研究背景上肢Fugl-Meyer评定量表（FMA-UE）的心理测量学特性已被许多研究所证实。虽然存在几个修改版本的FMA-UE形式，其结构效度尚未完全建立。ObjectivesTo assess the structural validity and internal consistency of the original，short，and hypothesized FMA-UE forms.MethodsIn this cross-sectional，multicenter，observational study，the factor structure was assessed using confirmative factor analysis（CFA）to evaluate the adequate model of each hypothesized FMA-UE form（原始、30项、27项和6项表格）。每个FMA-UE形式和分量表的内部一致性进行了评估，使用Cronbach的α因子结构evaluation.ResultsWe招募了363例首次发作中风（中位年龄= 70.0，中位数天= 75.0）。原始模型的结果没有用验证性因素分析进行估计。在所有FMA-UE表格中，30项表格缺少三个反射项（4因素，30项目模型）和27项目模型缺少3个反射和3个协调项目（3因素27项目二阶模型）;这些形式证明了适当的模型适应性（近似均方根误差= 0.056/0.059，比较拟合指数= 0.995/0.996，Tucker-Lewis指数= 0.995/0.995）。6项表显示模型拟合较差。结论30项和27项FMA-UE量表具有良好的因子结构，可用于临床实践。然而，未来的研究应确定的因素结构的6个项目的形式。
BackgroundMany studies have confirmed the psychometric properties of Fugl–Meyer Assessment of the upper extremity (FMA-UE). Although several modified versions of the FMA-UE form exist, their structural validity has not been fully established.ObjectivesTo assess the structural validity and internal consistency of the original, short, and hypothesized FMA-UE forms.MethodsIn this cross-sectional, multicenter, observational study, the factor structure was assessed using confirmatory factor analysis (CFA) to evaluate the adequate model of each hypothetical FMA-UE form (original, 30-item, 27-item, and 6-item forms). The internal consistency of each FMA-UE form and subscale was assessed using Cronbach’s alpha after factor structure evaluation.ResultsWe recruited 363 patients with first-episode stroke (median age = 70.0, median days = 75.0). The results of the original form models were not estimated by CFA. Of all FMA-UE forms, the 30-item form lacked three reflex items (4-factor, 30-item model) and the 27-item form lacked three reflex and three coordination items (3-factor, 27-item, second-order model); these forms demonstrated an adequate model fitness (root mean square error of approximation = 0.056/0.059, comparative fit index = 0.995/0.996, Tucker–Lewis index = 0.995/0.995). The 6-item form demonstrated a poor model fit. All FMA-UE forms and subscales showed a high internal consistency (Cronbach’s alpha>0.91).ConclusionsBoth 30- and 27-item FMA-UE forms showed a good factor structure; therefore, these forms are eligible for use in clinical practice. However, future studies should define the factor structure of the 6-item form.
