强化和错误反影响行走. 步骤长度调节反映了上肢的伸展,但步骤宽度控制减少了探索,并改变了平衡机制的稳定性.
科学领域:
- 人类运动控制器
- 生物力学 生物力学
- 神经可塑性 神经可塑性
背景情况:
- 强化和错误反是运动学习和探索上肢运动的确立驱动因素.
- 以前的研究表明,没有奖励的运动促进了更大的探索,使神经系统能够根据运动变化来改进行动.
- 这项研究将这些发现扩展到运动,检查了对行走和平衡的反效应.
研究的目的:
- 为了研究强化和错误反对行走过程中的运动探索的影响.
- 为了确定不同类型的反对直立平衡控制的影响.
- 将步行中的运动探索与之前观察到的任务实现模式进行比较.
主要方法:
- 24名健康的年轻人在带有仪器的跑步机上行走,并对步骤的长度或宽度进行虚拟现实反.
- 视觉反表明了相对于目标区域的步骤参数;加强反为准确性提供了奖励.
- 使用Lag-1自相关性和脚滚动和步骤放置的线性模型来量化探索和平衡策略.
主要成果:
- 与步骤长度的错误反相比,增强反增加了电机探索,但不是步骤宽度.
- 错误反促进了纠正行为,导致更精确的步骤放置.
- 步幅反改变了平衡控制,使得质量中心与基线相比,对脚滚动的预测能力较低.
结论:
- 步行时的步长调节对反做出反应,类似于上肢达到任务.
- 在步幅任务中保持直立平衡需要减少电机探索.
- 反影响平衡控制机制,突出了勘探与稳定之间的权衡.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
