Balance control is based on multisensory interaction. In addition to vestibular, proprioceptive and visual information, it seems that auditory input also plays an important role.
The aim of the study was to investigate the effect of hearing on vestibulospinal coordination and to obtain deeper knowledge about mechanisms of audiovestibular interaction.
In normal hearing, healthy subjects who performed the Unterberger (Fukuda) stepping test with and without frontal presentation of noise, the distance of displacement, the angle of displacement and the angle of rotation were measured by means of ultrasound based cranio-corpo-graphy (CCG). Additionally, subjective estimation of the effect of auditory input was compared to objective test results.
In the noise condition, there was a significant improvement in the distance of displacement (mean with noise 66.9 cm ± 33.5 standard deviation, SD, mean without noise 77.0 cm ± 32.7 SD, p < 0.001) and in the angle of rotation (mean with noise 14.2° ± 10.1 SD, mean without noise 28.3° ± 20.2 SD, p < 0.001), while no difference was found within the conditions regarding the angle of displacement (mean with noise 29.1° ± 33.5 SD, mean without noise 30.0° ± 34.0 SD, p = 0.641). Side-specific analysis revealed a positive correlation between angle of displacement and angle of rotation in the condition without noise (Spearman r = 0.441, p < 0.001). The rate of agreement between subjective estimation of noise influence and objective test results ranged between only 43% and 63%, depending on the question and endpoint.
Hearing had a clearly beneficial effect of auditory inputs on vestibulospinal coordination, especially for distance of displacement and angle of rotation.
平衡控制基于多感官交互。除了前庭、本体感觉和视觉信息外，听觉输入似乎也起着重要作用。
本研究旨在调查听力对前庭脊髓协调的影响，并深入了解听觉前庭交互作用的机制。
在听力正常的健康受试者中，通过基于超声的颅体摄影术（CCG）测量其在有和无前额噪声呈现的情况下进行昂特伯格（福田）踏步试验时的位移距离、位移角度和旋转角度。此外，将听觉输入效果的主观估计与客观测试结果进行比较。
在有噪声的情况下，位移距离（有噪声时平均值为66.9厘米±33.5标准差，无噪声时平均值为77.0厘米±32.7标准差，p<0.001）和旋转角度（有噪声时平均值为14.2°±10.1标准差，无噪声时平均值为28.3°±20.2标准差，p<0.001）有显著改善，而在有和无噪声条件下位移角度方面未发现差异（有噪声时平均值为29.1°±33.5标准差，无噪声时平均值为30.0°±34.0标准差，p = 0.641）。特定侧别分析显示，在无噪声条件下，位移角度与旋转角度之间存在正相关（斯皮尔曼r = 0.441，p<0.001）。根据问题和终点的不同，噪声影响的主观估计与客观测试结果之间的一致率仅在43%至63%之间。
听力对前庭脊髓协调具有明显有益的听觉输入效应，尤其是在位移距离和旋转角度方面。
