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.
