Abstract

Introduction

The Scale for Assessment and Rating of Ataxia (SARA) is a widely used clinical rating scale in ataxia. Remote video assessments of SARA examinations are increasingly used to reduce variability through centralized ratings. Remote video assessments have a high agreement with in-person ratings, but the intra- and inter-rater reliability of remote video ratings has not been examined. In this study, we compared the performance of live versus video SARA ratings and evaluated intra- and inter-rater reliability of SARA ratings via video review in patients with spinocerebellar ataxia (SCA) type 1, 2, 3, and 6.

Methods

We calculated the Bland-Altman analysis for average measures to assess the agreement between live and video ratings and the Intraclass Correlation Coefficient (ICC) for intra- and inter-rater reliability of video ratings.

Results

In all 15 participants, we found high agreement between live and video for all SARA items, with less than 0.5 point overestimation of video compared to live SARA total score, and excellent intra- and inter-rater reliability for the SARA total score rated by video revision, with an ICC of 0.98 and 0.95, respectively.

Conclusions

Our study highlights the ability to adopt SARA video ratings in clinical practice and research.

共济失调评定量表远程视频评分的可靠性。

简介：共济失调评定量表（SARA）是临床上广泛使用的共济失调评定量表。SARA检查的远程视频评估越来越多地用于通过集中评分来减少可变性。远程视频评价与现场评价具有较高的一致性，但远程视频评价的内部和内部可靠性尚未得到检验。在这项研究中，我们比较了现场SARA评分与视频SARA评分的表现，并通过视频回顾评估了脊髓小脑性共济失调（SCA） 1、2、3和6型患者SARA评分的内部和内部可靠性。方法：我们计算了Bland-Altman分析的平均措施，以评估直播和视频评级之间的一致性，以及视频评级内部和内部可靠性的类内相关系数（ICC）。结果：在所有15名参与者中，我们发现所有SARA项目的现场和视频之间的一致性很高，与现场SARA总分相比，视频的高估不到0.5点，并且通过视频修订评定的SARA总分的内部和内部可靠性非常好，ICC分别为0.98和0.95。结论：我们的研究突出了SARA视频评分在临床实践和研究中的应用能力。
