目的：通过人工耳蜗（CI）良好控制的听觉刺激与身体平衡之间的关系很少被研究。本研究的目的是评估CI患者的身体平衡功能，有和没有声音在消声室southe-shielded.Methods：我们记录了8个经验丰富的CI收件人和8个年轻的正常听力志愿者。所有受试者在4种情况下进行姿势图评估：（1）有声音睁眼，（2）有声音闭眼，（3）无声音睁眼，（4）无声音闭眼。听力正常者在有声和无声条件下，压力中心（COP）的平均中外侧位移无显著差异。在CI受者中，在无声条件下剥夺视觉线索后，COP显著移位到CI侧。结论：在CI受试者中，声音刺激改善了COP在中外侧方向的异常位移，在无回声条件下的姿势图研究证明，声音刺激改善了CI受试者的身体平衡功能。(C)2018国际临床神经生理学联合会。Elsevier B.

Objective: The relation between well-controlled auditory stimulation through cochlear implant (CI) and the body balance has been sparsely investigated. The purpose of this study was to evaluate the body balance function of CI patients with- and without-sound in anechoic sound-shielded room.Methods: We recorded 8 experienced CI recipients and 8 young normal-hearing volunteers. All subjects were assessed using posturography under 4 conditions: (1) eyes open with-sound, (2) eyes closed with-sound, (3) eyes open without-sound, and (4) eyes closed without-sound.Results: The total path length and the total area were significantly larger in the eyes closed condition than in the eyes open condition. In normal hearing subjects, the average displacement of center of pressure (COP) in the mediolateral direction under with-sound condition was not different from that under without-sound condition. In CI recipients, the COP significantly displaced to the CI side after the deprivation of visual cues in without-sound condition. This shift was eliminated in with-sound condition (significant interaction among sound condition, eye condition, and between-group factor).Conclusion: In CI subjects, sound stimulation improves the abnormal displacement of COP in the mediolateral direction.Significance: A posturographic study under an anechoic condition proved that sound stimulation improves body balance function in CI subjects.
