OBJECTIVE: We aimed to compare the responsiveness, concurrent and predictive validity of the shortened Fugl-Meyer Assessment (S-FMA) and the streamlined Wolf Motor Function Test (S-WMFT) in persons with subacute stroke. DESIGN: Test-retest design. SETTING: Departments of physical medicine and rehabilitation at three hospitals. PARTICIPANTS: PARTICIPANTS with first-time stroke (N = 51; 38 men, 13 women; mean age ± SD, 55.1 ± 11.7 years) based on scores of Mini-Mental State Examination and Brunnstrom stage. INTERVENTIONS: PARTICIPANTS received one of three rehabilitation therapies for three weeks and were evaluated at baseline and end of treatment. MAIN OUTCOME MEASURES: Responsiveness was examined using the paired t-test and the standardized response mean (SRM). Criterion validity was investigated using the Pearson's correlation coefficient (r). RESULTS: Changes from baseline to end of treatment assessed by both tests were significant (P < 0.001). The value for responsiveness of the S-FMA was significantly higher than that of the S-WMFT (SRM difference, 0.48; 95% confidence interval, 0.23-0.63). There were stronger associations between the comparison scales and the S-FMA (r = 0.57-0.68) than with the S-WMFT (r = 0.39-0.58). CONCLUSIONS: The S-FMA had better concurrent and predictive validity than the S-WMFT and was more sensitive to changes caused by rehabilitation therapies. The S-FMA is recommended for expedited assessment of arm motor function outcome in stroke patients receiving rehabilitative therapy.
