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.
