title: Psychometric comparison of the shortened Fugl-Meyer Assessment and the streamlined Wolf Motor Function Test in stroke rehabilitation.
abstract: 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.
  
  
  METHODS
  Test-retest design.
  
  
  METHODS
  Departments of physical medicine and rehabilitation at three hospitals.
  
  
  METHODS
  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.
  
  
  METHODS
  PARTICIPANTS received one of three rehabilitation therapies for three weeks and were evaluated at baseline and end of treatment.
  
  
  METHODS
  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.
