随机方法(请说明由何人用什么方法产生随机序列):

由研究者事先分别从1到80为每位脑卒中患者依次进行编号,确保每位患者有且只有一个编号;使用EXCEL为每位患者生成各自的随机数,将患者的各自随机数从小到大进行排序号(随机数相同的按照患者编号顺序进行排序);规定序号1~20的患者分配至MI-BCI训练同步ta-VNS组,序号21~40的患者分配至MI-BCI训练前ta-VNS组,序号41~60的患者分配MI-BCI训练后ta-VNS组;序号61~80的患者分配单纯MI-BCI训练组。

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

The researchers will assign each stroke patient a unique number from 1 to 80 in sequence, ensuring that each patient has only one number. Using EXCEL, a random number will be generated for each patient. These random numbers will then be sorted in ascending order (in cases where random numbers are identical, patients will be sorted according to their assigned numbers). Patients with sequence numbers 1–20 will be allocated to the MI-BCI training with synchronized ta-VNS group, those with sequence numbers 21–40 to the pre-MI-BCI ta-VNS group, those with sequence numbers 41–60 to the post-MI-BCI ta-VNS group, and those with sequence numbers 61–80 to the pure MI-BCI training group.
