概括
假肢对齐调整并没有改变腰部或腰部关节负荷,在座位对立期间,对于跨腿截肢 (TTA) 的人来说. 与对照组相比,患有TTA的人经历了更高的联合力.
科学领域:
- 生物力学 生物力学
- 假肢和整形手术
- 肌肉骨健康 肌肉骨健康
背景情况:
- 截肢截肢 (TTA) 的个人报告了更高的腰部和部疼痛率.
- 在日常活动中改变运动和负荷,如坐到站,可能会导致这种疼痛.
- 假肢对齐对坐立时关节负荷的影响尚不清楚.
研究的目的:
- 为了研究假肢对齐对TTA患者腰部和腰部关节负荷的影响,在坐到站任务期间.
主要方法:
- 收集了动力学数据,地面反应力和肌肉活动数据,这些数据来自10名TTA患者和10名对照者.
- 在患有TTA的参与者中测试了6个规定的和改变的假肢对齐 (前/后,中间/侧,短/高).
- 使用肌肉骨模型计算部和L4-L5关节负荷.
主要成果:
- 不同的假肢对齐之间没有观察到部或L4-L5关节负荷的显著差异.
- 与截肢侧相比,患有TTA的参与者在完整的一侧表现出更大的峰值关节接触力.
- 与对照组相比,患有TTA的个体表现出较高的L4-L5关节接触力.
结论:
- 在TTA患者中,假肢对齐的变化没有影响TTA患者在坐立时的部或腰部关节负荷.
- 建议进一步研究涉及动态任务,以探索假肢对齐在关节负荷中的作用.

Anatomical Positions
16.4K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Bones of the Lower Limb: Femur and Patella
8.2K
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...

Muscles of the Leg that Move the Foot and Toes
5.1K
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....
