| Abstract (English): | The relation between the autonomic nervous system (ANS) and muscles of the vocal tract is of particular importance when considering the pathomechanism of a functional voice disorder. The aim of this study was to record electrophysiological indicators from the ANS as well as the tone of the external laryngeal muscle and test whether together they could point to an enhanced risk of primary functional voice disorder. The study material consisted of 81 people, 27 of whom were professional opera singers. None reported any voice complaints. The research comprised ENT and phoniatric examination, superficial electromyography (SEMG), and recording of physiological indicators (pulse rate, skin resistance). All subjects had a clear voice with no sign of vocal disability. Endoscopy revealed laryngeal hyperfunction in 26 people. SEMG revealed that the 26 had increased external laryngeal muscle tone during phonation, and this finding correlated with a change in certain electrophysiological indicators HRV, BVP, EDA. We conclude that anomalies in electrophysiological parameters in individuals with subclinical symptoms of functional voice disorder may be at risk of developing fully symptomatic hyperfunctional dysphonia in the future. Vocal training, which differentiates singers and non-singers, is known to have an effect on subclinical hyperfunctional dysphonia. By measuring indicators of hyperfunctional dysphonia, it may be possible to take remedial action before symptomatic dysphonia develops. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): | 背景：在考虑功能性嗓音障碍的病理机制时, 自主神经系统 (ANS) 与声带肌肉之间的关系尤为重要。 目的：本研究的目的是记录 ANS 的电生理指标以及喉外肌的紧张度, 并测试它们是否一起指示原发性功能性嗓音障碍的风险增加。 材料和方法：研究材料由 81 人组成, 其中 27 人是专业的歌剧演员。 没有人报告任何声音不适。 该研究包括耳鼻喉科和语音检查、表面肌电图 (SEMG) 和生理指标记录（脉搏率、皮肤阻）。 结果：所有受试者的声音都很清晰, 没有发声障碍的迹象。 内窥镜检查发现26 人喉功能亢进。 SEMG 显示 26 人的喉外肌张力在发声过程中增加, 这一发现与某些电生理指标HRV、BVP、EDA的变化相关。 结论：我们的结论是, 具功能性嗓音障碍亚临床症状者的电生理参数异常可能在未来有发展为完全症状性功能亢进性发音障碍的风险。 将歌手和非歌手分开的声乐训练, 已知对亚临床功能亢进性发音困难有作用。 意义：通过测量功能亢进性发声障碍的指标, 就有可能在出现症状性发声障碍之前采取补救措施。 [ABSTRACT FROM AUTHOR] |
