The neurological causes of vocal fold paralyses have been well documented. However, the effect of these disorders on laryngeal vibration is not well understood. A theoretical four-mass model of the larynx, based on the work of Ishizaka and Isshiki (1976) and Koizumi, Taniguchi, and Hiromitsu (1987), was developed and adapted to simulate laryngeal biomechanical behavior. The model was used to evaluate various states of asymmetric laryngeal vibration. Input parameters that relate observed laryngeal function and model simulation were developed. Laryngeal paralyses were simulated by their predicted effect on these parameters. Simulations were compared with available data on glottal vibration in laryngeal paralyses. Complex modes of vibration were seen with certain combinations of asymmetrical lower mass stiffness and initial glottal gap.
声带麻痹的神经学原因已有充分记载。然而，这些疾病对喉部振动的影响尚未得到充分了解。基于石坂和石志木（1976年）以及小泉、谷口和宏光（1987年）的研究成果，开发了一种理论性的喉部四质量模型，并对其进行调整以模拟喉部生物力学行为。该模型用于评估不对称喉部振动的各种状态。开发了将观察到的喉部功能与模型模拟相关联的输入参数。通过预测声带麻痹对这些参数的影响来模拟声带麻痹。将模拟结果与喉部麻痹时声门振动的现有数据进行了比较。在不对称的较低质量刚度和初始声门间隙的某些组合下，可以看到复杂的振动模式。
