Wolf Motor Function Test (WMFT)

 

Wolf Motor Function Test (WMFT) Evaluation Summary

  What does the tool measure? The WMFT quantifies upper extremity motor ability through timed and functional tasks.
  What types of clients can the tool be used for? The WMFT can be used with, but is not limited to clients with stroke.
  Is this a screening or assessment tool? Assessment
Time to administer The WMFT takes approximately 30 minutes to administer.
  Versions The original version (21 items), and the modified version (17 items)

Measurement Properties
  Reliability – Two studies examined the internal consistency of the WMFT and reported excellent internal consistency using Cronbach’s alpha.
– Two studies examined the test-retest reliability of the WMFT and reported excellent reliability using Pearson and Intraclass correlations coefficients (ICC).
– One study examined the inter-rater reliability of the WFMT and reported excellent inter-rater reliability using the ICC.
– Four studies examined the inter-rater reliability of the WMFT and reported excellent reliability using the ICC.
  Validity Content:
No studies have reported the content validity of the WMFT.
Criterion:

Two studies examined the concurrent validity of the WMFT and reported moderate to excellent correlations with the Fugl-Meyer Assessment, as the gold standard measure.
One study examined the concurrent validity of the WMFT and reported excellent correlations with the Action Research Arm Test.
Construct:
Known Groups:
One study examined the known groups validity of the WMFT using Wilcoxon Test and reported that the WMFT is able to discriminate between healthy individuals and those with upper extremity impairments.
  Floor/Ceiling Effects No studies have examined floor/ceiling effects of the WMFT in clients with stroke.
  Does the tool detect change in patients? No studies have examined the responsiveness of the WMFT in clients with stroke.
  Acceptability The WMFT is the widely used as an outcome measure for constraint-induced movement therapy.
Feasibility The administration of the WMFT is quick and simple.
