- 运动医学 运动医学
背景情况:
- 尽管有进展,反复出现的侧脚扭伤 (LAS) 和慢性脚不稳定 (CAI) 仍然很普遍.
- 了解CAI需要全面的下肢分析,包括多段脚模型和近接关节动态.
研究的目的:
- 为了比较 CAI 的男性与健康对照群的步行过程中的多段脚和下肢动力学.
- 为了研究CAI中部绑架器强度和正面平面脚动力学之间的关联.
主要方法:
- 对50名男性 (25名CAI,25名对照) 的横截面研究,使用3D运动捕获进行步态分析.
- 通过Biodex动力学评估多段脚和近端关节动力学,并通过Biodex动力学评估等比性部强度.
- 统计参数映射 (SPM) 用于组比较和相关性分析.
主要成果:
- 在CAI组在终端摆动 (88-93%的步态周期) 期间表现出明显更大的横平面骨绑架.
- 在其他部,膝盖或脚部部段动力学方面,没有发现显著的群体间差异.
- 没有观察到部绑架器强度和脚前部平面动力学之间的显著相关性.
结论:
- 患有CAI的雄性在终端摆动期间在横平面上显示出改变的后脚动力学.
- 多段脚模型有效地检测微妙的偏差,强调摇摆阶段的意义.

Bones of the Lower Limb: Femur and Patella
4.8K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Ankle Joint
2.8K
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
3.9K
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....

Bones of the Lower Limb: Tibia and Fibula
8.9K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
