我们评估了 100 分国际合作共济失调评定量表 (ICARS) 的评分者间可靠性。三位神经科医生对 22 名患有遗传性共济失调（脊髓小脑共济失调 [SCA] 1 型：11 名；SCA 2 型：1 名；弗里德赖希共济失调：10 名）受试者和 4 名对照受试者的录像 ICARS 检查进行了独立评分。对照者的实时 ICARS 评估分数范围为 0 至 7，共济失调受试者的分数范围为 11 至 74（临床上坐轮椅的影响非常轻微）。总分的评估者间相关性非常高（Kendall 的 ω 0.994，95% 置信区间，0.988–0.997），每个分量分项得分从高到非常高（言语为 0.791，姿势/步态为 0.994）。所有相关性均显着（P < 0.00001）。即使没有事先进行观察者标准化，ICARS 也表现出非常高的评估者间可靠性，并且对从非常轻微到严重的一系列共济失调严重程度敏感。 © 2003 运动障碍协会
We assessed the inter‐rater reliability of the 100‐point International Cooperative Ataxia Rating Scale (ICARS). Three neurologists independently rated videotaped ICARS examinations of 22 subjects with genetically determined ataxias (spinocerebellar ataxia [SCA] Type 1 in 11; SCA Type 2 in 1; Friedreich's ataxia in 10) and 4 controls. Scores on live ICARS assessment had ranged from 0 to 7 for controls and 11 to 74 for ataxic subjects (clinically very mildly affected to wheelchair‐bound). Inter‐rater correlation was very high for the total score (Kendall's ω 0.994, 95% confidence interval, 0.988–0.997), and high to very high for each component subscore (0.791 for speech to 0.994 for posture/gait). All correlations were significant at P < 0.00001. The ICARS exhibits very high inter‐rater reliability even without prior observer standardisation and is sensitive to a range of ataxia severities from very mild to severe. © 2003 Movement Disorder Society
