背景与目的：上肢动作研究试验（ARAT）是一种用于评估上肢皮质损伤后功能恢复的方法。本研究旨在验证脑卒中患者ARAT量表的信度和效度。出于评估者间研究的目的，由3名经验丰富的评估者在3天内对每名患者进行ARAT。有效性进行了评估，通过比较患者的评分ARAT与其他有效的测量评估上肢运动障碍和disability.Results：类内相关系数（ICC）的总得分为0.98，表示非常高的评分员间的可靠性。ARAT评分与运动评定量表上肢部分评分、运动指数手臂分评分和改良运动评定量表上肢运动评分密切相关Pearson相关系数分别为0.96、0.87和0.94。结论：本研究的初步结果支持了ARAT在脑卒中患者臂手功能恢复评估中的价值。
Background and purpose: the Action Research arm test (ARAT) was constructed for assessing recovery of upper extremity function after cortical injury. The objective of the study was to verify the inter-rater reliability and validity of the ARAT in stroke patients.Methods: 50 stroke patients participated in the study. For the purpose of inter-rater study the ARAT was administered by three experienced raters on each patient within a 3-day period. Validity was assessed by comparing the patients' scores on the ARAT with those obtained for the other well-validated measurements evaluating upper extremity motor impairment and disability.Results: intra-class correlation coefficient (ICC) for the total score was 0.98 indicating very high inter-rater reliability. ICCs were also very high in each of the subscales, The score of the ARAT was closely correlated with that of the upper extremity part of the motor assessment scale, the arm sub-score of the motricity index and the upper extremity movements of the modified motor assessment chart (Pearson r = 0.96, 0.87 and 0.94, respectively).Conclusion: the preliminary results of this study support the value of the ARAT for measuring recovery of arm-hand function in stroke patients.
