药物成份或治疗方案详述:

1.总体设计思路: 本研究是一项在单中心进行的观察性研究,核心方法采用被试内、2x2析因设计。 本研究的框架为探索性,旨在探索不同感觉输入组合对大脑活动的调节机制,而非验证某项干预措施的优效性或非劣效性。 本研究的报告将遵循STROBE(Strengthening the Reporting of OBservational studies in Epidemiology)指南。 2.析因设计 因素1:有无抓握视频 因素2:有无实物存在 无观察(屏幕显示静态“+”号) 有观察(屏幕上播放第一人称视角抓握药瓶的视频) 无实物(桌面空旷,无任何物体) A(无视频无实物) B(视频) 有实物(一个实物药瓶放在受试者左手正前方的桌面上) C(实物) D(视频+实物) 这两个因素组合成四种试验范式: ? 条件A (无视频无实物): 屏幕显示十字,面前无实物药瓶。要求受试者想象并尽力尝试对空做出抓握动作。 ? 条件B (有视频): 屏幕播放抓握药瓶的视频,面前无实物药瓶。要求受试者观察视频并同步、尽力尝试做出相同的抓握动作。 ? 条件C (有实物): 屏幕显示十字,面前放置实物药瓶。要求受试者看着药瓶,想象并尽力尝试去抓握它。 ? 条件D (视频+实物): 屏幕播放抓握药瓶的视频,同时面前放置实物药瓶。要求受试者观察视频并同步、尽力尝试去抓握面前的实物药瓶。 3.实验整体流程 每位受试者将在单次实验中,按照预先随机分配的顺序完成全部四个条件的实验区块(Block)。为控制顺序效应,区块的呈现顺序采用4x4平衡拉丁方设计。四个区块之间穿插5分钟的洗脱期,以最大程度减少前一任务对后一任务的持续影响。 (1)单个实验区块 (Block) 结构 每个实验区块对应一种实验条件(A, B, C或D),包含3轮,每轮包含10次试验(Trial),共计30次试验。每轮之间有10-15秒的随机休息时间,受试者可在此期间做深呼吸、放松疲劳。 (2)单次试验 (Trial) 结构 ①任务演示与准备: 实验开始前,屏幕上会放置一张第一人称视角做抓握动作的照片,让受试者明确任务。 ②静息态: 屏幕中央呈现一个“+”号,受试者保持放松,不要进行任何动作或特定思考。 ③任务态: 听到提示音后,受试者根据当前区块的条件(A/B/C/D),开始尽力尝试做出抓握动作。 A 想象并尽力尝试抓握动作(面前无药瓶)。 B 屏幕播放抓握药瓶的视频。要求受试者观察视频并同步地、尽力尝试做出相同的抓握动作(面前无药瓶)。 C 屏幕显示静态十字,面前放置药瓶。要求患者看着药瓶,想象并尽力尝试去抓握它。 D 屏幕播放抓握药瓶的视频,面前同时放置药瓶。要求患者观察视频并同步地、尽力尝试去抓握面前的实物药瓶。 ④BCI触发与反馈: BCI系统实时分析EEG信号。当检测到受试者的运动意图强度超过预设阈值时,智能手套即被触发,辅助患者完成一次完整的“抓握-放松”动作,为受试者提供实时的、与运动意图匹配的感觉(本体感觉和视觉)反馈。 ⑤休息间隔: 一次试验结束后,进入随机间隔,准备下一次试验。 (3) 洗脱期结构 在每两个实验区块之间,设置一个严格控制的5分钟洗脱期: ① 第1-2分钟:强制性休息与注意力脱离: 屏幕变为中性画面(如宁静的自然风景)。指导语提示受试者完全放松,不要再想任何与抓握有关的事情,可以闭眼休息或进行轻微的非任务相关活动(如活动一下颈部)。 ② 第3分钟:执行中性认知任务: 播放一段约60秒的、与运动完全无关的中性视频(如抽象几何图形的缓慢变化),以占据认知资源,进一步清除上一任务的影响。 ③ 第4分钟:静息态脑电基线采集: 屏幕恢复为静态的“+”号,采集60秒的静息态EEG数据。该数据用于检验受试者的脑活动是否已恢复到基线水平,确保洗脱期的有效性。 ④ 第5分钟:设备检查与准备: 检查EEG电极阻抗和sEMG电极贴片有无脱落,进行必要的调整,为下一个区块做准备。 (二)、技术路线 (一)研究设计与流程 1.总体设计思路: 本研究是一项在单中心进行的观察性研究,核心方法采用被试内、2x2析因设计。 本研究的框架为探索性,旨在探索不同感觉输入组合对大脑活动的调节机制,而非验证某项干预措施的优效性或非劣效性。 本研究的报告将遵循STROBE(Strengthening the Reporting of OBservational studies in Epidemiology)指南。 2.析因设计 因素1:有无抓握视频 因素2:有无实物存在 无观察(屏幕显示静态“+”号) 有观察(屏幕上播放第一人称视角抓握药瓶的视频) 无实物(桌面空旷,无任何物体) A(无视频无实物) B(视频) 有实物(一个实物药瓶放在受试者左手正前方的桌面上) C(实物) D(视频+实物) 这两个因素组合成四种试验范式: ? 条件A (无视频无实物): 屏幕显示十字,面前无实物药瓶。要求受试者想象并尽力尝试对空做出抓握动作。 ? 条件B (有视频): 屏幕播放抓握药瓶的视频,面前无实物药瓶。要求受试者观察视频并同步、尽力尝试做出相同的抓握动作。 ? 条件C (有实物): 屏幕显示十字,面前放置实物药瓶。要求受试者看着药瓶,想象并尽力尝试去抓握它。 ? 条件D (视频+实物): 屏幕播放抓握药瓶的视频,同时面前放置实物药瓶。要求受试者观察视频并同步、尽力尝试去抓握面前的实物药瓶。 3.实验整体流程 每位受试者将在单次实验中,按照预先随机分配的顺序完成全部四个条件的实验区块(Block)。为控制顺序效应,区块的呈现顺序采用4x4平衡拉丁方设计。四个区块之间穿插5分钟的洗脱期,以最大程度减少前一任务对后一任务的持续影响。 (1)单个实验区块 (Block) 结构 每个实验区块对应一种实验条件(A, B, C或D),包含3轮,每轮包含10次试验(Trial),共计30次试验。每轮之间有10-15秒的随机休息时间,受试者可在此期间做深呼吸、放松疲劳。 (2)单次试验 (Trial) 结构 ①任务演示与准备: 实验开始前,屏幕上会放置一张第一人称视角做抓握动作的照片,让受试者明确任务。 ②静息态: 屏幕中央呈现一个“+”号,受试者保持放松,不要进行任何动作或特定思考。 ③任务态: 听到提示音后,受试者根据当前区块的条件(A/B/C/D),开始尽力尝试做出抓握动作。 A 想象并尽力尝试抓握动作(面前无药瓶)。 B 屏幕播放抓握药瓶的视频。要求受试者观察视频并同步地、尽力尝试做出相同的抓握动作(面前无药瓶)。 C 屏幕显示静态十字,面前放置药瓶。要求患者看着药瓶,想象并尽力尝试去抓握它。 D 屏幕播放抓握药瓶的视频,面前同时放置药瓶。要求患者观察视频并同步地、尽力尝试去抓握面前的实物药瓶。 ④BCI触发与反馈: BCI系统实时分析EEG信号。当检测到受试者的运动意图强度超过预设阈值时,智能手套即被触发,辅助患者完成一次完整的“抓握-放松”动作,为受试者提供实时的、与运动意图匹配的感觉(本体感觉和视觉)反馈。 ⑤休息间隔: 一次试验结束后,进入随机间隔,准备下一次试验。 (3) 洗脱期结构 在每两个实验区块之间,设置一个严格控制的5分钟洗脱期: ① 第1-2分钟:强制性休息与注意力脱离: 屏幕变为中性画面(如宁静的自然风景)。指导语提示受试者完全放松,不要再想任何与抓握有关的事情,可以闭眼休息或进行轻微的非任务相关活动(如活动一下颈部)。 ② 第3分钟:执行中性认知任务: 播放一段约60秒的、与运动完全无关的中性视频(如抽象几何图形的缓慢变化),以占据认知资源,进一步清除上一任务的影响。 ③ 第4分钟:静息态脑电基线采集: 屏幕恢复为静态的“+”号,采集60秒的静息态EEG数据。该数据用于检验受试者的脑活动是否已恢复到基线水平,确保洗脱期的有效性。 ④ 第5分钟:设备检查与准备: 检查EEG电极阻抗和sEMG电极贴片有无脱落,进行必要的调整,为下一个区块做准备。 

