概括
在前十字带重建后,青年运动员在切割过程中表现出改变的运动模式. 足部进展角度可以通过修改生物力学和改善下肢控制来帮助减少再伤的风险.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
背景情况:
- 前十字带 (ACL) 损伤在年轻运动员中很普遍,通常与方向变化 (COD) 运动有关.
- 脚前进角度 (FPA) 在切割过程中影响下肢动力学,但其与青年ACL重建后生物力学关系未得到充分研究.
- 膝盖绑架和部 adduction 是 ACL 损伤的既定预测因素.
研究的目的:
- 调查膝盖最大曲时脚的进展角度与预测ACL损伤的生物力学因素之间的关联.
- 分析这些关系,在一个45度的运行切割任务在青年运动员后ACL重建.
主要方法:
- 三十四名青少年运动员 (15.0 ± 2.5岁) 接受了ACL重建,参加了比赛.
- 参与者在受影响和不受影响的四肢上执行了45度的运行切割任务.
- 采用三维运动捕捉和强力板来收集干和下肢生物力学.
主要成果:
- 在FPA和干部,骨盆,部,膝盖和脚的角度之间发现了中等的相关性,以及受影响四肢的脚时刻 (r = -0.340.52).
- 在未受影响的肢体上,观察到骨盆,部和脚角的中等相关性 (r = 0.410.44).
- 在骨盆,部和膝盖角度以及膝盖时刻 (p ≤ 0.038) 发现了显著的四肢间差异.
结论:
- 年轻运动员可能会在ACL重建后采取切割运动模式,从而增加他们再次受伤的风险.
- 足部进展角度是一个可修改的因素,临床医生和教练可以利用它来减轻运动员受伤风险.

Bones of the Lower Limb: Femur and Patella
2.0K
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...

Relative Motion Analysis - Acceleration
313
A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

Muscles of the Leg that Move the Foot and Toes
1.1K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
