神经反馈治疗糖尿病患者的神经性疼痛
2026年9月10日 更新者:Francois Pouwer、University of Southern Denmark
我们将开展一项高质量、盲法、随机对照试验 (RCT),严格测试基于脑电图的 NF 对糖尿病相关神经性疼痛患者的有效性:1) 降低疼痛强度和疼痛影响,2) 每日改善功能和生活质量。
研究概览
详细说明
20%-40% 的糖尿病患者会出现糖尿病性多发性神经病 (DPN),这通常表现为一种痛苦的并发症,严重降低生活质量。
目前针对神经性疼痛的标准药物治疗通常无效并且具有相当大的副作用。
因此,迫切需要更好的治疗选择。
大脑解释来自外周信号的方式可以通过学习某些技术来改变,这可以使患者能够改变与疼痛 DPN 相关的信号,从而体验到疼痛减轻。
神经反馈(NF)是一种很有前途的神经调节疗法,个人可以接收有关大脑神经生理信号的实时反馈,从而增强对大脑活动的意志控制,减少疼痛体验。
神经反馈使用连接到计算机屏幕的头皮脑电图电极,为个人提供实时反馈。
神经纤维化可以通过教导患者自行调节相关活动模式来缓解症状。
每当神经活动向期望的方向变化时就奖励人,就可以调节该活动。
尚未在患有疼痛 DPN 的患者中进行随机对照试验研究 NF。
这项丹麦-巴西拟议项目是第一个三盲随机对照试验,严格测试 EEG-NF 干预对糖尿病神经病理性疼痛 (NP) 的影响。
治疗将在两个随机组中进行 10 次以上:真实 EEG-NF 组和假 EEG-NF 组(安慰剂)。
巴西参与者还将接受(功能)磁共振成像 (fMRI) 扫描,以研究 NF 治疗如何瞄准和改变神经机制。
如果发现有效,低成本的 EEG-NF 可以为糖尿病和疼痛性神经病患者大规模提供和实施,并且低收入和中等收入国家也可以使用。

实验性的:真实脑电图神经反馈
NF干预组将收到基于真实实时脑电图活动的反馈

Traditional neurofeedback uses one or two electrodes to modulate activity within a specific frequency band.
Standardized Weighted Low Resolution Electromagnetic Tomography (swLORETA) analyzes the 3D distribution of intracortical brain electrical activity based on surface EEG recordings, enabling real-time brainwave imaging with a spatial resolution under one cubic centimeter.
This divides the brain into over 12,000 voxels, offering localization similar to fMRI while maintaining EEG's faster temporal resolution.
Source-localized NF can target specific, deeper brain regions, multiple Brodmann areas simultaneously, and provide feedback on connectivity between neural sources, enabling the training of specific neural networks.
swLORETA metrics are compared to a normative database of neurotypical brains to produce z-scores for each area and metric.
NeuroGuide is used within the FDA 510(k)-cleared NeuroGuide Analysis System (K041263); clearance does not imply treatment validation.

同时,假手术组的阈值保持固定,确保一致的 70% 正反馈率。
