- 生物医学工程 生物医学工程
背景情况:
- 集成虚拟现实 (VR) 和触觉反的脑电脑接口 (BCI) 对脊髓损伤 (SCI) 中的神经康复有希望.
- 之前的案例研究表明,在患有完全T4SCI的患者中,在10次治疗后,下肢疼痛和非性运动减少.
- 这个BCI协议的长期可持续性,增强和潜在的神经机制仍然不清楚.
研究的目的:
- 为了研究延长BCI-VR神经康复方案在患有完全T4SCI的患者中持续的影响.
- 分析临床,行为和神经生理学数据,以评估长期结果.
- 探索与疼痛调节和运动功能恢复相关的神经机制.
主要方法:
- 延长了之前建立的BCI-VR神经康复方案,再进行24个会议 (共14个月).
- 分析了临床数据 (疼痛水平,生活质量),行为观察 (下肢运动) 和神经生理学数据 (EEG).
- 专注于F3电极的theta频段的神经活动,用于疼痛编码和下肢肌肉活动模式.
主要成果:
- 扩展协议维持或降低了疼痛水平,并提高了自我报告的生活质量.
- 非的下肢运动,类似于步态模式,经常出现在参与和缺乏压力的过程中.
- 神经分析表明,疼痛变化被编码在左前置电极F3.3的甲频段.
结论:
- 持续应用BCI-VR神经康复方案可提高生活质量,稳定SCI的疼痛减轻.
- 该协议可能会促进节奏性下肢肌肉活动模式的出现,这表明了步态.

Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
