The Arm Activity Measure was developed to assess active and passive functions of the upper limb in people with unilateral paresis, but a Chinese version is not available and its psychometric properties have not been specifically tested in people with stroke. This study aimed to translate and culturally adapt the Chinese version of the Arm Activity Measure (ArmA-C) and establish its psychometric properties in people with chronic stroke.
The psychometric properties of ArmA-C were determined in 100 people with chronic stroke.
The ArmA-C had good test-retest reliability (intraclass correlation coefficients [ICC] = 0.87-0.93; quadratic weighted Kappa coefficients = 0.53-1.00). A floor effect was identified in section A of the ArmA-C. The content validity and internal consistency (Cronbach's alpha coefficients = 0.75-0.95) were good. The construct validity of the ArmA-C was supported by acceptable fit to the two-factor structure model and significant correlations with the Fugl-Meyer Assessment for Upper Extremity score, grip strength, the Wolf Motor Function Test score, the Trail Walking Test completion time, and the Oxford Participation and Activities Questionnaire scores.
The ArmA-C is reliable and valid for assessing active and passive functions in people with chronic stroke.
上肢活动量表旨在评估单侧轻瘫患者上肢的主动和被动功能，但尚无中文版，且其心理测量学特性尚未在中风患者中进行专门测试。本研究旨在翻译并进行文化调适上肢活动量表中文版（ArmA-C），并在慢性中风患者中确定其心理测量学特性。
对100例慢性中风患者测定ArmA-C的心理测量学特性。
ArmA-C具有良好的重测信度（组内相关系数[ICC]=0.87-0.93；二次加权Kappa系数=0.53-1.00）。在ArmA-C的A部分发现了地板效应。内容效度和内部一致性良好（Cronbach'sα系数=0.75-0.95）。ArmA-C的结构效度得到支持，其与双因素结构模型拟合良好，且与上肢Fugl-Meyer评估评分、握力、Wolf运动功能测试评分、步行轨迹测试完成时间以及牛津参与和活动问卷评分显著相关。
ArmA-C在评估慢性中风患者的主动和被动功能方面可靠且有效。
