To validate the Familiar Tools Use Test (FTT) of the Diagnostic Instrument for Limb Apraxia-Short Version in Chinese stroke patients.
Participants were conveniently enrolled from a neurology ward in a tertiary hospital in Guangzhou, China, between April 2023 and September 2023. Internal consistency, test-retest reliability, inter-rater reliability, dimensionality, convergent validity, and divergent validity were examined.
In total, 110 ischemic stroke patients were included. The FTT demonstrated satisfactory internal consistency (Cronbach's α = 0.70-0.75), test-retest reliability (ICC 0.88-0.99, 95%CI), and inter-rater reliability (Kappa coefficients ranging from 0.83 to 1.00, 0.001). Exploratory factor analysis extracted one common factor for tool selection and two common factors for action execution. There were mild to moderate correlations between the scores of the FTT scales and the MoCA ( ranged from 0.37 to 0.50), indicating satisfactory convergent and divergent validity. The moderate correlations between the scores of the FTT scales and the PTU ( ranged from 0.49 to 0.51), indicating satisfactory concurrent validity. The prevalence of limb apraxia in patients with left brain damage when selecting, producing, and executing familiar tools were 14.9, 8.5, and 8.5%, respectively. While, the prevalence of apraxia during similar tasks in those with right brain damage were 3.0, 0, and 0%, respectively.
The FTT was reliable and valid for assessing limb apraxia among Chinese ischemic stroke patients.
验证中文版肢体失用症诊断工具简版中的常用工具使用测试（FTT）在中风患者中的有效性。
2023年4月至2023年9月期间，在中国广州一家三级医院的神经内科病房方便地招募了参与者。检查了内部一致性、重测信度、评分者间信度、维度、收敛效度和区分效度。
共纳入110例缺血性中风患者。FTT表现出令人满意的内部一致性（Cronbach's α = 0.70 - 0.75）、重测信度（ICC 0.88 - 0.99，95%CI）和评分者间信度（Kappa系数范围为0.83至1.00，P < 0.001）。探索性因素分析提取了一个用于工具选择的共同因素和两个用于动作执行的共同因素。FTT量表得分与MoCA之间存在轻度至中度相关性（范围为0.37至0.50），表明具有令人满意的收敛效度和区分效度。FTT量表得分与PTU之间存在中度相关性（范围为0.49至0.51），表明具有令人满意的同时效度。左脑损伤患者在选择、制作和执行常用工具时肢体失用症的患病率分别为14.9%、8.5%和8.5%。而右脑损伤患者在类似任务中的失用症患病率分别为3.0%、0%和0%。
FTT在评估中国缺血性中风患者的肢体失用症方面是可靠且有效的。
