概括

最初的头部姿势在后部冲击时显著改变了头部和部的运动,即使部肌肉活动的变化很小. 这项研究有助于为司机制定更好的伤害预防策略.

科学领域:

生物力学生物力学
发动机控制器的控制器
伤害生物力学伤害生物力学

背景情况:

后撞车碰撞是部受伤的常见原因.
驾驶员在后部撞击时的头部姿势可能会影响受伤风险.
了解头部和部动力学对于预防伤害至关重要.

研究的目的:

量化初始头部姿势对部肌肉活动的影响.
在模拟后部撞击期间分析头部和部动力学.
为预防伤害和计算建模提供数据.

主要方法:

十二名参与者经历了模拟后部冲击雪.
测试了五种不同的头部初始姿势:左肩检查,左镜检查,中性,后视镜检查,看着乘客.
记录了部肌肉电肌图 (EMG) 和头部/干动力学.

主要成果:

与中性相比,非中性姿势的大多数肌肉的前冲击肌肉活动增加.
撞击期间部肌肉活动的峰值在姿势之间显示出最小的变化.
与中性姿势相比,非中性姿势导致头部加速更大,头位移变化更大.

Muscles that Move the Head

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
