To evaluate the influence of auditory cues on postural sway in normal-hearing (NH) individuals, hearing-impaired individuals with vestibular impairment (HIVL), or hearing-impaired (HI) individuals without vestibular impairment.
Thirty-two participants received a hearing and a vestibular evaluation (vHIT, oVEMP, cVEMP) and then were separated in to three groups (NH, HI, HIVL). All participants had to stand on a force platform in four postural conditions (A: EO/firm, B: EC/firm, C: EO/Foam, D: EC/Foam) under two auditory conditions, with or without auditory cues.
Results revealed that first, there was a significant difference between HIVL and both HI and NH groups in conditions C and D without auditory cues. Second, greater improvement for HIVL compared to NH and HI groups in condition C and D was observed with auditory cues. Finally, somatosensory reliance significantly decreased for the HIVL participants using hearing aids compared to NH and HI.
Our results suggest that hearing aids benefit for postural control may be modulated by vestibular function.
评估听觉提示对正常听力（NH）个体、伴有前庭功能障碍的听力障碍（HIVL）个体或不伴有前庭功能障碍的听力障碍（HI）个体的姿势摆动的影响。
32 名参与者接受了听力和前庭评估（vHIT、oVEMP、cVEMP），然后分为三组（NH、HI、HIVL）。所有参与者都必须在四个姿势条件下（A：EO/坚固，B：EC/坚固，C：EO/泡沫，D：EC/泡沫）站在力平台上，在两种听觉条件下，有无听觉提示。
结果表明，首先，在没有听觉提示的情况下，HIVL 与 HI 和 NH 组在条件 C 和 D 之间存在显著差异。其次，与 NH 和 HI 组相比，HIVL 组在有听觉提示的情况下，在 C 和 D 条件下的改善更大。最后，与 NH 和 HI 组相比，使用助听器的 HIVL 参与者的躯体感觉依赖性显著降低。
我们的结果表明，听觉提示对姿势控制的益处可能受到前庭功能的调节。
