概括

外骨行走最初会增加大脑活动,但随着练习变得更有效率. 这项研究表明,在熟悉脚外骨后,皮层参与减少.

科学领域:

神经科学是一个神经科学.
生物力学生物力学
人与计算机的交互

背景情况:

了解皮质对外骨使用的适应,对于开发直观的辅助设备至关重要.
关于大脑如何适应外骨架辅助运动的研究有限.

研究的目的:

为了研究外骨架辅助行走期间的皮质反应.
检查熟悉对这些皮质反应的影响.

主要方法:

使用了脑电图 (EEG),心电图 (EMG) 和运动捕捉.
健康的参与者用脚外骨架以1.2m/s的速度行走,有或没有以前的经验.

主要成果:

最初的外骨使用导致了显著的生物机械和皮质变化,增加了大脑的参与.
经过简短的熟悉后,增加的α频段皮质功率表明皮质参与减少.

结论:

外骨架辅助行走涉及到动态皮质调整.
熟悉导致在外骨使用期间更有效的神经处理.
这些发现可以为更集成的外骨系统的设计提供信息.

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
