Abstract
Objective To compare the responsiveness of the Rasch-calibrated 37-item Fugl-Meyer motor Scale with that of the 12-item Fugl-Meyer motor scale at both an individual and a group level. Design Repeated-measurements design. Setting Medical center. Participants Patients (N=301) 14 days after stroke. Interventions Not applicable. Main Outcome Measures 50-item Fugl-Meyer motor scale, 37-item Fugl-Meyer motor scale, and 12-item Fugl-Meyer motor scale. Results The patients were assessed with the original 50-item Fugl-Meyer motor scale 4 times, at 14, 30, 90, and 180 days after stroke onset. The patients' responses were used for estimating the Rasch scores of the 37-item Fugl-Meyer motor scale and 12-item Fugl-Meyer motor scale. The effect size, standardized response mean, and paired t test were used to compare the group-based responsiveness of the 3 forms (50-item Fugl-Meyer motor scale, 37-item Fugl-Meyer motor scale, 12-item Fugl-Meyer motor scale). Individual-level responsiveness was compared based on the significance of change between the 37-item Fugl-Meyer motor scale and 12-item Fugl-Meyer motor scale. Because up to 13 items of the 50-item Fugl-Meyer motor scale did not meet the Rasch model's assumptions, the significance of change of the 50-item Fugl-Meyer motor scale was not calculated. At the group level, the FM-37 and FM-12 Fugl-Meyer motor scale had sufficient and similar responsiveness. At the individual level, the FM-37 Fugl-Meyer motor scale detected more patients with significant improvement than the FM-12 Fugl-Meyer motor scale. The SC values and category distribution of the FM-37 Fugl-Meyer motor scale were significantly better than those of the FM-12 Fugl-Meyer motor scale (P<.001). Conclusions Although the group-level responsiveness of the 12-item Fugl-Meyer motor scale was sufficient and very similar to that of the 37-item Fugl-Meyer motor scale, the 37-item Fugl-Meyer motor scale had better individual-level responsiveness. The 37-item Fugl-Meyer motor scale is suggested as an outcome measure for both clinicians and researchers. ? 2014 by the American Congress of Rehabilitation Medicine.
