名独立工作人员生成并妥善保管,该工作人员不参与受试者入组判定、结局评估、数据预处理或统计分析

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

Random grouping will be implemented using a computer-generated block random sequence pre-generated before recruitment begins. The random allocation table is generated and properly kept by an independent staff member who does not participate in subject enrollment determination, outcome assessment, data preprocessing, or statistical analysis.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

被试将对刺激条件(真刺激 vs 假刺激)保持盲态。负责行为任务施测、fNIRS采集、BMI测量及数据分析的研究人员将对分组信息保持盲态。分组信息仅向实施刺激的、受过培训的TMS操作者披露,该操作者不参与结局评估或数据分析。盲态编码(如A组/B组)将在数据集最终定稿且预先设定的分析完成前保持封存。

Blinding:

Participants will be blinded to stimulation condition (real vs sham). Study personnel responsible for behavioral task administration, fNIRS acquisition, BMI measurement, and data analysis will remain blinded to group allocation. Group assignment will be disclosed only to trained TMS operators delivering stimulation, who will not participate in outcome assessments or data analysis. Blinding codes (e.g., Group A/Group B) will be maintained until the analysis dataset is finalized and prespecified analyses are completed.
