这项研究想回答：针对儿童和青少年的脑机接口临床试验，目前全球有多少、用什么样的设备、在研究什么病？因为成人的脑机接口已经给严重神经和神经肌肉残疾患者带来功能益处，儿童可能也能获益，但现状不清楚。
“Pediatric populations with similar conditions may likewise benefit, yet the scope and characteristics of pediatric BCI (pBCI) research remain unclear”
研究者希望系统描述全球儿童脑机接口临床试验的概况，用来帮助临床和监管决策。
“We systematically characterize the global clinical trial landscape of pBCI studies to inform clinical and regulatory strategies”
这是一项基于试验注册库的横断面描述性分析，研究当时正在招募、正在进行和计划中的儿童脑机接口临床试验。
“We conducted a registry-based cross-sectional descriptive analysis of recruiting, ongoing, and planned pBCI clinical trials”
研究人员在 ClinicalTrials.gov 和另外 3 个国际注册库中，用“脑机接口”等相关词检索，并把年龄限制在 0-17 岁。
“ClinicalTrials.gov and 3 international registries were searched using "brain-computer interface," "BCI," "brain-machine interface," "neural interface," "neuroprosthetics," and "EEG-based assistive technology" and limited to participants aged 0-17 years”
由两名审查者独立筛选并提取关键信息，比如设备类型、入组人数、持续时间和研究阶段；分歧通过讨论达成一致。
“Two independent reviewers screened records and extracted key study variables, including device type (implanted vs non-implanted), enrollment, duration, phase, and condition studied; discrepancies were resolved by consensus”
共有十一项研究符合条件，分布在 7 个国家。这说明儿童脑机接口试验数量还不多。
“Eleven studies met the inclusion criteria. Trials encompassed 7 countries”
其中八项研究评估非植入式设备，3 项评估植入式系统。
“Eight studies evaluated non-implanted devices and 3 for implanted systems”
非植入式试验的中位持续时间是 56.0 天（四分位距 42.0-182.6），植入式试验中位持续时间是 365.3 天（四分位距 91.3-1826.4 天）。植入式试验通常随访更久。
“Non-implanted trials had a median duration of 56.0 days (IQR: 42.0-182.6), whereas implanted trials had a median duration of 365.3 days (IQR: 91.3-1826.4 days)”
非植入式试验的中位入组人数是 29 人（四分位距 19-51.5 人；范围 8-400 人），植入式试验中位入组人数是 8 人（四分位距 3-30 人；范围 3-30 人）。非植入式试验通常规模更大。
“Non-implanted trials had a median enrollment of 29 participants (IQR: 19-51.5; range: 8-400), whereas implanted trials had a median enrollment of 8 participants (IQR: 3-30; range: 3-30)”
只有 4 项研究只招收儿童参与者，其他研究同时招收儿童和成人。这意味着儿童的数据可能和成人混在一起，不容易单独判断对儿童的效果和安全性。
“Only 4 studies exclusively enrolled pediatric participants; the others recruited both pediatric and adult participants”
作者承认，当前儿童脑机接口临床研究的范围仍然有限。
“Current pBCI clinical research remains limited in scope”
作者还承认，儿童在脑机接口研究中可能没有得到足够的优先。
“children may be inadequately prioritized in BCI research”
这项研究将检索范围限定为参与者年龄 0-17 岁，说明研究对象是儿童和青少年；他们属于需要特殊保护的群体。
“ClinicalTrials.gov and 3 international registries were searched using "brain-computer interface," "BCI," "brain-machine interface," "neural interface," "neuroprosthetics," and "EEG-based assistive technology" and limited to participants aged 0-17 years”
研究中有 3 项使用植入式系统，植入式设备需要手术，对儿童风险更高，伦理审查应特别关注手术风险和长期影响。
“Eight studies evaluated non-implanted devices and 3 for implanted systems”
只有 4 项研究只招收儿童参与者，其他研究同时招收成人和儿童；这可能使儿童的安全数据不够清晰。
“Only 4 studies exclusively enrolled pediatric participants; the others recruited both pediatric and adult participants”
原文没有说明这些试验如何取得儿童本人同意（如适用）以及父母或监护人的知情同意，伦理委员会需要追问。AI 分析
原文没有提到是否设立独立的数据安全监查委员会，也没有报告严重不良事件的处理机制，需要伦理委员会关注。AI 分析
脑机接口可能采集大脑信号等敏感数据，伦理审查应关注数据隐私和未成年人数据保护。AI 分析
- 脑机接口 (BCI)
- 一种让大脑信号直接控制外部设备的技术，比如用想法移动光标或机械臂。
- 植入式设备
- 需要通过手术放入体内的设备，风险较高但可能信号更好。
- 非植入式设备
- 放在体外读取信号的设备，通常风险较低，比如戴在头上的电极帽。
- 中位数
- 把所有数值从小到大排列，位于中间的那个数；比平均值更不容易受极端值影响。
- 四分位距 (IQR)
- 中间一半数据的范围，用来描述数据分散程度。
- 注册库
- 记录临床试验基本信息的公开数据库，如 ClinicalTrials.gov。
- 横断面描述性分析
- 在某个时间点对现有试验进行“快照式”描述，不做因果推断。

摘要Abstract
IntroductionBrain-computer interfaces (BCIs) have shown meaningful functional benefits for patients with severe neurologic and neuromuscular disabilities. Pediatric populations with similar conditions may likewise benefit, yet the scope and characteristics of pediatric BCI (pBCI) research remain unclear. We systematically characterize the global clinical trial landscape of pBCI studies to inform clinical and regulatory strategies.MethodsWe conducted a registry-based cross-sectional descriptive analysis of recruiting, ongoing, and planned pBCI clinical trials. ClinicalTrials.gov and 3 international registries were searched using "brain-computer interface," "BCI," "brain-machine interface," "neural interface," "neuroprosthetics," and "EEG-based assistive technology" and limited to participants aged 0-17 years. Two independent reviewers screened records and extracted key study variables, including device type (implanted vs non-implanted), enrollment, duration, phase, and condition studied; discrepancies were resolved by consensus.ResultsEleven studies met the inclusion criteria. Trials encompassed 7 countries. Eight studies evaluated non-implanted devices and 3 for implanted systems. Duration and enrollment differed descriptively between groups. Non-implanted trials had a median duration of 56.0 days (IQR: 42.0-182.6), whereas implanted trials had a median duration of 365.3 days (IQR: 91.3-1826.4 days). Non-implanted trials had a median enrollment of 29 participants (IQR: 19-51.5; range: 8-400), whereas implanted trials had a median enrollment of 8 participants (IQR: 3-30; range: 3-30). Only 4 studies exclusively enrolled pediatric participants; the others recruited both pediatric and adult participants.ConclusionsCurrent pBCI clinical research remains limited in scope, and children may be inadequately prioritized in BCI research.
