- 运动医学 运动医学
- 整形外科 整形外科 整形外科
背景情况:
- 动态膝盖 (DKV) 与前十字带 (ACL) 损伤有关.
- DKV对ACL损伤的预测准确性需要进一步调查.
研究的目的:
- 为了研究疲劳对下肢生物力学在跳跃着陆期间的影响.
- 确定DKV是否可以通过疲劳引起,并确定其生物力学预测因子.
主要方法:
- 有控制的实验室研究涉及健康男性在疲劳协议后进行跳跃着陆.
- 参与者根据膝关节绑架时刻变化被分为诱导和非诱导的DKV组.

Bones 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...

Muscles that Move the Leg
2.8K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
