概括
个性化下部中位硬度鞋 (LMSS) 比标准LMSS或形更有效地显著减少膝盖引的时刻. 这种方法有望通过优化生物力学来管理膝关节骨关节炎的进展.
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:
- 中间膝关节骨关节炎 (OA) 的进展与行走生物力学有关,特别是膝关节加伸 (KAM) 和曲 (KFM) 时刻.
- 下部中部度鞋 (LMSS) 的开发目的是为了减少OA管理的KAM.
- 在OA干预中,LMSS的最佳硬度比率仍在研究中.
研究的目的:
- 测试LMSS中个别定制的刚度比率是否与标准化比率相比产生更大的KAM降低.
- 为了比较个体在个性化和标准化LMSS之间实现KAM减少 (KFM增加或不增加) 的比例.
- 为了比较LMSS干预与侧内.
主要方法:
- 在15名OA患者和14名无症状个体中分析了行走生物力学.
- 参与者穿着具有不同,个性化和最小硬度比率的LMSS,以及侧内.
- 在行走过程中测量了膝盖引时刻 (KAM) 和膝盖曲时刻 (KFM).
主要成果:
- 与标准化比率 (6.7%-12.5%) (p < 0.001) 相比,个性化的硬度比率实现了显著更大的KAM减轻 (14.0%-16.4%).
- 较高的OA参与者百分比减少了KAM而没有增加KFM与个性化比率对最小比率 (p=0.001).
- 个体化比率也显示,与相比,无症状个体也有好处 (p=0.015).
结论:
- 与非个性化方法相比,在LMSS中个性化度比率在减少KAM方面表现出更高的有效性.
- 这种个性化策略可能会提高个体修改步态生物力学的能力.
- 需要进一步的研究来确认个性化的LMSS对OA结果的临床影响.

Knee Joint
3.0K
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...

Ankle Joint
2.7K
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...
