title: Assessing Wolf motor function test as outcome measure for research in patients after stroke.
abstract: OBJECTIVE
  The Wolf Motor Function Test (WMFT) is a new time-based method to evaluate upper extremity performance while providing insight into joint-specific and total limb movements. This study addresses selected psychometric attributes of the WMFT applied to a chronic stroke population.
  
  
  METHODS
  Nineteen individuals after stroke and with intact cognition and sitting balance were age- and sex-matched with 19 individuals without impairment. Subjects performed the WMFT and the upper extremity portion of the Fugl-Meyer Motor Assessment (FMA) on 2 occasions (12 to 16 days apart), with scoring performed independently by 2 random raters.
  
  
  RESULTS
  The WMFT and FMA demonstrated agreement (P<0.0001) between raters at each session. WMFT scores for the dominant and nondominant extremities of individuals without impairment were different (P</=0.05) from the more and less affected extremities of subjects after stroke. The FMA score for the more affected extremity of subjects after stroke was different (P</=0.05) from the dominant and nondominant extremities. However, the FMA score for the less affected upper extremity of individuals after stroke was not different (P>0.05) from the dominant and nondominant extremities of individuals without impairment. The WMFT and FMA scores were related (P<0.02) for the more affected extremity in individuals after stroke.
  
  
  CONCLUSIONS
  The interrater reliability, construct validity, and criterion validity of the WMFT, as used in these subject samples, are supported.