Description for medicine or protocol of treatment in detail:

1. Overall Design Concept: This study is a single-center observational research, adopting a within-subject 2×2 factorial design as the core method. The framework of this study is exploratory, aiming to investigate the regulatory mechanisms of different sensory input combinations on brain activity, rather than verifying the superiority or non-inferiority of a specific intervention. The reporting of this study will follow the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. 2. Factorial Design Factor 1: Presence or absence of grasping videos Factor 2: Presence or absence of real objects These two factors combine to form four experimental paradigms: - Condition A (no video, no real object): A cross is displayed on the screen, and there is no real medicine bottle in front of the subject. The subject is required to imagine and make every effort to perform an empty-handed grasping movement. - Condition B (with video): A video of grasping a medicine bottle is played on the screen, but there is no real medicine bottle in front of the subject. The subject is required to watch the video and synchronously make every effort to perform the same grasping movement. - Condition C (with real object): A static cross is displayed on the screen, and a real medicine bottle is placed in front of the subject. The subject is required to look at the medicine bottle, imagine it, and make every effort to grasp it. - Condition D (video + real object): A video of grasping a medicine bottle is played on the screen, and a real medicine bottle is placed in front of the subject simultaneously. The subject is required to watch the video and synchronously make every effort to grasp the real medicine bottle in front of them. 3. Overall Experimental Process Each subject will complete all four experimental blocks in a pre-randomized order within a single experiment. To control for order effects, the presentation order of blocks adopts a 4×4 balanced Latin square design. A 5-minute washout period is inserted between the four blocks to minimize the persistent impact of the previous task on the subsequent one. (1) Structure of a Single Experimental Block Each experimental block corresponds to one experimental condition (A, B, C, or D) and includes 3 rounds, with 10 trials per round, totaling 30 trials. A random rest period of 10-15 seconds is set between rounds, during which the subject can take deep breaths and relax to reduce fatigue. (2) Structure of a Single Trial 1) Task demonstration and preparation: Before the experiment starts, a photo of a first-person perspective grasping movement is displayed on the screen to make the subject clear about the task. 2) Resting state: A "+" is presented in the center of the screen, and the subject is required to stay relaxed without performing any movements or specific thinking. 3) Task state: After hearing a prompt tone, the subject starts to make every effort to perform the grasping movement according to the condition of the current block (A/B/C/D): - A: Imagine and make every effort to perform a grasping movement (no medicine bottle in front). - B: A video of grasping a medicine bottle is played on the screen. The subject is required to watch the video and synchronously make every effort to perform the same grasping movement (no medicine bottle in front). - C: A static cross is displayed on the screen, and a medicine bottle is placed in front. The subject is required to look at the medicine bottle, imagine it, and make every effort to grasp it. - D: A video of grasping a medicine bottle is played on the screen, and a medicine bottle is placed in front simultaneously. The subject is required to watch the video and synchronously make every effort to grasp the real medicine bottle in front. 4) BCI triggering and feedback: The BCI system analyzes EEG signals in real-time. When the detected intensity of the subject's motor intention exceeds the preset threshold, the smart glove is triggered to assist the subject in completing a full "grasp-relax" movement, providing real-time sensory (proprioceptive and visual) feedback that matches the motor intention. 5) Rest interval: After one trial ends, a random interval begins to prepare for the next trial. (3) Structure of the Washout Period A strictly controlled 5-minute washout period is set between every two experimental blocks: 1) Minutes 1-2: Mandatory rest and attention disengagement: The screen displays a neutral image (e.g., a peaceful natural landscape). Instructions prompt the subject to fully relax, stop thinking about anything related to grasping, and may close their eyes to rest or perform slight non-task-related activities (e.g., moving the neck). 2) Minute 3: Performing a neutral cognitive task: A 60-second neutral video unrelated to movement (e.g., slow changes of abstract geometric figures) is played to occupy cognitive resources and further eliminate the impact of the previous task. 3) Minute 4: Resting-state EEG baseline collection: The screen returns to a static "+" to collect 60 seconds of resting-state EEG data. This data is used to verify whether the subject's brain activity has returned to the baseline level, ensuring the effectiveness of the washout period. 4) Minute 5: Equipment inspection and preparation: Check for any detachment of EEG electrode impedances and sEMG electrode patches, and make necessary adjustments to prepare for the next block.

