概括

在圆步行期间的功能电刺激 (FES) 在健康成年人中减少了膝盖加动时刻. 这种方法可能有助于减少膝关节骨关节炎 (KOA) 患者的中枢膝盖负荷.

科学领域:

生物力学生物力学
神经肌肉电刺激是一种神经肌肉电刺激.
骨关节炎的研究研究.

背景情况:

膝关节骨关节炎 (KOA) 与机械负荷有关,特别是在膝关节中间区.
对KOA的干预通常旨在平衡作用于中枢膝盖的力量.
了解减少膝关节 adduction 时刻的方法对于KOA管理至关重要.

研究的目的:

研究功能电刺激 (FES) 对降低膝关节引峰时刻 (pKAM) 的影响.
在健康成年人和中部KOA的个体中,在踏步时评估双腿骨和侧面腹肌的FES.
评估使用圆训练与FES结合使用的可行性.

主要方法:

一项试点研究涉及16名健康人群和5名中部KOA患者.
参与者踏上了仪器仪表的圆系统,测量力量和动力学.
测试了三个FES条件:侧面胃角 (FES_LG),双腿骨 (FES_BF) 和同时 (FES_LGBF) 与没有FES的基线步骤相比.

主要成果:

与基线相比,健康参与者在所有三种FES条件下都显示出明显较低的pKAM (p < 0.05).
患有KOA的个体表现出与FES较低的pKAM趋势,尽管由于样本大小而不是统计学上显著.
发现使用FES的圆步行是可行的.

结论:

功能性电刺激与圆训练相结合,可以减少膝关节中间区的负荷.
这种结合的方法可能会增强目标肌肉力量的产生.
需要对更大的KOA队伍进行进一步的研究,以确认有效性.

关键词:

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...
