Inter-Tester Reliability and Agreement of the Cumulated Ambulation Score in Stroke patients: The InTRO-CAS-stroke study To examine the inter-tester reliability of the total Cumulated Ambulation Score (CAS) and the three activities of the CAS, and to define limits for the smallest change in basic mobility that indicates a real change in patients with stroke. An intertester reliability study. Setting: Participants: 60 participants from a specialized stroke unit with a mean age of 69.10 ±13.23 years. The CAS describes a patient's independency in three activities – (1) getting in and out of bed, (2) sit to stand from a chair, and (3) walking ability and was assessed by two independent physiotherapists at median day 3 poststroke. Each activity was assessed on a three-point ordinal scale from 0 (not able to) to 2 (independent). The cumulated score for each activity provides a total CAS from 0 to 6, with 6 indicating independent basic mobility. Relative and absolute reliability was evaluated using weighted kappa, the standard error of measurement (SEM) and minimal detectable change (MDC). The weighted kappa for the total CAS score was 0.816 and ranged from 0.733 to 0.904 for the 3 CAS activities. The SEM and the MDC of the total CAS was 0.37 and 1.03 respectively. The intertester reliability of the CAS is almost perfect, and a change of 1 CAS point for the total CAS indicates a real change in basic mobility, at group level and for an individual patient with stroke NCT05601089

亚急性中风累积行走评分的测试者间可靠性和一致性：InTRO-CAS-中风研究

中风患者累积步行评分的测试者间可靠性和一致性：InTRO-CAS-中风研究 检查总累积步行评分 (CAS) 和 CAS 的三项活动的测试者间可靠性，并定义限值基本活动能力的最小变化表明中风患者的真正变化。测试者间的可靠性研究。设置：参与者：来自专门卒中科室的 60 名参与者，平均年龄为 69.10 ±13.23 岁。CAS 描述了患者在三项活动中的独立性 - (1) 上下床，(2) 从椅子上坐站起来，以及 (3) 行走能力，并由两名独立的物理治疗师在中风后第 3 天的中位时间进行评估。每项活动均按照从 0（不能）到 2（独立）的三点顺序等级进行评估。每项活动的累积分数提供了从 0 到 6 的 CAS 总分，其中 6 表示独立的基本活动能力。使用加权卡伯、测量标准误差 (SEM) 和最小可检测变化 (MDC) 评估相对和绝对可靠性。3 项 CAS 活动的 CAS 总得分的加权 kappa 为 0.816，范围为 0.733 至 0.904。总CAS的SEM和MDC分别为0.37和1.03。CAS 的测试者间可靠性几乎是完美的，总 CAS 变化 1 个 CAS 点表明团体层面和中风患者个体的基本活动能力发生了真正的变化 NCT05601089