随机方法(请说明由何人用什么方法产生随机序列):

随机化: 本研究为被试内设计,不涉及将受试者随机分配到不同的干预组。随机化主要用于确定四种实验条件(A, B, C, D)的呈现顺序,以平衡和控制顺序效应(如学习、疲劳)。 (1)随机序列的产生: 将采用4x4平衡拉丁方设计,预先生成所有可能的平衡序列。此过程将由一名不参与受试者招募和数据采集的研究人员,使用计算机软件(如在R或MATLAB环境中编程实现)完成。 (2)分配方法: 生成的序列将被编号。当一名合格的受试者入组时,负责招募的研究助理将按照入组的先后顺序,为该受试者分配下一个可用的序列编号。例如,第1、5、9、13、17、21位入组的受试者分配序列1,第2、6、10、14、18、22位分配序列2,以此类推。

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

Randomization: This study adopts a within-subject design and does not involve random allocation of subjects to different intervention groups. Randomization is mainly used to determine the presentation order of the four experimental conditions (A, B, C, D) to balance and control order effects (such as learning and fatigue). (1) Generation of random sequences: A 4×4 balanced Latin square design will be used to pre-generate all possible balanced sequences. This process will be completed by a researcher not involved in subject recruitment or data collection using computer software (e.g., programmed in R or MATLAB environments). (2) Allocation method: The generated sequences will be numbered. When an eligible subject is enrolled, the research assistant responsible for recruitment will assign the next available sequence number to the subject in the order of enrollment. For example, the 1st, 5th, 9th, 13th, 17th, and 21st enrolled subjects will be assigned Sequence 1; the 2nd, 6th, 10th, 14th, 18th, and 22nd will be assigned Sequence 2, and so on.

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:

1.数据采集 (1) 启动刺激呈现程序和EEG/EMG同步记录系统。 (2) 按照拉丁方分配的顺序,依次进行A, B, C, D四个条件的实验模块。 (3) 每个模块包含30个试次,试次结构为:休息期(3秒)-> 听觉提示(1秒)-> 任务期(4秒)-> 试次间期(3-5秒随机)。 (4) 模块间提供2-3分钟休息。 2.数据管理 (1)数据采集: 原始EEG/EMG数据将以标准化格式保存在专用的研究服务器上。 (2)数据匿名化: 所有数据文件和纸质记录均使用唯一的受试者ID进行标识,不包含任何个人身份信息。 (3)数据存储与备份: 电子数据将存储在受密码保护的加密服务器上,并进行每日增量备份和每周完全备份。纸质文件(如知情同意书)将存放在上锁的文件柜中。 (4)数据质量控制: 将制定数据核查计划,由两名研究人员独立检查数据录入的准确性,并定期检查数据完整性。

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

1. Data Collection (1) Launch the stimulus presentation program and the EEG/EMG synchronous recording system. (2) Conduct the experimental blocks for the four conditions (A, B, C, D) in sequence according to the order assigned by the Latin square. (3) Each block contains 30 trials, with the trial structure as follows: rest period (3 seconds) → auditory cue (1 second) → task period (4 seconds) → inter-trial interval (random 3-5 seconds). (4) A 2-3 minute rest will be provided between blocks. 2. Data Management (1) Data acquisition: Raw EEG/EMG data will be stored in a standardized format on a dedicated research server. (2) Data anonymization: All data files and paper records will be identified using a unique subject ID, without containing any personal identifying information. (3) Data storage and backup: Electronic data will be stored on a password-protected and encrypted server, with daily incremental backups and weekly full backups. Paper documents (e.g., informed consent forms) will be stored in locked file cabinets. (4) Data quality control: A data verification plan will be developed, where two researchers will independently check the accuracy of data entry, and data completeness will be inspected regularly.
