Maximum performance tests examine upper limits of speech motor performance, as used by speech-language pathologists in dysarthria assessment protocols. The Radboud Dysarthria Assessment includes maximum repetition rate, maximum phonation time, fundamental frequency range and maximum phonation volume to assist in detecting pathological performance. This study aims to obtain reference values for each of these tests.
A group of 224 healthy Dutch adults aged 18-80 years performed the maximum performance tests. Age, sex, body height, smoking habit, and profession were registered. Using multivariable linear regression, a wide range of models was tested to examine the relationship between these person characteristics and speech performance. The likelihood ratio was used to test the goodness of fit to the data.
Above 60 years of age, maximum repetition rate, fundamental frequency range and maximum phonation volume were all negatively affected by age. Below 60 years, only women showed effects of age on fundamental frequency range (increase) and maximum phonation volume (decrease). Maximum phonation time was primarily related to body height (increase).
This study presents reference values of four maximum performance tests for comparing the performance of dysarthric patients with non-pathological performance. Age was identified as most important factor influencing maximum speech performance.
最大性能测试用于检查言语运动性能的上限，言语病理学家在构音障碍评估方案中会用到。拉德堡德构音障碍评估包括最大重复率、最大发声时间、基频范围和最大发声音量，以协助检测病理表现。本研究旨在获取这些测试各自的参考值。
一组224名年龄在18至80岁之间的健康荷兰成年人进行了最大性能测试。记录了年龄、性别、身高、吸烟习惯和职业。使用多变量线性回归，测试了一系列模型，以检查这些个体特征与言语表现之间的关系。似然比用于检验数据的拟合优度。
60岁以上，最大重复率、基频范围和最大发声音量均受到年龄的负面影响。60岁以下，只有女性的年龄对基频范围（增加）和最大发声音量（降低）有影响。最大发声时间主要与身高有关（增加）。
本研究给出了四项最大性能测试的参考值，用于比较构音障碍患者与非病理表现者的表现。年龄被确定为影响最大言语表现的最重要因素。
