Assessing the streamlined Wolf motor function test as an outcome measure for stroke rehabilitation

Neurorehabil Neural Repair. 2011 Feb;25(2):194-9. doi: 10.1177/1545968310381249. Epub 2010 Oct 14.


Objective: 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.

Methods: 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).

Results: 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).

Conclusions: Compared with the original scale, the streamlined WMFT showed improved clinical utility.
