Abstract
Background: Information about the role of auditory input and motor control is limited.
Objectives: Assessment the relationship between auditory and vestibular information with specific motor and cognitive functions.
Methods: Posturography in 17 Pre-lingual Cochlear Implant Adolescents, (PCIA) age 14.06 ± 3.05 in four sensory conditions was analyzed: (A) eyes open, cochlear implant (CI) on, (B) eyes open, CI off, (C) eyes closed standing on a foam over a platform (ECFP) with CI on, and (D) ECFP, CI off. Gait velocity (GV) was registered by inertial sensors using a 10-meter test. Vestibulo-ocular reflex (VOR) was evaluated with the video head impulse test (VHIT) and visual spatial skill (VS) assessed with the WISC-V test.
Results: SV had no significant difference between conditions A and B (p = .2461). Comparing C and D, SV values decreased when CI was turned on (p = .0036). A significant linear relationship between VOR and GV (p = .0064) generating the VOR gain loss lower gait. Relationship between VOR and VS scores was no significant (p = .685).
Conclusions and significance: Auditory information is a relevant cue when somatosensory and visual inputs are modified and range of vestibular function influence in a dynamic motor activity as gait, facts which must be considered in the neurodevelopment control.

背景:在听觉输入和运动控制的作用方面, 其信息是有限的。
目的:探讨听觉和前庭信息与特定运动和认知功能的关系。
方法:对17例年龄为14.06±3.05的语前人工耳蜗植入青少年(PCIA)在四种感觉条件下进行分析:(A)睁眼, 耳蜗植入(CI)开启;(B)睁眼, CI关闭;(C)闭眼站立在平台上的泡沫上(ECFP), CI开启;(D)ECFP, CI关闭。用10米测试, 通过惯性传感器记录步态速度(GV)。采用视频头脉冲测试(VHIT)来评估前庭-眼反射(VOR), 采用WISC-V测试来评估视觉空间技能(VS)。
结果:A、B条件下, SV无显著性差异(P=.2461)。比较C和D, 当CI打开时, SV值降低(P=.0036)。VOR和GV之间的显著线性关系(p=.0064), 导致失去VOR获得的较低步态。VOR与VS值之间的关系不显著(P=.685)。
结论和意义:当躯体感觉和视觉输入被改动, 前庭功能的范围影响一个动态活动如步态时, 听觉信息是一个相关的线索。这是在神经发育控制方面必须考虑的事实。
