概括
患有慢性脚不稳定 (CAI) 的足球运动员表现出膝盖-脚协调的改变,在跑步时更多地依赖膝盖控制. 这表明,远至近距离的补偿策略是负载依赖的,对康复至关重要.
科学领域:
- 生物力学和运动控制
- 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) 与下肢生物机械变化有关.
- 对于CAI患者的膝关节关节协调,人们的了解有限.
研究的目的:
- 为了研究CAI和健康对照的足球运动员与健康对照者之间的斜平面动力学差异.
- 分析足球运动员的膝关节协调策略,在不同的运动负荷下 (走路与跑步).
主要方法:
- 40名男性足球运动员 (20名CAI,20名对照) 在跑步机上进行了步行和跑步任务.
- 3D运动捕捉记录了膝盖和脚动力学.
- 统计参数映射 (SPM) 和矢量编码 (VC) 分析了动力学数据和协调模式.
主要成果:
- 与对照组相比,CAI参与者在跑步时显著减少了脚背部屈曲和膝盖屈曲.
- 矢量编码揭示了CAI中向近位主导策略 (增加膝盖依赖) 的转变.
- 特定的步态周期阶段表明过渡到近端主导和刚性合,远端主导控制在摆动期间重新出现.
结论:
- 在CAI患者和健康个体之间,膝关节协调存在显著差异.
- 与CAI相关的运动控制适应是负载依赖的,采用远至近距离的补偿策略.
- 对CAI的康复计划应该整合联合协调之间的再培训,特别是对于高负载活动.

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...

Knee Joint
3.1K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

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...

Bones of the Lower Limb: Tibia and Fibula
8.8K
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...

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....
