概括

患有慢性脚不稳定症 (CAI) 的个体表现出部肌肉激活和强度的改变. 单腿坐测试 (SLST) 可能有助于检测这些神经肌肉变化,特别是关节最大的激活.

科学领域:

生物力学生物力学
神经肌肉控制控制神经肌肉控制
运动医学运动医学

背景情况:

慢性脚不稳定性 (CAI) 与部肌肉功能改变有关.
靠近肌肉的缺陷可能导致CAI的病理生理学.

研究的目的:

评估单腿坐测试 (SLST) 是否可以区分CAI患者的近端肌肉激活.
为了比较CAI和没有CAI的个体之间的部肌肉力量.

主要方法:

一项病例对照研究比较了CAI,coper和对照组在SLST期间的部肌肉激活和强度.
表面电肌图测量了 gluteus maximus 和 medius 的激活.
手持式动力测量评估了部肌肉的强度 (侧向旋转器,延伸器,绑架器).

主要成果:

与Coper和对照组相比,CAI组在SLST期间表现出明显更大的关节最大激活.
患有CAI的个体表现出比合作者和对照组更弱的部侧旋转器强度.
与对照组相比,CAI组的部延伸器强度也较弱.

结论:

这些发现支持现有的关于CAI近端神经肌肉变化的文献.
SLST显示出作为评估CAI中 gluteus maximus激活的临床工具的潜力.
需要进一步的研究来确认这些激活差异的临床检测能力.

Ankle Joint

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 of the Leg that Move the Foot and Toes

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....

Muscles that Move the Leg

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...
