概括
与标准的下拐杖 (SAC) 相比,无手拐杖 (HFC) 改善了平衡控制,显著降低了全身的角动量. 大多数用户更喜欢HFCs,因为它们具有更好的稳定性和更少的运动限制.
科学领域:
- 生物力学 生物力学
- 辅助设备 辅助设备 辅助设备
- 康复工程 康复工程
背景情况:
- 标准巴拐杖 (SAC) 是常见的,但可能导致二次伤害和限制上肢功能.
- 无手拐杖 (HFC) 对平衡的影响,特别是对步行靴的影响,需要进一步研究.
研究的目的:
- 为了比较SAC与HFC对全身角动量 (RAM) 的影响,这是一个关键平衡指标.
- 评估步行靴与不同类型的拐杖一起使用对平衡控制的影响.
- 评估用户报告的结果,包括平衡信心,疼痛,舒适度和设备偏好.
主要方法:
- 17名参与者在四个条件下行走:没有拐杖,SAC,HFC,每个拐杖类型都有步行靴.
- 全身角动量 (RAM) 和四肢角速度在步行过程中被测量.
- 调查了平衡信心,疼痛,舒适度和设备偏好.
主要成果:
- 与HFC相比,使用SACs的步态显示出明显更高的四肢角速度和84%的RAM增加.
- 在平衡信心,疼痛或舒适性方面,SAC和HFC之间没有发现显著差异.
- 大多数参与者 (71.1%) 喜欢HFC而不是SAC.
结论:
- 与标准的手臂拐杖 (SAC) 相比,无手拐杖 (HFC) 似乎通过减少全身的角动量来提供更好的平衡控制.
- 碳化合物可以降低跌倒的风险,并改善需要 ambulatory 援助的个体的流动性.
- 尽管舒适度和疼痛评级相似,但用户偏好强烈支持HFCs,这表明有可能改善粘附和功能结果.

01:10Ankle Joint
1.6K
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...

The concept of angular momentum for a solid structure is illustrated as the cumulative result of the cross-product of the position vector of the mass element and the cross-product of the body's angular velocity with the position vector.
To put this equation into simpler terms, it can be reconfigured using rectangular coordinates. This involves choosing an alternative set of XYZ axes that are arbitrarily inclined with respect to the reference frame. The process of deriving the rectangular...
