概括
修改运行形式以脚或前脚冲击 (FFS) 增加膝盖接触力 (KCF). 这些变化可能不会减少膝关节骨关节炎 (OA) 的关节负荷,因此应谨慎处理.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
背景情况:
- 膝关节骨关节炎 (OA) 是一种普遍存在的退行性关节疾病,影响身体活动.
- 修改跑步生物力学被探索为一种减轻OA患者膝关节关节负荷的策略.
研究的目的:
- 调查改变的跑步技巧,特别是前脚冲击 (FFS) 和脚外跑,对膝盖接触力 (KCF) 的影响.
主要方法:
- 十名健康的参与者在三个条件下进行了地面跑步试验:自然跑步,FFS和脚跑步.
- 用基于OpenSim的肌肉骨模型估计了膝盖接触力 (KCF).
- 统计分析涉及单向重复测量ANOVA,以在各种条件中比较KCF.
主要成果:
- 与自然和FFS运行相比,出脚的运行在早期姿势中显示出更高的中侧KCF.
- 无论是FFS还是toe-out运行都增加了中侧侧面KCF,而不是自然运行.
- FFS运行导致垂直KCF显著高于自然和脚外运行.
结论:
- 跑步修改,如出脚和FFS可以增加膝盖接触力,特别是在中侧方向.
- 这些生物力学变化可能对减少膝关节OA患者的关节负荷没有好处.
- 在考虑这些运行修改用于膝关节OA管理时,建议谨慎.

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...

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....

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...
