摘　　要：目的:探讨国际协作共济失调评估量表(ICARS)与共济失调等级量表(SARA)评估脊髓小脑性共济失调3型/M achado-Joseph病患者的相关因素。方法:应用ICARS与SARA对126例基因检测明确诊断为脊髓小脑性共济失调3型患者进行评估,分析ICARS评分、SARA评分与发病年龄、病程、CAG重复次数的相关性。结果:ICARS总评分(Y1)、SARA总评分(Y2)与病程(X2)呈正相关(r=0.586,P<0.05;r=0.643,P<0.05),回归方程分别为Y1=13.072+2.388X2(F=68.874,P<0.05),Y2=4.403+0.961X2(F=87.254,P<0.05)。ICARS总评分、SARA总评分与年龄的比值分别与CAG重复次数呈正相关(r=0.328,P<0.05;r=0.335,P<0.05)。ICARS各项评分、SARA各项评分与病程均呈正相关(r=0.257～0.589,P<0.05;r=0.432～0.623,P<0.05)。ICARS各项评分、SARA各项评分与年龄比值分别与CAG重复次数呈正相关(r=0.263～0.403,P<0.05;r=0.189～0.366,P<0.05)。ICARS总评分、SARA总评分均随着病情严重程度增加而增加。结论:ICARS与SARA评分量表均能够有效地反映共济失调患者的病情严重程度,研究者可根据实际需要选用合适的量表。Objective To investigate the related factors of international cooperative ataxia rating scale（ICARS） and scale for the assessment and rating of ataxia scores（SARA） in patients with spinocerebellar ataxia type 3/Machado-Joseph disease.Methods A total of 126 SCA3/MJD patients were assessed by ICARS and SARA.The relation between ICARS or SARA scores and age of onset,disease duration and CAG repeat size was analyzed.Results Either the total ICARS or the total SARA score was positively related with the disease duration（r=0.586,P0.05;r=0.643,P0.05）.Simple linear regression equations were： Y1（total ICARS score）=13.072＋2.388 X2（disease duration）（F=68.874,P0.05）;Y2（total SARA score）=4.403＋ 0.961 X2（disease duration）（F=87.254,P0.05）.Either age adjusted the total ICARS score or age adjusted the total SARA score was positively related with CAG repeat size（r=0.328,P0.05;r=0.335,P0.05）.Both the ICARS subscores and the SARA subscores were positively related with the disease duration（r=0.257-0.589,P0.05;r=0.432-0.623,P0.05）.Both age adjusted ICARS subscores and age adjusted SARA subscores were positively related with CAG repeat size（r=0.263-0.403,P0.05;r=0.189-0.366,P0.05）.Analysis of variance showed that the total ICARS score and the total SARA score increased with the disease stage.Conclusion ICARS and SARA are both reliable and effective scales in assessing the severity of ataxia in patients with SCA3/MJD,and researchers can choose the most suitable scale according to specific requirement.
