概括

患有慢性脚不稳定 (CAI) 的人在视力受损时,在苛刻的任务中表现出改变的运动和肌肉激活. 这表明CAI可能会损害感官重权能力.

科学领域:

生物力学生物力学
发动机控制器的控制器
运动医学运动医学

背景情况:

慢性脚不稳定 (CAI) 影响在简单的任务中以视觉障碍影响运动模式.
视觉干扰对CAI复杂的降落切割运动的影响尚未得到充分理解.

研究的目的:

通过在降落切割任务期间通过光镜检查CAI视觉障碍期间的下肢动力学和肌肉激活的改变.

主要方法:

病例控制研究涉及18名患有CAI的个人和18名健康对照.
参与者进行了降落切割任务,带有和没有石眼镜 (SV与NSV).
在立场阶段测量下肢动力学和肌肉激活.

主要成果:

与NSV相比,CAI组在SV条件下显示出增加的脚逆转角度和长激活.
在任何一组的视觉条件之间都没有观察到膝盖或关节角度的显著差异.

结论:

视觉干扰在降落切割过程中引起CAI患者改变运动模式.
调查结果表明,在感官重权化方面存在潜在的缺陷,以适应CAI的视觉变化.

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...
