- 发动机控制器的控制器
背景情况:
- 穿皮脊髓刺激 (tSCS) 用于诱导神经可塑性和改善中风后的运动功能.
- 了解STSC期间的实时变化对于阐明运动恢复和神经可塑性的机制至关重要.
- 现有知识缺口存在于STSC下对扭矩发展速度和神经刺激度的实时变化.
研究的目的:
- 为了研究 tSCS 对扭矩发展速度的实时影响.
- 为了检查STSC对皮质脊髓刺激性的实时影响.
- 为潜在的神经康复应用提供对SCS机制的基础见解.
主要方法:
- 20名健康参与者接受了两项实验:一项SCS条件和一项对照条件.
- 在 tSCS 条件下,对 Th11-Th12 脊椎过程进行了刺激,其干肌感觉值是干肌感觉值的两倍.
- 实验1评估了爆炸性下肢延伸过程中扭矩发展的峰值速度;实验2测量了电机唤起的电位 (MEP) 幅度.
主要成果:
- 与基线相比,TCS期间扭矩发展的峰值速度显著增加 (P = 0.038).
- 与基线相比,SCS期间的MEP幅度也显著增加 (P = 0.047).
- 控制条件在任何一项措施中都没有产生重大变化.
结论:
- 在健康个体中,SsCS有效地提高了扭矩发展速度和皮质脊髓刺激能力.
- 这些发现支持SCS在神经康复策略中的潜在实用性.
