This study evaluated the correlation between patient and clinician subjective voice analysis in a group of patients suffering from muscular tension dysphonia. This disease does not usually present with organic lesions, and voice analysis is crucial to evaluate it.
A retrospective study with 75 patients was performed. Correlation between grade, roughness, breathiness, asthenia and strain scale and voice handicap index-10 was analysed. Any possible influence of the type of muscular tension dysphonia on these two scales was studied.
There are only a few studies that correlate voice handicap index-10 and the grade, roughness, breathiness, asthenia and strain scale; however, none of them are specific for patients suffering from muscular tension dysphonia. A moderate correlation (r = 0.56) was found. No influence of muscular tension dysphonia type on voice handicap index-10 score was found, but muscular tension dysphonia type 4 had worse grade, roughness, breathiness, asthenia and strain scale scores than other muscular tension dysphonia types. This could be explained if muscular tension dysphonia type 4 is considered to be the most severe form of this disease.
The use of assessment scales based on the opinion of both the clinician and patient must be considered as complementary clinical tools in order to perform a complete assessment of dysphonia.
本研究评估了一组患有肌肉紧张性发声障碍患者的主观声音分析与临床医生主观声音分析之间的相关性。这种疾病通常不会出现器质性病变，因此声音分析对于评估该疾病至关重要。
对75例患者进行了一项回顾性研究。分析了等级、粗糙度、气息声、无力和紧张量表与嗓音障碍指数-10之间的相关性。研究了肌肉紧张性发声障碍类型对这两个量表的任何可能影响。
仅有少数研究将嗓音障碍指数-10与等级、粗糙度、气息声、无力和紧张量表相关联；然而，这些研究均未针对患有肌肉紧张性发声障碍的患者。发现两者存在中度相关性（r = 0.56）。未发现肌肉紧张性发声障碍类型对嗓音障碍指数-10评分有影响，但4型肌肉紧张性发声障碍的等级、粗糙度、气息声、无力和紧张量表评分比其他类型的肌肉紧张性发声障碍更差。如果将4型肌肉紧张性发声障碍视为该疾病最严重的形式，这一点或许可以得到解释。
基于临床医生和患者意见的评估量表的使用必须被视为辅助临床工具，以便对发声障碍进行全面评估。
