概括
汽车运动病与特定的头部运动有关. 随着对称的横向运动,可变的纵向运动被更好地容忍,但结合变性和不对称性会使症状恶化.
科学领域:
- 生物力学 生物力学
- 人类因素工程 人类因素工程
- 神经科学是一个神经科学.
背景情况:
- 运动病和姿势不稳定之间的联系是在静态环境中建立的.
- 有限的研究存在于这种关系在动态环境中,如车辆.
研究的目的:
- 为了调查汽车乘客运动病和非驾驶活动期间头部运动之间的联系.
- 探索头部运动模式和数值模型对运动恶性严重性的预测能力.
主要方法:
- 一个实验性汽车乘坐模拟 (15分钟) 与56名参与者.
- 耳内传感器测量了头部的线性加速.
- 随时收集的主观运动恶心评级,以及UniPG模型估计.
主要成果:
- 在头部运动模式 (纵向和横向加速度变化,斜率,曲率) 和运动恶心之间发现了显著的关系.
- 报告了轻微的整体症状,但特定的运动模式与严重程度相关.
- UniPG模型准确地预测了67%的参与者经历了一些症状的主观评分.
结论:
- 头部运动的可变性和不对称性相互作用,影响运动恶心的严重程度.
- 头部纵向和横向加速的特定模式可以加剧症状.
- 使用头部运动数据的运动病预测模型可以提高乘客的舒适性和安全性.

Equilibrium and Balance
4.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Pathophysiology of Vomiting
270
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...
