研究目的:

本研究旨在通过随机对照试验,系统评估iTBS结合听觉刺激对昏迷患者促醒效果的有效性和安全性,深入探索皮层-丘脑环路在意识恢复中的神经机制,为临床制定标准化的治疗方案提供科学依据。  

Objectives of Study:

This study aims to systematically evaluate the efficacy and safety of intermittent theta-burst stimulation (iTBS) combined with auditory stimulation in promoting arousal in comatose patients through a randomized controlled trial. It will further investigate the neural mechanisms of the cortical-thalamic circuit in consciousness recovery, thereby providing a scientific basis for establishing standardized clinical treatment protocols.

干预措施:

使用Magstim Rapid2 Plus 1 TMS设备配备双锥形8字线圈,结合Brainsight 2.0神经导航系统进行iTBS干预,靶点定位通过个体化T1加权MRI图像,使用FreeSurfer软件进行皮层表面重建,结合功能连接数据确定最佳刺激点,使用神经导航系统精确定位。iTBS参数设置为爆发频率50Hz,每个爆发包含3个脉冲,爆发间隔200ms,2秒刺激和8秒间隔重复20次,刺激强度为80%静息运动阈值,每日2次连续10天

干预措施代码:

Intervention:

The iTBS intervention was administered using a Magstim Rapid2 Plus 1 TMS device equipped with a double-cone 8-coil, integrated with the Brainsight 2.0 neuronavigation system. Target localization was performed using individualized T1-weighted MRI images. Cortical surface reconstruction was conducted with FreeSurfer software, and the optimal stimulation site was determined by incorporating functional connectivity data, followed by precise targeting via the neuronavigation system. The iTBS parameters were set as follows: a burst frequency of 50 Hz, with each burst containing 3 pulses, an inter-burst interval of 200 ms, repeated in cycles of 2-second stimulation and 8-second rest for a total of 20 cycles. The stimulation intensity was set at 80% of the resting motor threshold (RMT), administered once daily for 10 consecutive days.

随机方法(请说明由何人用什么方法产生随机序列):

本研究的随机化流程为:首先由研究人员手动填写每位受试者的 CRS‑R 分数;系统根据预设界值(如 ≤8、9–12、≥13)自动将受试者划入对应的分层(Stratum1/2/3)。随后为每位受试者生成一个固定随机值(复制并粘贴为数值),并在每个分层内部分别计算该层的 1/3 与 2/3 分位数作为“分层后的分组界限”;受试者在该分层内根据其固定随机值落在前 1/3、1/3–2/3 或后 1/3 区间,自动分配至 Group1、Group2 或 Group3,从而保证每个分层内部均为 1:1:1 分布。同时,表格中保留另一列实时变化的随机数(RAND()),用于展示“单纯按总体随机数三等分”的分组结果(不用于实际分配),以便对照验证分层随机化的效果。最终分组以“分层后的自动分组”为准,与 SUBJID 无关,确保分层平衡与分配隐蔽。

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

The randomization procedure of this study is described as follows: First, researchers manually enter the CRS-R score of each participant. The system automatically assigns participants to corresponding strata (Stratum 1/2/3) based on preset cut-off values (i.e., <=8, 9–12, >=13). Subsequently, a fixed random value is generated for each participant (copied and pasted as a static numeric value). Within each stratum, the 1/3 and 2/3 quantiles are calculated separately as the stratified grouping boundaries. According to their fixed random values, participants in each stratum are automatically allocated to Group 1, Group 2, or Group 3 if their values fall into the first one-third, the middle one-third, or the last one-third interval, respectively, ensuring a 1:1:1 distribution within each stratum.Meanwhile, an additional column of dynamically changing random numbers (generated by the RAND() function) is retained in the spreadsheet to display grouping results based on simple overall tertile division of random numbers; this result is not adopted for actual allocation and is only used for comparative verification of the efficacy of stratified randomization. The final grouping is determined by the automatic stratified allocation, which is independent of the subject identification number (SUBJID), so as to guarantee stratified balance and allocation concealment.
