Muscle tension dysphonia (MTD) is a functional dysphonia, which appears with an excessive tension in the intrinsic and extrinsic laryngeal musculatures. MTD can affect voice quality and quality of life. The purpose of the present study was to assess the effectiveness of vocal function exercises (VFEs) on perceptual and self-assessment ratings in a group of 15 subjects with MTD.
The study comprised 15 subjects with MTD (8 men and 7 women, mean age 39.8 years, standard deviation 10.6, age range 24-62 years). All participants were native Persian speakers who underwent a 6-week course of VFEs. The Voice Handicap Index (VHI) (the self-assessment scale) and Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scale (perceptual rating of voice quality) were used to compare pre- and post-VFEs.
GRBAS data of patients before and after VFEs were compared using Wilcoxon signed-rank test, and VHI data of patients pre- and post-VFEs were compared using Student paired t test. These perceptual parameters showed a statistically significant improvement in subjects with MTD after voice therapy (significant at P < 0.05 () and P < 0.004 (**)). Also results indicated statistically noticeable reduction in the mean VHI scores across subjects with MTD (significant at P < 0.05 () and P < 0.004 (**)).
Significant improvement after therapy for participants has been observed by the aid of auditory-perceptual ratings of voice quality (with the GRBAS scale) and the patient's self-assessment ratings measurements (with the VHI). As a result, the data provide evidence regarding the efficacy of VFEs in the treatment of patients with MTD.
肌肉紧张性发音障碍（MTD）是一种功能性发音障碍，表现为喉内肌和喉外肌过度紧张。MTD会影响嗓音质量和生活质量。本研究的目的是评估嗓音功能锻炼（VFE）对15名MTD患者的感知评分和自我评估评分的有效性。
该研究包括15名MTD患者（8名男性和7名女性，平均年龄39.8岁，标准差10.6，年龄范围24 - 62岁）。所有参与者均为以波斯语为母语的人，他们接受了为期6周的VFE课程。使用嗓音障碍指数（VHI）（自我评估量表）和等级、粗糙度、气息声、无力、紧张（GRBAS）量表（嗓音质量的感知评分）来比较VFE前后的情况。
使用Wilcoxon符号秩检验比较患者VFE前后的GRBAS数据，使用学生配对t检验比较患者VFE前后的VHI数据。这些感知参数显示，嗓音治疗后MTD患者有统计学上的显著改善（P < 0.05（）和P < 0.004（**）时具有显著性）。结果还表明，MTD患者的平均VHI评分在统计学上有显著降低（P < 0.05（）和P < 0.004（**）时具有显著性）。
通过嗓音质量的听觉感知评分（使用GRBAS量表）和患者的自我评估评分测量（使用VHI），观察到参与者治疗后有显著改善。因此，这些数据为VFE治疗MTD患者的疗效提供了证据。
