概括
增加后肢角 (TLA) 增强了步行推进能力,但脚外骨架 (EXO) 无法单独增强. 对TLA的反可能会改善肢体缺陷的个体的推进能力,尽管必须监测稳定性.
科学领域:
- 生物力学 生物力学
- 人类运动科学科学 人类运动科学
- 康复工程 康复工程 康复工程
背景情况:
- 肢体推进缺陷在临床人群中很常见,通常是由于减少的足弹动力或尾随的肢体角度 (TLA).
- 脚外骨架 (EXO) 可以增加脚下曲动力,但同时TLA的减少限制了它们在改善推进能力方面的有效性,特别是在中风后的个体中.
- 了解TLA和EXO辅助之间的相互作用对于优化步行康复策略至关重要.
研究的目的:
- 为了研究脚外骨架 (脚部柔器) 辅助和TLA反对步态推进的联合效应.
- 分析对关节力学和行走时稳定边缘的影响.
- 为了确定TLA反是否可以减轻常见于EXO使用的减少TLA的负面影响.
主要方法:
- 十个健康的个体在带有脚外骨架的仪器跑步机上行走.
- 参与者获得视觉反,以调节他们的峰值TLA到基线-5°,基线或基线+5°.
- 在0%,15%和35%的体重辅助级别时,EXO脚部曲器扭矩被应用.
主要成果:
- 随着更高的TLA,驱动脉冲显著增加,独立于EXO辅助.
- 更高的EXO辅助将机械工作转移到近距离,增加了脚对整个脚和部工作的贡献.
- 增加的TLA降低了前后稳定率,而更高的EXO援助增加了它.
结论:
- 通过反增加TLA可以增强步行推进,但这可能会损害稳定性.
- 单独使用脚外骨架并没有改善推进能力;然而,将它们与TLA反相结合显示了潜在的潜力.
- 在使用脚EXO时维护TLA的视觉反可能使脚EXO能够将关节益处转换为改善脚部推进能力,对于患有脚下器缺陷的人来说.

Bones of the Lower Limb: Femur and Patella
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 neck...
Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
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...
Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

Muscles of the Leg that Move the Foot and Toes
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.
