概括
经过前十字带重建 (ACLR) 的运动员表现出改变的跳跃着陆生物力学,增加了第二次ACL受伤的风险. 测试期间的认知挑战加剧了这些障碍,突出了在回归体育评估中进行双重任务查的必要性.
科学领域:
- 生物力学 生物力学
- 运动医学 运动医学
- 神经科学是一个神经科学.
背景情况:
- 第二次前十字带 (ACL) 损伤的高风险在重建后 (ACLR) 持续存在.
- 在认知上要求苛刻的情况下,往往会发生ACL损伤.
- 双任务查可以通过同时评估认知和运动技能来识别运动障碍.
研究的目的:
- 为了评估ACLR后持续的认知运动障碍.
- 假设ACLR运动员与对照人群相比,会表现出受损的跳跃着陆生物力学.
- 假设认知挑战会使这些生物力学障碍恶化.
主要方法:
- 控制实验室研究比较35个ACLR个体与35个匹配的健康对照 (HC).
- 参与者在各种条件下进行跳跃着陆,包括认知挑战 (决策,视觉空间任务).
- 测量了关键变量,例如膝盖延伸器时刻不对称 (KEM-Asym-IC) 和膝盖曲角 (pKFA) 的峰值.
主要成果:
- 与HC组相比,ACLR组在初接触时表现出明显更大的膝盖延伸器时刻不对称 (P < .001).
- 在快速决策条件下 (P < .001) 两组都表现出减少的峰值膝盖曲角度 (P < .001).
- 没有发现显著的群体条件相互作用.
结论:
- ACLR运动员在跳跃着陆过程中表现出与第二次ACL受伤风险相关的生物力学缺陷,即使在回归运动许可后也是如此.
- 认知挑战,特别是快速决策,在ACLR和HC组中减少了膝盖曲.
- 需要进一步的研究来探索神经认知挑战,以加强ACLR回归体育评估.

Ankle Joint
2.8K
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...

Knee Joint

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...
