生物力学
运动医学
预防伤害

背景情况:

脚扭伤是常见的伤害,通常与降落过程中的生物力学因素有关.
了解着陆机制与AS风险之间的关系对于制定有效的预防策略至关重要.

研究的目的:

调查单脚降落 (SDL) 时的负载率 (LR) 与脚扭伤相关的生物力学因素之间的关系.
确定LR是否可以作为脚扭伤风险的预测标记.

主要方法:

十七名健康的年轻人从20厘米的平台上进行SDL.
三维运动分析和力传感器捕获着陆动力学和动力学.
肌肉骨建模软件评估长肌的参数.

主要成果:

荷载率 (LR) 与部曲,膝盖曲和脚背曲有负相关性.
较高的LR与长肌激活时间的延迟存在正相关性.
降低平面关节运动和延迟的肌肉激活与更高的LR相关.

结论:

在SDL期间较高的LR与导致脚扭伤的生物力学因素有关,包括关节运动减少和长激活延迟.
负载率可能是识别脚扭伤风险较高的个体的有价值的临床标记.
这些发现可以为预防脚扭伤提供有针对性的干预措施.

Ankle Joint

Ankle Joint

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...
