概括
主要的上肢截肢导致大脑不对称. 持续的甲爆刺激 (cTBS) 通过调节受影响半球的皮质脊髓刺激性 (CE) 暂时减少了这种不平衡.
科学领域:
- 神经科学是一个神经科学.
- 康复医学 康复医学 康复医学
- 发动机控制器的控制器
背景情况:
- 大型上肢截肢 (mULA) 会导致神经可塑性变化,影响康复和假肢使用.
- 以前的研究表明,截肢 (CLH) 的另一半球中皮质脊髓刺激性 (CE) 增加,这表明潜在的不适应性半球间失衡.
研究的目的:
- 在慢性mULA患者中评估基线CE.
- 为了研究持续的甲突破刺激 (cTBS) 对主要运动皮层 (M1) 应用的急性影响,与截肢对CE.
主要方法:
- 13名患有慢性mULA的成年人接受了电生理学评估.
- 运动唤起电位 (MEP) 幅度在cTBS前和之后在5分钟和10分钟测量.
- 线性混合模型分析了半球,时间及其相互作用的影响.
主要成果:
- 在CLH中观察到较高的MEP幅度,与基线时的ipsilateral半球相比.
- 在刺激后5分钟,cTBS在刺激后的CLH中暂时降低了MEP振幅.
- 这种减少导致半球间不对称的暂时减弱,在10分钟后部分恢复.
结论:
- 在慢性mULA患者中,cTBS可以暂时调节CE.
- 观察到的cTBS的影响似乎仅限于刺激的半球.
- 这项研究提供了mULA后半球间CE不对称性的初步证据,并建议cTBS作为潜在的调制工具,需要进一步调查.

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...
