概括

穿性肢体损失导致上肢不对称,并改变了行走时的干部运动. 戴假肢可以改善上半身的运动,可能减少截肢者背部疼痛的风险.

科学领域:

生物力学生物力学
假肢手术假肢手术是一门专业.
人类运动分析人类运动分析

背景情况:

跨体 (TH) 肢体损失导致身体质量和肩膀运动能力降低.
遗弃假肢是常见的,尽管拥有,导致潜在的上肢补偿和疼痛.
了解TH肢体损失中的步态变化对于管理次要肌肉骨问题至关重要.

研究的目的:

为了研究TH肢体损失的个体的上肢不对称性和步行参数.
为了比较有假肢和没有假肢的步态与身体健康的对照.
为了确定假肢使用对补偿运动的影响.

主要方法:

八名男性TH参与者和八名男性对照者在自我选择的速度下进行了步态分析.
TH参与者完成了带有和没有假肢的试验.
分析了动力学 (手臂摆动,干位移) 和动力学 (干-骨盆运动) 数据.

主要成果:

与对照组相比,TH四肢损失导致完整四肢手臂摆动和不对称性更大.
由于缺少假肢,导致干部曲和侧向曲减少.
在TH参与者中观察到增加的干骨时刻.
时空步态参数在不同组或条件之间没有显著差异.

结论:

假肢使用会影响上肢动力学和TH肢损失的动力学.
戴假肢促进了更规范的上肢运动,可能减轻背部疼痛.
鼓励假肢使用,即使是被动的,对于TH截肢者来说很重要.

Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
