A previous study revealed that reliable assessment of dysarthria was feasible. However, that study also revealed a number of system limitations and suggested that technological enhancements and improvements in study design and clinical assessment protocols were needed before validity and reliability of assessment of dysarthria via telerehabilitation could be confirmed. In the current study, improvements in technology, study design, and clinical assessment protocols were implemented in order to re-examine the validity and reliability of assessing and diagnosing dysarthria via the telerehabilitation medium. The aim of this study was to explore the validity and reliability of assessing dysarthria using both formal standardized and informal assessments via a purpose-built telerehabilitation system. Twenty-four participants with an acquired dysarthria were assessed simultaneously via telerehabilitation and face-to-face (FTF) on a battery of assessments. A custom-built telerehabilitation system enabled real-time telerehabilitation assessment over a 128 Kbps Internet connection. Data analysis included an analysis of strength of agreement between the two methods using percentage agreement and weighted ? statistics. Inter-rater and intrarater reliability were also examined for both the FTF and telerehabilitation-led assessments. Good strength of agreement was found between the FTF and telerehabilitation assessment methods. High intrarater and inter-rater reliability within both the FTF and telerehabilitation assessment methods supported these findings. Participants reported high overall satisfaction in the telerehabilitatin environment. This study describes the improvements made to the telerehabilitation system reported previously and confirms that valid and reliable assessment of dysarthria using both standardized and informal assessments over the Internet is possible using this system.
先前的研究表明，对构音障碍进行可靠评估是可行的。然而，该研究还揭示了一些系统限制，并表明在通过远程康复技术评估构音障碍的有效性和可靠性得到确认之前，需要对技术进行改进并改善研究设计和临床评估方案。在当前的研究中，对技术、研究设计和临床评估方案进行了改进，以重新检验通过远程康复技术评估构音障碍的有效性和可靠性。本研究的目的是通过专门构建的远程康复系统，探索使用正式标准化和非正式评估来评估构音障碍的有效性和可靠性。24 名获得性构音障碍患者通过远程康复和面对面（FTF）同时接受一系列评估。定制的远程康复系统可通过 128 Kbps 的 Internet 连接实现实时远程康复评估。数据分析包括使用百分比一致性和加权? 统计分析两种方法之间的一致性强度。还对 FTF 和远程康复引导的评估进行了组内和组间可靠性检查。FTF 和远程康复评估方法之间具有良好的一致性。FTF 和远程康复评估方法中的高组内和组间可靠性支持了这些发现。参与者对远程康复环境的总体满意度较高。本研究描述了对先前报告的远程康复系统进行的改进，并证实使用该系统通过互联网进行的标准化和非标准化评估可以对构音障碍进行有效和可靠的评估。
