概括

足部内在肌肉,如Flexor Digitorum Brevis (FDB),在站立平衡中发挥着关键作用. 随着任务难度的增加,FDB和soleus (SOL) 之间的协同激活增加,突出显示了它们的稳定性相互作用.

科学领域:

生物力学生物力学
发动机控制器的控制器
康复科学康复科学康复科学

背景情况:

足部内在肌肉在站立平衡中的作用在康复中经常被低估.
足部内在肌肉和脚肌肉之间的相互作用尚不清楚.

研究的目的:

在不同难度的站立任务中调查Flexor Digitorum Brevis (FDB) 和soleus (SOL) 肌肉之间的协同激活模式.
了解足部内在肌肉如何为姿势控制做出贡献.

主要方法:

在各种站立姿势中记录了FDB,SOL,中部胃角 (MG) 和前 (TA) 的电肌图 (EMG) 活动.
测量了姿势摇摆 (压力中心,COP).
计算了FDB和SOL之间的EMG连贯性作为协同激活的度量.

主要成果:

在更具挑战性的平衡任务中观察到增加的姿势摇摆和肌肉活动.
在0-5 Hz和10-20 Hz频段中,FDB和SOL EMG活动之间发现了显著的连贯性.
一致性随着任务难度的增加而增加,特别是在10-20 Hz频段.

结论:

Flexor Digitorum Brevis (FDB) 对于在不同任务之间保持稳定的平衡至关重要.
FDB和soleus (SOL) 之间的协同激活是平衡控制的一个关键机制.
对平衡的临床干预应考虑足部内在肌肉和脚肌肉之间的相互作用.

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....
