概括
对于运动恶心高度敏感的个体在接受前体刺激时会经历更大的姿势不稳定. 这表明前庭输入显著影响那些容易发动车痛的人的平衡.
科学领域:
- 神经科学是一个神经科学.
- 人体生理学 人体生理学
- 感官整合 感官整合
背景情况:
- 运动病是一种常见的疾病,是由身体运动引发的.
- 姿势控制依赖于整合视觉,体感和前庭信息.
- 之前的研究表明,在运动恶性时,姿势控制发生了变化,特别是在视觉/体感障碍时,但前庭效应仍然不清楚.
研究的目的:
- 为了研究 sinusidal电气前庭刺激 (EVS) 对 postural 控制在不同运动恶心易感的个体的影响.
- 为了确定前庭刺激是否不同地影响姿势稳定性,基于动作病的易感性.
主要方法:
- 50名参与者被分为三组,根据运动恶心的易感性进行分类.
- 在四个条件下,使用经过修改的临床感官整合和平衡测试 (mCTSIB) 协议来评估姿势控制.
- 这些条件在基线和在1mA,1hz阴侧EVS期间被测试.
主要成果:
- 在基线时,两组之间没有观察到姿势控制的显著差异.
- 在EVS期间,高度易感运动病的个体表现出增加的姿势不稳定性.
- 这种效应在眼睛闭在坚固表面的条件下最为明显.
结论:
- 垂体刺激似乎不成比例地影响着对运动恶心高度敏感的个体的姿势控制.
- 研究结果表明,改变前体处理或感官集成在运动性 motion sickness 中可能发挥作用.
- 需要对更大的队列和各种感官扰乱进行进一步的研究.

01:15Equilibrium and Balance
5.1K
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...

01:29The Vestibular System
40.2K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:28Major Somatic Sensory Pathways
1.3K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...
