概括
在中风幸存者中,可以使用40°以下的峰值膝盖曲和12°以下的运动范围从脚到峰值曲来确定膝盖硬的步态. 这些标准有助于对中风康复研究进行一致的诊断.
科学领域:
- 生物力学
- 神经学
- 康复科学
背景情况:
- 膝盖硬是中风后常见的运动障碍.
- 目前还没有标准化的诊断标准.
- 这项研究旨在确定可靠的标准,以确定中风幸存者的膝盖硬.
研究的目的:
- 确定合适的标准来诊断中风幸存者的膝盖硬.
- 为了促进对中风步态的研究进行一致的比较.
- 在中风幸存者中分析特定的膝盖曲参数.
主要方法:
- 使用10米的步道和运动捕捉系统来记录步行.
- 分析的膝盖曲参数:曲的峰值,运动的总范围 (RoM周期),RoM曲 (脚到曲的峰值),以及曲的峰值时间.
- 在24名中风幸存者和24名年龄/性别匹配的对照者之间比较了步态参数,检查了和非的四肢.
主要成果:
- 21名中风幸存者表现出膝盖硬的特征.
- 与对照组和非性肢体相比,这些个体的性肢体的峰值摆动,RoM摆动和RoM周期显著减少.
- 性肢体的曲时间比非性肢体更早.
结论:
- 在摇摆阶段,膝盖曲率<40°是一个关键指标.
- 膝盖运动范围从脚到峰值曲<12°是另一个关键标准.
- 这两个参数提供了最合适的标准来确定中风幸存者的膝盖硬.

01:23Knee Joint
3.4K
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...

01:27Degenerative Disc Disease I: Introduction
29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
