概括

慢性脚不稳定性 (CAI) 改变了脚的机制,在切割任务中将压力转移到前脚骨头,并远离. 这种保护策略可能会影响CAI个体的长期足部适应.

科学领域:

生物力学生物力学
整形外科整形外科整形外科
运动医学运动医学

背景情况:

慢性脚不稳定性 (CAI) 研究往往忽视了足部的内部机制.
了解CAI中改变的足部应力对于伤害管理和康复至关重要.

研究的目的:

在切割任务期间评估CAI患者脚部骨和软组织应力分布.
为了比较CAI参与者,copers和非受伤的个人之间的内部脚力学.

主要方法:

开发了66个个性化的有限元脚模型,使用3D扫描和自由形式变形.
应用计算的阿基里斯肌力和测量的脚部压力作为模拟的边界条件.
在切割任务的中间,脱落和推开阶段分析骨和软组织应力.

主要成果:

与CAI参与者相比,健康的个体表现出较高的和周围软组织压力.
在CAI参与者显示显著增加了形和侧面前脚骨头的压力在中立和推开期间.
CAI参与者展示了一种保护策略,卸载了骨并增加了前脚负荷.

结论:

CAI涉及明显的足部内部压力模式,特别是在推出阶段.
在CAI中变化的负载可能代表脚疼痛的补偿机制.
需要进一步研究推出阶段机制,以了解CAI的长期脚部适应.

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....
