- 老年学是一门学科.
背景情况:
- 部,膝盖或脚的末期关节炎会导致步态变化.
- 在这些条件下,步行稳定性的差异尚未得到充分理解.
研究的目的:
- 将患有关节炎 (HA),膝关节炎 (KA) 和脚关节炎 (AA) 的患者的动态步行稳定性与健康对照者 (HC) 进行比较.
- 为了确定与关节炎的位置相关的特定步行稳定性缺陷.
主要方法:
- 在行走过程中测量了前后后 (AP) 和中侧 (ML) 稳定性边缘 (MoS).
- 包括30个HA,20个KA,30个AA和30个HC参与者.

01:10Ankle 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...

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...
