概括
神经硬,而不是肌肉硬,与脚的背部屈曲范围有关. 在较大的脚角处,较高的神经度与较小的最大背部屈曲角相关.
科学领域:
- 生物力学 生物力学
- 肌肉骨系统 运动系统
- 神经科学是一个神经科学.
背景情况:
- 脚的背部屈曲受到三肌肌肉硬度和伸展耐力的限制.
- 神经硬可能反映这些局限性,但尚未与肌肉硬同时研究.
- 这些硬度和脚最大背部屈曲之间的关系尚不清楚.
研究的目的:
- 为了研究脚最大背部屈曲角度和三肌肌肉和部神经硬度之间的相关性.
- 要确定脚神经硬是否是脚背伸缩范围的决定因素.
主要方法:
- 41名健康的成年人接受了足最大背部屈曲的测量.
- 剪切波速度是组织刚性的指标,测量了三肌和神经在5°,15°和25°的背部屈曲处.
- 用多个线性回归分析 (强制输入和分步方法) 来评估相关性.
主要成果:
- 神经剪切波速与所有测量角度 (强迫进入方法) 的最大脚背部屈曲有显著的负相关性.
- 三肌肌肉的剪切波速度与脚最大的背部屈曲没有显著的相关性.
- 逐步回归确定了25°背部屈曲时的小腿神经度,作为最大脚背部屈曲的唯一显著预测因素.
结论:
- 神经硬,特别是在较高程度的脚背部屈曲时,似乎是限制最大运动范围的关键因素.
- 在健康的成年人中,肌肉硬与脚最大的背曲角没有直接相关.
- 这些发现凸显了神经组织机制在关节运动范围中的重要性.

Ankle Joint
2.8K
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 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....

Pulse Assessment Sites
2.5K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Bones 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...
