概括
在年轻女性中,穿高跟鞋 (HHS) 显著增加了跌倒风险,并恶化了静态平衡. 即使是偶尔佩戴者在佩戴HHS时也会经历较差的平衡和增加的姿势摆动.
科学领域:
- 生物力学 生物力学
- 人类运动科学科学 人类运动科学
- 生理学 生理学 生理学
背景情况:
- 高跟鞋 (HHS) 是女性常穿的,可能会影响脚负荷和平衡.
- 了解HHS对姿势稳定性的影响对于预防伤害和表现至关重要.
- 以前的研究已经探索了HHS效应,但使用线性和非线性动态的全面分析不太常见.
研究的目的:
- 评估高跟鞋 (HHS) 对脚负荷和站立平衡的影响.
- 为了比较HHS对高经验 (HHE) 和偶尔经验 (HHO) 个体的影响.
- 分析线性和非线性姿势控制措施.
主要方法:
- 16名高跟鞋专家 (HHE) 和16名偶尔穿鞋者 (HHO) 参与.
- 参与者进行了跌倒风险测试 (FRT) 和双腿站立测试,赤脚和11厘米HHS.
- 使用压力映射 (Zebris) 和平衡系统 (Biodex) 评估姿势稳定性,分析压力中心 (CoP) 路径,速度,样本 (SampEn),碎形维度 (FD) 和最大Liyapunov指数 (LyE) 等参数.
主要成果:
- 在HHE组中,HHS增加了44%以上的跌倒风险.
- HHS显著增加了COP路径长度和速度约78% (HHO: +67%,HHE: +92%).
- 非线性测量 (FD,LyE) 与HHS在中侧方向上增加,表明适应能力增强,同时支持四肢负荷达到了70%.
结论:
- 高跟鞋显著损害了年轻女性的静态平衡.
- 对HHS的经验加剧了对平衡和跌倒风险的负面影响.
- 这些发现突出了HHS带来的生物力学挑战,影响着姿势控制和负载模式.

01:10Ankle 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...
01:28Muscles 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.
