Abstract
Objective:
To examine the criterion validity of lower extremity Motricity Index scores.
Design:
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.
