概括
主动可变压缩鞋 (AVC-Shoes) 可实时调节脚硬度,以防止扭伤后的慢性不稳定. 这种新的脚支系统还可以通过增加行走过程中的腹肌活动来预防肌肉缩.
科学领域:
- 生物力学
- 康复工程
- 整形器械
背景情况:
- 急性脚扭伤通常会导致长期脚不稳定和肌肉缩.
- 目前的脚脚 (AFOs) 缺乏动态度调节,可能会恶化肌肉缩.
研究的目的:
- 引入主动可变压缩鞋 (AVC-Shoes) 以实时调节脚硬度.
- 评估AVC-Shoes对肌肉活动的可变刚性能力和影响.
主要方法:
- 开发AVC-Shoes使用由"鞋跟锁带"启发的线材压缩机制.
- 对所有方向的脚硬度的实验测量 (背部曲,脚部曲).
- 对三名健康参与者进行初步人体试验,以评估腹肌活动.
主要成果:
- AVC-Shoes显示所有方向的脚硬度变化.
- 背部曲和脚部曲的硬度分别达到8.3和5.9Nm/rad.

01:10Ankle Joint
1.8K
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...

01:10Bones of the Lower Limb: Tibia and Fibula
5.0K
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...
