Although there are articles and studies that associate postural changes with changes in vocal quality, to the best of our knowledge, this was the first study investigating the association between balance disorders and voice.
This study aimed to determine whether patients with balance disorders present any clinical, acoustic, or endoscopic vocal changes, and if the correction of balance impairments, such as through vestibular rehabilitation, lead to improvement in vocal quality.
This was a prospective cohort study that analyzed vocal differences (clinical, videoendostroboscopic, audio-perceptual, and acoustic vocal parameters) in a sample of 43 patients with vestibular dysfunction at three different time points (pre-treatment, post-treatment, and 3 months' post-treatment) diagnosed by videonystagmography with changes in computerized dynamic posturography who were treated with vestibular rehabilitation.
In pre-treatment, all of the patients presented supraglottic hyperfunction during videoendoscopic examination and abnormal values in the audio-perceptual scale. After treatment for balance disorders, there was a statistically significant improvement in some parameters of the videoendoscopic and audio-perceptual measures. These improvements were detected immediately after treatment and remained present until at least three months after treatment.
The results suggested that the treatment for balance disorders results in changes in posture and consequently in voice quality.
虽然有一些文章和研究将姿势变化与声音质量变化联系起来，但据我们所知，这是第一项研究平衡障碍与声音之间的关联。
本研究旨在确定平衡障碍患者是否存在任何临床、声学或内窥镜声音变化，以及平衡障碍的矫正（如通过前庭康复）是否会导致声音质量的改善。
这是一项前瞻性队列研究，分析了 43 名前庭功能障碍患者在三个不同时间点（治疗前、治疗后和治疗后 3 个月）的声音差异（临床、视频频闪喉镜、音频感知和声学嗓音参数），这些患者通过视频眼震图诊断，并通过计算机动态姿势描记术改变进行前庭康复治疗。
在治疗前，所有患者在视频频闪喉镜检查中均表现出声门上过度功能，音频感知量表中的值异常。在治疗平衡障碍后，视频频闪喉镜和音频感知测量的一些参数有统计学意义的改善。这些改善在治疗后立即出现，并至少持续到治疗后 3 个月。
结果表明，平衡障碍的治疗会导致姿势变化，从而导致声音质量变化。
