概括
结合3D打印的内和脚扩展器改善了功能平脚 (FF) 个体的生物力学. 这种方法提供了一种实用的,非侵入性的方法来增强足部功能并减少补偿性肌肉活动.
科学领域:
- 生物力学 生物力学
- 整形手术 整形手术
- 运动医学 运动医学
背景情况:
- 功能性平脚 (FF) 与较差的下肢生物力学,效率低下的负载转移和过度使用伤害有关.
- 3D打印的内和脚对FF生物力学和神经肌肉控制的综合影响尚不清楚.
研究的目的:
- 研究3D打印的内 (SI),脚 (Toe) 和它们的组合 (SI+Toe) 对FF的年轻成年人的步态,力量中心 (COF),脚对齐和肌肉激活的直接影响.
- 为了比较FF个体和健康对照之间的生物机械和神经肌肉反应.
主要方法:
- 十个FF个人和十个对照在四个条件下行走:只穿鞋子,SI,脚和SI+脚.
- 使用OptoGait评估了步行参数,使用F-Scan评估了COF轨迹,使用Kinovea评估了脚角,并通过表面EMG评估了肌肉活动.
主要成果:
- 与对照人群相比,FF个体表现出中位的COF偏差,增加了脚变动,以及改变了肌肉活动.
- 在FF个体的SI+Toe干预减少了中间COF偏差,减少了脚变动,延长了立场阶段 (平脚),缩短了推进阶段.
- 在推进过程中,SI+Toe增加了半骨和骨前部活动,同时保持了减少的胃角骨和骨活动.
结论:
- 3D打印的内和脚的组合使得FF患者的脚对齐和肌肉激活模式立即得到改善.
- 整合定制整形器与脚伸展元件是一个可行的非侵入性策略,用于增强下肢生物力学,并可能减少临床环境中的受伤风险.

01:10Ankle Joint
2.7K
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...

01:28Muscles of the Leg that Move the Foot and Toes
3.9K
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....

01:10Bones of the Lower Limb: Tibia and Fibula
8.7K
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...
