背景情况:
- 爬楼梯的评估对于评估膝关节骨关节炎 (KOA) 患者的身体表现至关重要.
- 关于KOA爬楼梯的现有生物力学数据不一致.
- 单步任务模仿了在爬楼梯时与KOA疼痛相关的步态模式.
研究的目的:
- 在KOA患者中,在孤立的上升和下降任务中分析前后肢体的生物力学和电肌图 (EMG).
- 为了比较KOA患者与年龄相匹配的对照.
- 在楼梯谈判期间在KOA中识别不同的运动策略.
主要方法:

Bones of the Lower Limb: Femur and Patella
8.3K
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...

Bones of the Lower Limb: Tibia and Fibula
14.8K
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...

Ankle Joint
3.4K
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...
