This study investigates the clinimetric properties of the streamlined Wolf Motor Function Test (WMFT), a 6-item version of the performance time scale of the WMFT.
The streamlined WMFT, along with 2 criterion measures, the Fugl-Meyer Assessment (FMA) and the Stroke Impact Scale (SIS), were administered to 64 stroke patients before and after a 3-week intervention. Responsiveness was examined using the Wilcoxon signed rank test and standardized response mean (SRM). Criterion-related validity was investigated using the Spearman correlation coefficient (ρ).
The mean score on the baseline FMA upper extremity of the patients was 44.84 (standard deviation = 12.77). The streamlined WMFT and the original performance time scale showed comparable responsiveness (SRM = 0.29 and 0.37, respectively). The concurrent validity of the streamlined WMFT was good (ρ = 0.57-0.69). For predictive validity, the streamlined WMFT showed slightly better association with the criterion measures (ρ = 0.60-0.68) than did the original scale (ρ = 0.56-0.64).
Compared with the original scale, the streamlined WMFT showed improved clinical utility.
本研究调查了简化版 Wolf 运动功能测试（WMFT）的临床计量学特性，该测试是 WMFT 表现时间尺度的 6 项版本。
在 3 周干预前后，64 名脑卒中患者接受了简化版 WMFT 以及 2 项标准测量工具，即 Fugl-Meyer 评估（FMA）和中风影响量表（SIS）。使用 Wilcoxon 符号秩检验和标准化反应均值（SRM）来评估反应性。使用 Spearman 相关系数（ρ）来研究标准相关效度。
患者基线 FMA 上肢的平均得分为 44.84（标准差=12.77）。简化版 WMFT 和原始表现时间尺度显示出相当的反应性（SRM 分别为 0.29 和 0.37）。简化版 WMFT 的同时效度良好（ρ=0.57-0.69）。对于预测效度，简化版 WMFT 与标准测量工具的关联稍好（ρ=0.60-0.68），而原始量表的关联稍差（ρ=0.56-0.64）。
与原始量表相比，简化版 WMFT 显示出了改善的临床实用性。
