概括
更宽的步幅有效地减少了膝关节骨关节炎患者的峰值膝关节引时刻和冲动. 一个机器人系统精确地确定了个性化康复策略的最佳步幅.
科学领域:
- 步态和关节负荷的生物力学.
- 骨科和康复工程. 骨科和康复工程.
背景情况:
- 步幅修改可以降低膝关节骨关节炎 (KOA) 患者的膝关节附加时刻.
- 确定最佳的主体特定的步幅是一个临床挑战.
研究的目的:
- 为了研究步幅宽度和膝关节附加瞬间 (PKAM) 的关系.
- 评估机器人步进系统在确定KOA管理最佳步幅时的有效性.
主要方法:
- 14名患有中膝关节关节炎的患者和14名健康对照参与了这项研究.
- 使用带有机动脚板的机器人步行系统来测试狭窄,中立和宽的步幅.
- 分析包括PKAM-步幅关系斜率和3D膝盖时刻,使用重复测量ANOVA.
主要成果:

01:23Knee Joint
2.3K
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...

01:16Bones of the Lower Limb: Femur and Patella
2.9K
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...
