概括

铜人在走路时表现出明显的脚内协调模式,与慢性脚不稳定 (CAI) 的人不同. 这些独特的动力学策略可以预防健康个体的反复扭伤.

科学领域:

生物力学生物力学
整形外科整形外科整形外科
运动学运动学

背景情况:

慢性脚不稳定性 (CAI) 往往先于反复的脚扭伤.
在没有复发性扭伤 (copers) 的个体中了解脚的运动协调对于预防CAI至关重要.
步行时关节"放松"的情节凸显了在此活动中研究足内协调的必要性.

研究的目的:

为了识别和描述步行时脚内关节协调模式.
分析与CAI和健康对照个体相比,铜人中足内协调的变异性.

主要方法:

一组12名铜工,13名CAI患者和10名对照人员在跑步机上以1.3米/秒的速度行走.
修改的矢量编码技术被用来计算脚内关节之间的合角度,代表关节间的协调.
评估了协调变异性,使用在立场阶段合角度的标准偏差.

主要成果:

与CAI和对照组相比,Copers在中间姿势期间在前面平面的后脚和中脚之间显示出明显较少的反相协调 (近距离主导).
在斜脚平面中,在中立姿势期间,铜人比CAI组显示的中脚和前脚之间的相位协调 (远距离主导) 显著减少.
在copers中中脚和前脚之间的前面平面协调在晚期姿势中表现出较低的反相与远程主导比在CAI组. 标足中脚-前脚协调变异性在铜人中低于CAI个体.

结论:

鉴定到的足内协调的差异及其在copers的变化可能解释他们的能力,以避免反复的脚扭伤.
这些发现提供了关于铜匠使用的神经肌肉策略的见解,以在行走时保持脚关节稳定.

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...

Muscles of the Leg that Move the Foot and Toes

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
