- 人类运动分析分析
- 整形外科 整形外科 整形外科
背景情况:
- 临床步态分析依赖于脚部细分,但在甲足区域的中侧划分缺乏强有力的证据.
- 优化细分对于准确的足部生物力学评估至关重要.
研究的目的:
- 为了确定步态分析中足骨的最佳中侧细分.
- 为了评估不同甲四肢分裂模型的断段刚性和角运动.
主要方法:
- 收集了45名健康成年人在赤脚行走时收集的3D运动捕捉数据.
- 量化十个半足子单位的刚性和相对于牛津脚模型 (OFM) 后脚的计算角度运动.
主要成果:

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.
