The Unified Multiple System Atrophy Rating Scale (UMSARS) was developed to provide a surrogate measure of disease progression in multiple system atrophy. In the present study, the intrarater agreement of the motor examination part of the UMSARS was determined.
All patients were first examined face to face, while being video-recorded, by two senior and two junior investigators. The patients' videotaped examinations were reevaluated after 3 months. Intrarater reliability for each item was analyzed by kappa statistics.
Overall weighted kappa (κ) values were at least substantial or excellent for all UMSARS motor examination items, except for ocular motor dysfunction, which showed only moderate intrarater agreement. Intrarater reliability was comparable between senior and junior raters, with all κ differences being ≤ 0.22.
The motor examination part of the UMSARS was found to have satisfactory intrarater reliability in the present cohort.
统一多系统萎缩评定量表（UMSARS）旨在提供一种衡量多系统萎缩疾病进展的替代指标。本研究旨在确定 UMSARS 运动检查部分的内部一致性。
所有患者均由两位高级和两位初级研究人员进行面对面检查，并录像。患者的录像检查在 3 个月后进行重新评估。采用 Kappa 统计分析各项目的内部一致性。
除眼运动功能障碍外，UMSARS 运动检查的所有项目的整体加权 Kappa（κ）值均为显著或优秀，而眼运动功能障碍的内部一致性仅为中度。高级和初级评分者之间的内部一致性具有可比性，所有 κ 差异均≤0.22。
本研究队列中，UMSARS 的运动检查部分具有令人满意的内部一致性。
