概括
在健康个体中,限制脚推进并没有增加对方腿上的膝关节力量. 这表明,其他关节的补偿运动可以防止增加膝盖负荷,但对于那些有病理的人来说,需要进一步研究.
科学领域:
- 人类运动的生物力学.
- 骨科生物力学和伤害风险评估.
背景情况:
- 脚推进缺陷,由于整形或截肢,可能会增加对侧膝盖负荷.
- 这可能会增加膝盖疼痛和骨关节炎的风险.
研究的目的:
- 研究如何限制单侧脚推进力的影响对健康个体的对侧膝关节负荷.
主要方法:
- 18名健康人带有或没有脚脚节骨架 (AFO) 限制脚推进,走路.
- 步态分析测量了脚力量,关节工作和地面反应力.
- 使用OpenSim计算了对侧膝关节接触力.
主要成果:
- 脚限制减少了高峰脚推进力和工作的50%左右.
- 双侧膝关节的工作增加,但对侧膝关节关节力量没有显著差异.
- 前面的地面反应力冲动保持不变,表明补偿推进.
结论:
- 健康的个体可以弥补减少的脚推进力,而不会增加对侧膝盖负荷.
- 对于那些患有病理限制补偿策略的个体,需要进一步的研究.

01:10Ankle Joint
1.5K
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...

01:16Bones of the Lower Limb: Femur and Patella
2.4K
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...
