title: Criterion validity of lower extremity Motricity Index scores.
abstract: OBJECTIVE
  To examine the criterion validity of lower extremity Motricity Index scores.
  
  
  METHODS
  Retrospective cross-sectional comparison of lower extremity Motricity Index scores and hand-held dynamometer measurements obtained from 15 patients with stroke.
  
  
  RESULTS
  For individual actions (ankle dorsiflexion, knee extension and hip flexion) and all actions combined, Pearson correlations were good to excellent (r= 0.78-0.91), significant (p < 0.001), and of high power (> or =99%).
  
  
  CONCLUSIONS
  The findings of this study support the criterion validity of the lower extremity Motricity Index.
