随机方法(请说明由何人用什么方法产生随机序列):

按照1:1:1的比例随机分配到A组:TIS-θ组;B组:TIS-γ组;C组:假刺激组。按照受试者进入研究的时间顺序,设置区组长度为3(即每个区组内包含3名受试者),54位受试者划分为20个区组。对划分得到的每个区组,利用简单随机化方法得到分组结果,即先给每个区组内的受试者编号(1-3号),然后从随机数字表中随机地从某个位置开始连续取3个随机数给区组内的每一个受试者,并根据大小给每个随机数编上序号,规定每个区组内随机数序号1的受试者进入A组,序号2的受试者进入B组,序号3的受试者进入C组。

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

Participants will be randomly assigned to one of three groups in a 1:1:1 ratio:(Group A: TIS-θ stimulation group; Group B: TIS-γ stimulation group; Group C: Sham stimulation group). A block randomization method will be used with a block size of 3 (i.e., each block contains 3 participants). A total of 54 participants will be divided into 20 blocks according to the chronological order of enrollment. For each block, a simple randomization procedure will be performed as follows: Participants within each block are numbered 1 to 3. Three consecutive random numbers are obtained from a random number table, starting from a randomly selected position. Each of the three random numbers is assigned a rank based on its value (from smallest to largest). Within each block, the participant corresponding to the smallest random number (rank 1) will be assigned to Group A, the participant with the middle random number (rank 2) to Group B, and the participant with the largest random number (rank 3) to Group C.

Calculated Results after the Study Completed public access:

公开/Public

盲法:

试验过程中实行受试者、评估者和操作者盲法,随机分组由主要研究者独立执行。TIS由专门的治疗技术人员执行,真刺激仪与假刺激仪外形及操作完全一致,仅将TIS刺激电流调节为0。量表和仪器评估由不了解分组、经过专业培训的医生或治疗师进行,数据分析由不了解治疗分组的专业人员进行。

Blinding:

Blinding will be applied to participants, outcome assessors, and intervention providers throughout the trial. Randomization will be carried out independently by the principal investigator. TIS will be administered by specialized treatment technicians. The active and sham stimulators are identical in appearance and operation, with the sole difference being that the stimulation current is set to zero for the sham condition. Outcome assessments using scales and instruments will be performed by trained physicians or therapists who are blinded to group allocation. Data analysis will be conducted by personnel blinded to treatment assignment.
