概括

一个新的前庭植入物在双边前庭病变 (BVH) 的小鼠中部分恢复了耳石功能. 这项技术有望改善步行稳定性,减少BVH患者的干偏差.

科学领域:

神经科学是一个神经科学.
生物医学工程生物医学工程
耳鼻喉科耳鼻喉科耳鼻喉科

背景情况:

双边带病 (BVH) 影响全球数以百万计的人,导致衰弱的症状,如动和步态不稳定.
目前的前置器康复疗法是支持性的,但不能恢复前置器功能.
一个针对管和囊的前置植入物提供了一个潜在的治疗方法.

研究的目的:

在BVH的小鼠模型中评估前庭植入物的疗效.
评估不同刺激水平对耳皮功能和行为的影响.

主要方法:

在30只小鼠中进行了双边前体破坏,随后进行了前体植入手术.
小鼠被分为没有刺激,0.5V刺激和1.0V刺激组.
在干预后分析了耳垂眼反射 (OOR),前庭眼反射 (VOR) 和步态参数.

主要成果:

1.0V刺激显著改善了OOR反应,恢复了眼睛垂直旋转角度.
干部偏差在1.0V刺激时显著减少,与对照水平相比.
观察到步态的部分恢复,包括更窄的支基,尽管步伐的长度和速度没有改善.

结论:

The Vestibular System

The Vestibular System

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.
