概括
患有脑 (CP) 的儿童表现出更大的关节接触力 (HJCF) 非对称性,主要是由他们的步态模式驱动的,而不是骨结构. 干预措施应针对步态正常化,以防止大腿形.

- 神经肌肉疾病 神经肌肉疾病
背景情况:
- 大脑 (CP) 通常涉及步态不对称和骨变形.
- 改变关节负荷 (关节接触力 - HJCF) 可以导致病态的股骨生长.
- 步态模式和股骨形态都会影响HJCFs.
研究的目的:
- 为了比较CP儿童和典型发育 (TD) 儿童之间的HJCF不对称性.
- 确定骨形态或步行模式是否是儿童HJCF不对称的主要驱动因素.
- 为了告知临床干预措施来管理CP的股骨形变.
主要方法:
- 使用MRI和3D步态分析数据创建了特定对象的肌肉骨模型.
- 使用OpenSim软件计算了关节接触力 (HJCF).

01:16Bones of the Lower Limb: Femur and Patella
2.6K
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...

Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.
