概括

与年龄相关的听力损失 (ARHL) 与较差的姿势控制有关,特别是在头部运动方面. 单脚姿势与侧向头部倾斜有效地识别了老年人听力障碍的平衡受损.

科学领域:

老年学是一门学科.
听力学听力学是指听力学.
神经科学是一个神经科学.

背景情况:

与年龄相关的听力损失 (ARHL) 影响了相当一部分成年人群.
在ARHL患者中,静脉系统退化是常见的.
姿势控制对于保持平衡和预防老年人跌倒至关重要.

研究的目的:

为了评估ARHL的成年人的姿势控制.
为了研究30°横向头部倾斜对姿势控制措施的影响.
确定用于检测ARHL的余额赤字的敏感措施.

主要方法:

招募了50-70岁的正常听力 (n=10) 和ARHL (n=32) 的成年人.
评估听力 (纯音调听力测量),前庭功能 (vHIT,cVEMPs,oVEMPs) 和姿势控制 (SLS,RF,TW).
利用皮尔森相关性和线性回归来分析关系.

主要成果:

ARHL与减少的cVEMP和oVEMP振幅有显著的相关性.
单腿姿势 (SLS) 与侧向头部倾斜显示,随着ARHL的增加,性能下降.
没有发现vHIT增益,没有头部倾斜的SLS,TW或RF的显著相关性.

结论:

增加的ARHL与姿势控制的下降有关,特别是头部侧向倾斜.
在ARHL人群中,静脉功能降低.
侧向头部倾斜的SLS是检测ARHL中姿势控制减弱的敏感措施,可以帮助评估跌倒风险.

Equilibrium and Balance

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...
