OBJECTIVE
Functional dysphonia can impair the language expression ability and adversely affect the career development of some patients. Therefore, an active exploration of effective treatment options is imperative. This study investigated the effect of Akson therapy on acoustic parameters in patients with functional dysphonia.
MATERIALS AND METHODS
In this retrospective analysis, 79 patients with functional dysphonia who received conventional voice correction training from June 2020 to June 2021 were included in the reference group (RG). Our hospital has implemented Akson therapy since July 2021. Correspondingly, 72 patients with functional dysphonia who underwent Akson therapy from July 2021 to July 2022 were enrolled in the observation group (OG). The acoustic parameters such as fundamental frequency (F0), jitter, shimmer, and normalized noise energy (NNE); the aerodynamic parameters including maximum phonation time (MPT), mean airflow rate (MFR), and Voice Handicap Index-10 (VHI-10) score; and the Grade, Roughness, Breathiness, Asthenia, and Strain scale (GRBAS) score were measured before and after treatment and compared between the two groups.
RESULTS
The F0, jitter, shimmer, NNE, MPT, and MFR values as well as the VHI-10 score and the grade (G), roughness (R), and breathiness (B) scores on the GRBAS did not significantly differ between the two groups before treatment (P > 0.05). However, significantly lower F0, jitter, shimmer, NNE, and MFR values and higher MPT levels were found in the OG compared to the RG after treatment (P < 0.001). Furthermore, the VHI-10 score and the G, R, and B scores were significantly lower in the OG than in the RG after treatment (P < 0.001), whereas the asthenia (A) and strain (S) scores remained at 0 before and after treatment.
CONCLUSION
Akson therapy can improve the acoustic parameters of patients with functional dysphonia to a certain extent, indicating its potential application value.
目的
功能性嗓音障碍可能会损害患者的语言表达能力，并对其职业发展产生不利影响。因此，积极探索有效的治疗方案至关重要。本研究旨在探讨 Akson 疗法对功能性嗓音障碍患者声学参数的影响。
材料和方法
本回顾性分析纳入了 79 例 2020 年 6 月至 2021 年 6 月接受常规嗓音矫正训练的功能性嗓音障碍患者作为参考组（RG）。我院自 2021 年 7 月起开始实施 Akson 疗法，同期纳入 72 例接受 Akson 疗法的功能性嗓音障碍患者作为观察组（OG）。比较两组患者治疗前后的声学参数[基频（F0）、抖动、声扰、噪声能量比（NNE）]、空气动力学参数[最长发声时间（MPT）、平均气流率（MFR）和嗓音障碍指数-10（VHI-10）评分]、嗓音障碍程度分级、粗糙度、粗糙声、气息声、嘶哑声和紧张度（GRBAS）评分。
结果
治疗前两组患者的 F0、抖动、声扰、NNE、MPT 和 MFR 水平以及 VHI-10 评分和 GRBAS 中的分级（G）、粗糙度（R）和气息声（B）评分均无显著差异（P > 0.05）。治疗后，OG 患者的 F0、抖动、声扰、NNE 和 MFR 水平均显著低于 RG 患者，MPT 水平显著高于 RG 患者（P < 0.001）。治疗后，OG 患者的 VHI-10 评分和 G、R 和 B 评分均显著低于 RG 患者（P < 0.001），而乏力（A）和紧张度（S）评分在治疗前后均为 0。
结论
Akson 疗法可在一定程度上改善功能性嗓音障碍患者的声学参数，具有一定的应用价值。
