干预措施代码:

Intervention:

Subjects received functional electrical stimulation of the rectus femoris and tibialis anterior muscles, with each session lasting 20 min, 10 sessions per week, 2 sessions per day, for 4 weeks.

干预措施:

受试者会根据屏幕视频的指示,想象患侧下肢进行伸膝和踝背屈的动作。受试者通过佩戴无创脑电采集设备,脑电信号将被采集,并被实时分析解码。信息处理系统将分辨患者的运动意图,并转化为电信号输出为适宜强度的电刺激,以加强肢体活动,并提供反馈。每次治疗时长 20 分钟,每星期完成 10 次训练,每天完成 2 次,持续 4 周。在此基础上,进行用物理因子治疗、运动疗法、作业疗法、常规康复治疗等临床中常用的康复治疗

干预措施代码:

Intervention:

Subjects will be instructed by a screen video to imagine performing knee extension and ankle dorsiflexion movements with the affected lower limb. Non-invasive EEG acquisition devices will be worn to collect EEG signals, which will be real-time analyzed and decoded. The information processing system will identify the patient’s motor intent and convert it into electrical signals to deliver appropriately calibrated electrical stimulation to enhance limb movement and provide feedback. Each treatment session lasts 20 minutes, with 10 sessions per week (2 sessions per day) for a total duration of 4 weeks. On this basis, conventional clinical rehabilitation therapies—including physical agents, exercise therapy, occupational therapy, and routine rehabilitation—are administered.

随机方法(请说明由何人用什么方法产生随机序列):

采用基于电子数据采集系统的中心随机化方法进行分配隐藏。由系统内置模块依据预设的区组随机算法生成并维护随机分配序列。符合入选标准的受试者完成基本信息录入后,系统将自动执行随机化分配,并生成一个唯一的随机化编码。该编码与组别信息的对应关系处于盲态,由其监管,仅在试验需要揭盲时方可解锁,以此确保分配过程的公正性与不可预测性。

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

The allocation concealment was performed using a centralized randomization method based on an Electronic Data Capture (EDC) system. The built-in system module generated and maintained the randomization sequence according to a pre-established block randomization algorithm. After eligible participants had their baseline information entered, the system automatically executed the randomization assignment and generated a unique randomization code. The correspondence between this code and the actual group assignment remained blinded and under the supervision of Duan Chunyu. It was only to be unlocked at the time of trial unblinding, thereby ensuring the impartiality and unpredictability of the allocation process.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究使用的EDC系统在数据采集、记录、审核、传输等方面都具备严格的要求和流程,以确保临床试验数据的准确性、完整性和安全性。 数据采集:使用电子病例报告表(eCRF),数据管理人员在设计eCRF时对所需采集的数据点进行预先定义,研究人员通过EDC系统直接录入或导入数据。 数据记录:EDC系统支持实时数据录入;EDC系统具有自动记录数据修改痕迹的功能;源数据保存。 数据审核:EDC系统具备自动逻辑核查功能以及人工逻辑核查;配置数据质疑管理模块;源数据核查确认。 数据传输:数据传输过程中应采用加密技术,确保数据在传输过程中的安全性;确保传输的数据完整无损;对于外部数据的传输,应约定明确的传输方法和频率,并规定数据传输失败时的重新传输流程,以确保数据的及时性和完整性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The EDC system used in this study adheres to stringent requirements and procedures for data collection, recording, review, and transmission to ensure the accuracy, completeness, and security of clinical trial data.Data Collection: Electronic Case Report Forms (eCRFs) are employed. Data managers predefine required data points during eCRF design, and investigators directly enter or import data through the EDC system.Data Recording: The EDC system supports real-time data entry; it automatically logs data modification traces; source data is preserved.Data Verification: The EDC system incorporates automated and manual logic checks; it includes a data query management module; source data verification and confirmation are performed.Data Transmission: Encryption technology must be employed during data transmission to ensure security; transmitted data integrity must be guaranteed; for external data transfers, explicit transmission methods and frequencies must be agreed upon, along with defined retransmission procedures for failed transfers to ensure timeliness and completeness.
