干预措施:

患者先接受 cTBS 预处理刺激,cTBS 刺激结束 10min 后再接受 iTBS 正式刺激。cTBS刺激参数为丛内频率 50Hz,丛间频率5Hz;每丛刺激个数为 3 个,连续 200 丛无间歇刺激,共 600 个脉冲,为时约 40s;iTBS 刺激参数为丛内频率 50Hz,丛间频率5Hz;每丛刺激个数为 3 个,刺激 2s,间歇 8s,重复 20 次,共600 个脉冲,为时约 192s。TBS 刺激强度为 80%RMT。每天 1次,每周 5 天,总共 3 周。

干预措施代码:

Intervention:

The patients received cTBS pretreatment stimulation, and 10 minutes after cTBS stimulation, they received iTBS. The cTBS stimulation parameters were 50Hz in the plexus and 5Hz in the interplexus. The number of stimuli in each cluster was 3, 200 consecutive clusters without intermittent stimulation, a total of 600 pulses, lasted about 40s. The iTBS stimulation parameters were 50Hz in the plexus and 5Hz in the interplexus. The number of stimuli per cluster was 3, the stimulation was 2s, the interval was 8s, the repetition was 20 times, a total of 600 pulses, for about 192s. TBS stimulation intensity was 80%RMT. The treatment was given once a day, 5 days a week for a total of 3 weeks.

干预措施:

先进行假 cTBS 预处理刺激,假刺激的干预靶点和刺激参数与真刺激一致。干预时使用专用假刺激线圈,该线圈可产生与真刺激相似的声响和轻微振动,受试者可以听到机器声音,但是大脑皮层接收不到脉冲磁的输出。cTBS 刺激结束 10min 后再接受 iTBS 正式刺激。iTBS 刺激参数为丛内频率 50Hz,丛间频率 5Hz;每丛刺激个数为 3 个,刺激 2s,间歇 8s,重复 20 次,共 600 个脉冲,为时约 192s;刺激强度为 80%RMT。每天 1 次,每周5天,总共 3 周。

干预措施代码:

Intervention:

The intervention targets and stimulation parameters of the sham stimulus were consistent with those of the real stimulus. A special sham stimulation coil was used during the intervention, which produced sound and slight vibration similar to the real stimulation. Subjects could hear the machine sound, but the cerebral cortex did not receive the output of the pulsed magnetic field. Ten minutes after the end of cTBS stimulation, the rats were formally stimulated with iTBS. The iTBS stimulation parameters were 50Hz in the plexus and 5Hz in the interplexus. Each cluster contained 3 stimuli, 2s stimulation, 8s interval, 20 repetitions, a total of 600 pulses, for 192s. The stimulus intensity was 80%RMT. The treatment was given once a day, 5 days a week for a total of 3 weeks.

随机方法(请说明由何人用什么方法产生随机序列):

按照随机数字表法将纳入的 54 名伴有下肢运动功能障碍的脑卒中患者随机分为预处理组(cTBS+iTBS+常规康复)、iTBS 组(假 cTBS+iTBS+常规康复)和常规康复组(假cTBS+假 iTBS+常规康复)。研究者首先使用 Excel 表格按顺序生成一组样本量为 54 的编号列,导入 SPSS 24.0 软件,利用软件先转换为 0-1 的随机数字,再转换为 1-48 的随机数字,最后随机分组为 0 组、1 组、2 组,其中数字 0 代表假刺激组,1 代表假预处理组,2 代表预处理组,每组都有 18 个个案。将分组方案依次保存至顺序编号的不透明信封中,所有的随机信封由一名不参与治疗和数据分析的研究者保存。在签署知情同意书和基线评价后,依据信封编号顺序分发至研究者,研究者开启信封获得每个患者的分组情况。

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

Fifty-four stroke patients with lower limb motor dysfunction were randomly divided into a pretreatment group (cTBS+iTBS+ conventional rehabilitation), an iTBS group (sham cTBS+iTBS+ conventional rehabilitation) and a conventional rehabilitation group (sham cTBS+ sham iTBS+ conventional rehabilitation). Firstly, Excel was used to generate a group of numbered columns with a sample size of 54, which were imported into SPSS 24.0 software. The software was used to convert them into 0-1 random numbers, then 1-48 random numbers, and finally randomly divided into group 0, group 1, and group 2. 1 represents the sham-pretreatment group and 2 represents the pretreatment group, with 18 cases in each group. The trial-group assignments were stored sequentially in sequentially numbered opaque envelopes, and all randomization envelopes were held by an investigator who was not involved in the treatment or data analysis. After informed consent and baseline evaluation, the envelopes were distributed in numbered order to the investigators, who opened them to obtain the assignment to each patient.
