本研究的目的是评估Fahn-Tolosa-Marin震颤评定量表（TRS）在特发性震颤（ET）中的判据和判据内的可靠性。ET的正确治疗取决于对严重程度、功能丧失和与震颤相关的残疾的正确评估。制作了17名被试用TRS评估ET的录像带，并将其发送给59名评分者。一旦评分者归还录像带并完成计分表，他们就会收到另一盘录像带，其中同样的录音以不同的顺序呈现。在互判器可靠性评估中，7种震颤型复合材料的修正Kappa统计量在第一卷录像带中为0.10 ~ 0.65，在第二卷录像带中为0.17 ~ 0.62。TRS的A部分项目（不同身体部位的震颤震级）比B部分项目（书写和绘图中的震颤）的判读信度更高。斯皮尔曼相关系数平均为0.87，表明两盘录像带的一致性非常好，但A部分的相关性比b部分的要好一些。当同一位评分者对一个病人进行反复的震颤测量时，尤其是在判断笔迹和绘画的震颤时，效果最好。对评分员进行TRS使用方面的培训将有助于标准化判断。(c) 2007年运动障碍协会。
The purpose of this study was to evaluate interrater and intrarater reliability of the Fahn-Tolosa-Marin Tremor Rating Scale (TRS) in essential tremor (ET). Proper treatment of ET is contingent upon correct assessment of the severity, loss of function, and disability related to tremor. Videotape recordings of 17 subjects with ET evaluated with the TRS were produced and sent to 59 raters. Once the raters returned the videotape and completed the score sheet, they were mailed a second tape with the same recordings presented in a different order. In the interrater reliability evaluation, modified Kappa statistics for seven tremor type composites ranged from 0.10 to 0.65 in the first videotape and 0.17 to 0.62 in the second videotape. Interrater reliabilities were greater for Part A items (magnitude of tremor in different body parts) than for Part B items (tremor in writing and drawings) of the TRS. The average Spearman correlation was 0.87, indicating very good consistency between the two videotapes, but correlations for Part A were somewhat better than for Part B. It is best when the same rater performs repeated measures of tremor on a patient, particularly when judging tremor in handwriting and drawings. Training of raters on use of the TRS would help standardize judgement. (c) 2007 Movement Disorder Society.
