生物组织的无源电特性，称为组织生物阻抗，与潜在的组织生理学有关。这些测量尚未被探索作为通过检测声带病理来评估声带组织健康的方法，这需要探索健康组织和病理组织之间的差异以及表示和分析组织阻抗的方法（这激发了这项工作）。目的探讨声带内收、外展、发声/e/和发声/ah/4种状态下颈部组织的Cole阻抗模型参数的差异。方法组织生物阻抗是从健康的年轻人（N= 10）在四个声带状态下收集的，平均数据集减少到他们的科尔阻抗模型表示（R∞，R 1，C，α）使用粒子群优化方法。主要结果Cole阻抗模型很好地代表了收集的生物阻抗数据集，但在四个声带活动的平均局部生物阻抗数据集的Cole模型参数中没有观察到统计学显著差异。平均电组织特性可能对声带活动的变化不敏感。因此，局部组织生物阻抗可能是一种替代技术，以评估声带组织的健康，不需要发声。
The passive electrical properties of a biological tissue, referred to as the tissue bioimpedance, are related to the underlying tissue physiology. These measures have not been explored as a method to assess the health of vocal fold tissues by detecting vocal fold pathologies, which requires exploring differences between healthy and pathological tissues as well as methods to represent and analyze tissue impedances (which motivates this work). Objective To determine if there are statistically significant differences in Cole-impedance model parameters that represent averaged bioimpedance measurements of localized neck tissues during four vocal folds states (adducted, abducted, voicing/e/, and voicing/ah/). Approach Tissue bioimpedance was collected from healthy young adults (N= 10) in four vocal fold states with averaged datasets reduced to their Cole-impedance model representations (R∞, R 1, C, α) using a particle swarm optimization approach. Main result The Cole-impedance model does well represent the collected bioimpedance datasets, but no statistically significant differences in the identified Cole-model parameters of the averaged localized bioimpedance datasets across four vocal folds activities were observed. Significance Averaged electrical tissue properties may not be sensitive to variations from vocal folds activity. Therefore, localized tissue bioimpedance may be an alternative technique to assess vocal fold tissue health that does not require phonation.
