Group:

Experimental Group

Sample size:

干预措施:

tACS 真刺激 靶区:患侧初级运动皮层(M1)下肢代表区(Cz 后 1 cm,侧向患侧 2 cm,10-20 系统)。 参数:正弦交流电 20 Hz,强度 2 mA(峰-峰),持续 20 min。 疗程:1 次/日,5 日/周,连续 2 周,共 10 次。

干预措施代码:

Intervention:

Active tACS Target Area: Lower limb representation area of the affected primary motor cortex (M1) (1 cm posterior to Cz, 2 cm lateral to the affected side, 10-20 system). Parameters: Sinusoidal alternating current at 20 Hz, intensity of 2 mA (peak-to-peak), duration of 20 minutes. Regimen: Once daily, 5 days per week, for 2 consecutive weeks (total of 10 sessions).

Intervention code:

组别:

对照组

样本量:

27

Group:

Control Group

Sample size:

干预措施:

电极放置、界面及操作流程与实验组完全一致;仅于第0–30s与最后30s给予 0→2 mA→0 mA 斜坡电流,中间 19 min 无电流输出,以模拟皮肤刺痛感并保持盲态。

干预措施代码:

Intervention:

The electrode placement, interface, and operating procedures are identical to those used for the experimental group. The stimulator delivers a ramp current (0→2 mA→0 mA) only during the first 30 seconds and the last 30 seconds of the session, with no current output for the intervening 19 minutes. This is designed to mimic the initial skin tingling sensation and maintain blinding.

随机方法(请说明由何人用什么方法产生随机序列):

由独立研究人员按照 1:1 的比例将受试者随机分配至实验组和对照组。采用简单区组随机进行分组,区组长度为 6 。随机序列由 Matlab 软件生成,再由专人采用密封不透光信封法进行分配隐匿。

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

Participants will be randomly assigned to the experimental group and the control group in a 1:1 ratio by an independent researcher. A simple block randomization method will be used for grouping, with a block size of 6. The random sequence will be generated using Matlab software, and allocation concealment will be implemented by a designated person using sequentially numbered, opaque, sealed envelopes.

Calculated Results after the Study Completed public access:

公开/Public

盲法:

(1)受试者盲法:向所有受试者解释研究为 “不同类型的下肢运动功能康复治疗效果比较”,不明确告知具体分组,使其相信可能接受任何一种治疗方案,避免心理预期对疗效的影响。在tACS刺激过程中,对照组在开始与结束各接受 30s 2 mA斜坡电流,皮肤感觉与实验组一致,维持盲态。 (2)评估者盲法:下肢运动功能于专用评估室完成,评估者全程未参与治疗、不知分组;评估表仅含受试者编号,无干预标识。

Blinding:

(1) Participant Blinding: All participants will be informed that the study is a "comparison of the therapeutic effects of different types of lower limb motor function rehabilitation training." They will not be explicitly informed of their specific group allocation and will be led to believe they may receive any of the treatment protocols, in order to avoid the influence of psychological expectations on the therapeutic outcomes. During the tACS procedure, the control group will receive a 30-second ramp current at 2 mA at both the beginning and the end of the session. This ensures that the skin sensation is consistent with that of the experimental group, thereby maintaining the blind state. (2) Assessor Blinding: Assessments of lower limb motor function will be conducted in a dedicated evaluation room. The assessors will not participate in the treatment process throughout the study and will be unaware of group allocation. The assessment forms will contain only the participant's identification number, with no indicators of the intervention received.
