概括

患有慢性脚不稳定 (CAI) 的人在跑步和跳跃着陆时表现出下肢生物力学变化,而不是走路. 这些变化可能反映了感官运动缺陷或保护策略,为CAI提供未来干预信息.

科学领域:

生物力学生物力学
运动医学运动医学
整形外科整形外科整形外科

背景情况:

慢性脚不稳定 (CAI) 与下肢缺陷和动态活动期间改变的生物力学有关.
之前对CAI生物力学在各种任务中的研究表明,由于不同的方法和定义,结果相互矛盾.

研究的目的:

调查与没有CAI的个体之间在走路,跑步和跳跃着陆期间下肢生物力学上的差异.

主要方法:

一项病例控制研究将17名CAI患者与15名健康人群进行了比较.
在行走,跑步和跳跃着陆过程中,分析了斜和正面平面脚/部角度和时刻,以及中侧脚平衡 (MLFB).
使用统计参数映射 (SPM) 和离散变量比较.

主要成果:

在群体之间散步时没有观察到任何显著的生物力学差异.
在跑步过程中,CAI组表现出减少的足部曲瞬间和更大的横脚偏差.
在跳跃着陆中,CAI组在接触后显示部延伸器时刻和部引角度增加.

结论:

脚和部的生物力学变化存在于CAI患者在跑步和跳跃着陆时,但不是走路时.
这些发现表明CAI中潜在的感觉运动障碍或补偿策略,指导未来的康复策略.

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....
