Bioelectrical parameters of two groups of external laryngeal muscles, viz. superior muscles pulling up and inferior muscles pulling down the thyroid cartilage, were measured. Hypokinetic dysphonia was indicated by 1.2-1.6-fold increase of the pulse amplitude of superior muscles and hyperkinetic dysphonia was evidenced by 1.4-2.0-fold increase of that of inferior muscles. When the amplitude was identical on differed by less than 1.2 times, mixed dysphonia was suspected. In healthy people, the pulse amplitude of inferior muscles exceeded that of superior muscles by 1.2-1.4 times. This approach helps to improve the accuracy and reliability of dysphonia diagnosis, to better understand mechanisms of the pathology, and to develop the most efficient methods of voice recovery. Altogether 60 patients and 30 normal subjects were examined.
对两组喉外肌的生物电参数进行了测量，即提拉甲状软骨的上方肌肉和下拉甲状软骨的下方肌肉。上方肌肉脉冲幅度增加1.2至1.6倍表明存在运动减退性发音障碍，下方肌肉脉冲幅度增加1.4至2.0倍则证明存在运动亢进性发音障碍。当幅度相同或相差小于1.2倍时，则怀疑为混合性发音障碍。在健康人中，下方肌肉的脉冲幅度比上方肌肉高1.2至1.4倍。这种方法有助于提高发音障碍诊断的准确性和可靠性，更好地理解病理机制，并开发最有效的嗓音恢复方法。总共检查了60名患者和30名正常受试者。
