Abstract

Purpose: Neurogenic speech and language disorders-such as acquired apraxia of speech (AOS) and aphasia with phonemic paraphasia (APP)-are often misdiagnosed due to similarities in clinical presentation. Word syllable duration (WSD)-a measure of average syllable length in multisyllabic words-serves as a proxy for speech rate, which is an important and arguably more objective clinical characteristic of AOS and APP. This study reports stability of WSD over time for speakers with AOS (and aphasia).

Method: Twenty-nine participants with AOS and aphasia (11 women and 18 men, M_age = 53.5 years, SD = 13.3) repeated 30 multisyllabic words (of three-, four-, and five-syllable lengths) on three occasions across 4 weeks. WSDs were calculated for each word and then averaged across each list (i.e., word length), as well as across combined lists (i.e., all 30 words) to yield four WSDs for each participant at each time point. Stability over time was calculated using Friedman's test for the group and using Spearman's rho for the individual level. Effects of time and word length were examined using robust mixed-effects linear regression.

Results: Friedman's tests and correlations indicated no significant difference in WSDs across sampling occasions for each word length separately or combined. WSD correlated positively with AOS severity and negatively with intelligibility but was not correlated with aphasia severity. Regression analyses confirmed WSD to be stable over time, while WSD calculated from only five tokens (i.e., WSD-5) was less stable over time.

Conclusions: Results indicate that WSD can be a stable measure over time, at the individual and group level, providing support for its use in diagnosis and/or as an outcome measure, both clinically and for research. In general, WSD outperformed WSD-5, suggesting that it may be better to calculate WSD from more than five tokens. Stability of WSD in other populations and suitability for differential diagnosis need to be determined. Currently, differentiating disorders by speaking rate, alone, is not recommended.

后天性语言障碍患者单词音节持续时间的稳定性。

目的：由于临床表现相似，神经源性言语和语言障碍（如获得性言语障碍（AOS）和音位偏瘫性失语症（APP））经常被误诊。单词音节持续时间（WSD）是对多音节单词中平均音节长度的测量，可作为语速的替代指标，而语速是 AOS 和 APP 的一个重要且可以说是更客观的临床特征。本研究报告了 AOS（和失语症）患者 WSD 随时间变化的稳定性：方法：29 名患有 AOS 和失语症的参与者（11 名女性和 18 名男性，年龄 = 53.5 岁，SD = 13.3）在 4 周内三次重复 30 个多音节词（长度分别为三音节、四音节和五音节）。计算每个单词的 WSD，然后对每个列表（即单词长度）以及组合列表（即所有 30 个单词）进行平均，得出每个时间点每位参与者的四个 WSD。在计算随时间变化的稳定性时，小组采用弗里德曼检验，个人采用斯皮尔曼rho检验。使用稳健的混合效应线性回归检验了时间和单词长度的影响：弗里德曼检验和相关性表明，在不同的取样场合，每种词长的 WSD 没有明显差异。WSD 与 AOS 严重程度呈正相关，与可懂度呈负相关，但与失语症严重程度无关。回归分析证实 WSD 随时间的推移而稳定，而仅根据五个词块计算的 WSD（即 WSD-5）随时间的推移稳定性较差：结论：研究结果表明，在个人和群体水平上，WSD是一种长期稳定的测量指标，这为其在临床和研究中用于诊断和/或作为结果测量指标提供了支持。总的来说，WSD 的表现优于 WSD-5，这表明用五个以上的标记来计算 WSD 可能会更好。需要确定 WSD 在其他人群中的稳定性以及是否适合用于鉴别诊断。目前，不建议仅通过说话速度来区分疾病。补充材料：https://doi.org/10.23641/asha.25438735。

期刊介绍： Mission: JSLHR publishes peer-reviewed research and other scholarly articles on the normal and disordered processes in speech, language, hearing, and related areas such as cognition, oral-motor function, and swallowing. The journal is an international outlet for both basic research on communication processes and clinical research pertaining to screening, diagnosis, and management of communication disorders as well as the etiologies and characteristics of these disorders. JSLHR seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of communication sciences and disorders, including speech production and perception; anatomy and physiology of speech and voice; genetics, biomechanics, and other basic sciences pertaining to human communication; mastication and swallowing; speech disorders; voice disorders; development of speech, language, or hearing in children; normal language processes; language disorders; disorders of hearing and balance; psychoacoustics; and anatomy and physiology of hearing.
