概括

面部同运动 (FS) 涉及广泛的面部肌肉激活,而不仅仅是受影响的侧面. 即使是简单的面部运动也会在FS患者的整个面部触发非自愿的肌肉活动.

科学领域:

神经学神经学
生物医学工程生物医学工程
发动机控制器的控制器

背景情况:

面部同运动 (FS) 是面部后面部肌肉协调的障碍.
在FS中面部肌肉网络参与的程度尚未完全理解.

研究的目的:

调查FS涉及面部两侧面部肌肉的整个网络的假设.
与健康对照人群相比,在FS患者的自愿面部运动中描述肌肉激活模式.

主要方法:

双边面部高分辨率表面电肌图 (HR-sEMG) 使用58个电极.
由36名FS患者和36名健康成年人执行的标准化面部运动任务.
使用线性混合效应模型分析肌肉激活模式.

主要成果:

健康对照组显示,自愿运动的主要肌肉活动最高.
在FS患者表现出非主肌肉在协同运动和逆侧肌肉的活性显著更高.
复杂,广泛的面部肌肉激活模式在FS患者在自愿运动期间观察到.

结论:

在FS中面部运动涉及到复杂的活动模式,它只部分服务于预期的运动.
非初级和逆侧面肌肉的非自愿肌肉激活是FS的一个关键特征.
研究结果表明,在FS患者中,面部运动控制的全球重组.

Muscles for Facial Expressions

Muscles for Facial Expressions

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
